Fischer Panda variable-speed Hybrid DC Generators


The Fischer Panda variable-speed Hybrid DC generators have been especially designed for electric propulsion on board. These generators are compact, quiet, powerful and economical. They are characterized by their modern , innovative and electronic regulated hybrid charger which allows a wide RPM range at constant voltage. This technology is a further step into green motion of electric propulsion.


Opposite to the conventional ship’s engine where the propeller is attached mechanically, the independency between RPM and output power of the variable-speed Hybrid DC generator enables the engine to run on the required propeller power. This allows significant fuel savings especially at both low and medium loads. The variable-speed Hybrid DC generator is available in various output voltages up to a current of 300 A and an output power of up to 100 kW

An autostart function prevents the batteries from being drained. A CAN bus connection transfers and receives information from a ship’s control system.


The new Fischer Panda “super silent” variable-speed Hybrid DC generator provides you the comfort for nearly endless electrical cruising (if required).

The multi-usage of your electric propulsion allows:

  • Electric cruising with battery only
  • Hybrid cruising with battery and generator
  • Silent onboard power with battery only for your appliances
  • Hybrid onboard power with battery and generator ( high power demand )
  • Battery charging with generator

Variable-speed Hybrid DC generators feature:

  • Small size and low weight- compact installation
  • Highly efficient – maximum energy
  • Variable speed – load–dependent
  • Easy to install – no forced-air circulation required in machine room
  • Environmentally friendly – low fuel consumption
  • Digital display – up to date all the time


The Fischer Panda generator control system provides generator and electric system information:

  • Temperature data
  • Generator power
  • Power into or from the battery
  • Electric propulsion power
  • “Electric fuel gauge“*
  • Remaining runtime of the batteries*
