Discover the causes and solutions for BYD charging errors in solar systems.
Charging errors can occur due to battery overvoltage, temperature issues, or connection problems. It's essential to check the battery status and connections.
To reset your BYD system, turn off the power supply and wait for a few minutes. Then, turn it back on and check if the error persists.
The inverter is designed to monitor the charging conditions of the battery and will trigger a fault if any parameters fall outside acceptable ranges. This could be due to insufficient string voltage, which may arise from shading or soiling of the solar array. The inverter also employs ground fault detection to ensure safety; if a fault is detected, it will shut down charging to prevent further damage. Additionally, overvoltage conditions from the utility grid can cause the inverter to enter a protective mode, halting charging until conditions normalize.
Homeowners may observe an error code displayed on the inverter screen, often accompanied by specific LED patterns indicating a charging error. The monitoring app may show a production drop or a halt in charging, with alerts indicating issues with the battery performance or grid connection.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical issues to ensure safety and compliance with local codes.
To prevent future charging errors, ensure regular maintenance of the solar array, including cleaning and inspection for shading issues. Periodically check the battery health and conduct insulation resistance tests. Keep firmware updated on the inverter and BMS to address any potential communication issues.
