Grid Vtg. Fault |
The grid voltage has exceeded the
permitted range according to local
grid regulations.
Following causes might lead to
this error:
• Grid voltage is too high or too low at the point of common coupling to the inverter.
• Grid impedance at the terminal of the inverter is too high.
For safety consideration, the
inverter will disconnect itself from
the grid for a short period of time,
and it will reconnect to the grid
automatically after a short period
of time if the grid voltage is back
to the permitted range. |
• Check the grid voltage.
• Check the grid connection
of the inverter.
If the grid voltage exceeds the permitted range because of local grid conditions, please ask the utility operator if the voltage can be adjusted at the feed-in point or if changes in the values of the monitored operational limits are possible.
If the grid voltage that checked is within the permitted range, yet this error is still showing in the LCD screen, please contact Macsolar Serviceline. |

Grid Vtg.10min Fault |
The average grid voltage over 10 minutes has been outside the permitted range according to local grid regulations.
Following causes might lead to this error:
• Grid voltage is too high at the point of common coupling to the inverter.
• Grid impedance at the terminal of the inverter is too high.
For safety consideration, the inverter will disconnect itself from the grid for a short period of time, and it will reconnect to the grid automatically after a short period
of time if the grid voltage is back
to the permitted range. |
• Check the grid voltage.
• Check the grid connection
of the inverter.
If the grid voltage exceeds the permitted range because of local grid conditions, please ask the utility operator if the voltage can be adjusted at the feed-in point or if changes in the values of the monitored operational possible.
If the grid voltage that checked is within the permitted range, yet this error is still showing in the LCD screen, please contact
Serviceline. |
| 2 |
Fac Fault |
The grid frequency has left the
permitted range.
For safety consideration, the
inverter will disconnect itself from
the grid for a short period of time,
and it will reconnect to the grid
automatically after a short period
of time if the grid frequency is
back to the permitted range. |
• Within safety scope, check
the grid frequency and observe how often major deviations occur.
If there are repeated frequency turbulences which lead to this error, please ask the utility operator if modification of the operating parameter is possible.
If this error is not solvable, please contact Macsolar Serviceline. |
| 3 |
Utility Loss |
The inverter has detected an error
in the cabling and cannot connect
to the grid.
Following causes might lead to
this error:
• Grid connection installation
failure.
• Cabling failure.
• Incorrect country setting. |
• Check AC installation.
• Check grid connection.
• Check if the country setting
is correct:
– Via LCD screen (please
refer to chapter 7.2
“Configuration”).
– Via the remote
communication: setting
Parameter “Country”.
If this error is not solvable, please
contact Macsolar Serviceline. |

paralleling connected with the
string is too high.
Following causes might lead to
this error:

inverter will shutdown itself. |
• Please
disconnect the inverter
from the PV strings (see
chapter 6.5 “DC side
Disconnection”) or else
the inverter might be
damaged.

the strings for adherence to
the maximum input voltage
of the inverter, before you
reconnect the inverter to
the PV strings. |
| 5 |
GFCI Fault |
The inverter has detected a ground
fault in the PV generator. |
• The installer of the PV
generator must solve the
ground faults before you
re-connect the strings.
If this error is not solvable, please
contact Macsolar Serviceline. |
| 6 |
Over-temperature |
The delivered power of the
inverter was reduced below rated
power because of abnormal
temperature within 0.5s.
Following causes might lead to
this error:
• At least one or more of the
thermally monitored
varistors are defective.
• Overheating inside.
• Not sufficient ventilation. |
If this event occurs often:
• Please ensure sufficient
ventilation.
• Check the varistors.
If this error is not solvable, please
contact Macsolar Serviceline. |
| 7 |
Varistor Fault |
At least one of the varistors from
the DC or AC side is defected.
Following causes might lead to
this error:
• Varistor is bust due to contact Macsolar Serviceline. over-voltage protection. |
If this event occurs:
Please check the varistors
as chapter 5.6 “Check
Varistors”.
If this error is not solvable, please |
| 8 |
PV-Overvoltage |
The DC input voltage which
connects to the inverter is too high.
Following causes might lead to
this error:
• The open-circuit voltage of
the PV generator is higher
than the maximum DC
input voltage of the
inverter.
• Sudden DC surge.
• Junction temperature of
solar panel too low. |
• Please immediately
disconnect the inverter
from the PV strings (see
chapter 6.5 “DC side
Disconnection”) or else
the inverter might be
damaged.
Check the DC voltage of
the strings for adherence to the
maximum input voltage of the
inverter, before you reconnect
the inverter to the PV strings. |

For an Eversolar Eversol Solar Inverter, performing a proper shutdown procedure can already fix some minor issues. But there are some errors that involve doing some specific steps. Gold Coast Power Solutions have put together a list of faults, displays and possible actions in case you experience any of the problems below.
The full details are available in the Eversolar Eversol Solar Inverter manual’s Troubleshooting section. If the issue continues after following the actions above, check if your Eversolar Eversol Solar Inverter is still within the 5-year warranty period so the issue can be covered. However, if the inverter is outside warranty, we suggest you contact a professional solar power expert. If you’re in the Gold Coast or Brisbane area contact Gold Coast Power Solutions here so our team can provide you with further assistance.
