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.
