Fogstar Energy IP65-Rated 10kWh 51.2V Modular Battery Stack
This Fogstar Energy IP65-rated 10kWh 51.2V modular battery stack is a wall-mountable LiFePO4 storage unit designed for homes, small commercial sites and logistics operations that need dependable power in tough conditions. The fully sealed IP65 housing, integrated fire suppression and low-temperature heating make it well-suited to plant rooms, warehouses, workshops and sheltered external locations where safety and reliability are critical.
With 200Ah capacity and up to 200A discharge current, it pairs comfortably with modern hybrid and off-grid inverters for applications such as backup power for offices or depots, EV charger load support, small warehouses, telecoms cabins and remote monitoring sites. Parallel expansion up to 16 units allows you to build multi‑battery stacks for higher capacity systems as site demand grows.
