Hello, I have an offgrid 3 phase system, 3x Multiplus 48/15000 200-100, with a large LFP 52 volt battery bank. 40kwp of PV solar.
I need more solar, and more battery. I have a second building 200 meters away and plan to install another 20kw PV Solar, a Fronius Gen 24 plus and a BYD Battery (Fronius only works with expensive High voltage batteries I understand).
Can this system , or a variation of something like it, be AC coupled to the victron system?
The goals are:
REDUNDANCY in case my victron system fails, its batteries catch fire, is in service
Increased battery capacity
increased solar
the Victron installation room is totally maxed out space wise also.
