Fogstar Energy 48V Outdoor Battery System – IP56 Cabinet + 20.48kWh or 40.96kWh LiFePO4 Storage

Take your energy independence to the next level with the Fogstar Energy 48V Battery System, housed in a robust IP56-rated outdoor cabinet. Built to withstand the elements while delivering reliable, scalable power, this system is perfect for off-grid homes, solar-powered businesses, and critical backup systems.

Choose between two high-capacity configurations:

  • 1 x IP56 Outdoor Cabinet + 4 x 5.12kWh Batteries = 20.48kWh
  • 1 x IP56 Outdoor Cabinet + 8 x 5.12kWh Batteries = 40.96kWh

You can also scale your system over time by adding batteries and cabinets as needed. Connect up to 32 batteries (31 with Victron) across four cabinets for a maximum capacity of 163.84kWh.

Uncompromising Power and Capacity

Each outdoor cabinet holds up to eight Fogstar Energy 5.12kWh ESR51.2V lithium batteries, enabling substantial energy storage for homes, businesses, or remote off-grid setups. These batteries are fully compatible with leading inverters and feature integrated heating, allowing operation in temperatures as low as -20°C.

Built to Last – Indoors or Out

The cabinet is crafted from durable carbonised steel and finished to IP56 standard for full weather resistance. A slanted roof prevents rain pooling, bug-proof grating defends against pests, and a robust locking mechanism protects your system from tampering or theft.
