Product Description

High Energy Efficiency and Intelligent Management

The SET-BLW series outdoor energy storage cabinets integrate energy storage batteries, modular PCS, energy management monitoring systems, power distribution systems, environmental control systems, and fire suppression systems. Featuring a modular PCS design for ease of maintenance and expansion, the outdoor cabinets employ a front-access maintenance structure to minimise footprint and maintenance aisles. They offer characteristics including safety and reliability, rapid deployment, low cost, high energy efficiency, and intelligent management.

Specification

Applications

1. Off-grid or weak grid areas: Stable, economical power supply with off-grid or hybrid grid-tied operation
2. Standby and emergency power for critical facilities: Exceptionally high supply reliability
3. Commercial and industrial applications: Reduced electricity costs and guaranteed production continuity

Key Configurations

Peak Shaving and Valley Filling: During off-peak tariff periods, the energy storage cabinet automatically charges to full capacity and remains on standby. During peak tariff periods, the cabinet automatically discharges to capitalise on price differentials, enhancing the economic efficiency of the photovoltaic-storage charging system.
Integrated Energy Storage Mode: Real-time monitoring of local load power prioritises on-site photovoltaic self-consumption, with surplus power stored. Should photovoltaic output fall short of local demand, stored battery energy is deployed as the primary source.

Environmental control systems

The energy storage system is equipped with environmental control units such as smoke detectors, flood sensors, door magnetic sensors and fire protection, which can fully control the system operation status. Schematic diagram of environmental control system.
