SOLUTION
24
Battery type is wrong
None
1.
Set the correct battery type according to the battery installed to the system.
2.
Reboot the inverter. If the error remains, contact your installer.
Note: For third-party lithium batteries, battery type should be set as Lead Acid.
25
RCMU test fault
None
Reboot the inverter. If the error remains, contact your installer.
26
Model setting fault
None
Reboot the inverter. If the error remains, contact your installer.
27
Battery Voltage Drop
[Battery voltage dropped below 30V]
None
1.
Check the battery BMS errors and the wiring.
2.
Reboot the inverter. If the error remains, contact your installer.
28
Battery wake up fault
[The system tried to wake up the
battery but failed.]
None
1.
Turn off the inverter.
2.
Check the battery voltage.
3.
Check the battery breaker and wiring.
4.
Check the battery communication cable.
5.
Turn on the inverter. If the error remains, contact your installer.
On the Power Flows Page, the
icon will flash when there is a warning. Below are warning codes and their solutions.

SOLUTION
53
Stacking Canbus communication error
1.
Turn off the inverter.
2.
Check the canbus communication cables.
3.
Turn on the inverter. If error remains, contact your installer.
54
Power island
1.
For warning 55. If the Utility is down, wait for it to come back on.
2.
Reboot the inverter.
3.
The inverter will wait for 5 minutes before attempting to connect to the Grid.
4.
If the warning remains, contact your installer.
55
Grid is disconnected
56
Grid voltage exceeds the upper threshold
57
Grid voltage falls below the lower threshold
58
Grid frequency exceeds the upper threshold
59
Grid frequency falls below the lower threshold
61
Battery voltage is too low
[Battery voltage is less than 44V (lead-acid) or
SOC is lower than 10% (Lithium)]
Wait for the Grid or PV to charge the battery. Warning code will change to 62 once the battery
voltage is above 44V or the SOC is above 10%.
Note: Battery cannot be discharged, and system output can only come from the Grid.
62
Low battery SOC level
[The battery SOC is less than the battery
reserve]
Wait for the Grid or PV to charge the battery. Once the SOC reaches 20% above the battery
reserve, the warning will be cleared.
Notes:
If the Grid is absent, the battery can be discharged.
If the Grid is present, the battery can be discharged if SOC is above the battery reserve.
63
Battery is not detected
1.
Turn off the inverter.
2.
Make sure the battery is on.
3.
Check battery connection for any loose wiring.
4.
Turn on the inverter. If error message remains, contact your installer.
64
Inverter output OCP
1.
Inverter output current exceeds the upper threshold.
2.
Reboot the inverter. If error remains, contact your installer.
Alarm – On: 1s, Off: 1s
65
RS485 communication error
1.
Turn off the inverter and check all communication wires.
2.
Turn on the inverter. If error remains, contact your installer.
66
Output derated
[When system temperature is too high, the
output power has been derated.]
1.
Make sure the inverter is properly ventilated and the fans are free of debris.
2.
If possible, lower the load or ambient temperature.
Notes:
System output lowered to 60% when the system temperature is higher than 85°C.
System output lowered to 80% when the system temperature is higher than 80°C.
System output restored to 100% when the system temperature is lower than 70°C.
67
Off Grid Operation
Grid is present, but system is in off-grid mode via remote command.
68
Peak Shaving Over Power
Grid power usage has reached the Peak Shaving Power threshold.
69
Generator mode
The grid is not present, and the inverter is receiving power from the generator.
70
Generator Reverse Feed
Power is feeding back to the generator. If the inverter is setup to have remote control over the
generator, the inverter will turn off the generator.
71
Battery voltage Inconsistent
Battery voltage measured by the inverter is not consistent with the BMS value.
