I was thinking of solar etc. just last night.
If I were to set up solar, I'd install a cig lighter socket to accept
input from either a battery charger or solar. Each charge source would
be wired with a male cig plug. Not sure if a standard cig socket would
handle higher input amps. Maybe other type of socket? (though cig
socket would be handy as it would obviously provide a standard
interface for 12V appliances)
One socket = only input from either panel or charger, but not both at
once. As for alternator.....
Isn't the electronic isolater set up so that if alt input "seen" and
sent to aux batt. then other sources are blocked?
