Dear Forum First best wishes to all of you. My point for now: I have a small ESS system set up around a Multiplus compact 24V 1200/25. Once used in its original setting, (just inverter) it loaded the battery up with capacity.up to 600 Watt as per spec. I apply it now in ESS mode, external control configured in NodeRed. When charging the battery its loading-capacity is limited to 320 watt eventhough a setpoint higher is commanded via the “AC Power L1 Setpoint” label. The grid current limiter is set to 16 Amps so that should not be the issue. Anybody any idea? Thanks in advance.
