Description

Fogstar Energy ECO 48V 16.1kWh LiFePO4 Solar Battery

The Fogstar Energy ECO 48V 16.1kWh battery is a fully assembled, commercial-grade LiFePO4 energy storage solution designed for residential and small commercial solar installations.

The 2026 model combines a large 16.1kWh capacity with integrated fire suppression, built-in battery heating and advanced cell management. The heating system allows charging at temperatures down to -10°C, making the battery suitable for garages, outbuildings and other colder installation environments.

Built using 3.2V 314Ah Grade A cells in a 1P16S configuration, the battery is managed by a 200A BMS together with a JK 2A Active Balancer for stable performance and long-term cell health.

CAN and RS485 communication provide compatibility with a wide range of popular inverter systems, including Victron, Sunsynk, Solis, LuxPower and Voltacon.
