What to do if Huawei SUN2000-175KTL-H0 shows 'Grid Code Map not supported'?
If the Huawei Inverter displays a 'Grid Code Map not supported' error, it means that the current grid code settings might not be compatible with the inverter's supported configurations. To resolve this, review the grid code settings to ensure they match compatible configurations.
What to do if Huawei SUN2000-175KTL-H0 Inverter shows Grid Loss?
A 'Grid Loss' alarm on your Huawei Inverter indicates either a power grid outage or a disconnection in the AC circuit, or the AC switch is off. The alarm should clear automatically once the power grid is restored. In the meantime, check if the AC circuit is disconnected, or the AC switch is off.
Why is the string input voltage too high on my Huawei SUN2000-175KTL-H0?
A high string input voltage on your Huawei Inverter occurs when the PV array is improperly configured, meaning too many PV modules are connected in series, causing the PV string open-circuit voltage to exceed the inverter's maximum operating voltage. To fix this, reduce the number of PV modules connected in series until the PV string open-circuit voltage is within the inverter's acceptable range. The alarm should disappear after correcting the PV array configuration.
What causes Grid Overvoltage on a Huawei SUN2000-175KTL-H0 Inverter?
Grid overvoltage in your Huawei Inverter means the grid voltage is beyond the upper threshold, or the overvoltage duration has exceeded the time that triggers HVRT. First, check whether the grid connection voltage exceeds the upper threshold and contact the local power operator if it does. If you have confirmed that the grid connection voltage exceeds the upper threshold and obtained consent from the local power operator, modify the overvoltage protection threshold. Also, check whether the peak grid voltage exceeds the upper threshold.
How to troubleshoot abnormal grounding on Huawei SUN2000-175KTL-H0 Inverter?
Abnormal grounding in your Huawei Inverter can occur if the PE cable of the inverter isn't properly connected, or if the inverter output side doesn't connect to an isolation transformer when the PV string output is grounded. Ensure the PE cable of the inverter is correctly connected. If the PV string output is grounded, verify that the inverter output side connects to an isolation transformer.
What to do if my Huawei Inverter has a Device Fault?
A device fault on your Huawei Inverter indicates an unrecoverable fault has occurred on a circuit inside the inverter. Turn off the AC output switch and DC input switch, and then turn them on after 15 minutes. If the fault persists, contact your dealer.
What does Output DC Component Overhigh mean on Huawei SUN2000-175KTL-H0 Inverter?
Output DC component overhigh on your Huawei Inverter means the DC component of the inverter output current exceeds the specified upper threshold. If the exception is caused by an external fault, the inverter automatically recovers after the fault is rectified.
How to fix Huawei SUN2000-175KTL-H0 when the external fan is abnormal?
An abnormal external fan on your Huawei Inverter could be due to a short circuit, insufficient power supply, or a blocked air channel. Shut down the fan, turn off the DC switch, check for damage to the fan blades, and clear any foreign matter around the fan. Reinstall the fan, turn on the DC switch, and wait for the inverter to start. If the fault persists after 15 minutes, replace the external fan.
Why is the string power abnormal on my Huawei Inverter?
Abnormal string power in your Huawei Inverter can be due to the PV string being shaded from sunlight for a long time or the PV string aging abnormally. Check if the current of the abnormal PV string is lower than that of other PV strings. If it is, check whether the abnormal PV string is shaded and if the actual number of PV strings is the same as the configured number. If the abnormal PV string is clean and not shaded, check whether the PV string is damaged.
What causes Cabinet Overtemperature on a Huawei SUN2000-175KTL-H0 Inverter?
Cabinet overtemperature in your Huawei Inverter can occur due to poor ventilation, high ambient temperature, or the inverter not working properly. Check the ventilation and whether the ambient temperature exceeds the upper limit. If ventilation is poor or the ambient temperature is too high, improve ventilation.
