Agreed. We're all offering ways to work
as well as possible with the wrong generator choice for this
application.

Sounds
like they need a 20 Kw Kohler. Hot Tub in the future? They'll
love their Kohler. The Generac is just way too small to even
consider IMHO.

Gen support would be ideal but this inverter setup will be a
quad pack of Magnum 4024PAE (120/240 split; 16kW). Their New MSH
inverter is single phase only and can not be stacked.
While disabling load(s) is the antithesis of the desired
outcome, I'll review this possibility further.
Using a separate charger could work but it would need to be
about 200A @ 32V which would add quite a bit of cost and be hard
to sell since the Magnum inverters already have 4 high quality
charges included.
A larger generator might be necessary if the customer won't
agree to load shedding. Their plans are to expand the loads over
time, operate a business, install a hot tube and more. Of course
I have pushed the concept that conservation is paramount. The PV
array and inverters are being oversized now for the future
growth.
My ideal solution...Since Magnum inverters monitor the AC input
and control it based on quality of power, it seems to me that
there could be a setting for disconnecting the AC input if loads
exceed a setpoint. Change in control software would be great.
Thank you,
Larry
