The new system’s power capacity ranges from 30 to 200 kW power and up to 335 kWh. Occupying up to 4.5 square meters floor space, the QINOUS ESS QCompact includes a complete AC storage system and energy management system. The company claims the system is ideally suited for use in remote regions with no connection to a national grid as well as for grid-connected use in commercial or community applications.
The energy management system manages the flow of energy between various generation units, such as solar plants and diesel generators, and controls frequency and voltage in the grid. There is also a function that makes off-grid operation possible, so area networks can be supplied with a stable source of electricity in the event of a power failure.
QINOUS monitors the state of the components and the system performance is accessible via a secure web-based monitoring system.
The energy storage housing is made of aluminum and high quality insulation material. The interior is divided into two compartments, with the area for the batteries and electronics temperature-regulated and almost airtight to protect against aging which could result from high temperatures, dust, salt mist, insects, and moisture. The other compartment contains the heat exchanger and transformer.
A QINOUS ESS QcompactM with 90 kW and 165 kWh will soon be put into operation in a village in Tanzania. Together with an existing solar facility, the company hopes it will ensure a clean energy supply for the village. “The solar facility in combination with our storage unit offers the ideal solution for the village to gain more independence from expensive, environmentally harmful diesel fuel,” says Busso von Bismarck, Head of Business Development at QINOUS.
