What does Hardware Error Code 308 mean on my Hoymiles Inverter?
If the Hoymiles Inverter shows Hardware Error Code 308, and the microinverter still operates normally, no specific action is needed if the alarm occurs infrequently.
What to do if my Hoymiles HM-1500 Inverter shows a grid overvoltage alarm?
If the Hoymiles inverter alarm for 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.
What should I do if my Hoymiles Inverter 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.
What should I do if my Hoymiles HM-1500 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 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 does Hardware Error Code 302 mean on my Hoymiles HM-1500?
If the Hoymiles Inverter shows Hardware Error Code 302, and the microinverter still operates normally, no specific action is needed if the alarm occurs infrequently. However, if the alarm appears frequently and cannot be resolved, contact your dealer or Hoymiles technical support.
What does Hardware Error Code 301 mean on my Hoymiles HM-1500?
If the Hoymiles Inverter shows Hardware Error Code 301, and the microinverter still operates normally, no specific action is needed if the alarm occurs infrequently. However, if the alarm appears frequently and cannot be resolved, contact your dealer or Hoymiles technical support.
What does Software error code 129 mean on my Hoymiles Inverter?
If the Hoymiles Inverter shows Software Error Code 129, and the microinverter still operates normally, no specific action is needed if the alarm occurs infrequently. However, if the alarm appears frequently and cannot be resolved, contact your dealer or Hoymiles technical support.
What does it mean when my Hoymiles Inverter displays 'Port No input'?
If the Hoymiles Inverter displays 'Port No input', first confirm whether the port is connected to the PV module. If the PV module is connected, check the DC cable connection between this port and the PV module.
Why is my Hoymiles Inverter showing as offline?
If your Hoymiles Inverter is offline, first ensure that the microinverter is working correctly. Then, check the communication status between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter. If the alarm occurs frequently and cannot be recovered, contact your dealer or Hoymiles technical support.
This document provides a comprehensive user manual for the Hoymiles HM-1000/HM-1200/HM-1500 Single-phase Microinverter, a key component in photovoltaic (PV) systems designed to convert direct current (DC) into alternating current (AC) for feeding into the public grid. This system is composed of multiple microinverters, with each unit supporting up to two PV modules. Each microinverter operates independently, optimizing power generation from individual PV modules and enhancing system flexibility and reliability.
The Hoymiles HM-1000/HM-1200/HM-1500 Microinverter is a "Daisy-Chain 4-in-1 Unit Microinverter" that features an ultra-wide DC input operating voltage range of 16 V to 60 V and a low start-up voltage of only 22 V. This design makes it a reliable solution for PV systems, particularly those with an uneven number of panels. The microinverter's primary function is to convert the DC power generated by PV modules into AC power, which can then be used to support household loads or fed into the public grid.
The microinverter operates in several modes:
The microinverter is designed for high efficiency, boasting a peak efficiency of 96.70% and a CEC weighted efficiency of 96.50%. It also features a static MPPT (Maximum Power Point Tracking) efficiency of 99.80% and a dynamic MPPT efficiency of 99.76% in overcast weather, ensuring optimal power harvesting under varying environmental conditions. The power factor is adjustable from 0.8 leading to 0.8 lagging, providing flexibility for grid integration.
The HM-1000/HM-1200/HM-1500 Microinverter is designed for straightforward installation and integration into PV systems. It supports maximum output powers of up to 1000 W, 1200 W, and 1500 W, respectively, and is compatible with both 60-cell and 72-cell PV panels.
Key usage features include:
Routine maintenance is crucial for the long-term performance and safety of the microinverter system. The manual outlines several maintenance features and guidelines:
This comprehensive approach to function, usage, and maintenance ensures that the Hoymiles HM-1000/HM-1200/HM-1500 Microinverter provides a reliable, efficient, and safe solution for PV power generation.
