The company is ElitePowerSolutions. Larry from Starlight Solar, Yuma, AZ is their distributor.
This system is virtually identical to Technomadia's install who were kinda pioneers with these cells in RVs. https://www.technomadia.com/lithium/
Yes, it is a complicated system (you should see the wires!). This was before the drop-in Battleborn systems and such. All these parts including the brain are necessary, it keeps tabs on undervoltage, 16 individual cell temps and voltages, etc.
I know the manufacturer installed batt kill switch should be a step earlier, but the brain has its own main kill switch that shuts everything battery related down.
I want to retain all shore power and gen abilites, so no removal of parts.
I was hoping the 3 terminals on the brain were "one way", as in the converter DC could not backflow into batteries to charge. The company confirmed that is NOT the case and I would have a loop with the inverter running the show.
So, I think the easiest answer is to disable the converting part with a switch. That way I retain all 110 on inverter and can still use 12V from battery only. If on shore power, the converter can be easily switched back online.
