e400ⁱ (3 kW)

Available in 48*, 110 200 and 300Vdc

• Charge batteries
• Power water pumps
• Use for resistance heating
• Run high voltage machinery
• Power the national grid
• Boost hybrid systems for increased energy efficiency

The e400ⁱ is the latest development in the Kestrel range. The completely new 120 pole single rotor direct drive alternator incorporates three main shaft bearings to increase stability. The resulting power output is directly proportionate to the rpm’s due to new step generation principles. The e400ⁱ maintains rated output in excess wind speeds, optimising the potential power output and energy yield.
