devide 230V input before multiplus, to feed a fridge

got a question:

is it possible to devide the 230V input signal (see drawing) to feed a fridge not over the multiplus (it has an automatic mode that should switch to gas, if no mains are available). I know that the multiplus 3K has an extra output for that, but not the multiplus 2k.


thanks!

ok thanks,

so there is no problem, when the multiplus switches N and PE together in inverter mode?


e.g. when running in inverter mode (PE and N together, no mains) and when suddenly shore power comes back, I might have N at the fridges PE conductor until the multiplus switches back? is that a problem? maybe for the GFCI/FI? or am I wrong?

I have to admit I'm no expert on ground connections...

But that has nothing to do with your refrigerator :)

Thanks so far! Great Help!

...just one more question (then I might be happy ;-)


In case of I would NOT Split the input signal and let everything run through the multiplus ( Standard config). Could I just take the RCD that I already have and wire it on the output instead after CEE Input? (When There is nothing in between CEE and multiplus) Or do I Need two RCDs anyway?

Which one is more „important“ ?

The CEE source (shore power?) should already have an RCD, I don't know what improvements can be made, will probably be different depending on the country / region also.
