The QINOUS ESS QMedium is ideal for self-consumption increase and back-up power for commercial and industrial application, as well as for island operations.

The QINOUS ESS QMedium provides power of up to 500 kVA and a capacity of up to 828 kWh. It is based on a standard ISO 20ft shipping container. The interior is separated into two sections. One section is completely airtight, preventing deterioration effects from dust, salt mist, insects or humidity. The other compartment houses the heat exchanger, the AC system and the transformer.

The outdoor cabinet is made of a vandalism proof double wall aluminium structure and state-of-the-art thermal insulation material to withstand even harsh climate conditions.
