Backup battery charger
I want to setup a back up battery charger system. I have a 12k propane generator hooked up to dual xantrex 4048 xw. All setup for 240 charging. I'm off grid. I would want to use one or two eu2000 generators since I already have them. I have two with the crossover cable, but if possible I would like to use only one. Although one may not provide enough charge rate. The battery is ~1000ah forklift battery, The idea here is strictly backup in case the propane genset dies.
I'm thinking an additional charger rather than having a switch to toggle generator inputs to the xw due to the propane being wired for 240 and the hondas only 120. Seems simpler to just use an additional charger.
Anyway, any recommendations for charging hardware? Do any of the chargers like iota allow you to throttle back charging output in order to limit load on the gen sets? Seems like most are meant to be used for on grid applications where charging source comes from the grid.
