[RE-wrenches] 3 phase battery inverters

[Drake]

Hi Jay,

I had to deal with this once on a Trace SW 
system. The cheapest option turned out to be to 
just adding another inverter, not synchronized, 
on the third leg of the generator.

All loads were 120/240, so no need for 208. 
Commercial battery chargers were way expensive. 
The non synchronized inverter charged batteries 
just fine, and was used with a separate panel to 
feed a few tough loads that could have caused the 
lights to dim on surge. The three phase generator 
windings were reasonably well balanced with this setup.
