Good info! Will's channel is a fantastic resource.
Here's a good one I like if you're interested in doing this in your RV

Here's a good one about different battery types and what they do: https://www.youtube.com/watch?v=ZJD19RogRtg&list=PLrrS07NUXCMfAITcK7kkwEva7AZjhFPJH&index=7

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, or hundreds of others on YouTube.

My emergency contingency consists of 3 solar panels totaling 200+ watts charging 3 Marine 12v batteries, then hooked up to an 2000 watt inverter.  All to run a 7 cubic foot chest freezer a couple of fans and some lights.  Had this since 2012 "end of the world scare" but never actually used in an emergency until our BIG freeze.  It failed!!Everything was charged up and working except my inverter.  When hooked up it made a beeping sound and then shut down.. I read somewhere that they might have an internal battery that might have failed.  Any thoughts?
