125 kW / 261 kWh

261 kWh and 125 kW in a 1.35 m² cabinet. Liquid cooling, three-level fire protection and remote control from the cloud.

Sized at your premises

For businesses and industry, one of our technicians visits your premises to define the right capacity and power, taking your back-up needs into account. In coordination with your own in-house technicians, we choose the best position, indoor or outdoor, weighing installation costs and the distance to the main electrical board.

The app on your phone REAL TIME

We install the app on your phone: see in real time when the battery charges and discharges, the energy and money you save, your consumption and the system status, wherever you are.

Important: stable wifi

The battery's AI system connects via wifi to receive energy prices and apply its savings strategy. A stable wifi connection where the battery is installed is essential.

Description

Liquid-cooled integrated storage cabinet

The M125G261A is a grid-connected storage system for business and industry. It integrates LiFePO₄ batteries, BMS, power conversion system (PCS), energy management system (EMS), fire protection and liquid cooling in a single cabinet 2.17 m high.

Its converter uses third-generation silicon carbide semiconductors, and smart liquid cooling cuts the system's own consumption. More usable energy and a life of 8,000 cycles or more.

Safety works on three levels: monitoring of short circuits, overcurrents, overvoltages and temperatures; fire protection at module and cluster level plus water-based suppression; and explosion-proof design at module and cabinet level. With the EMS and cloud platform you monitor, configure and update it remotely, and see what it earns.

We do not guarantee any specific percentage of savings. The savings figures we mention are average savings based on what our customers with this installation are achieving. Every customer has their own consumption curve and contracted power, depending on their tariff and electricity supplier, which our AI battery learns during the first one or two weeks and then uses to apply the best charging and discharging strategy, and with it the greatest possible savings in each case.
