Big alternators work wonders to regain 50% SOC to 85% SOC.
Down here where there is only 1-1/2 hours less sun during winter and a corresponding lack of latitude loss of same, solar is great -- but like many other places, leave panels in a vulnerable position and they'll learn to do the Macarena on down the highway in no time.
