OUR PLUG-AND-PLAY ENERGY STORAGE SOLUTION

OUR PLUG-AND-PLAY ENERGY STORAGE SOLUTION

BENEFITS AT A GLANCE PLUG-AND-PLAY. ALL IN ONE. MODULAR AND SCALABLE. Y.Cube is a ready-to-install storage system with all components inside a single enclosure. This offthe-shelf solution comprises batteries, inverter, HVAC and auxiliary components, all tested and pre-assembled by Younicos experts. All system components are operated safely, fast and efficiently by Y.Q, the smartest software on the market. 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! CUSTOMIZED TO YOUR NEEDS. HIGHEST DEGREE OF EFFICIENCY. 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. The Y.Cube combines highest performance with cost efficiency. The compact enclosure can easily be installed with a forklift instead of an on-site crane and shows less parasitic losses and slower battery degradation due to its superior thermal management.

MODULAR DESIGN: THE HIGHEST DEGREE OF FLEXIBILITY The Y.Cube is an all-in-one system within a single enclosure which houses the Y.Converters, chosen DC battery blocks, HVAC and auxiliary components, with operation and performance managed by Younicos Controls. Y.CONVERTER 250 The bidirectional Y.Converter with embedded Younicos controls allows direct communication between PCS and battery racks. This approach minimizes usable capacity losses and mitigates fault current risk. Its superior grid-forming capabilities are key for weak grid environments. Y.Q CONTROL PLATFORM Our intelligent software enables advanced response times, response accuracy and real-time energy management to optimize battery performance. It determines automatically which function is most valuable according to the grid and market conditions and deploy real-time responses within 35 milliseconds. 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 an agent gas, smoke detection units, dispersal nozzles, and a gas actuator. Modular enclosures provide increased segmentation of the system. BATTERY BLOCK The Y.Cube accommodates multiple battery technologies so that you can choose the best chemistry for the required power/energy ratio. YOUNICOS BATTERY ENCLOSURE Its economic footprint allows for spacesaving and easy installation even at the most remote project sites.

SCALE IT: FROM 250 KW UNITS TO MULTI-MEGAWATT PARKS A system built for your requirements now and in the future! The Y.Cube is available with either 250 kva or 500 kva capacity. Single units can be easily combined together to deliver the power and energy capacity required for your business. The system can cover a wide range 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. That gives you complete flexibility and enables you to plan for your future business needs.

TYPICAL APPLICATIONS Island Grids Ramp Rate Control Island grids like Puerto Rico cannot absorb large fluctuations of renewable generation; battery storage smooths the PV plant. Cloudy day "Smoothed" PV generation Noon C&I Peak load reduction C&I customers, for example in California and New York, face high charges for consumption during peak hours; battery storage supplies peak demand and enables customers to optimize use of onsite solar and other energy management programs. Peak load morning and evening Provide peak capacity Utility-scale Dispatchable PV Large-scale PV plants receive lower value for output during sunniest hours; battery storage shifts PV generation into the evening peak. Morning Peak load morning and evening Evening Shifted PV generation Noon Evening Peak
