Before you start doing anything, you need to find out if you have a "smart" charging system ! With the house batteries disconnected and the engine NOT running, turn on the headlights and leave them on for 5 minutes. Now start the engine.
Check the voltage at the battery. It should be 14.0V-14.5V. Drive for at least 10 minutes. With the engine still idling, check the voltage at the battery. If the voltage is below 13.8V at the engine starting battery, you have a smart charging system.
A smart charging system WILL NEVER FULLY CHARGE A "HOUSE BATTERY BANK" !
If that is what you have, the best bet is to purchase a DC-DC battery charger. Not only does it does it provide isolation, but it boosts the supplied voltage to properly charge your house battery bank.
Likely your house battery bank is dead. Replace those dual Group 24 batteries (in parallel) with two 6V golf cart batteries (in series). They will provide a lot more power.
