If the Hoymiles Inverter shows a firmware error, check if the firmware is correct and upgrade again. Also, check the communication between the DTU and the Hoymiles monitoring system, as well as the communication between the DTU and the microinverter. If the fault persists, contact your dealer or Hoymiles technical support.
What does it mean when my Hoymiles MI-1500 Inverter says 'Island detected'?
If the Hoymiles Inverter displays an 'Island detected' alarm, it could be due to a temporary grid voltage issue, in which case the microinverter should recover automatically once the grid voltage stabilizes. If the alarms occur frequently on all microinverters in your station, contact your local power operator to check for a grid island. If the alarm persists, contact your dealer or Hoymiles technical support.
How to troubleshoot over temperature protection on my Hoymiles MI-1500 Inverter?
To address the over temperature protection issue with your Hoymiles Inverter, you should: 1. Check the ventilation and ambient temperature at the microinverter installation position. 2. If the ventilation is poor or the ambient temperature exceeds the limit, improve the ventilation and heat dissipation. 3. If both the ventilation and ambient temperature meet the requirements, contact your dealer or Hoymiles technical support.
What should I do if my Hoymiles Inverter is showing a grid underfrequency alarm?
If the Hoymiles inverter alarm for grid underfrequency occurs accidentally, the grid frequency may be abnormal temporarily and the microinverter can recover automatically after grid frequency becomes normal. If the alarm occurs frequently, check whether the grid frequency is within the acceptable range.
What does it mean when my Hoymiles MI-1500 shows a 'Rapid grid frequency change rate' alarm?
If the Hoymiles inverter alarm for rapid grid frequency change rate occurs accidentally, the grid frequency may be abnormal temporarily and the microinverter can recover automatically after grid frequency becomes normal. If the alarm occurs frequently, check whether the grid frequency change rate is within the acceptable range. If not, contact the local power operator or change the grid frequency change rate limit via Hoymiles monitoring system with the consent of the local power operator.
What should I do if my Hoymiles Inverter displays a grid overfrequency alarm?
If the Hoymiles inverter alarm for grid overfrequency occurs accidentally, it may be a temporary issue. The microinverter should recover automatically when the grid frequency returns to normal. If the alarm occurs frequently, check if the grid frequency is within the acceptable range. If it is not, contact your local power operator or, with their consent, change the grid overfrequency protection limit via the Hoymiles monitoring system.
What should I do if my Hoymiles MI-1500 Inverter shows a grid undervoltage error?
If the Hoymiles inverter alarm for grid undervoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm appears frequently, verify that the grid voltage is within the acceptable range. If not, contact the local power operator or change the grid undervoltage protection limit via Hoymiles monitoring system with the consent of the local power operator. If the fault still exists, check the AC switch or AC wiring.
What should I do if my Hoymiles MI-1500 displays a '10 min value grid overvoltage' error?
If the Hoymiles inverter alarm for 10 min value grid overvoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. 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 through the Hoymiles monitoring system.
