Could anyone please advise on the following scenario ...
Multiplus (12/1600/70-16) is operating on inverter with a constant load of approximately 60 W
An additional device (drill) is plugged in to the inverter outlet with maximum 350 W draw (I measured the peak of said device) and upon operation, the Multiplus effectively 'panics' and switches off, i.e., it doesn't switch graciously to AC IN 1 via UPS function, but switches to a situation of limbo. The inverter outlet is dead.
After about a minute, the unit recovers and switches back to inverter.
Any ideas what might be wrong?
