Multiplus /12/1600/70-16 defaults to error on sudden load

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?
Best regards

Drills are "noisy". Does any other less noisy 350 watt load cause the same problem.

Are you running on battery power? Measure the battery voltage at the terminal on the Multiplus. Battery fully charged?

if the travel iron is using a diode for low power then its only using half the cycle ie the top or bottom half of the cycle thus this makes the unit only 800VA or about 650 watts so you maybe overloading it. and also the battery may not be able to deliver the required amps a

Other wise I sugest that yiou give amps and voltage readings and the battery size at the time of shutdown
