I think I'm missing some details, because I'm having trouble reconciling 900AH with 8x250AH @ 24V. What voltage are the individual batteries at? Assuming you've got eight 6V 250AH batteries, that's about 12kWh capacity (6kWh @ 50% DOD). Maybe that would run your 1230 watt load for about 4-5 hours. Anyway, you'd want to check to see what charge rate the battery manufacturer recommends. If they're lead acid batteries, I think C/10 is usually a reasonable rate. First figure out your battery capacity (Watts = Amps * Volts), then divide by the charge rate. For example, if you've got a 12kWh battery bank, a C/10 charge rate would be 1.2kW. That would be 50 amps at 24V. It might be worth checking the actual printer load with a watt hour meter, too. If there are times the printer is idle, the overall consumption may be lower. Hi Allan.

I have a 900AH battery bank consisting of 8x250AH batteries on a 24v system. I intend to run a printer with a 1230watts rating for 10hrs as backup. this system will be connected to utility 220 v power.what is the best charger size to use on this batt bank. Thanx Hi.
