Advanced Battery Management
At the heart of the Fogstar Energy 32kWh battery is a 300A Seplos Battery Management System (BMS) paired with an integrated 2A JK Active Balancer.
The system provides cell monitoring and management while the active balancer helps maintain consistency between individual cells, supporting reliable performance and long-term battery health.
Integrated Fire Suppression
An automatic heat-activated aerosol fire suppression system is integrated directly into the battery enclosure.
This provides an additional internal safety system designed to respond to thermal events without requiring separate external fire suppression equipment.
Integrated Battery Heating
The battery incorporates an intelligent heating system designed to maintain suitable cell temperatures during cold-weather operation.
Fogstar specifies charging operation down to -10°C, making the battery suitable for installations where lower ambient temperatures may be encountered.
Inverter Communication & Compatibility
Preloaded inverter protocols allow the battery to communicate with a range of commonly used renewable energy inverter systems.
Fogstar lists compatibility with popular manufacturers including Victron, LuxPower, Solis, Sunsynk and Voltacon.
The integrated LCD touchscreen provides access to system information, diagnostics and controls directly from the battery.
Please check compatibility with your particular inverter model before purchasing or installing the battery.
Expandable Energy Storage
The Fogstar Energy 32kWh Battery can be used as part of a substantially larger energy storage system.
Up to 16 compatible units can be connected, making the system suitable for applications ranging from larger residential installations through to commercial and industrial energy storage.
