Thank you for the rapid response and input!
I am powering the new seconday 3000W inverter with the lithium batteries so I can run 1500 microwave or brief Air Conditioning (1350W) when boondocking. Yes I am feeding the inverter with 4/0 AWG from a battery cutoff switch and have large AWG wires from each battery negative terminal.
Each battery also separately fused upstream of the battery positive cutoff switch.
Just told by WFCO tech support to make sure the circuit breaker to the primary (factory) inverter is shut off when running seconday inverter.
I can trace it our, but does someone already know which breaker?
From top down on the WF-8955PEC my breakers are:
30A (main)
1st dual 20A
2nd dual 20A
single 20A
Thank you!
