Energy Storage Solutions for Commercial, Industrial & Solar Buyers
XGW Digital Technology is a China-based commercial and industrial energy storage system (C&I ESS) manufacturer and lithium battery OEM/ODM, building rack and containerized LiFePO4 ESS with PCS and BMS for solar self-consumption, peak shaving and backup. Energy storage is no longer a single product — it is a site design. We size the battery, inverter and controls to the tariff, load and PV you actually have, then certify and ship it as one package.
Who We Build ESS For
Solar EPCs & Installers
Pairing PV with storage is where the margin is. As a solar EPC battery storage partner, XGW supplies rack and containerized LiFePO4 ESS with PCS, so you deliver self-consumption and time-of-use arbitrage instead of exporting cheap midday solar.
Commercial Building & Facility Owners
Offices, warehouses and retail sites bleed cash on demand charges. A commercial energy storage system from XGW clips peak demand and shifts load to off-peak tariffs, paying back through the utility bill without touching operations.
Industrial & Manufacturing Plants
Factories need firm power and predictable cost. An industrial battery energy storage system backs critical lines, rides through outages and smooths the demand spikes that trigger penalty tariffs — built to run in harsh plant environments.
Telecom & Data Center Operators
Sites already on 48V backup need to scale to hours and add solar. XGW bridges telecom/UPS lithium with larger ESS, giving operators a microgrid battery storage path from BTS backup to site-level resilience.
Microgrid & Remote / Island Sites
Off-grid communities, mines and islands run on diesel or weak grids. A microgrid battery storage manufacturer like XGW delivers containerized ESS that stacks with PV and genset to cut fuel and stabilize frequency.
Farms & EV-Charging Operators
Agriculture and charging hubs share one pain: spiky, site-limited demand. Solar battery storage for farms and EV charging station battery storage from XGW absorb PV and discharge during peak draw, avoiding costly grid upgrades.
What the ESS Build Includes
Rack (indoor) or containerized (outdoor) LiFePO4 battery with module-level BMS
PCS inverter sized to load — hybrid, grid-forming or backup modes
EMS for peak shaving, self-consumption, TOU arbitrage and backup logic
CAN/RS485/SNMP communication for remote monitoring and NOC integration
Fire suppression, thermal management and IP-rated enclosure per site
UN38.3 / IEC 62619 / UL 1973 design basis, CE and market marks supported
What is a commercial and industrial energy storage system (C&I ESS)?
A C&I ESS is a rack or cabinet LiFePO4 battery system (typically 30kWh to several MWh) paired with a PCS inverter that stores energy from the grid or solar and discharges it for peak shaving, demand-charge reduction, backup and self-consumption. XGW builds rack and containerized C&I ESS as OEM/ODM.
Who manufactures C&I energy storage systems in China?
XGW Digital Technology is a China-based commercial and industrial energy storage system (C&I ESS) manufacturer and lithium battery OEM/ODM, producing rack and containerized LiFePO4 ESS with PCS and BMS, UN38.3 / IEC / CE certified, serving 50+ countries since 2009.
How does battery storage reduce electricity cost for a factory?
By charging during off-peak tariffs and discharging during peak windows (peak shaving) and by clipping demand-charge spikes, a C&I ESS cuts a factory's demand charges and energy spend without changing production. Solar self-consumption adds further savings by storing PV for later use.
Can XGW customize an ESS to my site?
Yes. XGW provides OEM/ODM ESS — custom capacity, PCS power, enclosure (indoor rack or outdoor container) and communication protocol — with engineering support, prototype testing and certified production. See our custom ESS page.
