Bidirectional converter Airdra25

poweruniversalModbus

Universal 25kW fuel-cell to grid converter. The Airdra25 offers bi-directional power conversion from any type of fuel-cell to the AC power grid. It can operate grid connected as well as stand-alone, creating a local micro-grid. With its 19” form factor and galvanic isolation, multiple Airdra25s can be easily paralleled, interfacing fuel-cells up to 500kW. The module offers high efficiency (up to 98%) and is air cooled with a low noise speed-controlled fan tray. The module complies with the latest international Grid codes (E.g. RfG, IEEE1547) and can be accessed via a standardized Sunspec Modbus Ethernet interface.​ The Airdra25 is a universal power converter which can be used to interface with different type of fuel cells including regenerative ones. Due to its bi-directional capabilities it can also be used to connect batteries or electrolysis stacks to the grid. The Airdra25 can operate grid connected as well as in stand-alone configuration. As it complies with the latest grid code standards, it is fully prepared for the future grid with a high penetration of renewable energy sources. Its galvanic isolation offers the possibility of flexible grounding and easy paralleling, up to 500kW. The SunSpec Modubus ethernet interface, facilitates control and monitoring of the Airdra25. A separated Master/Slave interface is available to guarantee even power distribution and stable operation for almost unlimited paralleling of modules.
