In general, both.
This ag opportunity is to load shift out of TOU zone, but wants resiliency too.

Wes – Indeed, max Sunny Island 240VAC cluster is 4 units, so 23kW max BATTERY
power.
Limit of roughly 27kW of PV (4x 120V x 56A relay limit = 26,880W) with that
cluster if grid-tied with backfeed, so around 50kW max daytime load offset per
cluster. That may help if peak loads are always daytime?
Are you trying to take these systems off-grid, or just reduce peak load?

Hi Jeff,
I think the biggest split phase sunny island system is 4 units, so that's 24KW.
What do you do for larger systems? Segment the loads? Not always very
practical.
This latest opportunity is for an agricultural building that peaks at 75KW.

All of my SMA Sunny Island Sunny Boy AC coupled systems greater than 12 KW have
worked flawlessly and delivered reliable power and good monitoring for years.
Less excited about my Schneider and Outback systems due to callbacks and
hassles. a bit more expensive but worth it IMHO.
Hope that helps!

Hi friends,
I keep running across opportunities with 50KW-300KW peak load requirements, on
split phase services. Big homes, agriculture etc.
Outback, Schneider, SMA can all gang/stack into the 30-50KW range, but north of
there, I am not finding many (any?) options?
Just found Aims Power 50 KW split phase unit with claims of higher power
offerings by special order. Even the 50KW unit is $20K, so quite spendy. Any
experience with these guys?
