All brands Systems with battery storage fault codes
Add a third live source that is independent of both sun and grid. Tesla’s instruction not to troubleshoot during a grid outage exists because the battery is energising the house at that moment, and GivEnergy’s owner guide says battery systems contain high-voltage components and must not be opened or tampered with.
Codes on the Systems with battery storage follow the same All brands scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.

- Inverter shutting down in the middle of the dayUsually the grid rather than your system. Inverters must disconnect when mains voltage goes outside the G98 protection settings, and exporting solar is what pushes it there.Usually simple to fix
- Generating less than expectedThe rated figure is a laboratory number a British afternoon rarely supplies. Two published non-faults explain most of the rest: darkness and export limits.Usually simple to fix
- Battery not dischargingBefore treating it as a fault, check what your tariff is asking. A battery holding charge in the evening is very often following a schedule correctly.Get it checked
- Panels are still liveThere is no switch that stops a panel generating. Turning the inverter off makes it safe to stand next to and leaves the roof wiring live at hundreds of volts.Stop — call an engineer
