“That seems like such a little amount. I thought it would be more about the solar's charging rates. Like "25amps per hour" or 25ah x 4.5hrs of sunlight = 100 amps charged in 'one day.' I havnt quite gotten to that research yet...”
Rarely do 300 watt solar panels produce 300 watts. The sun must be directly overhead, the temperature must be moderate and very importantly the batteries must be willing to accept 300 watts. During bulk charging they may but during absorption they won’t. The majority of the time recharging wet batteries are in the absorption phase. Lithium is different.
