Learn how to troubleshoot and resolve the High Voltage error on LG RESU10H batteries in SolarEdge systems.
A High Voltage error typically indicates that the battery voltage has exceeded safe operating limits, which can affect performance.
Regular maintenance and monitoring of battery health can help prevent High Voltage errors by ensuring proper charging and discharging cycles.
The 'High Voltage' error is triggered when the inverter detects voltage levels exceeding the operational limits defined in the National Electrical Code (NEC). This can occur due to several factors, including RISO measurements that indicate insulation failure, ground fault detection triggering due to imbalances, or grid frequency limits being exceeded. The inverter is designed to protect the battery and connected systems by shutting down to prevent damage, ensuring safety and compliance with electrical standards.
Homeowners may observe a warning alert on the SolarEdge monitoring app indicating a 'High Voltage' condition. The inverter's LED indicator may flash red or display a fault code related to voltage issues. Additionally, energy production may be significantly reduced or halted altogether, leading to decreased system performance.
Always consult a licensed electrician or certified solar installer when addressing electrical issues to ensure safety and compliance with local regulations.
To prevent future occurrences of the 'High Voltage' error, ensure regular maintenance checks on the entire solar power system, including battery health assessments and inverter settings verification. Periodically inspect wiring and connections for integrity, and ensure the system is designed to accommodate local environmental conditions.
