Follow our engineers to learn about ESS-GRID FlexiO 1MWH/500kwh

Compact, convenient outdoor commercial energy storage system

The 500kWh/1MWh outdoor cabinet-style photovoltaic energy storage system integrates energy storage batteries, PCS (Power Conversion Systems), power distribution, temperature control, fire protection, water detection sensors, and monitoring and communication functions.

This system offers grid voltage regulation, three-phase imbalance control, and harmonic management, enabling comprehensive monitoring and risk management to significantly enhance power quality.

Its standardized structural design supports flexible integration of photovoltaic charging modules, off-grid switching modules, power frequency transformers, and other components. The system is further customized based on specific energy requirements and industrial or commercial load demands, including BMS and EMS structural, air duct, and communication protocol configurations.

With scalable capacity, this system supports both AC-side and DC-side parallel options, allowing long-distance parallel operation and off-grid switching of multiple units without communication lines. Tailored energy management strategies enable remote upgrades, enhancing operational flexibility and control.

AC side expansion provides more power

ESS-GRID FlexiO 4

Supports parallel connection of up to two FlexiO series units, enabling straightforward upgrades from 500kW to 1MW of storage capacity. It can store up to 3.8MWh of energy, sufficient to supply power for approximately 3,600 homes for one hour.

● Photovoltaic + Energy Storage + Diesel Generation

A hybrid energy solution combining photovoltaic power (DC), energy storage (AC/DC), and diesel generators (typically supplying AC power).

● High Reliability and Long Lifespan

Backed by a 10-year battery warranty, this system uses advanced LFP module patented technology, offering up to 6,000 cycles and equipped with an intelligent temperature control system for both hot and cold conditions.

● Flexible and Scalable Design

Each battery cabinet offers 241kWh, with options for scalable expansion as needed, supporting both AC and DC configurations.

● High Security with Multi-Layered Protection

Equipped with a 3-tier fire protection system and an advanced BMS intelligent management center. This system includes leading battery management technology, integrating both active and passive fire safety features, with PACK-level, cluster-level, and dual-room fire safeguards.

● Adaptive System Control

Optimized with a preset logic algorithm, this setup handles DC coupling autonomously, reducing reliance on the EMS energy management system and thereby cutting operational costs.

● 3D Visualization Technology

A 3D interface displays real-time module status, enabling an intuitive and interactive approach to monitoring and control.
