[RE-wrenches] Generator brains

This is what I did at my house.  There's large conductors going to the house for the generator output and small conductors coming back from the main load center to power the charger and electronics.  I live off the grid and the load isn't noticeable.

Thanks,
Will

Bill,
This is the new reality, for better or worse. Most gennies are primarily built for residential backup and use the grid AC to maintain readiness. 

In a new installation, running one more conductor to carry system AC for the generator, often no larger than 14awg, with the output and signal bundle, makes the gennie's tare just another base load.

I would like to think the PV would take some of the load off the AC connection to the main off-grid system, with no conflicts.
