Wind turbine FT-2000L2 | 2 kW | 48 V | off-grid / hybrid

FT-2000L2 2 kW is a wind turbine for off-grid systems with an output of 48 V AC.

Key specifications

• Rated power: 2.0 kW
• Maximum power: 2300 W
• Output voltage: 48 V AC
• Output: three-phase AC
• Start-up wind speed: 2.5 m/s
• Practical generation from: 4.5 m/s (indicative)
• Rotor diameter: 3.2 m
• Weight: 60 kg

Key features

• 48 V system voltage: designed for use with battery banks through an appropriate controller, prioritising energy storage and increased self-consumption.
• 2 kW output for battery systems: a power class suited to typical 48 V storage systems, supporting stable charging without excessive installation loads when correctly designed.
• Gearless permanent-magnet generator (PMG): efficient operation at practical wind speeds and low resistance torque support off-grid and semi-off-grid use.
• An energy source for storage: the turbine is intended to charge batteries and supply loads through a battery inverter, rather than feed electricity directly into the grid.
• Low-vibration construction supports long-term operation and the mechanical stability of the installation, particularly in autonomous systems.
• NSK bearings support durability during continuous operation.

Who it is for

• Individuals and households prioritising battery charging and self-consumption rather than direct grid connection.
• Owners of off-grid or semi-off-grid installations using a wind turbine as a supplementary source for 48 V batteries.
• Farms and technical facilities using battery storage to supply loads autonomously.
• Installers and integrators of 48 V battery systems implementing hybrid wind, solar PV and storage projects.

Applications

• Charging 48 V battery banks as part of a hybrid wind and solar PV system, improving energy availability during periods of low sunlight.
• Off-grid and backup systems where continuity of supply to essential loads is important.
• Supplying remote facilities or sites where a grid connection is limited or uneconomic.
• Engineered installations where the turbine supplies energy to storage rather than feeding the grid directly.

System integration

Important: The turbine produces three-phase AC. Correct operation with battery storage requires a charge controller matched to the system voltage.

Installation guidance

• Controller/rectifier and protection selection should follow the 48 V installation design.

Real-world operating conditions

Energy production depends directly on local wind conditions. In practice, horizontal-axis wind turbines (HAWT) usually produce more consistently above approximately 4-5 m/s and perform best with smooth, minimally turbulent airflow. Sites with frequent turbulence caused by buildings, trees or terrain obstacles may produce less energy, reflecting the operating characteristics of HAWT turbines.

When this model is not recommended

• Applications requiring direct connection to a 230/400 V electricity grid without battery storage.
• Operation without a dedicated charge controller, protection and a correctly selected 48 V battery bank.
• Installation in highly turbulent locations, such as low masts or sites with terrain obstacles, where energy production will be inefficient.

FAQ

Can the turbine charge 48 V batteries directly?
No. The turbine produces three-phase AC. A controller/rectifier matched to the 48 V system is required for battery storage.

At what wind speed does practical generation begin?
Usually from approximately 4-5 m/s with good airflow; turbulence may reduce output.
