We are in the process of setting up two AC500 and four B300S in split-phase output mode and have a problem with charging. When not in split-phase mode, they charge perfectly off of our sine wave 14kwh generator. Both are sharing a 15A outlet for charging and are set to charge at a rate of 7A. All good so far.
With nothing connected to the inverter AC output outlets, we can configure one as a split-phase master and the other as a slave with the communication cable connected. We can enable AC output (again with no load yet) and it too seems to work fine. No alarms once they’ve started talking to each other.
However, when AC output is enabled and the inverters are plugged in for charging, alarms start.
024. Phase Integration Error
061. Multi Communication Error
063. Multi Synchronization Error
Alarms persist until we disable AC output and then revert to single phase mode. Only then will they start to charge again. Can this be resolved so the system can stay in split-phase AC output mode while charging as well?
