Learn how to troubleshoot and resolve Solis Error Code 1045 related to grid overvoltage alarms.
Error Code 1045 indicates a grid overvoltage condition that needs to be addressed to ensure system safety.
Regularly monitor grid voltage levels and ensure your inverter settings are optimized for local conditions.
Error 1045 is triggered when the inverter detects a grid overvoltage condition, which occurs when the voltage supplied by the utility grid exceeds the inverter's maximum input voltage threshold. This is a safety feature designed to protect both the inverter and the solar array from potential damage. The inverter continuously monitors grid voltage and frequency to ensure compliance with the National Electrical Code (NEC) and to prevent unsafe operating conditions. If the measured voltage exceeds the predetermined limits, the inverter will disconnect from the grid to avoid damaging internal components.
When experiencing Solis Error 1045, users may observe the inverter's LED indicator flashing a specific pattern, typically red or orange, signaling an alarm condition. Additionally, the monitoring app may display a grid overvoltage alert, and system performance may drop significantly, showing lower energy production or complete shutdown of the inverter.
Always consult a licensed electrician or certified solar installer when dealing with electrical issues or performing maintenance on your solar system. Safety is paramount, and improper handling can lead to serious injury or equipment damage.
To prevent future occurrences of Error 1045, regularly monitor grid voltage levels through the inverter's monitoring system and ensure that the inverter firmware is updated. Consider installing surge protection devices to mitigate the effects of voltage spikes and ensure proper grounding of the system to enhance stability. Regular maintenance checks by a certified solar installer can also help identify potential issues before they escalate.
