Why is 20 AMPS useless. It will keep batteries charged over a long period, even 3 amps will do that.
Good evening. I think the poster you are referring to mentioned a 20 watt panel, not a 20 amp panel. 20 watt will help keep a charged battery charged. It is more of a maintenance charger, not suitable for robust charging.
