The problem with a 48V 30A charger is that it will need 16.5A to 19A of 120VAC continuous. This means that all of the 2kW generators won't be powerful enough. I think that the little generators will max out around 23A through a high quality charger, 18 to 20A into the batteries will be a reliable answer.
Even attached to a 30A 120VAC shore power circuit, a 48V 50A charger is the biggest that will run, a 60A charger will overload the circuit.

> Looks like a nice hefty charger. But, you would need 4 of them to make a quad for a 48 volt bank putting at the high end of battery chargers. Finding mounting space for them may be a problem too. Nice feature is the ability to turn off the charging circuitry so you can use it as a brute force power supply. Now if we can find one that's 48 volts @ 30 amps.

Fired it up and the all four outputs went to a flashing green (battery 99-100% charged) within 30 seconds. which was to be expected since the bank had been charged up over the winter solar & wind generator and aoccasionalal Zivan. Within an hour lights went to solid green 100% charge. Will have to wait until launch when I can drain down the bank and then charge. I found an out of the way location in the cabin for mounting so I can easily see the charger status LED's. I'm pretty happy so far.
