How to fix firmware error on Hoymiles HMS-500-1A?
Verify that the firmware is correct and has been upgraded. Also, check the communication between the DTU and the Hoymiles monitoring system, and between the DTU and the microinverter. After checking this, try again. If the issue persists, further assistance may be needed.
What to do if my Hoymiles HMS-500-1A Inverter is offline?
First, ensure the Hoymiles microinverter is working correctly by checking if the DC voltage is within the normal range and confirming the LED indicator status. Next, verify that the serial number (SN) on the microinverter label matches the one on the monitoring platform. Then, check the communication status between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter. If the communication is poor, try to improve it. If the alarm persists and cannot be resolved, further assistance may be needed.
What to do if Hoymiles Inverter shows grid overvoltage?
If the grid overvoltage alarm occurs occasionally, it may be a temporary grid issue, and the Hoymiles microinverter should automatically recover once the grid voltage returns to normal. However, 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 in the grid profile via the Hoymiles monitoring system.
How to fix over temperature protection on Hoymiles Inverter?
Check the ventilation and ambient temperature at the location where the microinverter is installed. If ventilation is poor or the ambient temperature exceeds the limit, improve ventilation and heat dissipation. If the problem persists despite proper ventilation and temperature, further assistance may be needed.
What to do if Hoymiles HMS-500-1A shows grid configuration parameter error?
Check if the grid configuration parameter is correct and upgrade it. If the fault still exists, further assistance may be needed.
Why my Hoymiles HMS-500-1A Inverter 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, further assistance may be needed.
What to do if Hoymiles HMS-500-1A Inverter shows abnormal bias?
If the alarm occurs occasionally and the microinverter continues to operate normally, no specific action is required. However, if the alarm appears frequently and cannot be resolved, further assistance may be needed.
This document describes the Hoymiles Single-phase Microinverter, models HMS-300-1A, HMS-350-1A, HMS-400-1A, HMS-450-1A, and HMS-500-1A. These microinverters are designed to convert direct current (DC) from photovoltaic (PV) modules into alternating current (AC) and feed the power to the public grid. Each microinverter operates independently, ensuring maximum power generation from each connected PV module. This independent operation contributes to a highly flexible and reliable system, allowing for direct control over the production of each PV module.
The core function of the Hoymiles Single-phase Microinverter is to facilitate the conversion of solar energy into usable electricity for the grid. It acts as a crucial component in a solar power system, taking the DC output from a single PV module and transforming it into AC power. This design contrasts with traditional string inverters, where multiple PV modules are connected in series. The microinverter's independent operation means that shading or performance issues on one module will not significantly impact the output of other modules in the system, thereby optimizing overall energy harvesting.
The microinverter is designed for easy integration into an AC module system, typically mounted on the PV module frame. Its AC-side output connectors are designed to connect to an AC Trunk Cable, which then facilitates connection to a distribution box and the local grid network. The system is compatible with Hoymiles gateway DTU-Pro-S and DTU-Lite-S for monitoring and data collection.
The Hoymiles Single-phase Microinverter series offers various power outputs, indicated by their model numbers (e.g., HMS-300-1A for 300W, HMS-500-1A for 500W).
