How do you BIG stereo guys power them?

[Nick Hughes]

I like the solar charger idea. Over a week that should add a bunch.

I don't use a ACR, anything more than 1 battery will stress the stators esp... the larger AH batteries. I am have 2 house batteries & 1 starter battery, I don't charge my 2 house batteries when I am on the water, I leave it up to my Dual Pro PS3 charger to charge my house system when back on shore, I use serious juice, JL 7.7's front, 8.8's rear, Wetsounds Rev10's tower, 2 JL HD 600/4 amps on the house system, plus a 120 volt 1600 watt inverter (power a 120 pump for tubes) , the rest is on the starter battery including my LED's since the amps will dim the LED's when I start bumping which is about a total of 80 amp pull at full power.

What batteries are looking at? Optima blue top 31's are about 75 amp hours, so 3 of them will get you 225ah

also I don't think your running your sound system at full power 100% of the time, I am sure you tone it down when chillin so you not using max power all the time.

Do you think a power inverter would be able to power an on-board battery charger like the Noco GENM2 and work well with no issues?
I was wondering if I can charge the batteries while out on the water ....... Inverter on > charger on > batteries charging.

Are you asking if you can use a inverter from DC to AC, then try and charger the batteries with the NOCO while on the water? simple answer is NO, inverters use massive DC power and output lots of heat, it will be a loss to convert from DC -> AC, then AC-> back to DC. You'll drain your batteries faster, don't forget batteries absorb about 10+/- amps per hour, you can drain them much faster than that.

if you only have 1 house battery & 1 starter battery, then a ACR is recommended. The stators will wear out if you try and charge more than 1 battery at a time, limits of the system. I wish Yamaha had full size alternators, but they require a belt system, well most do.

I highly recommend Dual Pro chargers, Noco's seem to disappoint when higher power is needed.

Ohhh I see..... got it. Yeah, I didn't know Yamahas didn't have alternators until recently ...... first time dealing with stators.

Um...use a generator. Honda makes nice little quiet generators that will do the trick.
