tery automatically energizes REbus and begins support-
ing REbus and protected AC loads connected to the

Battery is disabled.
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
sufficient charge, LED (B) will light green to indicate the
battery is enabled and the system will Blackstart and
resume normal operation
