This boat isn't hooked up to shore power at all. The power comes from a 17 watt solar
panel and a worn-out 800 or so watt wind-turbine. The wind-turbine doesn't have to be going for me to feel anything, but I'll double-check that. I never run the engine
to charge the batteries.

I'm luck if the wind-generator can get it past 12.3 in a full day of charging
. Sometimes the the solar panel can bring it to 12.3 V DC in a day.
I try not to let it go below 12.2 V DC
I usually charge my laptop
battery at least once a day, so that might be 100 watts for an hour with the inverter
is always on anchor-alarm, but it's not supposed to even draw 1/4 watt and the backlight setting of the GPS
is always dim. It's a Lowarance Mar-4 grey-screen.
>I don't know US systems but I believe some US appliances
Yes, that's true, but not on this boat.
> Does air conditioning
typically do that? Do larger boats use two shore power
leads and could the reverse polarity breaker be intended to utilise two phases in that way?
I believe the Air conditioner only works w/ 120V AC from shore-power, so I don't use the Air conditioner. My boat does have 2 a/c shorepower outlets to hook up to, but it's always unhooked. I never use shorepower a/c. Only my little 400 watt inverter
to charge the laptop
about 1 or 2 hours a day.
>Does your boat have two shore power
>Or is the reverse polarity breaker just to identify/disconnect a wrongly-wired dock
Wow! fascinating knowledge. It could be. I'll ask the PO.
