How to resolve a firmware error on a Hoymiles HMS-2000D-4T?
If you're encountering a firmware error with your Hoymiles Inverter, first, verify that the firmware is correct and has been upgraded. Next, check the communication between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter, and then try again. If the issue persists, contact your dealer or the Hoymiles technical support team.
What to do if my Hoymiles HMS-2000D-4T Inverter is offline?
If your Hoymiles Inverter is offline, first, ensure it's working correctly by checking if the DC voltage is within the normal range and observing the LED indicator. Next, verify that the serial number (SN) on the microinverter label matches the one on the monitoring platform. Then, assess the communication between the DTU and both the Hoymiles monitoring system and the microinverter, making improvements if the connection is poor. Should the issue persist frequently and remain unresolved, it is advisable to contact your dealer or the Hoymiles technical support team.
Why does my Hoymiles Inverter show a grid overvoltage error?
If your Hoymiles Inverter is showing a grid overvoltage alarm, and it happens occasionally, it might just be a temporary issue with the grid voltage. The inverter should automatically recover once the voltage returns to normal. However, if the alarm occurs frequently, check if the grid voltage is within the acceptable range. If it's not, you should contact your local power operator or, with their consent, adjust the grid overvoltage protection limit in the grid profile through the Hoymiles monitoring system.
How to fix over temperature protection on Hoymiles HMS-2000D-4T Inverter?
If your Hoymiles Inverter is experiencing over temperature protection issues, start by checking the ventilation and ambient temperature where the microinverter is installed. If ventilation is inadequate or the ambient temperature exceeds the limit, improve the ventilation and heat dissipation. If the problem continues even with proper ventilation and temperature, contact your dealer or the Hoymiles technical support team.
What to do if Hoymiles HMS-2000D-4T shows 10 min value grid overvoltage?
If your Hoymiles Inverter is showing a '10 min value grid overvoltage' alarm, and it occurs occasionally, it could be due to a temporary grid voltage fluctuation. The microinverter should automatically recover once the grid voltage stabilizes. However, if the alarm appears frequently, verify that the grid voltage is within the acceptable range. If it exceeds the limit, contact your local power operator or, with their approval, adjust the grid overvoltage protection limit via the Hoymiles monitoring system.
What to do if Hoymiles Inverter shows grid configuration parameter error?
If your Hoymiles Inverter displays a grid configuration parameter error, check if the grid configuration parameter is correct and upgrade it. If the fault persists, contact your dealer or the Hoymiles technical support team.
Why does my Hoymiles HMS-2000D-4T show an abnormal bias?
If your Hoymiles Inverter is showing an abnormal bias alarm, and it only happens occasionally while the microinverter continues to operate normally, no specific action is needed. However, if the alarm occurs frequently and the system cannot recover, contact your dealer or the Hoymiles technical support team.
What to do if Hoymiles HMS-2000D-4T Inverter shut down by remote control?
If your Hoymiles Inverter was 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, please contact your dealer or Hoymiles technical support team.
