Frequently-Asked Questions

Q: What can a 400 watt wind turbine power?

A: With the Automaxx 400W wind turbine, you can power a range of everyday electrical devices and appliances. It’s perfect for lighting up your outdoor spaces with energy efficient LED lights, charging your electronic devices like smartphones, tablets and laptops. However the power output from a wind turbine depends on the wind speed, battery bank system and inverter. With a larger capacity battery bank and inverter you would be able to power more electric appliances.

Q: Do 400 watt wind turbines put out AC or DC?

A: The AC power generated by Automaxx’s 400W wind turbine undergoes conversions to DC power using the integrated charge controller. This DC power is subsequently stored in a battery bank for future utilization.

Q: How many amps does a 400W wind turbine produce?

A: The maximum output of Automaxx 400W wind turbines is 33 amps. The amplitude of amperage generated is contingent upon several variables, including wind velocity, wire gauge, wire length and battery capacity.

Q: How does a 400W wind turbine compare to other sizes in terms of efficiency and performance?

A: Our 400W wind turbines stand out for their impressive efficiency and performance. While larger turbines may offer higher power output, our compact 400W turbines are specifically engineered to excel in moderate wind conditions. They strike the perfect balance, providing optimal energy production in areas with consistent and moderate wind speeds.

Q: What is the expected lifespan of a 400W wind turbine?

A: When it comes to longevity, our 400W wind turbines are built to last. With rigorous quality control measures and durable materials, our turbines boast an average lifespan of 20 years or more. This extended lifespan ensures you enjoy years of reliable and cost-effective renewable energy generation.

Q: What are the maintenance requirements for a 400W wind turbine?

A: We understand the importance of hassle-free ownership, which is why our 400W wind turbines require minimal maintenance. Our turbines feature robust components and innovative design elements that reduce the need for frequent servicing. Routine inspections and occasional lubrication are all that’s needed to keep your turbine operating at peak efficiency.

Q: How much space is needed to install a 400W wind turbine?

A: Our 400W wind turbines are designed with compactness in mind, making them ideal for installations where space is a consideration. With their small footprint and efficient design, our turbines can be easily integrated into various settings, including residential properties, farms, and off-grid applications.
