Learn about the BMS Comm Error on Fortress Power Flex Tower and how to resolve it.
The BMS Comm Error indicates a communication issue between the battery management system and the inverter. This can lead to performance problems.
To troubleshoot, check all connections between the battery and inverter. Ensure firmware is updated and reset the system if necessary.
The BMS Comm Error indicates that the inverter has lost communication with the Battery Management System. This can occur due to several electrical logic failures. For instance, if the insulation resistance (RISO) measurement is out of tolerance, it can trigger a fault to prevent unsafe operation. Ground fault detection systems may also intervene if they detect anomalies in current flow. Furthermore, the inverter may monitor grid frequency limits, and if the BMS is unable to communicate its operational status, the inverter will default to a safe state, preventing energy production.
When the Fortress Power Flex Tower displays a "BMS Comm Error," users may observe a specific LED pattern on the unit, often blinking in a sequence that indicates a communication fault. In addition, the associated monitoring app may show alerts regarding battery status, and the overall system performance may drop, with reduced output from the inverter.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical components to ensure safety and compliance with local codes.
To avoid future occurrences of the BMS Comm Error, regularly inspect and maintain wiring and connectors, ensuring they are clean and secure. Keep the BMS in a well-ventilated area to prevent overheating, and perform routine firmware updates as recommended by the manufacturer. Additionally, periodically review system configurations to ensure compatibility between the inverter and BMS settings.
