Using PV and battery backup to reduce generator run time is a no-brainer,
and we all are familiar with that sort of stuff. But using PV to augment a
Prime Power generator is not going to work at small generator sizes for a
couple of reasons.
1) Small generators are not built to run continually.
2)
The inverter to generator ratio is entirely the designer's call and
comes into play for large generators (for residential systems as
mentioned in earlier replies, it's a bad idea).
Interconnecting in spot networks in dense urban areas has a similar
issue in that the distribution system can't h
We run into this a lot in the Caribbean. Our general rule is that it
depends on the load. If it is a constant commercial load and the PV is
about half of the load, no issue. But for residential and where PV exceeds
the lowest load, we prefer to be on the utility side of the ATS or use a
contactor o
Interconnecting the inverter output to the utility side of the transfer switch
is not necessarily an absolute rule. A knowledgeable solar EE told me a few
years back, that interconnection can be made on the load side if the inverter
kW output is small compared to the generator kW, that large kW

I always connect to the utility side of the transfer switch. Since the
transfer switch is a listed electrical enclosure it is the best option I
have used.

Wrenches,
We frequently encounter residences with backup generators. The question
that arises: how should the PV system be interconnected?
