180 amperes bulk charge rate is not inappropriate. But the Iota's optional "smart" 14.2 volt voltage absorbsion limit is .6 of a volt off the mark for minimizing generator run time while maintaining a safe charging voltage level IMHO. 14.8 volts can be used in a time limited meaning definitely user monitored charging protocol to render a significant reduction in generator run time each recharging cycle. The 14.8 volt at absorbsion time limit has to be established by the user custom tailored for his bank.
Advantage? About 30 to 40 percent LESS generator run time to fill batteries from 50% to 95%. Subsequent recharges can be done using a spring wound timer.
The quandary comes when a supplemental charger is used and the converter leans on a shovel and squeals it is simply maintaining it's advertised 14.2 volt bulk charge setting.
The specifics are obvious: The amount of amperage differential between 14.2 and 14.8 volts charging.
I believe BFL 13 can chime in with a valuable second opinion on this subject.
