The Fogstar Energy 32kWh is a high-capacity 51.2V LiFePO4 battery for off-grid systems, backup power, renewable installs and larger commercial or industrial sites, with safety and performance built into the design from the start.
This 2026 model brings built-in fire suppression and integrated battery heating, keeping the battery working reliably in the cold and adding internal protection should a fault occur. It's well suited to cooler indoor plant rooms and winter installs.
Charge, discharge and cell health are handled by a 300A Seplos Battery Management System (BMS) with an inbuilt 2A JK Active Balancer, giving accurate cell monitoring, balanced cells and a long service life under heavy use.
Battery Management
A 300A Seplos BMS works alongside a 2A JK Active Balancer to monitor every cell, keep them balanced and protect long-term battery health.
Built-In Fire Suppression
A heat-triggered aerosol fire suppression unit sits inside the battery enclosure, responding automatically to thermal events with no external equipment needed.
Integrated Heating
On-board heating allows safe charging down to -10°C, keeping cells at a healthy temperature through the winter and protecting capacity and lifespan.
Inverter Compatibility
Protocols pre-loaded for popular inverters including LuxPower, Sunsynk, Solis, Victron and more.
