What to do if my Hoymiles Inverter has a firmware error?
First, check if the firmware is correct and properly upgraded. Then, verify the communication between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter. Try again after checking the communication.
What to do if my Hoymiles HMS-800-2T shows grid overvoltage?
If the grid overvoltage alarm occurs occasionally, it might be due to a temporary grid voltage fluctuation, and the Hoymiles microinverter should automatically recover once the voltage returns to normal. However, if the alarm appears frequently, verify that the grid voltage is within the acceptable range. If it's consistently outside the range, contact your local power operator or, with their consent, adjust the grid overvoltage protection limit through the Hoymiles monitoring system.
Why does my Hoymiles HMS-800-2T Inverter show a 10 min value grid overvoltage?
An occasional 10-minute grid overvoltage alarm on your Hoymiles Inverter may indicate a temporary grid voltage abnormality, from which the microinverter should automatically recover. However, frequent alarms suggest checking if the grid voltage is within the acceptable range. If not, contact the local power operator or, with their consent, change the grid overvoltage protection limit via the Hoymiles monitoring system.
What to do if my Hoymiles HMS-800-2T is overheating?
Check the ventilation and ambient temperature at the microinverter installation location. If ventilation is poor or the ambient temperature exceeds the limit, improve the ventilation and heat dissipation.
Why does my Hoymiles HMS-800-2T Inverter show abnormal bias?
If the abnormal bias alarm occurs occasionally and the microinverter continues to operate normally, no action is needed.
What to do if my Hoymiles HMS-800-2T Inverter was shut down by remote control?
Check the status of zero export management and whether the microinverters were manually shut down.
