Industrial Energy Storage Solutions

Energy Storage Systems Designed Around Your Application

Industrial energy solutions should be designed around the actual operating profile of the facility rather than a fixed battery size.

GSL Energy works with project partners to configure battery systems according to power demand, energy capacity, operating hours, installation environment and integration requirements.

Peak Shaving

Reduce the impact of high-power demand periods by supplying part of the facility's load from stored energy.

Load Shifting

Store energy when it is economically or operationally advantageous and discharge it during higher-value periods.

Renewable Energy Integration

Increase the utilization of solar and other renewable generation by storing excess electricity for later consumption.

Backup Power

Provide battery-backed energy for critical loads where power continuity is important.

Microgrid Energy Storage

Integrate battery storage with solar generation, inverters, and energy management systems to support resilient distributed energy systems.

EV Charging

Use BESS to supplement grid capacity and manage power demand for high-power EV charging infrastructure.

Frequently Asked Questions

What does a lithium battery manufacturer do?

A lithium battery manufacturer develops and produces battery systems rather than simply reselling products from another supplier. Manufacturing capabilities may include battery pack assembly, BMS integration, testing, and system integration.

What is the difference between a 100kW battery and a 500kWh battery?

kW describes power — how much energy the system can deliver at a given moment. kWh describes energy capacity — how much energy the battery can store. A BESS project normally requires both a power rating and an energy capacity.

What is a 500kWh BESS used for?

A 500kWh BESS can be used for commercial and industrial energy storage, peak shaving, solar energy shifting, backup power, microgrids, and EV charging support. The required power rating depends on the application.

Are LiFePO4 batteries suitable for solar energy storage?

Yes. Lithium iron phosphate (LiFePO4) chemistry is widely used in stationary energy storage because it combines cycle life, thermal stability, and energy density.

Can GSL Energy supply 100kW battery storage systems?

Yes. GSL Energy can configure commercial and industrial BESS solutions around a 100kW-class power requirement. Final battery capacity depends on the site's load profile, required operating duration, and system architecture.

Can a 500kWh battery system be customized?

Yes. BESS configurations can be adapted according to the required power, energy capacity, voltage architecture, installation environment, inverter configuration, and project requirements.

Does GSL Energy provide OEM and ODM services?

Yes. GSL Energy provides OEM, ODM, and OBM cooperation for qualified B2B customers, depending on product type, configuration, and project requirements.

Can GSL Energy support European BESS projects?

Yes. GSL Energy supplies lithium battery and BESS solutions for international markets and provides technical support for system configuration, documentation, installation, and project deployment.

What certifications are available?

Certification depends on the specific battery or BESS model. Depending on the product, certifications and standards may include CE, IEC 62619, UN38.3, UL9540, UL9540A, UL1973, VDE-AR-N 4105, and CEI 0-21.
