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.

We did a test installation in northern British Columbia with 28kW of
PV and GT5 inverters selling to a 90kW Genny system in a remote
off-grid community. So far we have just stuck to the normal 1741
islanding settings, and the system has been working smoothly. The PV
was basically sized so that it would not exceed the lowest mid-day
load on the small grid, and there was already an automatic dump load
in the system to ensure the diesels never became completely unloaded.
So far the system has been working very well, with good fuel saving
for the community. You can read more about it here.
