QINOUS, a German manufacturer of smart energy storage systems, developed an extremely compact system in the power range from 30 to 200 kW power and up to 335 kWh capacity. Occupying only up to 4.5 square meters floor space, the QINOUS ESS QCompact includes a complete AC storage system and energy management system. 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.
“Like all our storage solutions, the QINOUS ESS QCompact is easy to install and operate,” says Steffen Heinrich, Managing Director of QINOUS. “What makes the system special is its compactness and performance range. It contains the most storage capacity in the least space, including the power electronics, the lithium-ion batteries, and a specially developed energy management system. All this makes the ESS QCompact unique in the market.”
The compact storage system provides up to 200 kVA of power and has a capacity of up to 335 kWh, while taking up just 3.0 to 4.5 square meters of floor space and can be shipped in a high-cube container. The integrated, comprehensive energy management system ensures a secure and efficient power supply. It manages the flow of energy between various generation units (e.g. solar plants, diesel generators, energy storage system) and controls frequency and voltage in the grid. The integrated black start function makes off-grid operation possible. Thus, area networks can be stably supplied in the event of a power failure.
QINOUS monitors the state of the components along with a variety of system parameters. The system performance is accessable via secure access at a user-friendly web-based monitoring system. The energy storage housing is made of aluminum and high quality insulation material. The interior is divided into two compartments. The area for the batteries and electronics is temperature-regulated and almost airtight to protect the components against aging resulting 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, it will ensure a clean energy supply. “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. Another QINOUS ESS Qcompact L with 120kVA/125kWh is already in operation in Bavaria performing peak-shaving at a manufacturing facility.
