a locally purchased battery charger
, and since the output of the charger
is 12 VDC, wouldn't that make it possible to charge my house bank? Then, by turning on my inverter
(which would not be connected to shorepower, whatsoever) I could then transform the housebank 12 volt power into 110 VAC/60 cycles for my own consumption
using my boat's AC outlets. I am talking about 15 amps of AC, not powering an electric
heater or waterheater.
not really miscommunication. I just don't know what you have on the boat. if all you are running is a few small things on a few plugs. then yes. if you have a lot of ac stuff on the boat, then it's not so easy. because on most boats not everything gets powered by the inverter
, and those things wouldn't work unless you started the genny.
if you had a lot of ac stuff. you'd need a really big charger. if you are pulling a constant 15a off your inverter you are pulling 150 amps off your battery
. which means you would need a really big charger to plug
into the dock
but if you just have small things, or big things for short time (microwave etc) then a smaller charger would work.
