BESS BSI

Description

Battery Storage Kit Indoor (BSI) is a fully pre-configured, indoor lithium-ion energy storage solution designed for commercial and industrial applications requiring reliable, scalable, and high-performance battery storage. The BSI combines proven battery technology with integrated power electronics to deliver a turnkey solution with minimal installation and commissioning effort.

The system integrates a 50 kW or 88 kW battery inverter with an advanced Energy Management System (EMS), enabling intelligent control for peak shaving, time-of-use optimisation, self-consumption maximisation, and energy trading. Modular LFP battery racks allow capacity expansion from approximately 100 kWh up to 872 kWh, making the BSI adaptable to evolving energy demands.

Designed for indoor installation, the BSI is well suited to commercial buildings, industrial facilities, agricultural sites, and urban infrastructure projects. It is also ideal as buffer storage for EV fast-charging stations, increasing usable output while reducing stress on the grid connection. With high safety standards, extensive international certifications, and long-term warranties, the BSI delivers dependable performance throughout its lifecycle.
