Hi Wrenches, How does one determine how much imbalance can be tolerated on a 3 phase system?
I'd like to feed 2 SMA SB5000s at 277 VAC into a 480 VAC panel instead of 1 13 KW Solectria at 480VAC as the PV system is only 9500 Watts STC. The main on the backfed service panel is 600 A. But I'm not that sure of the loads as it's new construction and hasn't been characterized.
What are the appropriate calcs to do here? Thanks!
