Hi everyone, on commissioning a 5kW Sunsynk, with load isolated, PV charging batteries  and inverter Normal indication ON. When the GRID supply is switched on the supply voltage of 230V is registered but after the 60 second timeout the main the Main Grid supply CB trips. Can anyone help on this problem?

    What was the load connected to the inverter while the grid was off and after you switched the grid on.
