Hello, one of my first forays into solar was a Harbor Freight 100w "Thunder-something" pack w/ PWM charge controller. Since then I've introduced a proper solar system with Rich Solar 100w panels, an MPP Solar 24v CC & inverter combo unit and a 92ah LiFePO4 24v battery.
My question, though, is - on that cheap HF PWM that's hooked up to my 35ah 12v battery - is there a way to know if it's shutting down the battery draw automatically when the batteries get to the LVC? I believe the PWM has an LVC setting currently set at 11.9v (good or bad #, idk). Seems that when the battery gets down to 11.9v the little DC LED light that came with the system and that I've got running off it begins to flash slowly but steadily; but I don't know if the PWM is actually "protecting the battery" by preventing further discharge?
I know these HF systems are kinda on the low-end side of things, but do you think this PWM that comes with the "Thunder-something" pack is "doing its job" of protecting the battery vs. just letting the battery get to low and thus ruined?
Thanks for your input!
