Overview
Built for Challenging Conditions
The SGH48100T activates its heating function automatically when cell temperature falls between -13°F and 41°F (-25°C to 5°C), warming the pack to 53.6°F (12°C) so it can accept a charge safely. Once warm, the heater switches off and the battery runs as a standard 48 V LiFePO4 module.
The compact 3U pack slides into any standard 19-inch rack, ships with the cables and accessories needed for installation, and needs minimal maintenance. Its modular design lets you connect up to 32 units in parallel, so this four-battery bundle (20.48 kWh) can grow with your load.
From home energy storage to small commercial and industrial systems, the SGH48100T delivers consistent, dependable performance wherever the demand is.
