  Each stack is built from three (3) or four (4) 16.1kWh battery modules, depending on the purchased option, making installation, handling and future expansion significantly easier. A single top-mounted control unit manages the entire stack as one integrated system, underpinned by a battery base plate. Multiple stacks can be connected in parallel, allowing the system to scale from a single 48.3kWh stack up to a full 1.23MWh system if required. With an IP-rated enclosure, integrated heating and built-in fire suppression, the system is engineered for safe, reliable operation in demanding environments. Key Features 48.3kWh per StackEach stack provides 48.3kWh of total energy, assembled from three 16.1kWh LiFePO₄ battery modules for easier installation and servicing. Advanced Battery Management SystemAn Integrated BMS delivers precise control, comprehensive protection and long-term system reliability, with support for high-power operation. Simple Integration with Major Inverter BrandsCAN and RS485 communication enable seamless integration with popular inverter brands, including Victron, LuxPower, Sunsynk, Solis, Voltronic, Voltacon and more. Scalable Energy StorageScales from a single 48.3kWh stack up to a full 1.23MWh system if required. IP65-Rated ConstructionRobust, sealed enclosure protects against dust and moisture, making the system suitable for indoor and outdoor installations. Integrated Fire SuppressionBuilt-in, heat-activated aerosol fire suppression system provides fast, automatic internal protection with no ongoing maintenance. Cold-Weather ReadyIntegrated heating system enables safe charging at low temperatures and reliable operation in ambient conditions down to –15 °C. JK Active Cell Balancing2A active balancing continuously equalises cell voltages, improving efficiency, stability and overall battery lifespan. High Output PerformanceLV 51.2V (48V) system designed to support high-demand inverters and large backup or off-grid installations. Long-Term Peace of MindBacked by a 6-year warranty and 10 years of UK-based customer service support. User-Friendly InterfaceLCD touchscreen for real-time monitoring and system management. Built-in BreakerThe 350A breaker allows the entire system to be safely isolated during faults, maintenance, or emergency conditions. System Overview Each 48.3kWh stack is assembled from three (3) 16.1kWh battery modules housed within a single enclosure. Once stacked, a top-mounted control unit manages all modules as one unified battery system, simplifying commissioning, monitoring and maintenance. The modular design allows additional stacks to be added at any stage, making the system ideal for phased installations or growing energy requirements.

The system is supplied with pre-terminated 95 mm² battery power cables for straightforward installation. These enable direct connection between the battery system and inverter, or via an external busbar where required.  Battery to battery cables are terminated with Amphenol connectors for secure, low-resistance connections.  A 1.5 m communication cable are also supplied to enable system control and data integration. The supplied power cables are compatible with most inverter systems. In some installations, battery cables may be routed to a busbar, with manufacturer-supplied inverter leads used for the final connection. For correct installation, all negative connections must be made before connecting the positive.
