Hybrid Solar System with Battery & Commercial BESS Manufacturer | Why Choose ONESUN?

As global electricity demand continues to rise and renewable energy becomes increasingly important, Hybrid Solar Systems with Battery Storage and Battery Energy Storage Systems (BESS) are becoming essential solutions for homes, factories, commercial buildings, industrial parks, microgrids, and renewable energy projects.

From a 50kWh battery energy storage system to a 100kWh commercial ESS, 215kWh BESS, 500kWh BESS, 1MWh battery storage system, and 2MWh commercial energy storage system, ONESUN provides scalable energy storage solutions designed for different power requirements and application scenarios.

Commercial BESS Manufacturer

As an experienced Chinese lithium battery manufacturer, ONESUN combines battery technology, BMS, inverter integration, system engineering, and OEM/ODM manufacturing to provide global customers with complete energy storage solutions.

Hybrid Solar System with Battery: From Solar Generation to Energy Independence

A hybrid solar system with battery storage combines solar PV generation, battery storage, and an intelligent inverter to create a flexible energy management platform.

During the daytime, solar panels can supply electricity to loads while charging the battery. When solar generation is insufficient, the stored energy can be discharged to support the load. Depending on system configuration, the battery can also provide backup power during grid outages.

For residential applications, ONESUN provides integrated energy storage solutions designed to simplify installation and operation. For commercial and industrial customers, larger BESS systems can support peak shaving, backup power, solar self-consumption, energy management, and microgrid applications.

ONESUN's product portfolio covers everything from integrated energy storage systems to large-scale commercial and industrial BESS solutions.

50kWh Battery Energy Storage System & 100kWh Commercial ESS

For small and medium-sized commercial applications, a 50kWh battery energy storage system or 100kWh commercial ESS can provide a practical balance between investment, capacity, and scalability.

Typical applications include:

Small factories and workshops

Retail stores and supermarkets

Office buildings

Farms and agricultural facilities

Telecom and backup power systems

Solar self-consumption projects

Microgrid applications

ONESUN's Smart BESS Cabinet product family includes 60kWh and 100kWh configurations, with modular architecture designed for flexible deployment and easier maintenance.

This modular approach allows customers to start with an appropriate capacity and expand their energy storage system as electricity demand increases.

215kWh BESS: A Smart Solution for C&I Energy Storage

For larger commercial and industrial applications, the 215kWh BESS system has become an attractive configuration.

ONESUN's 100kW Smart BESS Cabinet is available in approximately 215kWh–241kWh configurations. The system integrates lithium battery packs, PCS, EMS, and multiple protection functions into a highly integrated cabinet.

This type of BESS can help factories and commercial facilities manage energy more intelligently, including:

Peak Shaving: Store electricity and discharge it during high-demand periods.

Solar Energy Storage: Store excess solar generation and use it when solar production decreases.

Backup Power: Provide additional power resilience for critical loads.

Energy Management: Work with EMS platforms to monitor and optimize energy consumption.

500kWh BESS, 1MWh and 2MWh Commercial Energy Storage

When energy requirements become larger, modular BESS architecture allows multiple battery cabinets or containerized systems to work together.

A 500kWh BESS can be suitable for medium-scale commercial and industrial projects, while 1MWh battery storage systems and 2MWh commercial energy storage systems can support larger factories, industrial parks, renewable energy projects, microgrids, and high-demand facilities.

For even larger projects, containerized energy storage provides a practical way to integrate battery systems, PCS, EMS, thermal management, fire protection, and electrical protection within a standardized deployment platform.

ONESUN's product portfolio already includes containerized ESS solutions, including 20ft/40ft container systems with multi-MWh capacity.

Why Choose ONESUN?

1. Experienced Lithium Battery Manufacturer

ONESUN was established in 2014 and has more than a decade of experience in lithium battery and energy storage manufacturing.

The company focuses on LiFePO4 battery technology and energy storage applications, providing solutions for residential, commercial, industrial, telecom, and renewable energy projects.

2. Strong Battery + BMS + Inverter Integration

One of ONESUN's major advantages is its integrated manufacturing capability.

ONESUN operates battery and inverter manufacturing facilities and has BMS and PCBA production capabilities. This helps solve battery-inverter communication and system integration challenges that can occur when components come from different suppliers.

3. OEM & ODM Battery Pack Solutions

Different markets require different battery capacities, voltages, communication protocols, enclosures, cooling solutions, certifications, and branding.

ONESUN therefore provides both OEM and ODM battery solutions.

For OEM projects, customers can provide their own specifications, brand requirements, and product designs.

For ODM projects, ONESUN can support product development from technical architecture and battery pack design to BMS configuration, prototype development, testing, and mass production.

This makes ONESUN a valuable manufacturing partner for distributors, EPC companies, energy storage brands, and system integrators looking to launch customized BESS products.
