How to fix firmware error on Hoymiles HMS-500-1A?
Verify that the firmware is correct and has been upgraded. Also, check the communication between the DTU and the Hoymiles monitoring system, and between the DTU and the microinverter. After checking this, try again. If the issue persists, further assistance may be needed.
What to do if my Hoymiles HMS-500-1A Inverter is offline?
First, ensure the Hoymiles microinverter is working correctly by checking if the DC voltage is within the normal range and confirming the LED indicator status. Next, verify that the serial number (SN) on the microinverter label matches the one on the monitoring platform. Then, check the communication status between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter. If the communication is poor, try to improve it. If the alarm persists and cannot be resolved, further assistance may be needed.
What to do if Hoymiles Inverter shows grid overvoltage?
If the grid overvoltage alarm occurs occasionally, it may be a temporary grid issue, and the Hoymiles microinverter should automatically recover once the grid voltage returns to normal. However, if the alarm appears frequently, verify that the grid voltage is within the acceptable range. If it's not, you may need to contact your local power operator or, with their consent, adjust the grid overvoltage protection limit in the grid profile via the Hoymiles monitoring system.
How to fix over temperature protection on Hoymiles Inverter?
Check the ventilation and ambient temperature at the location where the microinverter is installed. If ventilation is poor or the ambient temperature exceeds the limit, improve ventilation and heat dissipation. If the problem persists despite proper ventilation and temperature, further assistance may be needed.
What to do if Hoymiles HMS-500-1A shows grid configuration parameter error?
Check if the grid configuration parameter is correct and upgrade it. If the fault still exists, further assistance may be needed.
Why my Hoymiles HMS-500-1A Inverter shut down by remote control?
Check the status of zero export management and whether the microinverters were manually shut down. If the alarm still persists, further assistance may be needed.
What to do if Hoymiles HMS-500-1A Inverter shows abnormal bias?
If the alarm occurs occasionally and the microinverter continues to operate normally, no specific action is required. However, if the alarm appears frequently and cannot be resolved, further assistance may be needed.
