Hello. New to the forum. I’d appreciate some advice to double check calculations. I have #3 150w panels with the following parameters for each panel…
Pmax 150W
Vmp 18.0V
Imp 8.34A
Voc 21.6V
Isc 9.19A
I have a 12v 100Ah battery and I want to appropriately size a controller, wires etc…. I would like to use the 3 panels with 2 in Series and 1 Parallel. How do we calculate the voltage and current? The temps in our build area can drop to minus 40F in the winter for a few days and the battery I’m using is made by Sunrich energy and is self-heating. 12v 100Ah. It is being used to power 245wh pond aeration pump for 6-8 hours maximum per day year round.
Thank you kindly for your help!
