Hello, I'm putting together my backup solution (minus solar for now). Attached is a picture of the whole solution (up to this point). Please let me know if this all makes sense.
I'm looking at:
2 Rosie Inverters
2 15kWh Batteries
Adding a Critical Load Panel
Couple of questions
a. I think the 150a BMS might be too small, since 300a x 48v = 14,400w, and the 2 Rosies can surge way above that. But even if I have 200a BMS, that seems to limit me on the surge side.
b. I'm considering the Victron Cerbo-S GX and the Smart shunt with the Lynx Distributor for all the data I can collect, but does it make sense to use the Victron eco system if I'm using the Rosie? (I can't seem to find if the Rosie has a similar setup for data).
c. Or, should I use the a 3rd party app like Solar Assist?
d. I'm not sure if the cost of the ePanel is worth it, but will definitely need the same set of breakers/fuses/cut-off switches etc, so it "will" keep it as an option to keep things clean.
e. Seems like I'm going into breaker overload if that is such a thing? For example, there will be a breaker on the inverter side and a breaker in the critical load panel and a breaker on the main panel into a breaker on the inverter.
f. I'm considering a fail over switch to the grid incase the inverters fail hard. Does that make sense? Would it be safe if I included generator interlocks for the specific breakers?
