![]() ![]() It's important to work out how much electricity you want to store for daily use and how much you want to keep in reserve in case a power cut should happen. The larger the capacity of the battery in kW, the more energy you can reserve for power cut back-up and the more appliances you'll be able to run during a power cut. In a solar battery back-up system, the battery needs to hold enough power for your everyday use while keeping some energy in reserve in case a power cut happens. This depends on the size of the inverter in the battery. How much electricity can a back-up solar battery provide? However, if the battery inverter is larger than the solar inverter, energy can continue to flow into the battery until it is fully charged. This is in part due to the fact that the battery inverter is usually smaller than the solar inverter allowing the energy in the solar inverter to flow into the battery could overload it. ![]() Some lower cost batteries will automatically discharge their stored energy when a power cut is detected. This depends on the type of back-up system you have. Will your solar panels continue to charge the battery during a power cut? This feature is called UPS (Uninterruptible Power Supply). Some systems provide an almost seamless transition from grid power to solar back-up power so you may not even notice that there has been a power cut. You'll have power for your home so you can continue to use your electronic appliances, appliances and any electric heating during the power cut. ![]() This relay is installed between your main fuse board and the incoming electricity supply. Solar batteries with back-up power have a relay (a switch) which will automatically disconnect your electricity supply from the grid when it detects a power cut. However, if your solar battery has back-up functionality, you will be able to use your solar energy during a power cut… Solar batteries with back-up power…how do they work? This is why solar inverters are designed to automatically switch off when a power cut is detected. During a power cut engineers will be working on the grid and if solar panels or batteries are in operation there is a risk the engineers could be electrocuted by the electricity being generated. Your solar panels and battery are connected to the main grid. The reason why solar batteries often won't provide your home with back-up power is due to the safety risks involved in doing so. Solar batteries and power cuts…what usually happens? Get Free Solar Battery Quotes: Get quotes and compare prices. While there are some solar battery systems which do have this feature, it is far more common that a solar battery cannot help you in a power cut. ![]() While solar batteries can maximise your energy savings and lower your carbon footprint even further, many people assume that a solar battery will also be able to provide you with back-up energy during a power cut. This means you can use even more of your renewable and free electricity and buy less from your supplier. For example, at night or on particularly cloudy days when your panels aren't generating as much energy. When you don't use all the energy generated by your solar panels during the day, a solar battery can store the excess so you can use it at another time. Here's what you need to know about solar batteries and power cuts. Did you know that not all solar batteries can provide you with back-up electricity in a power cut? In fact, for safety reasons, it's more common that they don't have this capability. ![]()
