Solar Trickle charging
Sorry not sure where to ask. Have 2020 3930FB.
I'm wondering if there is any documentation on how many watts of solar is needed to trickle charge batteries. I have 2 - 6V 225 amp hour interstate deep cycle batteries, controller is 100W. Partly the reason I ask is I ALSO have a CalAmp GPS (for theft) unit that I would like to leave powered during winter storage months. I live in CO so mostly sunny. I currently have a 240W solar panel but NEVER, even on hot days, have i seen over 180 watts generated. Usually around 80-120W which concerns me as well.
