About this item

• Reliable Power in Gentle Breezes Compatible with 12V battery systems, this wind turbine seamlessly integrates into off-grid setups, ranging from compact residential storage banks to small farm or remote applications. With a cut-in wind speed of 6.7 mph, it begins charging in lighter breezes, helping maintain steadier day-to-day energy production in coastal, inland, and variable-weather regions. The straightforward 12 V architecture also supports future upgrades—users can expand their storage capacity without needing to replace the turbine or controller.
• Up to 400W for Reliable Energy Supply Delivers up to 400 watts of clean DC power at a rated wind speed of 28 mph, providing dependable capacity for everyday off-grid loads. In cabins, boats, and farm sites, the output readily supports LED lighting, communications/network gear, sensors, security cameras, small DC pumps, and routine battery charging for tools and devices. As conditions change, it functions as a steady charging source on windy nights and during shoulder seasons, or pairs with solar to cover cloudy days and evening hours, creating a more balanced and dependable hybrid energy mix for long-term use.
• Digital MPPT Safety & Manual Stop Switch A digital-controlled MPPT manages charging and adds layered protection, including over-speed, over-voltage, over-current, and thermal safeguards. For storms and maintenance, an on-site manual stop switch lets users halt the turbine quickly and safely.
• Durable Design with Long Lifespan Built for long-term use, the turbine features plastic steel blades and a protected drivetrain for minimal maintenance. It is designed to survive winds up to 112 mph when the manual brake is engaged, providing a safety margin during storms. Bearings are estimated to last 10 years at sites with an average wind speed of 12 mph. Routine upkeep is simple: every six months, inspect blade condition and fasteners, clean the blades, and verify that electrical connections and battery terminals are tight and corrosion-free.
• Easy to Install, Monitor, and Maintain Designed for straightforward DIY setup with a standard round-pole mount and clearly labelled, pre-wired connections. The integrated MPPT controller and manual stop switch are positioned for easy access, allowing you to secure the turbine during storms and perform service safely from the ground. Day-to-day care is minimal: inspect the blade condition and hardware periodically, keep electrical connections clean and dry, and engage the manual brake before maintenance or severe weather conditions.
