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 25a at 14.6v at 90%soc, and likely about 10-12a 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 3-5%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.
My 90% SOC marker is 5 amps per 110AH at 14.5v It is not perfectly accurate of course.
I set my Eco-Worthy to Vabs of 14.8v but as soon as it gets the batteries there the darn thing switches out of Bulk (MPPT) to Float (in PWM mode) The highest I can set Float is 14.5 and I see the Trimetric showing 14.4 so what ever the voltage really is, that is where it stays till it gets dark.
As it happens the 6s do seem to like that regime. I wanted to leave them at 14.8 till dark but not required to keep them from needing frequent overcharging.
I would not like to drop to 13.8 on solar while camping. Got to get as much done as possible in the mid-14s in daylight hours. They can float overnight.
