Description
Recommended Action: This condition should correct itself. No
action is required.
Description: The microinverter reports that the AC voltage coming
from the utility is either too low or too high as specified by applicable
regional standards.
When the microinverter detects a voltage out of range condition, it
must remain offline until the utility has been within acceptable limits
continuously for a short period of time (several minutes, varies by
region). If, during those several minutes the utility again exceeds or
falls short of acceptable limits, the timer must restart and the
microinverter may not begin producing power for an additional short
period following the last out-of-bounds condition.
If the condition persists: contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/support/.
Description: The Envoy has started a change to the grid profile for
the microinverters. This process may take a few minutes. No action is
required.
xx = grid profile name
yy = Regional specification name.
Description: The microinverter is not producing power due to a
software problem.
For assistance, contact Enphase Energy customer support.
Recommended Action: No action is required; it will automatically
resume normal operation momentarily.
Description: The microinverter was reset, either following a
successful software download or by user command.
Description: The Envoy has received a control request made via the
Envoy interface (Administration > Device Conditions and Controls
page) or via Enlighten.
This uncommon condition will occur only during isolated
troubleshooting procedures by Enphase personnel. No action is
required.
Recommended Action: This condition should correct itself. No
action is required.
Description: This rare condition occurs if the microinverter reports
an internal temperature that exceeds its rated range. It reacts by
producing less power to reduce internal temperature. Once the
internal temperature of the microinverter diminishes, it will resume
full power production and this error message will clear.
If the condition persists: contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/support/.
