What to do if REFU REFUsol 10K Inverter showing overtemperature LT 1?
If your REFU Inverter displays an overtemperature LT 1 error, it indicates a cooler overtemperature (right). Check the temperature of the direct surroundings and reduce it as required.
Why REFU REFUsol 10K Inverter shows external cut-off error?
If your REFU Inverter detects an external cut-off, it means external monitoring has triggered a disconnection. Verify the external cut-off signal. Possible causes include wire breakage or a wrong sensor selection. Refer to the manual for the correct settings.
How to troubleshoot PM isolation RCD SR error on REFU REFUsol 10K?
If your REFU Inverter shows a PM isolation RCD SR error, it means the measured value of the residual currents are over the limits. Check system isolation. If you consider the system isolation to be in order, contact Service.
What causes grid frequency LT error in REFU REFUsol 10K Inverter?
If your REFU Inverter displays a grid frequency LT error, it means the power section has detected under/overfrequency. Check the frequency of the phases. If you consider the frequencies to be in order, contact the Service.
Why REFU REFUsol 10K showing overvoltage 2?
If your REFU Inverter detects overvoltage 2, the phase voltage has exceeded the limit value of the voltage average monitor for too long. Monitor line voltages and analyze the grid. If the line voltages appear to be in order, contact Service.
What to do if REFU REFUsol 10K showing overfrequency?
If your REFU Inverter is detecting an overfrequency, it means the grid frequency has exceeded the limit value. Check the frequency of the phases. If you believe the frequencies are normal, contact Service.
How to fix grid overvoltage on REFU REFUsol 10K Inverter?
If your REFU Inverter displays a grid overvoltage error, it means a phase overvoltage (AC) has been detected. Check the phase voltages using a true RMS measurement device. If the phase voltages appear normal, contact Service.
