AIO Cabinet ECO-E261LP-2A 125kW/261kWh

The Elecnova ECO-E261LP-2A is a high-performance integrated energy storage system (ESS) in a single cabinet ("all-in-one"), designed for commercial and industrial applications where both power and capacity are important. The system offers an energy capacity of approximately 261 kWh and an output power in the range of ≈ 125 kW (nominal) according to some specifications.
Important: Although the product page sometimes lists 100 kW as the “rated power,” the specification on greencorees.com lists “Rated Output Power 125 kW.”

Features & Benefits

High energy and power density : 261 kWh in a single cabinet makes it suitable for applications where space is limited but capacity is required.

Advanced cooling : Liquid cooling with cell-to-cell temperature differential < 3 °C improves reliability and longevity.

Flexible scalability : Modular and suitable for parallel configurations, allowing for expansion or power scaling.

Good grid compatibility : Low harmonic distortion, adjustable power factor and standard AC grid configuration.

Robust safety : Complies with international standards such as UN38.3, IEC62619, and UL9540A. IP55-rated enclosure and IP65 modules.

Such systems are ideal for:

Commercial or industrial buildings with a need for peak shaving or load shifting.

Renewable energy installations (solar/wind) where storage is required to accommodate production and release it later.

Situations with space limitations where a compact storage system is required.

Backup or emergency power supplies within the power class ~100-125 kW.

Aggregation or Virtual Power Plants (VPP) where multiple units are combined.
