ESS Applications

Factory Peak Shaving

Cut demand charges by discharging during peak tariff windows.

Commercial Building Backup

Keep critical loads online through outages.

Solar + Storage

Self-consume PV, shift to evening, reduce grid draw.

Microgrid & Remote

Islanding for off-grid sites and weak grids.

Comparison: C&I ESS vs Residential & vs Container

C&I ESS vs Residential ESS

Residential ESS is a 5-20kWh wall unit for homes. C&I ESS is cabinet/container LiFePO4 (100kWh+) with higher-power PCS, fire safety and commercial metering. Choose by load and tariff profile.

Cabinet vs Container

Cabinets (100-522kWh) suit buildings and factories with space. Containers fit MWh-scale microgrids. XGW scales cabinet count to your site.

Frequently Asked Questions

What is a C&I energy storage system (ESS)?

A commercial & industrial (C&I) ESS is a rack or cabinet LiFePO4 battery system paired with a PCS/inverter for factories, commercial buildings and microgrids. It does peak shaving, demand-charge control, solar self-consumption and backup. XGW builds 100kWh/215kWh/261kWh cabinets.

Who manufactures C&I ESS in China?

XGW Digital Technology is a China-based C&I ESS manufacturer and supplier, producing 100kWh-522kWh LiFePO4 cabinets and containers for factories, commercial buildings and microgrids, with DIN rail control power and BMS monitoring. OEM/ODM since 2009.

What size commercial ESS should I choose — 100kWh, 215kWh or 261kWh?

Size to your peak-shaving or backup target: 100kWh suits small commercial buildings, 215kWh fits mid factories, 261kWh covers larger facilities and longer backup. XGW engineers the cabinet count and PCS rating to your load profile.

Can a C&I ESS pair with solar?

Yes. XGW C&I ESS integrates with rooftop/commercial PV for self-consumption, time-of-use shifting and backup — the BMS and PCS manage charge/discharge against tariff and grid signals.

What is the difference between C&I ESS and residential ESS?

Residential ESS is a small wall unit (5-20kWh) for homes. C&I ESS is cabinet/container LiFePO4 (100kWh+) with higher power PCS, fire safety and metering for commercial tariff management.

How is control power handled in an ESS rack?

DIN rail PSUs provide clean 12V/24V/48V for the BMS, cluster management and monitoring, with DC-OK signaling to the supervisor. See our DIN rail power supply.

Can ESS integrate with existing UPS?

Yes. Our UPS LiFePO4 strings drop into standard 48V-409V UPS architectures, replacing lead-acid with longer-life chemistry, and the C&I ESS can feed critical loads through outages.

What certifications apply to C&I ESS?

Typical: IEC 62619 / UL 1973 (cell & pack), IEC 62477 / UL 1741 (PCS), UN38.3 (transport), and local EMC/fire codes. XGW designs to these and supports project-specific marks.

Do you provide OEM/ODM for ESS cabinets?

Yes. XGW supports OEM/ODM from 500 units — custom capacity, enclosure, PCS and communication — samples in 3-7 days, certified production.
