Using a generator to power an onboard charger.



My uncle has an island on Rainy Lake that we stay on for a week each summer that has no power.

I have an 80# Terrova with I-Pilot and an 80# Vantage wired to a pair of Group 27 AGMs.

I use a Minn Kota 230 (2 banks x 15amps) that says it draws 7A @ 120 VAC 60 HZ.

Can someone convert that draw to watts for me? Is it as simple as 7A = 700 watts? Pardon my ignorance.

Will a Honda EU1000i get the job done? Or do I invest in a second set of AGMs?

So to spin off that same topic since I'm in the same situation with charging batteries while camping on Rainy, I'm wondering if I should get one of those switches that allows my two deep cycles to connect to my starting battery.

The purpose of the switch is to have the ability to use your deeps to start your motor if your starting battery goes dead but I'm thinking more of how much of a charge I would get to my deep cycles if I'm trolling with my t8 kicker or running my yamaha 225 vmax hpdi.

Is there enough juice coming off the alternators for either of those two motors to not only recharge my starting battery but give a boost to my two deep cycles as well?

Check the output sinewave on your genarator. I read some where in my owners man that said the onboard charger can only take one kind of wave lenght. Do not want to burn something up out in the middle of no where!
