What Rick & John said.
If those 3 batteries have been sitting there since 2012, they're likely
past their end of life and no longer reliable. A "run of the mill" marine
battery will last only 5yrs. A cheap (Walmart) marine battery, maybe
3yrs. I'd replace them and/or do a load test on them (with a heat gun or
hair dryer).
To operate reliably, the system you describe requires decent quality
"storage" batteries. Even a *deep cycle* marine battery is not a good
solar system *storage* battery. The cheapest (in the short run) reliable
solution is to use flooded lead acid golf cart or forklift batteries. The
cheapest (in the long run) solution is LiFePO4.
For solar system storage battery info, see DIY Solar Power with Will Prowse

others on YouTube.
