Battery
LiFePO4 rack or cabinet modules — long cycle life, wide operating range, no maintenance.
Commercial & Industrial Battery Energy Storage Systems
XGW C&I ESS pairs LiFePO4 battery racks or all-in-one cabinets with a PCS inverter and EMS for peak shaving, solar self-consumption, demand-charge reduction and backup. We size power and energy to your tariff and load, then certify and ship as one package. The line covers four models — from the 125kW / 261kWh all-in-one cabinet up to a 500kW / 1028kWh BESS — for factories, commercial buildings and microgrids.

Four commercial & industrial energy storage models share the same LiFePO4 chemistry, BMS/EMS platform and safety architecture. Pick the power and energy that match your site — every model has its specification sheet below.
| Model | Rated Power | Energy | Typical Use |
|---|---|---|---|
| 125kW / 261kWh All-in-One (flagship) | 125 kW | 261 kWh | Peak shaving and backup for factories, commercial buildings, microgrids |
| 125kW / 241kWh HV C&I ESS | 125 kW | 241 kWh | High-voltage architecture for commercial and industrial sites |
| 100kW / 215kWh All-in-One C&I ESS | 100 kW | 215 kWh | Compact footprint for demand-charge reduction and solar self-consumption |
| 500kW / 1028kWh All-in-One C&I ESS | 500 kW | 1028 kWh | Larger industrial sites and C&I microgrids |
Flagship Model: 125kW / 261kWh All-in-One C&I ESS
The XGW 125kW 261kWh energy storage system puts a 125kW PCS and a 261kWh LiFePO4 battery in one outdoor cabinet, with integrated thermal management, EMS and fire suppression in a single footprint. At roughly two hours of usable storage it suits peak shaving, demand-charge reduction and backup for commercial buildings, factories and microgrids. Cabinets parallel for larger sites, and the EMS handles grid-tie, off-grid and hybrid modes.

What's Inside a Complete BESS
PCS (Inverter)
Power Conversion System converts DC battery power to grid-grade AC; the standard cabinet uses a 125kW PCS.
EMS
Energy Management System runs peak shaving, self-consumption and time-of-use arbitrage across grid-tie / off-grid / hybrid modes.
Thermal & Safety
Intelligent air-cooled thermal management; liquid-cooled option for high-density sites, with integrated fire suppression.

Typical Applications
Factories & industrial sites
Clip peak demand and shift load to off-peak tariffs without changing production. XGW pairs the cabinet with a PCS sized to your peak load.
Commercial buildings
Reduce demand charges and provide backup for elevators, lighting and critical loads. The IP54 outdoor cabinet installs beside the building with minimal footprint.
C&I microgrids
Off-grid and hybrid operation with PV and genset, managed by the EMS. Cabinets parallel as the site load grows.
Solar + storage farms
Store PV for evening self-consumption and TOU arbitrage. See ESS for Solar Self-Consumption.
Tropical & harsh sites
Built for 50°C Gulf ambient resilience: intelligent air-cooled thermal management keeps LiFePO4 cells in range through Middle East summers, with a liquid-cooled option for higher-density sites.
Backup for critical loads
Seamless handover from grid to battery for telecom, data-center and process loads when the grid drops.

Frequently Asked Questions
How do I determine the required power and energy capacity for a C&I ESS?
Power (kW) is set by the load you want to support or the peak you want to clip; energy (kWh) is set by how many hours of that load you need to cover. A 125kW / 261kWh cabinet delivers roughly two hours at full power, or longer at partial load. Send us your peak demand profile and target hours and we size the system and confirm how many cabinets to parallel.
What is included in a complete BESS?
A complete battery energy storage system pairs the LiFePO4 battery with a PCS inverter (AC-DC / DC-AC), an EMS controller for grid-tie / off-grid / hybrid operation, thermal management, fire suppression and a monitoring gateway (CAN / RS485, SNMP optional). XGW ships the 125kW / 261kWh unit as an integrated cabinet so these are pre-matched.
Which PCS, BMS and EMS options are available?
The standard cabinet uses a 125kW PCS with integrated BMS and EMS supporting grid-tie, off-grid and hybrid modes. For larger or custom projects we configure higher-power PCS, redundant BMS and EMS features such as demand-charge control, self-consumption and time-of-use arbitrage. Tell us the grid code and use case and we confirm the configuration.
What information is needed for a preliminary system quotation?
Share your site country, grid type (grid-tie / off-grid / hybrid), target power (kW), target energy (kWh), application (peak shaving, backup, solar self-consumption) and any cooling or PCS/EMS preference. With those we return a configuration, lead time and budget-range quote within 24 hours.
