MultiPlus-II 48/5000/70 safe to apply 220VAC on the output side when turned off?

Using this in a fixed caravan, shore line is only 4 Amps and my wife wants to use her Senseo Coffee machine (2,700W max.)

Issue is: when the MP-2 is turned off, there is no power in the caravan. Would have been a nice option to be able to switch to bypass the MP and supply the 4 Amps to the caravan when off.

So my actual question is: If I wire the MP after a whip switch that either supplies shore power to the MP or the Caravan directly, will the 220VAC that is then on the output side of the turned off MP-2 cause any problems?

btw. not a lot of options to choose from in the Topics list.

Hi @Reginald Gerard

Not safe!


Do -not- apply grid to the output of the inverter, this -will- damage it and it is not covered by warranty.

m.Lange Thank you for that. I should have been able to come up with that, maybe getting old and set im my ways. Will apply that suggestion. Daniël, good to know, just wanted to be sure.

I would recommend you to always switch L and N not only L.
