What to do if Hoymiles Inverter shows firmware error?
Check if the firmware is correct and upgrade again. Also, check and ensure proper communication between the DTU, Hoymiles monitoring system, and the microinverter; retry if needed. If the fault still exists, contact your dealer or Hoymiles technical support.
What to do if my Hoymiles Inverter is offline?
First, ensure the microinverter is functioning correctly. Then, check the communication status between the DTU and the Hoymiles monitoring system, or between the DTU and the microinverter; try to improve the communication if it's poor. If the issue persists, contact your dealer or Hoymiles technical support.
What to do if Hoymiles Inverter shows grid overvoltage?
If the alarm occurs accidentally, it's possible the grid voltage is temporarily abnormal; the microinverter should recover automatically once the voltage returns to normal. However, 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 via the Hoymiles monitoring system.
What to do if my Hoymiles Inverter shows '10 min value grid overvoltage'?
If this alarm appears once in a while, it might be due to a temporary issue with the grid voltage. The inverter should fix itself when the voltage goes back to normal. If it keeps happening, check if the grid voltage is within the right range. If it's not, get in touch with your local power company or, with their agreement, change the grid overvoltage protection limit using the Hoymiles monitoring system.
What to do if Hoymiles Inverter reports grid undervoltage?
If you see this alarm just once, it could be because the grid voltage is briefly not normal. The microinverter should automatically get back to normal when the grid voltage stabilizes. If it happens a lot, check to see if the grid voltage is in the right range. If it's not, contact your local power operator, or change the grid undervoltage protection limit through the Hoymiles monitoring system after getting permission from the local power operator.
What to do for over temperature protection in Hoymiles Inverter?
First, check the ventilation and ambient temperature where the microinverter is installed. If needed, improve ventilation and heat dissipation. If ventilation and temperature are within the correct range, contact your dealer or Hoymiles technical support.
What to do if Hoymiles Inverter displays grid configuration parameter error?
Check if the grid configuration parameter is correct and upgrade again. If the fault still exists, contact your dealer or Hoymiles technical support.
What to do if my Hoymiles Inverter shows software error code 126?
If the alarm occurs accidentally and the microinverter is still working properly, no special action is required. However, if the alarm occurs frequently and cannot be resolved, contact your dealer or Hoymiles technical support.
What to do if my Hoymiles Inverter shows software error code 128?
If the alarm occurs accidentally and the microinverter functions normally, no action is needed. If the alarm occurs frequently and cannot be recovered, contact your dealer or Hoymiles technical support.
What to do if my Hoymiles Inverter shows software error code 129?
If the alarm occurs accidentally and the microinverter can still work normally, no special treatment is required. If the alarm occurs frequently and cannot be recovered, contact your dealer or Hoymiles technical support.
