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...

The batteries will drag the panel voltage down. It won't happen instantaneously. Let it rise to 16V then stop. A 30W panel will take quite a while anyways. You really need something with more oomph.
