AC Generator Control Modes

An AC generator integrated into a PWRcell ESS can operate using one of three control modes – 'Single Transfer',
'Source Cycling', or 'Always On' – depending on the installation configuration and the home owner's usage needs.
Generator Control Mode
Single Transfer
Source Cycling
Always On
NOTE: In an outage, the inverter will prioritize solar power over generator power to charge the batteries but can use
excess generator power if needed and when available.
NOTE: If the inverter system is unable to supply adequate power to the active loads, the system will switch backup
supply to the integrated generator regardless of the selected operating mode.

AC Generator Manual Override

For PWRcell systems properly configured and set for AC Generator Integration, there are manual override settings
selectable via the inverter control panel that are used to change the active AC Generator Control Mode. These manual
override settings are explained in the table below.

NOTE: Upon restoration of grid power, the manual override command will be cleared, and the inverter will transition
back to using the AC Generator Control Mode.

In the event of a power outage, the inverter will prioritize using the ESS to power the home,
and the generator will be kept off. Once the ESS SoC goes below 25%, the inverter will
switch the home to generator power. Spare generator power will be used to charge the ESS.
The home will be powered by the generator for the remainder of the outage.
In the event of a power outage, the inverter will prioritize using the ESS to power the home,
and the generator will be kept off. Once the ESS SoC goes below 25%, the inverter will
switch the home to generator power. Spare generator power will be used to charge the ESS.
Once the ESS SoC goes above 95%, the inverter will switch the home back to ESS power,
and this cycling between ESS and generator power will repeat for the remainder of the out-
age.
In the event of a power outage, inverter will prioritize using the generator to power the home.
Spare generator power will be used to charge the ESS. The home will be powered by the
generator for the remainder of the outage.

Returns the system to operate using its AC Generator Control Mode after an override
command.
Note: Selecting 'AutoACGenCtrl' does not modify the Generator Control Mode.
Sends a command to have the system turn on the integrated Generac Home Standby Gen-
erator. Use this to override Generator Control Modes, 'Single Transfer' or 'Source Cycling.'
This will allow the ESS to charge from the generator.
Sends a command to have the system turn off the integrated Generac Home Standby Gen-
erator. Use this to override the operation of the generator and allow the PWRcell system to
support house loads.
Note: Upon selection, the generator may come back on if the battery cannot support house
loads.
