PLUG-AND-PLAY ENERGY STORAGE SOLUTION

PLUG-AND-PLAY ENERGY STORAGE SOLUTION

BENEFITS AT A GLANCE PLUG-AND-PLAY. ALL IN ONE The Y.Cube is a ready-to-install storage system, with all components inside a single enclosure. This off-theshelf solution comprises batteries, inverter, HVAC and auxiliary components, all tested and pre-assembled by Younicos experts, and seamlessly operated by the smartest software on the market. MODULAR AND SCALABLE Thanks to its modular design, the Y.Cube is easily configurable for different system sizes. A single Y.Cube is available as a 250 kva or 500 kva module, or several enclosures can be clustered to build multi-megawatt systems. Thus Y.Cube can grow with your needs, giving your business complete flexibility! CUSTOMISED TO YOUR NEEDS Younicos experts work with you to determine the best size and configuration for your system based on the applications you require. We will also help you select the most suitable battery technology and manufacturer based on our experience from more than 40,000 test cycles at our battery labs. POWERED BY Y.Q Y.Q operates all system components safely, quickly and efficiently to handle all types of storage applications while ensuring a long asset lifetime. In fact, we have received up to 20-year performance warranties from leading battery manufacturers on the strength of Y.Q. COST EFFICIENCY CERTIFIED QUALITY The Y.Cube combines the highest performance with cost efficiency. The compact enclosures can easily be installed with a forklift instead of an on-site crane and have less parasitic losses and slower battery degradation thanks to superior thermal management. Our solutions have been tested and approved internationally. The Y.Cube proudly carries the following certifications: UL 1741, IEEE 1547, IEC 62477-1, CSA C22.2 #107.1, G59/3, IEC 61000-6-2, 4 and FCC part 15 Class A. CE marked.

Y.CUBE CONTAINERISED ENERGY STORAGE The Y.Cube is an all-in-one system within a single enclosure that houses the Y.Converters, chosen DC battery blocks, HVAC and auxiliary components, with operation and performance managed by Y.Q, the Younicos software platform. Y.Q software platform Our intelligent software enables faster response times, response accuracy and real-time energy management to optimise battery performance. It determines automatically which function is most valuable according to the grid and market conditions and deploys real-time responses within 20 milliseconds. DC battery of your choice The Y.Cube accommodates multiple battery technologies so that you can choose the best chemistry for the required power/energy ratio. Battery enclosure Its economic footprint allows for space-saving and easy installation, even at the most remote project sites. Best-in-class converter technology The bidirectional Y.Converter with embedded Younicos controls allows direct communication between PCS and battery racks. This approach minimises usable capacity losses and mitigates fault current risk. Its superior grid-forming capabilities are key for weak grid environments. Thermal management system The Y.Cube manages battery rack cooling within more consistent limits, resulting in less parasitic loss and slower battery degradation. Fire suppression The fire suppression tank is filled with a clean agent, smoke detection units, dispersal nozzles, and a gas actuator. Modular enclosures provide increased segmentation of the system.

PLUG-AND-PLAY OUR 360-DEGREE APPROACH Younicos is your storage project partner from launch to commissioning. We carefully consider your business needs, factor in region-specific market and regulatory requirements, and apply the expertise we ve gained from 200 megawatts of storage projects worldwide to make yours a success. PLANNING SYSTEM DESIGN AND ENGINEERING We don t simply sell you a battery we configure the most reliable and efficient energy storage product for your specific requirements. We always plan with the future in mind so that it can accommodate your needs today and tomorrow, as new storage applications emerge. DEPLOYMENT PROCUREMENT Younicos is technology-agnostic so you can always be sure that we ll choose the best components for your system. We also handle all ordering, scheduling and tracking to ensure timely delivery to the project site. COMMISSIONING Batteries, power conversion technology, thermal management and fire suppression are validated for operational acceptance and guaranteed capabilities. Simultaneously, we commission the control systems. O&M SERVICE From our 24/7 operations centre, experienced Younicos operators remotely monitor and troubleshoot all our project deployments around the clock. We re committed to ensuring that your energy storage system operates safely, reliably and at the highest availability to maximise your return on investment.

CONFIGURE IT ONE SOLUTION FOR ALL YOUR REQUIREMENTS The Y.Cube uses a modular approach. Single units can be easily combined to deliver the power and energy capacity required for your business, covering a wide range of applications. The system can cover a variety of applications from a few hundred kw up to multi-mw power output, and from minutes up to hours in duration. Even better: if your requirements change in the future, the Y.Cube lets you add capacity and power as needed. This gives you complete flexibility and enables you to plan for your future business needs. PRODUCT MAX.

Battery storage smooths the PV plant and strengthens the grid by providing critical system services to buffer the impact of fluctuating power demand and supply. Dispatchable PV Large-scale PV plants receive lower payments for output during the sunniest hours. Y.Cube shifts PV generation into the evening peak and can also be dispatched to offset rapid output changes in PV generation caused by shading and add reliability to grid operations. Peak load reduction C&I customers, for example in California and New York, face increased charges for consumption during peak hours. Battery storage reduces peak demand and enables customers to optimise use of onsite solar and other energy management programs.
