System Operation

Automatic Generator Override Conditions

When configured for generator integration, the PWRcell Inverter looks for reserve power. If load exceeds the reserve
capacity (typically 9 kW) of the PWRcell Battery, the inverter will set a 30-minute timer allowing the generator to turn-on
and cover the load until the timer runs out.
The following is a list of conditions for the PWRcell Inverter to allow an integrated generator to turn ON or OFF during a
grid outage.
The PWRcell Inverter will allow a generator to turn ON if any of these conditions are met:
Condition 1 - The Generator Manual Override = 'Turn Gen On'
Condition 2 - The Generator Manual Override = 'Auto Gen Ctrl' AND
•
Battery SoC is less than or equal to 25% OR
•
Home Load Demand exceeds PWRcell ESS Capacity
Condition 3 - The Generator Manual Override = 'Turn Gen Off' AND
Home Load Demand exceeds PWRcell ESS Capacity
The PWRcell Inverter will prompt a generator to turn OFF if any of these conditions are met:
Condition 1 - The Generator Manual Override = 'Turn Gen Off'
Condition 2 - The Generator Manual Override = 'Auto Gen Ctrl' AND
•
Battery SoC is greater than or equal to 95% AND
•
Home Load Demand is less than PWRcell ESS Capacity AND
•
Time since the generator turned ON exceeds 31 minutes
