Low Amps from New Solar Install
I did my first solar install on the roof of my fifth wheel this weekend. Two Renogy 100w mono panels to a Solar30 controller via a 10AWG cable down the gray tank vent. In going through the displays o...

sorry, Amp hour capacity... it's 225.
Those puppies should accept about 12-13a at 14.6v at 90%soc, and likely about 5-6a at 95%soc. What this means is, they will accept all the amps those 200w of solar can produce very deep into the charge, before amps taper. Therefore, it will only be the last 3-8%soc that will see the 'cease charging' voltage. BFL has had good success at 14.4v on his 6's, and I know Mex has suggested lowering voltage to that, at the end of charging. So maybe try 14.4v instead of 13.8. So 14.6 - 14.8v bulk, then 14.4v abs/float.
