[RE-wrenches] 2nd VFX3648 added to double charger rate

[Kirk Herander]

And can't you just wire up the new inverter as a "dumb" battery charger
only? If you don't need to double KW to loads, don't try to stack it, or
connect it to the hub. Just cable it to the batteries, and wire the genny
to it's AC in. NO AC out wiring. When genny is running, it should charge
fine. A last resort.
