My Phoenix MultiPlus 24/3000/70 ends up in 'overload' state when it is charging, with a minimal AC load (< 100W), with the AC current limit set to 16A. The current to the battery is then 55A.
If I limit the AC current to 8A, the MultiPlus continues to charge, albeit at 45A.
I would expect the unit to limit itself to stay out of overload.
Can there be other causes of 'overload', apart from the AC load current ?
Firmware is 1812141.HEX
