C & I storage system CA coupling SAJ 125KW / 261KWH CM2-125K-261 | EMS intelligence and liquid refrigeration

SAJ CM2-125K-261: BESS storage of 261KWh with AC coupling, advanced liquid cooling and AL-EMS software for maximum economic return

The optimization of operating and electrical costs in large factories, logistics warehouses or shopping centers requires mass storage infrastructures capable of managing energy flows with total security. The compact container CM2 AC Coupleing Storage 125KW + 261KWh (technical reference Cm2-125k-261) Represents the cusp of engineering SAJ and its Elekeeper division, offering a power intelligent power in alternating current (CA) designed to integrate flexibly into existing photovoltaic plants or directly connected to the industrial distribution network.

Flexible CA coupling, liquid thermal efficiency and top life cycle

Unlike traditional teams in continuous current, this robust system is interconnected by alternating current coupling (CA), which drastically facilitates technical reconversion processes in industries that already have inverters solar network installed from any manufacturer. The system releases a continuous nominal power of 125 kW and protected a total capacity of 261.1 kwh through Premium Industrial Lithium Cells.

To completely brake the chemical wear of its compounds and ensure a round-trip (RTE) performance greater than 90%, the CM2 cabinet discards the use of conventional fans and displays a comprehensive system of liquid Refrigeration (Liquid Cooling) for the battery bank, in combination with an independent air conditioning system for the module inverter (PC). Thanks to this meticulous thermal management, cells achieve exceptional longevity of greater than or equal to 8000 life-life cycles before reducing its capacity at 70% EOL.

Security E2E Secfort Certified UL9540A, EMS Management and IP54 Immunity

The tranquility of the business is assured through the 5-layer defense architecture E2E SECFORT, an international standard endorsed by the demanding certification Ul9540a against risks of thermal propagation. The inner cabinet includes preventive digital monitoring in the cloud (Cloud bms), Monitoring electrical distribution and an automated system of suppression and extinction of fires. The algorithmic brain of the whole is governed by a eMS intelligent system driven by IA, which is linked in real time with the regulated electricity market to apply automated rate arbitration strategies (TOU), Consumer Peak Cutting (peak Shaving) and support for virtual power plants (VPP).

All this technology is compacted in a high density outer container with an insulation index IP54 for the general cabinet and IP65 for the PC block, being immune to atmospheres with high pollution or humidity. To suitably complement this deployment of deep cycle storage, we invite you to consult the available solutions in our specialized menu of batteries and high power modules.

Frequently Asked Questions (FAQ)

1. What real advantages does the CA coupling offer the system SAJ Cm2 versus one in cc? AC coupling (CA) provides superior flexibility in commercial and industrial modernization projects. When connecting directly to the company's alternate distribution general, it does not depend on the brand nor of the voltage of the inverter photovoltaic that is already installed. This allows to add the 261 kWh of storage capacity independently of the network, facilitating a clean extension without altering the wiring of the series of the solar existing.
2. Why is liquid cooling as important in the cells of this industrial cabinet? In large density industrial systems such as CM2, the continuous flow of high current heats the accumulators. The liquid cooling system of SAJ circular refrigerant circulates directly by each of the battery packs, dissipating the heat in a much more uniform and efficient way than conventional air conditioning. This avoids hot spots, guarantees that the cells always work at its ideal temperature and lengthen the life of the equipment until reaching or exceeding 8000 cycles of operation.
3. How does the artificial intelligence of EMS integrated help reduce the electricity invoice of a company? Integrated EMS intelligent software monitors factory consumption patterns in real time and connects with the electric market. In this way, automatically run the battery charge at the lowest cost hours (valley hours) and download the 125 kW power at times with more expensive rates or when the factory experiences very high consumer peaks, reducing charges per share of contracted power (peak Shaving).
4. What kind of fire safety approvals do you have the CM2-125K-261 model? This storage system has been developed under the strictest international security criteria of the Sector Bess, with the prestigious certification Ul9540a. This certification verifies through destructive laboratory tests that the design of the cells and the structure of the cabinet completely prevent the spread of fire or thermal packaging between modules, guaranteeing an absolute protection of the industrial buildings or commercial buildings where it is located.
