What to do if the country setting is invalid on my Sofar solar Inverter?
Check the country setting of your Sofar solar Inverter according to Section 6.3 (C) 5.Country of this user manual. If it’s incorrect, change it according to Section 6.3 (A) 4.Set Country Code of this manual.
What to do if the power grid voltage is too high on my Sofar solar SOFAR 7.5KTLM?
If the Sofar solar inverter grid voltage alarm occurs occasionally, it might be due to temporary grid issues; the inverter should automatically resume normal operation when the grid stabilizes. If the alarm is frequent, verify that the grid voltage and frequency are within the correct range. If they aren't, contact technical support. If they are, inspect the AC circuit breaker and AC wiring of the inverter. If the grid voltage and frequency are correct, and the wiring is also correct, but the alarm persists, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection settings, but only after obtaining approval from your local electrical grid operator.
Why is my Sofar solar SOFAR 7.5KTLM Inverter temp too high?
Ensure that the installation position and method comply with the guidelines in Section 3.4 of the user manual. Verify that the ambient temperature at the installation site does not exceed the specified upper limit. If it does, improve ventilation to lower the temperature.
Why is my Sofar solar SOFAR 7.5KTLM derating because of high temperature?
Ensure that the installation position and method comply with the guidelines in Section 3.4 of the user manual. Verify that the ambient temperature at the installation site does not exceed the specified upper limit. If it does, improve ventilation to lower the temperature.
What to do if the input voltage is too high on my Sofar solar SOFAR 7.5KTLM?
If too many PV modules are connected in series in a PV string, the voltage (Voc) of the PV string might exceed the maximum input voltage of your Sofar solar Inverter. If this is the case, adjust the number of PV modules connected in series to reduce the voltage of the PV string, ensuring it remains within the inverter's input voltage range. After making these adjustments, the inverter should automatically return to normal operation.
What to do if the input voltage is too low on my Sofar solar Inverter?
If too few PV modules are connected in series in a PV string, the voltage (Vmp) of the PV string might be lower than the minimum operating voltage of your Sofar solar Inverter. If this is the case, adjust the number of PV modules connected in series to increase the voltage of the PV string, ensuring it fits within the inverter's input voltage range. After making these adjustments, the inverter should automatically return to normal operation.
What to do if the bus voltage is too low on my Sofar solar Inverter?
If the PV array configuration is correct and there is no ID05 fault, the solar irradiance may be too low. Your Sofar solar Inverter should automatically return to normal operation once the solar irradiance increases to a normal level.
What to do if the input current is not balanced on my Sofar solar SOFAR 7.5KTLM Inverter?
Check the input mode (parallel mode or independent mode) setting of your Sofar solar Inverter according to Section 6.3 (C) 6.Input Mode of this user manual. If it’s incorrect, change it according to Section 6.3 (A) 10.Set Input mode of this manual.
What to do if the SD card is faulty on my Sofar solar SOFAR 7.5KTLM?
Please replace the SD card in your Sofar solar Inverter.
