What does it mean if my Hoymiles Inverter displays 'Input port 5&6 overvoltage'?
Please make sure that the PV module open-circuit voltage is less than or equal to the maximum input voltage. If the PV module open-circuit voltage is within the normal range, contact your dealer or Hoymiles technical support.
What does it mean if my Hoymiles Inverter displays 'Input port 3&4 overvoltage'?
Please make sure that the PV module open-circuit voltage is less than or equal to the maximum input voltage. If the PV module open-circuit voltage is within the normal range, contact your dealer or Hoymiles technical support.
What does it mean if my Hoymiles Inverter displays 'Input port 1&2 overvoltage'?
Please make sure that the PV module open-circuit voltage is less than or equal to the maximum input voltage. If the PV module open-circuit voltage is within the normal range, contact your dealer or Hoymiles technical support.
What does 'Abnormal wiring of grid neutral line' mean on my Hoymiles Inverter?
Please confirm whether the grid neutral lines of the microinverters are connected to the neutral of the grid correctly.
What should I do if my Hoymiles Inverter shows 'Firmware error'?
Check if the firmware is correct and upgrade again. Check the communication between the DTU and Hoymiles monitoring system, and the communication between the DTU and microinverter. Then try again. If the fault persists, contact your dealer or Hoymiles technical support.
How do I resolve a 'Grid configuration parameter error' on my Hoymiles Inverter?
Check if the grid configuration parameter is correct and upgrade again. If the fault still exists, contact your dealer or Hoymiles technical support.
What does it mean if my Hoymiles Inverter reports a grid disconnection?
Please check whether the AC switch or AC wiring is normal.
What should I check if my Hoymiles Inverter indicates a power grid outage?
Please check whether there is a power grid outage.
What does it mean if my Hoymiles Inverter detects an island?
If the alarm occurs accidentally, the grid voltage may be abnormal temporarily. The microinverter can recover automatically after grid voltage becomes normal. If the alarms occur frequently on all the microinverters in your station, contact the local power operator to check whether there is a grid island. If the alarm still exists, contact your dealer or Hoymiles technical support.
How to fix over temperature protection on Hoymiles Inverter?
First, check the ventilation and ambient temperature at the microinverter's installation location. If ventilation is poor or the ambient temperature exceeds the limit, improve ventilation and heat dissipation. If both ventilation and ambient temperature meet the requirements, contact your dealer or Hoymiles technical support.
