Compatibility
A 1,500 V utility architecture with 800 V output, fifteen MPPTs and advanced grid support.
Verify phases, grid voltage, fault level, earthing, SPD and protection coordination. Do not duplicate inverter protection without a design reason.
P-03 requires an 800 Vac collector and matched step-up transformer; it must not connect directly to a 400 Vac grid.
