[RE-wrenches] 24v Battery Charger 80 Amps?

[bob ellison]

Why not just use a Magnum MS inverter as a 2nd charger? That way in an
emergency there is a 2nd inverter to cover a failure and it will balance the
loads with or without the PSX 240 most of the time.

I expect the transformer and 2 little chargers cost close to the same as the
inverter and not look as good on the wall either.

Want to speed up battery charging add more inverter / chargers. You could
probably add 2- 4024 Magnums as well as the SW to that large a battery bank
and be fine, but you would want to balance that one.. 

 

Later,

Bob Ellison

You could add a PSX 240 transformer to balance the generator output and then
add the IOTAs. The PSX240 I think has 6KW output.

Wrenchsters,

 

Any recommendations on a generator fed Battery Charger for a large 24v
battery bank (1,800AH). It's an existing off grid system with one Trace
SW4024 (has a 120A battery charger). They are getting a larger generator
(14kW) to run shop tools and speed up battery charging. I want to balance
off the second leg of this new generators output with a battery charger that
puts out anywhere from 80 to 100 Amps into the 24v battery bank. 

 

I could use two Iota 24 volt 40 Amp chargers for the 80 Amp max total. 

 

Other options?
