If you get a small enough (low amp instead of 55amp) charger to run on the "1000w" gen, the amps will be so low it will take forever to charge the battery bank.
Forever is a long time. 30 amps will charge one or two batteries to 90% in 2 to 4 hours.... a lot less than forever.
OP seemed to indicate 1000w gen was the preference and will put about 40 amps max into the battery. Sure you can get a PD9140 to be have a few more amps. Or a 40a portable will work fine. IMO the 30a IOTA with the higher boost voltage will be virtually just as fast.
