The Medium Capacity ESS is designed for industrial and commercial building applications. With the expiry of grid feed-in solar PV policy, corporate buildings can switch to storing their energy into ESS during high sun irradiation period and discharge it as base load supply during periods of higher grid tariff. Zero-Export power function is part of a standard feature in the ESS to prevent feeding to grid during low load period.

For the industrial plant and factory owners, their strategy is to maximize their plant machinery production capacity by drawing on buffer energy for peak demand management. The ESS will store power from the grid supply during lower operation period and release this stored energy as when the machinery loads exceed a set point, providing the high current peak loads from machinery operation.

The Medium Capacity ESS is also designed as a standardized module with self-contained LFP battery, PCS power electronics, BMS & EMS controller logic system and realtime CAN-bus communication for parallel synchronized operation. Each Medium Capacity ESS module comprises of a 50kW PCS with standard 100kWh or extended 200kWh LFP battery system. The ESS node is ready to be installed as a ready-to-use energy plugin to the building’s main electrical distribution system. To achieve a higher capacity, multiple nodes can be expanded in parallel up to a 20x module connected system. The feeder point can be distributed across the building premises and synchronized via the realtime CAN-bus communication link. The maximum capacity from a parallel Medium Capacity ESS is a 1,000kW ESS system.

The key features of Medium Capacity ESS are 15years designed battery lifespan, refrigerant air-cooling, integrated dual fire suppression, and IP54 rated outdoor cabinet for direct outdoor installation.
Engineering design and software tuning will be provided for a parallel connected system. Tuning of the EMS software to optimize for the customer specific loads and tariff conditions can be offered with maintenance services contracts.
