WebAug 9, 2012 · If so you don't have 140 amps of solar, it would be 100 amps. Each M215 inverter outputs 208 volt 1-phase power. Easiest way would be to tap off the ct cabinet ahead of the main breaker, but after the ct's with a 100 amp fused disconnect. Then you don't need to apply the 120% rule and you fall under NEC 705.12 (A) and not 705.12 (D) (2) WebAvoiding Back Feed in PV Repowering and Solar + Storage. When operating a PV plant, the goal is to of course get as much solar energy onto the grid or the connected load. In a PV only installation, this is generally a straight forward process. The sun hits the solar panels which in turn push energy through conduit through an inverter.
