General Information
System Recovery During a Utility Grid Outage
If during a utility service interruption, the PWRcell system stops powering backup loads, refer to
Table 2-5
.
NOTE: Please read sections on Island Mode , Sleep Mode , and Power Search for complete understanding of system
performance during a utility grid outage.
Table 2-5. System Recovery
Problem Possible Cause Solution
During an extended grid
outage the system turned
off.
The battery may have dis -
charged to its Minimum
State of Charge (SoC) and
gone to sleep. See
Island
Mode
.
Wait until grid power returns or until the sun rises. In an extended
outage, the battery will perform a power search every hour for four
minutes (default). Once solar power is detected during a power
search, the battery will keep the system awake and begin charging
/ powering loads. See
Power Search
. Reference

Utility grid power went out;
backup loads are not
being powered.
This could be due to an
overload condition where
having too many house
loads on at one time has
caused the inverter to pro -
tect itself by purposely black -
ing out.
Inverter LED will be alternating on a 3 second interval - blinking
green, then solid red. The home screen and the inverter device
page will show “Islanded” or “Islanding” alternating with “Island
Overload.”
Reduce house loads to recover from this condition.
The battery may not have
been properly connected or
fully commissioned prior to
the outage. Reference the
Battery Status LED
for
confirmation of battery state/
functionality.
Contact your authorized Generac PWRcell dealer for service.
Utility grid power went out;
backup loads were not
powered; red shutdown
button was pressed on the
inverter.
The system may have expe -
rienced an overload condi -
tion from having too many
house loads on at one time.
The inverter will purposely
blackout to protect itself if
such a condition occurs.
If the red shutdown button was pressed, or the battery was dis -
abled in Island Mode and the system has shut off, reference
Sys -
tem Blackstart
to manually enable the battery and restart the
system.
