Two Battery Bank Question
I recently installed a 2nd battery bank that is connected through a transfer switch that switches between shore power and Inverter Power. This new addition has a battery charger that is powered throug...

I have had split banks something like that. Did it manually though, no transfer switch. I had the same issue with that where the bank for the usual 12v loads got too low but there was still lots of AH in the inverter's bank but couldn't get at it.
Anyway, the solar controller (IMO no facts) will still only see one bank when they are paralleled. Whichever bank it is on will not be fully charged while it "equalizing" (be careful using that word to not confuse with over-voltage equalizing of a battery to desulphate it) so it will charge it and so also the other.
I had two different controllers with their own panels, One set for each bank.
The OEM bank will be neg grounded to the frame. The bank for the inverter does not have to be grounded to the frame at all--just the wires to the inverter. When you parallel the two banks that will neg ground the inverter bank too if that is an issue.
