Disabling the TOU Scheduler in Anticipation of a 
Grid Outage

In the event of an impending storm and potential outage, 
top off the battery by disabling the scheduler and switch-
ing the operational mode to any of the backup modes. 
To disable the TOU Scheduler:

1.

Navigate to the Generac Beacon device page and 
disable the scheduler. See 

Disabling Generac 

Beacon

 for more information.

2.

Navigate to the system home page and change the 
operational mode to a backup-only mode, such as 
Priority Backup or Clean Backup. See the Generac 
PWRcell Inverter Owner’s Manual for more infor-
mation on operational modes. 

3.

Once the emergency has passed, re-enable the 
scheduler. See 

Enabling Generac Beacon

 for 

more information.

NOTE: 

If Priority Backup mode is not listed with the other 

operational modes, the system installer may have 
removed the mode to comply with utility rules. Some utili-
ties do not permit grid battery charging.
