Ecoworthy MPPT + 6 volt batts
Just installed the ecoworthy controller with a 250 watt panel. I am trying to figure out what settings I should run ecoworthy on for my batteries. The batts are 2 6 volt Costco golf cart batteries. I ...

I use an Eco-W with my 255w panel and Interstate 6v batts.
That 15.3 is just for a shot of finishing at the end of the usual 14.8 stage. You don't use that with the solar. Also your inverter quits at anything over 15v.
I set the absorption voltage to 14.8 and the Float voltage to 14.5 (highest it will go or else I would use 14.8) when there will not be much daylight time left after the batts reach 14.8. The batts then get some absorption time at 14.5v
(The controller goes to float as soon as the batts reache the set absorption voltage.)
When daylight is longer, so they get to 14.8 earlier in the day, I set the float voltage to 13.6 which helps keep the water in the batts
The 6s do very well with that above settings. I check their SGs to confirm that.
