|
| AC Current Sensor Fault
Start by disconnecting the PV+ and PV- connections, as well as the battery, and then carefully reconnect them. If this does not return the inverter to its normal state, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| Over Load in EPS Mode.
Turn off any high power devices connected to the system and press the "ESC" button to restart the inverter. If the inverter does not return to its normal state, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| Over Current in EPS Mode.
Start by ensuring that the load power is within the EPS power range. If the load power is within the recommended range, check to see if any nonlinear loads are connected to the EPS. If any nonlinear loads are present, remove them and check if the inverter can recover. If the inverter does not return to its normal state after performing these steps, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| DCI Device Fault
Try disconnecting the PV+ and PV- connections, as well as the battery, and then carefully reconnecting them. If this does not return the inverter to its normal state, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| EPS Relay Fault
Try disconnecting the PV+, PV-, grid, and battery connections, and then carefully reconnecting them. If this does not return the inverter to its normal state, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| Over current Fault.
First, wait for a while to see if it returns to its normal state. If it doesn't, try disconnecting the PV+ and PV- connections, as well as the battery, and then carefully reconnecting them. If the inverter still doesn't return to its normal state, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| Grid is Lost.
If there is an interruption in the utility power, your solar power system will automatically reconnect once the utility power returns to normal. However, if your inverter fails to return to its normal state after the utility power has been restored, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| Grid Voltage Out of Range
Once the utility power has been restored to normal, your solar power system will automatically reconnect. However, if your inverter fails to return to its normal state even after the utility power has been restored, it's advisable to contact a local solar power expert for further assistance in analyzing and resolving the issue. |
| Grid Voltage out of range
Your solar power system will automatically reconnect to the utility power once it returns to normal. However, if your inverter fails to return to its normal state even after the utility power has been restored, it's recommended that you seek the assistance of a local solar power expert for further analysis and resolution of the issue. |
| The Grid is Not Good.
Once the utility power returns to normal, your solar power system will automatically reconnect. However, if your inverter fails to return to its normal state, it's important to contact a local solar power expert for further assistance in diagnosing and resolving the issue. |
| Bus Voltage out of Normal Range.
Start by disconnecting PV+ , PV- and battery, and then reconnect them. Next, check if the PV input is within the range of the inverter. If your inverter fails to return to its normal state, it's important to contact a local solar power expert for further assistance in diagnosing and resolving the issue. |
| The grid’s voltage is out of range for the last 5 Minutes.
If the grid is restored, the system will return to its normal state. However, if the inverter still does not return to its normal state, it is recommended to contact your local solar power expert for further assistance. |
| Inverter over current protection fault
• Allow some time to pass and check if the inverter returns to its normal state. • If the inverter doesn't go back to normal, please contact your local solar power expert for further assistance. |
| PV Voltage Fault
Verify the PV voltage output and ensure it is within the expected range. If the inverter fails to return to its regular operation state, it is advisable to seek assistance from a qualified solar power professional in your area. |
| The grid’s Voltage is out of range for the last 10 minutes.
Once the grid is restored, the system should return to its normal operation. However, if the inverter fails to resume its regular operation state, it is recommended to seek assistance from a certified solar power expert in your local area. |
| Isolation Fault
Inspect the inverter connection and ensure it is properly secured. If the inverter fails to return to its normal operating state, it is recommended to seek assistance from a certified solar power expert in your local area. |
| Temperature over the limitation
Ensure the fan is operating normally and that the environmental temperature is within the acceptable range. If the inverter fails to return to its regular operation state, it is advisable to seek assistance from a qualified solar power professional in your area |
