Product Description

Product Description

The ESA261 is an all-in-one outdoor energy storage system for commercial and industrial applications, delivering 125 kW rated power and 261.25 kWh usable energy. It integrates LFP batteries, a power conversion system (PCS), battery management system (BMS), energy management system (EMS), thermal management and fire protection in one cabinet.

Designed for peak shaving, load shifting and solar-storage coordination, the AC-coupled system helps businesses manage electricity demand and make better use of on-site renewable energy. Its five-pack battery configuration and 1.47 m² cabinet footprint support compact installation.

Two models are available: the G10 features liquid-cooled battery packs and an air-cooled PCS, while the G11 features intelligent liquid cooling. Both provide 400 V three-phase output at 50 Hz and IP54 enclosure protection.

Wi-Fi, 4G, LAN and Bluetooth connectivity support monitoring and energy management. Integrated fire protection includes pack- and cluster-level aerosol suppression, smoke and temperature detection, and a reserved water fire-fighting interface. Additional safety options are available to suit project requirements.

Company Profile

Since 2018, we have focused on turning clean energy technologies into practical systems for real-world applications. Energy storage is at the core of our business, supported by a broader portfolio covering solar-integrated buildings, vehicle-mounted solar systems, heat pumps, and solar lighting.

Our energy storage portfolio includes residential and commercial & industrial systems designed for solar self-consumption, backup power, peak-load management, and greater energy independence. Rather than offering a one-size-fits-all product, we consider the customer's load profile, installation environment, backup requirements, and future expansion plans to identify a suitable system configuration.

Our experience across buildings, transportation, heating, and lighting gives us a wider perspective on how renewable energy can be integrated into everyday life and business operations. This application-driven approach allows us to focus on both product performance and the way each system will be used.

We work with distributors, installers, project developers, and energy professionals in international markets. Through clear technical communication and a practical understanding of local requirements, we aim to help our partners deliver dependable clean energy projects and build long-term value together.
