[RE-wrenches] grid tie sync with big stiff genny?

[Mark Edmunds]

Hi Drake - the limit in the PV in this case was so we could not exceed
the minimum load in the subdivision, to make sure there was no back feed
to the generator.

Hi Mark,

That looks like a great installation.  Is the max that can be fed 
into a generator mini grid 15%?

Since the system was able to keep the UL 1741 settings, that means 
this setup could feed both a utility grid and a generator mini grid, 
using the system transfer switch.
