I have EG4 6000XP . Can I keep the main breaker on when using the 6000xp with grid and load from inverter running into the same Breaker box as the main ?
Do not interconnect the load and grid, although I couldn't find this explicitly stated in the manual:
The EG4 6000XP is an off-grid inverter so isn't designed to back-feed power through the grid breaker, although it can pass through power from the grid to the load when the battery is drained to a user defined voltage / SOC.
