Solar Panels and Power Cuts

Do solar panels work during power cuts?

Standard grid-tied solar panels STOP generating during a power cut — this is a safety requirement (G99 regulations) to protect grid workers. To keep power during outages you need: (1) A hybrid inverter with EPS (Emergency Power Supply) — e.g., GivEnergy, SolaX, Solis. (2) A battery with enough capacity — 5-10kWh keeps essentials running 8-24 hours. (3) The inverter isolates from the grid and powers your home directly from solar + battery. Cost for backup capability: £5,000-£8,000 (battery + hybrid inverter). Without battery: solar stops. With battery + standard inverter: solar stops but battery drains. With battery + hybrid inverter: solar continues powering your home.
