Yes the solar controller is cheap. GoPower 30amp Pwm. Max i see at the batteries is about 8amps. No temp compensation.
Go Power is generally known for using higher quality components in there kits, and I also have there stuff and have had the system on my old 6V bank for 4 years now. there is a setting on the charge controller for agm or lead acid, maybe if it was set wrong that could be the issue.
my batteries were 10 years old when I started with the solar, and no issues over the last 4 years at all
is the converter a normal junky 2 stage converter, that is not set up for agm? if it is the first thing I would do is I got them to take that out and put in a proper 3 stage charger with equalization.
