500kW / 1MWh Microgrid
Industrial Battery Energy Storage System
ESS-GRID FlexiO is an air-cooled industrial/commercial battery solution in the form of a split PCS and battery cabinet with 1+N scalability, combining solar photovoltaic, diesel power generation, grid and utility power. It is suitable for use in microgrids, in rural areas, in remote areas, or in large-scale manufacturing and farms, as well as for charging stations for electric vehicles.
500kW/1MWh Turnkey Commercial and Industrial Energy Storage System
The FlexiO series is a highly integrated battery energy storage system (BESS) designed to optimize performance and reduce costs for stationary commercial and industrial energy storage applications.
● Full Scenario Solutions
● Full Ecosystem Creation
● Lower Costs, Increased Reliability
Why ESS-GRID FlexiO Series?
● PV+ ENERGY STORAGE + DIESEL POWER
A hybrid energy system that combines photovoltaic power generation (DC), an energy storage system (AC / DC), and a diesel generator (which typically provides AC power).
● HIGH RELIABILITY, HIGH LIFESPAN
10-year battery warranty, advanced LFP module patented technology, cycle life up to 6000 times, intelligent temperature control program to challenge the challenge of cold and heat.
● MORE FLEXIBLE, HIGH SCALABILITY
Single battery cabinet 241kWh, expandable on demand, supports AC expansion and DC expansion.
● HIGH SECURITY, MULTI-LAYER PROTECTION
3 level fire protection architecture + BMS intelligent management center (the world's leading battery management technology, including active and passive fire protection dual integration, the product setup has a PACK level fire protection, cluster level fire protection, dual-compartment level fire protection).
● ADAPTIVE CONTROL
The system utilizes pre-set logic algorithms to manage DC coupling, effectively reducing dependence on the EMS energy management system and thus reducing overall cost of use.
● 3D VISUALIZATION TECHNOLOGY
The display provides an intuitive and interactive monitoring and control experience, as it presents the real-time status of each module in a stereoscopic three-dimensional manner.
DC-side Expansion For Longer Backup Time
5 ~ 8 ESS-BATT 241C, coverage 2-4 hours of power backup hours
AC-side Expansion Provides More Power
Easily upgradable from 500kW to 1MW of energy storage, storing up to 3.8MWh of energy, enough to power an average 3,600 homes for one hour.
