Description
Recommended Action: No action is required unless the condition
persists.
Description: The average current to the grid is too low for the
configured grid profile.
When the microinverter is operating normally, no DC current is
injected into the grid. If the DC current is too low (negative), this
may indicate an issue with the microinverter.
If the condition persists: contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/support/.
Description: The Envoy has completed a change to the grid profile
for the microinverters. No action is required.
Description: The Envoy has detected and is now associated to a
new microinverter.
No action is required.
Recommended Action: Occasional instances of this error may be
ignored. Communications will likely recover on the next reporting
cycle.
If communications do not recover immediately, make sure that the
Envoy is plugged in very near to the load center. Also, if other
devices are sharing the receptacle with the Envoy, remove those
devices to improve communication signal strength.
If the Enphase Envoy was recently relocated or if new devices or
appliances were added to the circuit, it is possible that the new
situation is not suitable for power line communication. The Envoy
may need to be relocated to improve signal strength, and reduce
interfering noise on the power lines.
To determine the quality of the Envoy's location for communication,
please run a Communication Check by holding down the Envoy's
menu button until the LCD display reads "Enable Communication
Check" and then release the menu button. The Envoy will then
broadcast a signal to the microinverters and within 5 minutes a
"Comm Level" indication of 0 to 5 bars will display on the Envoy LCD
display. The Envoy requires a minimum of 3 bars to communicate
effectively with the microinverters.
Description: The Envoy reporting this condition is unable to
communicate with the microinverters over the power lines.
If the condition persists: See Power Line Communication
Troubleshooting on page 27, or contact your installer, or refer to the
Troubleshooting Guide at http://www.enphase.com/support/.
Description: The attempt to change the grid profile for the
microinverters has failed after five tries. The Envoy will continue to
attempt to change the grid profile. No action is required.
