Elecnova ECO E261LP 261 kWh Energy Storage System
Elecnova ECO-E261LP-2A is a liquid-cooled, all-in-one C&I energy storage system designed for businesses, industrial facilities, agriculture and renewable energy projects. The cabinet combines a 261 kWh LFP battery system with a 125 kW bidirectional PCS, BMS, EMS, cooling equipment and multi-level fire protection.
This integrated architecture turns the unit into a complete Battery Energy Storage System – BESS rather than a stand-alone battery cabinet. It reduces the number of separately installed components and provides a compact foundation for projects requiring intelligent control over energy generation, consumption and storage.
Energy management built around business demand
Industrial energy use is rarely constant. Machinery start-ups, production cycles, refrigeration, HVAC systems and EV chargers can create short periods of high demand. ECO E261LP stores energy when conditions are favourable and releases it when the facility needs additional power.
- Peak shaving helps reduce short demand peaks and the risk of exceeding contracted power limits.
- Load shifting moves grid consumption from expensive periods to lower-cost hours.
- Energy arbitrage can be supported through scheduled charging and discharging.
- Self-consumption mode prioritises the use of locally generated renewable energy.
- Open EMS integration enables connection to third-party energy management platforms through an API.
More value from solar PV
A solar installation often produces its highest output before or after the facility reaches peak demand. As a commercial solar battery storage system, ECO E261LP captures surplus PV electricity and makes it available later, when solar production falls or consumption increases.
Increasing PV self-consumption can reduce electricity imported from the grid, limit unnecessary export and improve the economic use of an existing solar installation. The system can also communicate with compatible grid-connected PV inverters, allowing storage and generation to operate as part of one energy strategy.
Energy independence and operational resilience
Geopolitical events, armed conflicts, war and economic sanctions may influence energy prices and the reliability of supply chains. A business energy storage system cannot remove these risks, but it can reduce exposure to grid electricity and make locally generated renewable energy available for longer.
When combined with a correctly designed EPS or STS cabinet, ECO E261LP can support on-grid/off-grid transfer and supply selected critical loads. The ESS cabinet must not be presented as an independent off-grid power source without this additional switching equipment and an appropriately engineered electrical system.
Liquid cooling and multi-level safety
The dedicated pack-level liquid-cooling design keeps the temperature difference between cells within 3°C. Consistent battery temperature supports balanced performance and helps protect the long-term condition of the LFP packs.
Safety measures include temperature and smoke detection, aerosol fire suppression at pack and cabinet level, pressure-relief valves and a DN65 fire-hose connection. The manufacturer’s documentation lists IEC 62619, IEC 63056, IEC 62477-1, IEC 61000-6-2/4, UL 9540A, UN 38.3 and SDS documentation.
Expandable architecture for larger projects
A single cabinet can serve a medium-sized commercial or industrial site, while larger systems can be created through parallel expansion. Grid-connected projects may use up to 12 units with a suitable POC cabinet. Configurations using an EPS or STS cabinet may connect up to 6 ESS units for on-grid/off-grid operation.
This modular approach allows the energy storage capacity to grow alongside a factory, renewable energy installation, logistics centre or charging infrastructure.
