E400i Kestrel

Kestrel e400i

Product Description:

Wind‑powered generators that produce electricity, often used in hybrid solar‑wind systems. Kestrel wind turbines are among the best performing and most efficient wind power systems. Kestrel’s strict adherence to quality standards and continuous development of Kestrel technology has resulted in a line of high quality, quiet, powerful, and robust machines in 600, 800, 1000 and 3000 Watts rated power that are both reliable and cost effective.

All Kestrel turbines feature Full Axial Flux Discoid Technology, for high efficiency and increased energy production in lower wind areas. All models use patented pitch control, allowing blades to maintain rated output in excess wind speeds and optimizing overall power production.

Energy may be harvested at any different wind speed exceeding cut-in speed and rated output is maintained through rotor turbulence and pitch control in high winds. Energy output is intrinsically linked to your site’s wind distribution, topology and altitude as well as tower height and the height of trees or structures in the area.

Product highlights:

  • 6.3 mph cut in wind speed, 24.6 mph rated wind speed 3300W, max power rating at 12ms ̄ˡ
  • The e400i is our largest in-stock turbine and optimizes your renewable energy output and performance through efficiency and size
  • The e400i uses 3 aerofoil blades with a 13.12-foot rotor diameter
  • The e400i moderates noise emissions effectively, making it unobtrusive for its size and a reliable method of substantial renewable energy production
  • The e400i advanced direct drive alternator incorporates three main shaft bearings for longevity and increased reliability
  • Appropriate for water pumping, repeater stations, heat production, small wind farm installations, battery charging, grid tie or hybrid systems, the output voltage can range from 48, 200 and 300 Vdc
  • Used around the world to generate dedicated power for housing, community and health centers not connected to the national grid
  • Tower top mass is 331 lbs
  • Used with a tripod tower and a charge-only controller

    • RES works with residential, commercial, and remote applications and can evaluate storage, generator integration, electrical infrastructure, controls, and ongoing support as one system.

    • Alaska temperatures affect battery performance and charging, so siting, enclosures, and heating are part of the design.

    • Batteries carry loads instantly and silently, while a generator extends runtime when the outage outlasts stored energy.

    • Runtime depends on the critical-load profile, battery capacity, and whether a generator or solar recharges the system. RES designs to a runtime target agreed with the facility.

    • RES starts with an energy audit and load calculations to separate critical loads (refrigeration, servers, medical or process equipment, life-safety lighting) from loads that can wait. The critical-load list drives battery capacity, generator size, and the electrical integration design.

    • Contact RES with your project location, facility type, current energy sources, approximate energy requirements, and operational goals.

    • Yes. RES provides operations and maintenance services, including monitoring, preventative maintenance, battery testing, troubleshooting, repairs, and system upgrades.

    • Renewable energy may help reduce electricity purchases, fuel consumption, or exposure to changing energy costs. Actual financial benefits depend on system design, energy demand, utility rates, fuel costs, project location, and installation expenses.

    • Yes. RES serves customers across Alaska, including rural and remote locations.

    • Yes. RES designs hybrid power systems that can combine renewable generation, battery storage, generators, and existing electrical infrastructure.
