Description
DCResistanceLoPowerOff
Recommended Action: Clear this error via Enlighten’s Current Issues page. Note
that the condition will not clear after sensor reset if the cause of the failure is still
present. If the condition persists, contact your installer.
Description: An IR sensor in the microinverter measures the resistance between
the positive and negative PV inputs to ground. If either resistance drops below a
threshold, the microinverter stops power production and raises this condition. This
may indicate defective module insulation, defective wiring or connectors, moisture
ingress, etc. Although the cause may be temporary, this microinverter condition
persists until the sensor is manually reset.
If the condition persists: If the event persists after clearing the condition, contact
your installer.
For further assistance, contact Enphase Energy customer support at

DcVoltageTooHigh
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
enphase.com/support.
DcVoltageTooLow
Recommended Action: This is usually a normal condition during hours of low light
and at dawn and dusk. No action is required.
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
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.
