<p>Fortress Power Avalon BMS module — Battery Management System (AV-BMS)
The Fortress Power Avalon Battery Management System - AV-BMS is essential for the safe and smart operation of Avalon energy storage stacks. Designed for advanced lithium stacks, it acts as the system’s brain. It constantly monitors, balances, and safeguards each battery module. Whether in residential or commercial setups, the AV-BMS guarantees long-term safety and durability.

Designed for precision, the Fortress Avalon BMS module 1 per Battery Stack is vital for every Avalon stack. It optimizes energy handling to maintain consistent performance.

Fortress Avalon BMS module functions as the “brain” of the high-voltage stack. It handles cell monitoring, pack protection, and communication. This top-mounted device offers quick installation and includes a DC breaker, power button, status LED, and ports such as BMU, Heater, COM, and P+/P− power bus.
