My system a MultiPlus II 48/3000/35 220V, with AC In connected to the grid, AC out to house loads, Earth disconnected from the Neutral (normal in Portugal), an 7 x Enphase IQ7+ on AC Out and a 48V 100Ah battery with BMS.
The system was working ok, with the ESS assistant installed and grid configured with EN50549 normal for Europe (and in Portugal because my IQ7+ are configure with this also).
But now the system don’t startup because of error #11 relay test fail.
What is more strange is the LED combination that is not on the manual:
Inverter blinking
Bulk blinking
Float on
Does any one knows what this mean?
Side note: Inverter works and charger too, if I setup grid as none. Even with grid configured with none, if it’s not inverting all excess PV production goes to the grid, meaning AC 1 Out → AC In 1.
