Blower diameter: SRVF-320: about 320mm; SRVF-350: about 350mm7. 35W/40W solar panel size: about 46 x 50cm8. Product size: about 56.5 x 56.5 x 26cm9. Weight: SRVF-320: approx. 7.8kg; SRVF-350: approx. 8.4kgFeatures:1. Lightning strike protection, rain and cloudy weather and night can use the power adapter to make up for the power, you can also use the remote control (not included) for remote control2. Aluminum alloy base, corrosion-resistant body light, can be shaped arbitrarily according to the roofing conditions3. Fluid structure deflector, reduce airflow transformation resistance, improve the export flow structure4. Automatic temperature control, higher than 25 degrees Celsius to start, lower than 25 degrees Celsius to stop5. Snap design, stainless steel reinforced screws, welding treatment, strong and safe6. DC brushless frequency conversion motor, adaptive to changes in light intensity, tracking solar output power point, 5 times higher efficiency, efficient and quiet operation7. 35/40W solar panel, 3mm high-efficiency monocrystalline silicon, light conversion rate of 25% or more, comes with a high-strength aluminum alloy frame8. Aluminum alloy heat sink cover, strong heat dissipation, integrated design, waterproof, cold-proof and high temperature resistant9. Aluminum alloy 5-blade fan, low vibration, low noise, durable, not easy to deformationInstallation steps:1. Cutting: position and cut a circle on the roof2. Fixing: fix the aluminum base plate with the roof and make it fit3. Installation: install the wind turbine body and windproof support bar to fix with the base plate4. Tighten: adjust the angle of the solar panel, then tighten the screws
