I had a 3 amp, maybe 5amp, solar charger similar to that while in storage, I had the negative cable disconnected from the ground of the rv so no parasitic drains, had the + lead of the charger connected to battery #1 & the - lead connected to battery #2, checked the water levels monthly & this kept the batteries at 12.7+ volts every time I checked them. The difference was the storage was at home, no fear of the charger walking off & in Arizona so plenty of sunshine.
