I'm kinda interested on how the 24 VOLT DC SOLAR system batteries shown here would integrate with the RV Converter/Charger 12VDC Battery system.
Sort of sounds like this is a 120VAC 1500WATT stand-alone system that is only used for generating 120VAC using solar panels as the source of energy.
I'm guessing all of your 12VDC APPLIANCE like LIGHTs, BLOWER MOTOR, FANs, etc would remain connected to your RV 12VDC Battery system configuration when the SOL SOLAR system is being used..
My RV converter/charger unit alone pulls right at 120VAC at 1000WATTs by itself which would only leave some 500WATTs left for other 120VAC items you have in the RV setup
I'm probably missing something here on the SOL 24VDC SOLAR CONCEPT...
