I am installing a multiplus 2 to store solar energy and don't want the ESS function. I have a 3 x 25 amp 230 volt grid connection and want to use one phase to connect the multiplus 2.
This fase is extended to the barn where I want a fuse box with 3 16 amp groups, a 4000 watt solar inverter and the multiplus 2 connected to it. What ac brekers should I use for the extended fase and the multiplus two, I am using only the AC IN to load and unload the 20 kwh set of E-BOX 48-100 batteries
What size Multi? Also a diagram would help.
hi you have to calculate selectivity in your fuse system, so if grid is 3x 25A everything connected after that must be on a 16A breaker, the distributor in the barn can be on a 3x 16A breaker in your main fuse box
but if you want to distribute with another breaker panel in the barn everything behind that can be max 10A…
So you could run the multi on one of the 3x 16A wires that comes from the main fuse box, but you cant go higher..
I suggest you contact an electrical installer if your not familiar with electrical systems
