Master Inverter using 1.4kw from the grid when PV available
Have 2 x 8Kw inverters, the Master is now consuming 1.4Kw from the Grid even though there is PV and battery available the slave is only consuming 40 watts. I have confirmed this using tounge ammeter (6.3 amps) around inverter cable and the utility meter.
Why is it consuming such a large amount?

Is your system setting for the very time slot not perhaps set to charge battery from the grid to a certain %, whilst the battery at that stage was below the set %
