The Fogstar Energy IP65-Rated 16.1kWh Battery, meticulously engineered for UK conditions, delivers a robust combination of advanced LiFePO4 battery technology, integrated safety systems, and long-term durability.

Designed for both indoor and outdoor installation, the Fogstar Energy IP65-Rated 16.1kWh Battery provides reliable performance in demanding environments. Its fully sealed construction, intelligent thermal management, and wide inverter compatibility make it a dependable solution for long-term energy storage.

This 16.1kWh solar battery boasts numerous advanced features, including:

Built-In Fire Suppression & IP65 Protection
The battery is housed in a fully sealed IP65-rated enclosure, protecting internal components against dust ingress and water jets from any direction. An automatic, built-in aerosol fire suppression system activates if internal temperatures reach critical levels, helping to suppress fire at the source with zero maintenance required.

Intelligent Heating System
The integrated heating system automatically activates when temperatures drop below 5°C, enabling safe charging at 0°C and reliable operation in ambient temperatures as low as -20°C.

Plug-and-Play Inverter Compatibility
The PACE Battery Management System (BMS) contains pre-loaded inverter protocols for Victron, Pylontech, Growatt, Sofar, Solis, and Goodwe. Inverter protocol selection can be changed directly via the LCD touchscreen without the need for software downloads.

Premium Grade A EVE Cells
The Fogstar Energy IP65-Rated 16.1kWh Battery utilises 16 MB31 Grade A EVE LiFePO4 cells, delivering an exceptional cycle life of up to 8,000 cycles at 80% DOD (95% DOD as of February 2026).

Active Balancing
Equipped with a 2A JK Active Balancer to ensure consistent cell balancing and improved long-term performance.

Scalable Energy Storage: Up to 15 batteries can be connected in parallel, allowing total system capacity to be expanded as energy requirements grow.

Enhanced Safety with DC Breaker: Each battery includes an integrated 250A DC breaker, providing critical protection by safely interrupting current in the event of a fault.

Intuitive Touchscreen Interface: The 4.3-inch TFT LCD touchscreen provides a clear and user-friendly interface for monitoring system status and selecting inverter protocols.

Energy-Efficient Sleep Mode: When not in use, the touchscreen automatically enters sleep mode to conserve energy, while allowing instant access to system information with a simple touch.

Wheels for Portability: Despite its robust construction, integrated wheels make the battery significantly easier to manoeuvre during installation or maintenance.

Simplified Installation: All batteries are supplied with M8 ring terminals and protective covers for straightforward and secure installation.

Fogstar Energy supports this battery with a 10-year warranty, reflecting confidence in its design, construction, and long-term reliability.
