What would be involved to add a charger/inverter to the RV? any recommendations for the size / brand to buy? Thanks for the help, John
Here is my budget solar, inverter/charger and battery system in a 303RLS. I expect to use between 50 and 150 amp hours per day.

(2) SOK 206ah batteries $2,000
Renogy 40 MPPT solar charge controller $140
600 watts of solar panels $600
Xantrex XC 2080 inveter/charger $800
(2,000w inverter/80 amp charger)
Victron BMV 712 battery monitor $200

I do have a Champion generator for backup and the converter is still there but switched off at the breaker.

This is my second iteration of the system after a summer in SD and MT for 2 months with full sun to partial shade and limited hook ups. Then a winter trip to TX and AZ for 3 months including boondocking and partial hook ups.

Of all of this, I think the battery monitor is the most important component.

Hopefully this gives you some ideas.
