Hey all!
I am worried my Lifepo4 battery bank has been damaged from the cold but unsure how to tell for certain. I have 3 206ah SOK batteries in parallel for a 618ah battery bank. My system has been dying a lot as the weather turns colder and the sun is not so high in the sky.
I charged my system to full the other day with a smart charger, and drained the system to empty to see what I am working with. At about 390ah of consumed energy, my battery bank voltage dropped to 10.5V, and the system died. They are not the heated models and I tried to charge them using a smart charger last winter in cold temps because I’m an idiot.
I have 600 watts of solar, and I am also now noticing that even when parked in full sun, the bank is only charging up at ~230 watts. Would this be expected from November sun output or could damaged batteries also be reducing the amount and speed that they are able to charge? Is there a way to confirm that the batteries are damaged or not? I’m missing over 200ah of energy seemingly so that leads me to believe that they are….
Thanks!
