Look at the Magnu 4448AE inverters, they have a great charger that draws less
incoming ac that any of the other chargers that I have tried. Seems that 2 of
the 4448 inverters will each put about 60 amps DC into a battery bank with only
17 amps in @ 240 volts or 34 amps ac @ 120 volts. <br>

is that we have to open the voltage window too wide to let the grid in at all,
and thus unacceptable to the electronics.) So, we DO NOT connect the AC
IN to the inverters. In other words, the FX units become inverters only,
and never pass AC current from the grid to the loads. (This is what we
are calling "no contact" system – similar to a double conversion UPS
