Recommended Action
: In most cases no action is required. If there is a
power outage in your area and the system has stopped production, solar
production will resume when the utility restores power to your area. Verify
that the circuit breaker(s) for the PV array are ON at the load center. If all
breaker(s) are on, the condition should clear itself.
Description
: The microinverter detects no power coming from the local
Utility.
Enphase microinverters are “utility interactive” and require a connection to
the utility.
If the condition persists
: If Grid Gone events persist, contact your installer
or refer to the Troubleshooting Guide at
http://www.enphase.com/support/.
Grid Instability Grid Instability
Description
: The microinverter is not producing power due to one or more
of these conditions: AC Frequency Out Of Range, AC Voltage Out Of
Range, or Grid Gone. Note that Grid Instability will remain for about five
minutes after the underlying conditions clear. No power is produced
during this time.
No action is required unless the condition persists. If it persists, contact
Enphase Energy customer support.
