House batteries not up to ah rating
Bought 2 new Interstate SRM-24 group 24 RV/Marine batteries a few months ago. I have used the MH 4 times on trips lasting from 3-6 days. Never going below 40 amps before recharging. The rating is 85...

Hi,
You need 60 watts per 100 amp-hours bare minimum and a charge controller. You need more than 14.6 volts. 15.4 if the battery is in the rv and about 16 if it is not.

Currently solar is charging one battery at 14.46v and 0.15 amp. I can do this every day if needed. Battery doesn't seem to want more amps
