AC out 1 Breaker(s)?

I am using a Victron multiplus 3000 in a off-grid cabin. The cabin will not be connected to the grid/mains power. Everything in it will be 110 volt. All the breakers in the breaker box are connected to one line. I will not be using a generator so there will be no way of using/needing the power assist. I'm trying to figure out what type and how many breakers to use.


I was reading the manual and found the wording for AC-out-1 a bit ambiguous and needed clarification. Is this saying I need a earth leakage circuit breaker and then a second circuit breaker? I am not sure why I would need two of them. Thanks for your assistance.

Which model multiplus exactly? And which manual? I suspect a mix of 110/230V specs here.

A GFCI and a fuse/circuit breaker are not the same.

The GFCI is a ground fault protection and protects you from getting shocked.

A fuse/circuit is an overcurrent protection for the wire.

But there are also combinations of GFCI and circuit breaker available.

Victron has a really useful schematics page for the MultiPlus 3KW-24V-120V-AC.
