[RE-wrenches] High Power Split phase inverter/chargers

[Jeff Clearwater]

The Sol-Ark manual indicates 240 Volt stacking to 8 units (9 units for 
208V).  They list the "12KW" off-grid output as 8 KWs each.  So 64 KWs.

anybody stacked a signficant number of them yet?

Looking forward to hearing feedback from experienced installers.

Best,

Jeff
