Residential Battery Installation Our team of licensed electricians and battery designers/installers (NOT unqualified salespeople) will create a battery storage system to suit your situation. Electrical Sensations prides itself on installing high-end battery products, with top workmanship and good old fashion customer service. Battery Replacements Replacing an old or worn-out battery can make a big difference to how well your solar system works. Over time, batteries lose their ability to hold and deliver power efficiently. Replacing batteries helps you get more from your solar energy, save on your electricity bills, and keep your system running reliably for years to come. Commercial Battery Systems Battery storage helps businesses cut electricity costs by storing excess solar energy for use during peak times or overnight. By reducing reliance on the grid and avoiding high demand charges, batteries improve energy efficiency, lower overheads and boost profitability over the long term. Battery System Maintenance Regular battery maintenance is key to keeping your solar system running smoothly and efficiently. Checking performance, cleaning connections, and updating software can help catch small issues before they become big problems. Staying on top of maintenance means your battery lasts longer, works better, and continues saving you money over time. Battery System Upgrades Got a battery storage system that just isn't keeping up anymore? Newer batteries are more efficient, hold more energy and work smarter than old battery setups. Upgrading your battery storage can cut power costs even more and improve the overall performance, reliability, and lifespan of your system. Battery Grant Information Electrical Sensations is proudly qualified, licensed and accredited to design and install battery storage systems that are eligible for the Cheaper Home Batteries Program "Battery Grant". The Battery Grant saves you about 30% on the cost of installing a battery. Find more details about the Battery Grant in our News section . Things to Consider when thinking batteries. About Batteries in general Do I have enough surplus solar power to charge the battery? Do you have somewhere the battery can installed? There are many (MANY!) rules regarding the positioning of a battery. Do you want the battery to give you power in a blackout situation? Do you know roughly how much power you use at night time? About the Battery Manufacturer How financially stable is the manufacturer? Do they have an Australian office to handle any potential future warranty issues? What is the manufacturer’s product warranty? Is it easy to understand or ridiculously difficult? What is the warranty claim/failure rate? About the Battery Itself What is the physical size and storage capacity of the battery? Can it be upgraded easily? Is it modular or stackable? Can it provide me power in a blackout situation? Can the battery inverter keep the panels producing power in a blackout on a sunny day? How many "boxes" are there to the battery system? Is it all in one cabinet or are there separate components required? What is it's usable capacity of the battery - i.e how much power will the battery give me to use? This is usually different to the kW size of the battery.

Looking for quality solar inverters to start up your solar power system? Let us provide you the core to power your home or businesses. At Electrical Sensations, our Clean Energy Council accredited designers have done the hard yards of researching and comparing the multitude of solar products available. We're totally confident in the performance, reliability and longevity of every product we choose to install. When you're investing in a solar power or battery system, you need the system to perform well for you, for as long as possible, without giving you any headaches. There are literally hundreds of different solar products on the market and it can be really hard to distinguish between them all. With solar power systems, the old adage “You get what you pay for” rings very true. We apply the following criteria when choosing which products to recommend to our customers: How long has the manufacturer been in existence and producing that particular product? How financially stable is the manufacturer? What is the general ‘reputation’ of the product from industry and consumer reports? Do they have an Australian office to handle any potential future warranty issues? What is the warranty claim/failure rate? Not only, what is the length of the warranty, but also how difficult and onerous is the warranty process? The devil can be in the detail of the warranty Terms and Conditions. Would I be confident and happy to have this product installed on my home? Solar Inverters The inverter is the heart of a solar power system. It converts the DC output of the solar panel to AC power that is used by your home appliances. With a sub–standard solar inverter, your solar power system is at best, under–performing and at worst, an expensive white elephant on your roof. Choosing an inverter is an important decision and one that warrants significant research and investigation. There are many different brands of solar inverters and the variance in terms of quality, performance and longevity is huge! The most common inverter sizes are 5kW and 10kW for single-phase and 5kW, 10kW, 15kW and 30kW in three-phase options. Most commercial solar installations are 3-phase starting at 10kW. There are three types of solar inverters/configurations; String Inverters, Microinverters and Power Optimisers. 1 STRING INVERTERS String inverters, like SMA and Fronius, are the most commonly installed inverter in Australian. Their job is to convert the DC power to AC. String inverters are usually located in a central location – commonly beside the switchboard or in the garage. There is typically only one central inverter per system. 2 POWER OPTIMISERS An optimised system consists of a small Power Optimiser mounted under each panel similar to a microinverter, plus a central inverter in a similar place to where DC string inverter would be located. SolarEdge Power Optimiser systems are well suited to installations that have shade issues or that require panels to be installed facing more than 2 directions . 3 MICRO-INVERTERS Enphase micro-inverters are used for more complex installations where there may be partial shading or panels tilted at various angles and/or panels facing multiple directions. An individual micro-inverter is installed under each solar panel, meaning that the number of panels = the number of micro-inverters needed. Solar Inverter Brands Known for its German engineering and design, SMA is renowned for producing reliable, compact, high performing solar inverters for the past 40+ years. Electrical Sensations is a proud SMA PowerUp Partner. SMA Read More Established in 1945, Fronius is an Austrian solar inverter manufacturer. Fronius inverters are globally recognised as amongst the industry’s highest-performing inverters. FRONIUS Read More Known for their long warranties, safety features and monitoring advantages, SolarEdge is a trusted brand that we recommend for our customers with more complex installations. SOLAREDGE Read More Enphase was founded in 2006 and manufactured the world’s first microinverter system in 2008. Since then, Enphase has grown exponentially and is widely considered the global leader in microinverter technology. ENPHASE Read More The Australian owned, designed and manufactured Selectronic inverters are regarded in the solar industry as the leading inverter for off-grid (stand-alone) solar and battery applications. SELECTRONIC Read More Things to Consider. What warranty is provided with the inverter and can it be extended? Does the manufacturer have a reliable service network in Australia and/or allow the installer to carry out minor repairs? Is there an Australian office and how many people are in that office? Is it just a token office with a salesperson? Can you connect remotely to the inverter to see what power is being produced (online monitoring) or does it cost any extra to have that capability? Do you have reliable WiFi connectivity for remote online monitoring of your system? Do you want to be able to monitor your electricity consumption as well as solar production? Most inverters allow remote production monitoring but consumption monitoring usually requires a separate inverter Smart Energy Meter.

Electrical Sensations install Off Grid Solar Systems in Toowoomba and the Darling Downs region. Off Grid Solar Systems Reliability is paramount in off-grid solar power systems. Choosing quality components is important in all solar power system systems, but it is absolutely critical in off-grid systems. If you are in a remote area or where the cost of having power connected to your property is exorbitant, off-grid (stand-alone) solar power systems with batteries and generator backup are the solution. Off-grid solar power systems supply electricity to properties that are not connected to the electricity network/grid. These systems are also referred to as “Remote Area Power Systems” (RAPS) or “Stand-Alone Power Systems” (SAPS). Off-grid solar power systems are independent mini-power stations that create dependable and reliable electricity that is no different to that supplied by the national electricity grid. Whether it is for a small or large home, farm or weekender; an off-grid solar power system will generate reliable, clean and hassle-free electricity. Components of an Off Grid System Solar Panels – the panels absorb sunlight and convert it to direct current (DC) electricity. Inverters – Off-grid systems require two inverters: a battery inverter (eg Selectronic) and a solar inverter (eg Fronius). Battery – Stores energy for use when solar power is not producing, such as at night time or inclement weather. Generator – emergency back-up power supply. If you're considering going off-grid, give us a call to discuss options to suit your property. With off-grid solar systems there isn't a "one-size-fits-all" solution.

With an increasing number of EVs on the road, also comes an increase need for battery charging stations for these cars. Call us now for a full turnkey solution. Electric Vehicle Charging Whether you are looking for a low-cost Electric Vehicle (EV) charging station to get you started or a full turnkey solution, Electrical Sensations can create a solution for you. EV Charging Solutions for Homes and Businesses Electric vehicles (EVs) are becoming a normal part of life for many individuals and businesses alike. As more people make the shift to electric, access to reliable and well-installed charging infrastructure is becoming increasingly important. Whether you're looking to install a charger at home or at a workplace, it's important to understand your options—and what's involved in getting everything up and running safely. We install EV charging systems across a range of settings, tailoring each installation to the needs of the property and the people using it. Our work focuses on safety, compliance, and practical design to ensure the system fits your day-to-day requirements now and in the future. Understanding EV Charging: AC vs. DC There are two main types of EV chargers: AC (Alternating Current) and DC (Direct Current). Each serves a different purpose, depending on how quickly you need to charge and the type of setting the charger is used in. AC Chargers: Most common type for homes and smaller businesses Slower charging, but more cost-effective and easier to install Level 1 uses a standard household outlet (120V), typically adding 5–8 km of range per hour Level 2 uses a 240V connection and can add around 30–50 km of range per hour Suitable for overnight charging or vehicles parked for longer periods DC Fast Chargers: Delivers power directly to the vehicle battery, bypassing the onboard charger Much faster charging—can add 100–300 km of range in 30–60 minutes Higher power demand and more expensive to install Typically used in commercial or public locations, such as service stations, fleet depots, or shopping centres We help assess which type of charger best suits the location and your usage needs to fit with your available power supply. Residential EV Charging Installing an EV charger at home offers convenience and peace of mind—especially if your EV is your main mode of transport. Most homeowners choose Level 2 AC chargers, which strike a good balance between cost and charging speed. They’re also compatible with all major EV brands. Typical home setup includes: Site assessment of your current electrical system - firstly by photos and then a site visit Installation of a Level 2 AC charger Upgrades to the switchboard or circuit, if required Submission of forms to the electricity provider (E.g: Ergon) if necessary Optional smart charger setup, allowing scheduled or solar-based charging The installation process is usually completed within a day, and we work to minimize disruption during the process. Commercial EV Charging For businesses and property managers, providing EV charging can support staff, tenants, or visitors while contributing to sustainability goals or compliance with green building standards. The design and scale of the installation depend on expected usage, space available, and power capacity. Common considerations for commercial EV charging installations include: Quantity and type of chargers (AC for long-stay parking; DC for fast turnover) Load management to prevent overloading the electrical system User access and payment systems (public vs. private access) Integration with existing or future solar or battery systems We help plan installations with scalability in mind, so the system can be expanded as EV demand grows. Equipment and Compatibility There are many EV charger brands on the market. We work with a variety of trusted manufacturers and will recommend a unit based on your needs, vehicle type, and preferences. Popular brands include: Fronius Watt Pilot Zappi SigEnergy Chargers may also offer smart features like Wi-Fi connectivity, app-based control, usage tracking, and solar energy integration. If you're exploring options for EV charging at your home or business premises, we're here to help you move forward with confidence.

Frequently Asked Questions | Electrical Sensations Toowoomba Frequently Asked Questions. Solar Batteries Electrical Work Security cameras and alarms About Electrical Sensations Are the installers employed by you or are they subcontracted? All of our solar installers and electricians are our direct employees, not sub-contractors. Having our own in-house team means we deliver consistent quality you can trust. Our employees share our company values, receive thorough training, and strive to build lasting relationships with customers. Unlike sub-contractors who juggle multiple companies, our team is fully dedicated to your satisfaction and upholding our reputation. Do you offer finance for solar systems? We can put you in touch with financiers BUT we don’t provide interest-free finance options. Some of our customers have used Plenti and Parker Lane for finance – both of which have (at the time of writing) specific loans for solar and battery installations. Our customers report that both Plenti and Parker Lane are easy to get along with and make the process simple. Some of the major banks are now offering specific green loans for solar as well. Electrical Sensations is not a licensed financier and can’t give advice on which financial products to use. We prefer to leave arranging finance to the finance experts and we stick to what we do best – installing quality solar, battery and electrical systems. How many systems have you installed? We've installed more than 1,800 new solar power systems on homes and businesses throughout Toowoomba & the Darlings Downs region. We've also upgraded or repaired many more. Will solar panels stand up to hail? The short answer is yes, unless the hail is very big - all solar panels are designed to withstand tough weather, including hail. Quality panels are built with tempered glass, which is strong enough to endure average hailstorms. All solar panels that are on the Clean Energy Council (CEC) list of approved products that can be installed in Australia, are tested to withstand hailstones of around 25 mm. While no system is completely indestructible, the chances of hail damaging your solar panels are low in the Toowoomba area. We always advise customers to add their solar power and battery system onto their home and contents insurance, just in case. What size solar system should I install? Short answer - it depends! The size of your solar PV system will depend on: • The physical unshaded roof area available for the installation of your panels. • How much your current electricity bills are. • Your future plans for electricity consumption e.g: EVs, extra air con, pool, spa. • How much you are prepared to spend. • What portion of your electricity consumption you wish to generate. • What size Ergon/Energex will allow you to install. To work out what size solar PV system you require, you need to understand your household’s daily electricity consumption. As a rough indication, on average, a typical Australian household uses around 20-30 kWh of electricity per day. Around 6kW of solar panels is a good fit for that amount of usage. That 6kW system will produce an average of around 20-22 kWh of electricity per day, which can cover a large portion of your electricity needs. Using your current average daily electricity consumption, as well as your expected FUTURE consumption, we can size a system to suit you. Sizing a solar power system should definitely not be a ‘one size fits all’ process. Our team of Solar Accreditation Australia (SAA) accredited solar designers can help work out what size system will suit you best. How much do your solar systems cost? Our standard 6.6kW solar systems for a home in Toowoomba, tin roof, single storey, single phase, start at around $8,500 depending on the brand of inverter and panels. Three phase premises, tile roof installations, switchboard upgrades, main cabling upgrades and tilt frame installations are potential extra costs that might apply. What is the lead time for a solar installation? For residential systems, the lead time is generally 2-6 weeks depending on: a) Ergon/Energex application turn around time. Smaller residential systems are generally approved quickly, while larger commercial systems take much longer to progress through the electricity authority. b) The availability of components - panels and inverters etc.. c) Weather. Rain, strong winds and blistering heat waves make solar installations unsafe and just not possible. d) Time of year - October till December is the busiest time of year for most solar installers The expected start date and duration for the installation will be clearly stated on the agreement that forms part of the pre-installation documentation. How long do solar systems last? It depends! The solar panels and power optimisers that we use are warranted by the manufacturer for 25 years. So, technically they will last 25 years – because if something was to go wrong before then, it would be replaced under warranty. Inverters on the other hand have a warranty period of 5-12 years (depending on the brand). We have seen systems that have lasted and been producing power for 22 years and cheap, poor-quality installs that haven’t even lasted 1 year. Can I add batteries to my pre-existing solar system? Yes, you can! There are a lot of factors to consider though... Firstly need to have enough panels to produce the extra power needed to charge the batteries, or enough space on the roof to add additional panels. You also need permission from Ergon/Energex and a suitable location for the batteries to be installed. There are ‘all-in-one’ solutions available, such as SonnenBatterie, Tesla PowerWall, Sigenergy and Redback that have the battery/batteries as well as the battery inverter in one enclosure/stack. There are a lot of details to get right when designing hybrid solar power systems. It isn’t as easy as grabbing any cheap batteries off eBay and hooking them up. If you're considering batteries, give us a call. We'll be more than happy to go through the options for batteries with you. How much is the solar 'rebate' (STC Financial Incentive)? It depends! The amount of the 'rebate' depends on the size of the solar system, date of installation and postcode of the installation address. The bigger the system, the more the rebate. At the moment, the ‘rebate’ works out to be roughly around $350 - $400per kW installed. This means the total rebate you receive off the cost of a solar system is approximately $2,100 - $2,300 for a 6.6 kW system. Under current legislation, the amount of the 'rebate' reduces on 1 January every year. Do you do off-grid solar systems? Yes! Nigel is qualified to install both on and off-grid solar and battery systems (Solar Accreditation Australia Lic no. S2079911). There is a LOT to designing an off-grid solar power system to suit your specific requirements.

Can I still put panels on if I don't have a north facing roof? Absolutely! In fact, in some cases, east/west facing panels match the owner’s electricity usage better than a north-facing system. If you have the typical morning and afternoon spikes in usage, east/west systems can be preferable to a fully north-facing system. If I install solar, will I still get an electricity bill? There is no denying that getting solar can save you big bucks on your electricity bills, but will it completely wipe it out? The truth is probably not. While it’s possible, very few solar system owners completely eliminate their electricity bills anymore (unless they have batteries/off-grid). Here’s why: 1. Solar only works when the sun is shining. All of the electricity you use at night, you have to buy from Ergon/Energex (unless you have batteries). 2. Over time, electricity prices have risen and the feed-in tariff has reduced. With the current Ergon feed-in tariffs, you pay around 3 times more for the power you buy from Ergon than what they pay you for any surplus that is sold back. 3. Ergon/Energex also charge a daily connection fee which is quite substantial. How often should I clean my panels? Over time dirt, debris and dust can build up on your solar panels, creating a barrier that prevents the sun from reaching the solar panels. How often your panels need a clean depends on where you live and how dirty they get. If you are in town and your panels are on the pitch (not flat) then a clean every 6-12 months is usually enough. If you live on a dirt road, near paddocks or a construction site, have lots of trees or birds or bats, they will need more regular cleaning. Some may need a clean every couple of months, while others can get away with cleaning every 3-6 months or so. These times are only a guide – it really does just depend on how dirty your panels are. What does grid connected mean? Grid-connected means that the solar power system is connected to the electricity grid (the Ergon/Energex network) that currently supplies you with power. At night time and in periods of inclement weather, you will be buying power from your electricity supplier if your solar power system is not producing enough power to meet your consumption. Will my solar system work if there's a blackout? No. Unless you have batteries, your standard grid-tied solar power system will not operate during a blackout or power outage situation for safety reasons. The systems are designed to shut down the instant there is a power outage or blackout, to prevent back-feeding electricity into the grid, which could endanger Ergon/Energex workers. If you have a battery storage system integrated with your solar panels, your setup can continue to provide power to your home during a blackout. The battery storage will take over, supplying you with electricity from the stored solar energy. We can install battery backup solutions that keep your lights on even when the grid is down, providing you with reliable power and peace of mind. Reach out if you'd like more information or to discuss the best backup options for you. How do I maintain my solar system? Does it need to be serviced? Maintaining your solar system is important to ensure its long-term efficiency and performance and your savings. We recommend a few key steps for maintaining your solar system: 1. **Regular Inspections:** Periodically inspect your solar panels for any dirt, debris, or obstructions like leaves and bird droppings. Cleaning the panels with water and a soft brush typically fixes those issues. Avoid using a pressure washer (such as a Gernie), abrasive materials (such as steel cool or scourers) or harsh chemicals that could damage the panels. 2. **Monitor Performance:** Keep an eye on your system's performance through your inverter screen or the monitoring software portal or app. Look for any significant drops in energy production, and faults or errors which could indicate a need for maintenance. 3. **Shade Management:** Ensure that no new shadows or obstructions, like growing trees or newly erected structures, are affecting your panels' exposure to sunlight. 4. **Professional Servicing:** While solar systems are generally low-maintenance, it is advisable to have a professional service your system every year or so. Our team can check for potential issues such as loose connections, degradation, or wear and tear, ensuring your system operates at peak efficiency. Regular maintenance and professional servicing not only extend the lifespan of your solar system but also maximize your return on investment. Contact Electrical Sensations to schedule an inspection or service and keep your solar system running smoothly. Should I put in a solar hot water system as well as solar power system? While we totally support the installation of solar power systems, we believe the high up front cost of dedicated solar hot water systems is just too high for many home owners. A high-quality solar hot water system can easily cost more than $5,000, while an electric hot water system has a significantly lower upfront cost - typically around $2,000 - $3,000. By installing a timer for an electric hot water system and connecting it to the same tariff as your solar power system, you can achieve almost the same savings as with a dedicated solar hot water system—not quite, but almost! The cost saving from choosing an electric hot water system and a timer compared to a dedicated solar hot water system is huge. Can I wipe my electricity bill out if I install solar? Installing a solar power system will significantly reduce your electricity bills, but is not likely to completely eliminate them. Factors influencing the resultant savings from the installation of a solar power system include the size of the system, quality of components and and critically your household's energy consumption - in terms of both total usage and time of usage. For example, if you use most of your power through the night time, a solar power system won't save you much money off your power bills. However, if you can and WILL use as much of your power as possible through the day time, you'll save a whole lot more money off your power bills. If you have the choice of using an appliance through the day time of the night time, do it through the day time, while the sun is shining and the solar is producing. Similarly, we advise you to stagger your electricity usage if you can. A solar power system can only produce so much power at any one time, so if you use a lot of high-draw appliances at the same time (such as oven, dishwasher, microwave, iron, cooktop) the solar won't be producing you enough power and you'll be buying a large portion of your usage. Though some customers do achieve a zero electricity bill, they are absolutely the exception rather than the rule. Our team provides thorough assessments and tailored advice to help you understand the benefits and realistic outcomes of solar installation. What does export-limiting mean for my solar system in Queensland? Export-limiting is when the electricity provider (Ergon or Energex in Queensland) impose limits on the amount of electricity your solar system is allowed to send back to the grid. In Queensland, this is particularly relevant due to grid capacity limitations, aging infrastructure and the high saturation of grid-connected solar power systems. Even if your solar system produces a large amount of electricity, the amount that can be exported back to the grid might be capped at a specific level, such as 5 kW, to maintain grid stability. Export limiting (or dynamic control of export) is necessary for solar power systems with inverters greater than 5kW on single phase premises and greater than 15kW on three phase premises. In some areas though, it's possible that the export level stipulated by Ergon/Energex may be even lower than 5kW per phase. It's important to understand that when you have a grid-connected solar power system installed, you USE the solar production FIRST. If you need more it just comes seamlessly from the grid. If you're producing more than what you're using, it goes back to the grid, up to whatever level Ergon/Energex will allow. At Electrical Sensations, we ensure that your solar system complies with all Ergon/Energex regulations. By understanding and playing by the rules, we help you maximize the benefits from your solar investment while keeping Ergon happy. Why do you recommend more panels than the inverter size? Won't that damage the inverter? Solar inverter have a specific "AC rated capacity" e.g: 5kW but can handle more panels without issues, up to their design limits. Having more panels than the inverter size is known as "oversizing" or "over-clocking" the system, Most inverters installed in Australia are designed to take panels that are up to 133% of the inverter capacity. For example a 10kW inverter can handle up to 13.33kW of panels and a 5kW inverter can handle up to 6.67kW of panels. The Clean Energy Council and electricity supplier (Ergon/Energex) rules allow panels of up to 133% of the inverter capacity for standard grid-connected solar power systems. If you have batteries, some inverters can handle up to 200% panel capacity and that configuration is also approved by the CEC and the electricity suppliers. Why do it? In reality, solar panels will rarely producing their maximum power because conditions are rarely ideal. During early-mid mornings, mid-late afternoons, cloudy days and certain seasons, the energy production from the panels may be lower than the inverter’s maximum capacity. Installing a larger array (more panels) allows you to generate more power during the non-ideal times. Oversizing is a cost-effective strategy to ensure you get the most out of your solar investment. Inverters are designed to take more panel input than the inverter capacity and there is no additional wear and tear on the inverter. Oversizing does not shorten the life of a the solar system and in fact, the vast majority of solar systems installed have more panels installed than the inverter capacity. It is acceptable, approved and very much "the norm". All solar panels made in China are the same aren't they? No! Not all solar panels are the same - there can be a world of difference between them. A common myth (or story shared by some solar salespeople) is that "all Chinese solar panels are the same," but this simply isn't true! While it's true that China is a major producer of solar panels, there's a huge range of quality across different brands and manufacturers. Just like with any product, the quality of solar panels varies greatly based on the quality of the component materials, the manufacturing process, the technology behind them and the specs they are manufactured to. Many reputable Chinese manufacturers (and there are HUNDREDS of them) use the latest advancements in solar technology, ensuring high efficiency, durability, and long lifespans. On the other hand, some cheaper, lower-quality panels seem to have corners cut which leads to poor performance and a shorter lifespan. Top Chinese brands, like Sumec Phono and Aiko, SunPower are known for producing reliable, high-performance panels that are widely used around the world. These brands invest heavily in research and development to create panels that deliver strong energy output, even in the harsh Australian environment. They also offer warranties typically around 25-30 years to back up their products. When choosing solar panels, it's important to focus on the brand's reputation, the technology used, and the warranty offered, rather than assuming all panels from a specific country are the same.
