ista-energy WindSter Wind Turbine Controller (4 kW, 380 V)

The WindSter is a controller designed for energy management of wind turbines with a maximum power of 4 kW. The device monitors system performance and works with wind turbines operating at voltages up to 410 V AC.

The ista-energy WindSter controller is designed for advanced control and monitoring of wind turbines. The system supports turbines with a nominal power of 3500 W and offers comprehensive measurement functions, including recording of voltage, current, and generated power. The device allows logging historical data on wind speed and duration, making it easier to evaluate operational efficiency. Additionally, the equipment features protection functions, such as braking the turbine when pre-programmed maximum parameters are exceeded.

Key features

• Monitoring of AC/DC voltage, current, turbine power, and component temperature
• Automatic turbine braking when set values for voltage, RPM, and power are exceeded
• Ability to stop operation during high winds or low efficiency using an anemometer
• Passive cooling and silent operation at 0 dB
• RS485 communication dedicated to connecting an external anemometer
