To Next PageTo Next PageWhat to do if the load indicator is flashing on my UEIUA CMTP03-2405 Inverter and there is no output?
If the load indicator on your UEIUA Inverter is flashing and there is no output, it likely indicates an overcurrent or short circuit protection state. The controller will automatically resume normal operation about 3 seconds after the issue is resolved.
What to do if the battery Overlow indicator is ON, but the load does not start on UEIUA Inverter?
If the battery Overlow indicator (red light) is ON, but the load does not start on your UEIUA Inverter, it means the battery is low. The controller will not start until the battery voltage reaches the normal voltage (12.2V). The load will restart automatically once the voltage is normal.
How to fix the issue when the load could not close on UEIUA CMTP03-2405 Inverter?
If the load on your UEIUA Inverter could not close, check the mode setting. Connect the Inverter with the solar module and check whether the controller meets the load close condition or not.
Why is the charging indicator flashing on my UEIUA CMTP03-2405 Inverter?
If the charging indicator is flashing on your UEIUA Inverter, it indicates that the battery voltage exceeds 13.8V, and the system has entered a float charge state.
How to troubleshoot when all the indicators are OFF on UEIUA Inverter?
If all the indicators are OFF on your UEIUA Inverter, check the battery wiring to ensure it is well connected and tight. Also, verify that the battery voltage is within the normal range.
What to check if charging indicator is OFF during daytime on UEIUA CMTP03-2405 Inverter?
If the charging indicator is OFF during daytime when sunshine falls on PV modules properly for your UEIUA Inverter, check the PV and battery wires to ensure they are well connected and tight.
