Slide 8: Grid Outage Behavior
Grid Outage Behavior AC PV with PWRcell When in Island Mode, PWRcell will generate If power cannot be exported to the grid… a simulated grid to maintain power to home loads. This will allow AC PV load-side of the ATS to maintain operation. Since grid export is not possible, when the AC PV has the po
Slide 9: Management Criteria
Management Criteria AC PV with PWRcell • A new inverter setpoint – ACPVPower – will allow PWRcell to determine when AC-coupled PV production should be managed OFF, and when it can be safely allowed to resume operation. • ACPVPower may be set between 0 and 7.6kW (0 indicates no AC-coupled PV is conne
Slide 10: Cutoff Thresholds
Cutoff Thresholds AC PV with PWRcell High SoC; Low BACP • Battery Available Charging Power (BACP) is based on the ACPVPower Setting and the State of BACP is lower than Charge (SoC) of the Battery. ACPVPower Setting • As Battery State-of-Charge (SoC) increases, AC PV is BACP will decrease. managed OF
