Re: newbie looking for reassurance!
With fridge and pump loads, I'd stay with 24v. The 300w 12v inverter Bill mentioned is nice (I use one), but won't likely start the fridge, and maybe not the pump. With your existing inverter you can…2 · -
Re: newbie looking for reassurance!
A 20a controller might "accept" 800w of panel, in the sense that it can be overpanelled to that extent. 800w ÷24v charging = 33a, or ~50% more than the controller rating. Realistically, 800…2 · -
Re: Taking accurate voltage readings of batteries?
I've read that FLA batteries take a few dozen cycles to "form the plates" and reach full effective capacity. I'm not sure exactly what's involved physically/chemically in that process, but …1 · -
Re: Taking accurate voltage readings of batteries?
It seems to me the strings will tend to converge in voltage over time while resting, and diverge when under significant charge or discharge. As such, individual battery voltages at rest are of limite…1 · -
Re: Electrical problem I think??
It does sound like there may be an electrical/connection issue. I'd start by trying each panel individually on the pwm controller to see if one panel is bad or has a problem connector. In doing so, c…1 ·
