Need a recommendation for 24 volt charger that will run off a 3500 watt gasoline generator.

Arrived at the off grid house today after working 2 weeks in the city, over a foot of snow on my panels and my 8 12 volt AGM 110 amp/hr battery bank was low and my samlex inverter in error condition due to low voltage. Voltage was 24.3 volts so not likely detrimental to the batteries.

I have never been away so long and never have had to deal with low battery like this - over cast sky for days, snow on the panels etc etc… outback said we only made about 600 watts of power today. (Snow was cleared yesterday)

I have had a noco genius 7200 something or other new in box for years, powered up the gent and plucked er all in… 24 hours later I’m only 50% charged and just read the manual, its only like 3.5 amps ! Yikes.. think I’d like something in the range of 60 amps, something that will run off a honda 3500 watt inverter generator.

Is there such a beast ?

What you're looking for is a wheeled battery charger that a big rig shop would use. 60 and 40 amp chargr, mechanical timer.

What you want is an ac charger like samlex has. Not on wheels but actually made for deep cycle batteries. Samlex model SEC-2440UL is there 40 amp 24volt charger or Iota engineering makes one for about half the price. But I believe you have to buy an iq controller to use the full range of functions to properly charge your bank. I would go with the samlex.
