What to do if Huawei SUN2000-4.6KTL-L1 Inverter displays String Reversed?
If your Huawei Inverter displays a String Reversed error, it means the PV string is reversely connected. Check whether the PV string is reversely connected to the SUN2000. If it is, wait until the PV string current decreases below 0.5 A, set the DC switch to OFF, and adjust the PV string polarity.
What to do if my Huawei SUN2000-4.6KTL-L1 Inverter showing Overtemperature?
If your Huawei Inverter is showing an Overtemperature warning, it indicates that the unit is installed in a location with poor ventilation, the ambient temperature is too high, or the SUN2000 is not working properly. You should check the ventilation and ambient temperature of the SUN2000 installation position. If the ventilation is poor or the ambient temperature exceeds the upper threshold, improve the ventilation and heat dissipation.
What to do if Huawei Inverter displays DC Arc Fault?
If your Huawei Inverter displays a DC Arc Fault, it means the PV string power cables are arcing or have poor contact. You should check whether the string cables arc or are in poor contact.
Why is my Huawei SUN2000-4.6KTL-L1 Inverter showing High String Input Voltage?
If your Huawei Inverter displays a High String Input Voltage error, it's because the PV array is not properly configured. Specifically, too many PV modules are connected in series, causing the open-circuit voltage to exceed the SUN2000's maximum operating voltage. To resolve this, check the serial connection configuration of the PV string and ensure that the PV string open-circuit voltage does not exceed the SUN2000's maximum operating voltage. After correcting the PV array configuration, the alarm should disappear.
