Generac PWRcell can be disabled if:
•
Disabled by a user.
•
A safety shutdown was performed.
•
Generac PWRcell reached a critically low state of
charge and no REbus voltage was present
•
No grid power was available during commissioning.
NOTE: To avoid the need for a manual enable, keep
Generac PWRcell enabled, connected to REbus, and
with Battery Disconnect ON.
To perform a Manual Enable:
1. Turn Battery Disconnect (A) ON.
2. If the unit is disabled, LED (B) will light red for 3
seconds.
3. While the LED is still red, turn Battery Disconnect
OFF.
4. Perform steps 1-3 three times in total.
5. Turn Battery Disconnect ON for a fourth time.
Generac PWRcell is now enabled. If the battery has
