Recommended Action: Ask your installer to check that the PV module and
microinverter are compatible. It may be that the PV module generates a higher
voltage than is recommended for the microinverter. The Enphase M250 and M215
are compatible with most 60-cell modules. The M190 and D380 are compatible
with many 60- and 72-cell modules.
Description: The microinverter reports that DC input voltage from the PV module
is too high.
If the condition persists: If the PV module is compatible and the condition
persists, contact your installer or refer to the Troubleshooting Guide at
http://www.enphase.com/support.
Recommended Action: This is usually a normal condition during hours of low light
and at dawn and dusk.
Description: The microinverter reports that DC input voltage from the PV module
is too low. If this condition does not clear during hours of full daylight, the
microinverters may be heavily shaded or covered by snow.
If the condition persists: If this event occurs during full daylight or if the condition
persists, contact your installer or refer to the Troubleshooting Guide at
http://www.enphase.com/support.
If this event occurs and clears daily or often during hours of full daylight, check that
the PV module and microinverter are compatible. The M215 and M250 are
compatible with most 60-cell modules.
Description: The Envoy has started a software upgrade to the indicated
microinverter.
Recommended Action: This process may take a few minutes. No action is
required.

microinverter.

Description: The Envoy was unable to successfully deliver a software upgrade to
a microinverter.
Recommended Action: No action is required; the Envoy will repeat the attempt.

This condition does not affect your system’s ability to produce power. When the
connection is restored, the Envoy will catch up with the transmission of any/all
energy data it has stored.

Failure or if it never moves beyond the Initialization stage, contact your installer or
refer to the Troubleshooting Guide at http://www.enphase.com/support.
