I recently ungraded my domestic bank from 100AH to 330 AH, and had to disconnect the solar controller to do it. Unfortunately, I didn't follow the order of disconnection/reconnection when doing it, and now, I'm not getting the rate of charge I expect, and used to get. It's an Epever Duoracer twin battery MPPT controller connected to 2 x 100w panels.
I don't recall the current I used to get, but the domestic voltage used to go down to around 12.2v overnight running a fridge, but build up to 14-odd volts during the day, while now, it rarely goes over 13v, with just a couple of amps going in. Have I wrecked it?
