<DIV>I guess this assumes the charger is 100% efficient?</DIV>
<DIV> </DIV>
<DIV>Has anyone measured the current draw from the 12v source while the
charger is putting out x amps?</DIV>
<DIV> </DIV>
<DIV>From what I gather, the Iota will be the limiting factor. I believe the
Iota will go into a constant-current mode once the 55 amp rating is reached,
IOW, the voltage will drop. This will limit the power drawn from the
generator.</DIV>
<DIV> </DIV>
<DIV>Another way to approach this is to use a small deep-cycle battery
connected to the Iota output. The battery will not have to carry the full load
of the chargers, just the excess that the Iota might not be able to supply.
When one of the chargers is done, the deep cycle battery is charged back by
the Iota.</DIV>
