I don't know way this setting is not present in any eg4 inverter like in many other brand inverters. This makes the inverter go back and forth from grid to battery many times. Click, click, click. Possibly damaging internal relays. We should have the option of choosing when to come back to battery mode like when battery charge back up all the way to 90% or 100%
You can enable AC Charging, which allows the batteries to charge from the grid up to the specific percentage you set.
