[RE-wrenches] Equipment ideas for very large residential PV and battery backup

[Mac Lewis]

Hi August,

The limitation with the Sunny Island, (if you don't go 3 phase), is a quad
stack of 6048s in a 120/240 system last I checked. I think you can double
that with your islanded Sunny Boys. The 6048 had a ridiculously high surge
rating so it can cover pretty high loads.

If you go 3 phase with the multicluster box its above 100 kW.

We have done a 64 kWh Blue Ion and it seems to work extremely well. The
Sunny Island SOC algorithm and Blue Ion SOC don't track perfectly but both
are useful.

I think you can stack 10 x 8048 Radians but AC coupling then becomes a
problem.

Good luck with this.
