Many people think that having a solar PV system means they will have electricity during a power cut. This is not the case. All solar PV inverters will automatically shut down during grid failure, to avoid feeding electricity back into the grid, and electrocuting engineers working on the lines!
Energy Jump can offer a solution which will allow your PV system to continue generating (meaning more Feed-in-Tariff for you), and keep your lights, fridge, internet etc on. An SMA near-grid battery storage system will ensure that you are not disturbed by a power cut.
