300W Wind Generator
12Vdc, 24Vdc, 48Vdc
Land/Marine Version
Ampair (Pacific) 300 wind turbine system
The Ampair (Pacific) 300 wind turbine system is suitable for larger yachts, small industrial locations, or remote holiday cabins. This microwind turbine has evolved from the outstandingly rugged Ampair 100 unit with the addition of the revolutionary PowerFurlTM blade pitch control system, advanced aerodynamic blade design and a more powerful generator.
Ampair 300 Features:
* combines non-intrusive operation with elegant modern styling,
* accurate aerofoil construction of each turbine blade optimizes performance, minimizes noise and vibration,
and improves power-to-weight ratio,
* rigid blade design avoids "whooping", "motor boating", or "screaming", (vibration, resonance, and flutter),
* integral marine-grade sealing system protects internal components from condensation and corrosion,
* simple pole mounting allows installation in many locations,
* operates with no thermal cut-outs, commutator brushes, or complex electronics,
* revolutionary simultaneous PowerFurl™ blade pitch control system reduces turbine speed in high winds
while maintaining power output,
* three phase AC output from turbine minimizes voltage drop and permits use of smaller cables;
external DC rectifier included in system,
* wide range of accessories available including various mounting options

Power output
Click the chart below for output curve.
* Halve amp values for 24V generator.
* Charging values decrease only slightly with rising battery voltage.
* For Amp Hours per day, multiply charging current at average location wind speed by 24.
* For Amp Hours per week multiply by 168.
* For Watt Hours multiply Amps by 12.5V by hours.
* Wind speed: 1 Knot = 0.5m/sec, 1 Knot = 1.152 mph
* This generator can charge a battery simultaneously with other sources such as solar panels and
an engine driven alternator.DC cable length and voltage drop must be evaluated carefully when laying out system. Click here for our simple voltage drop calculator.

Maintenance and Recommended Spare Parts
The Ampair 300 is designed so that users can strip it down in the field and replace those components that wear out over time or that become damaged in accidents. In remote locations or on long sailing voyages accidental damage is always a possibility. We suggest that spare wind turbine blades be carried. Recommended short-term and long-term spare parts are listed below.
| Short-Term Spares | Long-Term Spares | ||
| A00-SP-30 | Pivot Seal | A00-SP-31 | Pivot Bearing Set (upper & lower, O-ring, spiral lock ring) |
| A03-SP-11 | Brush Set | A36-SP-21 | Hub Cap Screw |
| A03-SP-12 | Blade Set | A03-SP-22 | Rectifier Assy & Heatsink (suitable as emergency spare in case of regulator failure |
Mounting options
Ampair manufactures a range of mountings for the Ampair 300. Some are only intended for use on boats, some are only intended for use on land, and some can be employed in both situations. The unit with adaptor mounts on 48mm (1.89") O.D. pipe.
