The latest achievements and advance in fuel cells and flow batteries is revolutionizing greatly the transportation and energy storage sectors.

Zekalabs AC-DC and DC-DC bidirectional converters and inverters can be the core components of a fully reliable and robust electrical power conversion system utilizing these technologies. We know how demanding these technologies are and we work effortlessly to provide the most efficient power converters for coupling with it.


Key features include: 

  • High-power input/output from 5kW or 15kW
  • High voltage input/output up to 450Vdc
  • Bi-directional units that can transfer power in either direction
  • Can be used either in buck or boost mode
  • Can work in parallel for increasing the output power
  • Very high efficiency - greater than 95% for isolated units
  • Using SiC technology where appropriate
  • Galvanic isolation
  • Air/water(liquid) cooled units
  • IP67 protection versions
  • Modbus RTU and CAN communication and control lines

Moreover, unique monitoring features and control functions give the whole system advantages for both during commissioning and normal operation.
