Start small, scale freely — stackable 48V home battery storage without the premium price tag.
The Fogstar Energy Stackable 48V 5.12kWh Battery is designed for off-grid homes, cabins, rural properties, and shepherd's huts that need flexible, expandable energy storage. Begin with a single 5.12kWh unit and add more as your system grows — there's no upper limit on parallel capacity, making it equally at home in a modest rural retreat or a larger off-grid property.
Built around Grade A LiFePO4 cells with a 100A BMS and an inbuilt 2A JK Active Balancer, this battery maintains optimised cell balance across every cycle, protecting both performance and longevity. A built-in touchscreen gives you real-time system visibility without needing a separate monitor or app.
At 6,000 cycles to 91% depth of discharge, this is a long-life system built to last — backed by a 6-year warranty and 10 years of customer support.
