What to do if my Hoymiles HMS-400-1T has a firmware error?
Check if the Hoymiles Inverter firmware is correct and has been upgraded. Then, check the communication between the DTU and the Hoymiles monitoring system, and between the DTU and the microinverter. Try again after checking the communication. If the fault persists, further assistance may be needed.
What to do if my Hoymiles Inverter shows grid overvoltage?
If the Hoymiles Inverter alarm occurs occasionally, the grid voltage may be temporarily abnormal, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm occurs frequently, verify that the grid voltage is within the acceptable range. If it's not, contact your local power operator or, with their consent, adjust the grid overvoltage protection limit in the grid profile via the Hoymiles monitoring system.
What to do if my Hoymiles Inverter shows 10 min value grid overvoltage?
If the Hoymiles Inverter alarm occurs occasionally, the grid voltage may be temporarily abnormal, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm occurs frequently, verify that the grid voltage is within the acceptable range. If it's not, contact your local power operator or adjust the grid overvoltage protection limit via Hoymiles monitoring system with their consent.
Why is my Hoymiles HMS-400-1T Inverter 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.
How to troubleshoot over temperature protection on a Hoymiles HMS-400-1T Inverter?
Check the ventilation and ambient temperature at the Hoymiles microinverter's installation location. If ventilation is poor or the ambient temperature exceeds the limit, improve ventilation and heat dissipation. If the problem persists with adequate ventilation and temperature, further assistance may be needed.
What to do if my Hoymiles HMS-400-1T was shut down by remote control?
Check the status of zero export management and whether the Hoymiles microinverters were manually shut down. If the alarm still persists, further assistance may be needed.
What to do if there is a grid configuration parameter error on my Hoymiles Inverter?
Check if the grid configuration parameter is correct and upgrade it. If the fault still exists, further assistance may be needed.
