1 CONTAINER MWh Electrocell presents the INNOVA MWh on/off-grid energy storage system. Installed inside a 40 ft container includes 4 units of 540V@40Ah battery packs, system control cabinet, 250kW PCS and air conditioning system. Grid Power Distribution Cabinet 400Vac Industrial Area Power Supply 400Vac 400Vac 400Vac Air Conditioner PCS (250kW) Battery Energy 34.4V*4pcs = 537.6V 537.6V@40Ah*4pcs = kWh VDC VDC Battery Pack Control Cabinet VDC Battery Pack Picture - Schematic diagram / system power circuit

2 WORKING MODES When the AC grid is normal, the battery packs is loaded over the converter through the control cabinet. The system works on grid. When the AC grid is unstable, the system works off-grid with the battery pack. During off-peak period the battery system is recharged through the PCS. SYSTEM COMPONENTS Name Quantity Specs Container 40 ft LiFePO4 56 MWh INNOVA Energy Storage System Busbar Control Cabinet PCS 2 for each 28 batteries pack 4 units 250kW Distribution Cabinet AC380V 800A Air Conditioner 2.4KW POWER CIRCUIT DESIGN The battery pack can be charged by the two-way inverter during off-peak time, battery pack supplies electricity to the factory through the two-way inverter during peak time, the two-way inverter can work collaborating with grid during peak time. EMERGENCY POWER SUPPLY MODE The power grid is cut off, and the two- way inverter operates in the off grid mode and the battery pack is discharged to supply the plant.
