The Britwind H1 delivers 1,000W at 12 m/s wind speed, with a BWEA reference power of 768W at 11 m/s. Annual energy yield varies by location: at an average wind speed of 5 m/s, you can expect approximately 898 kWh per year, while at 6 m/s you'll generate around 1,473 kWh annually.
No, the Britwind H1 doesn't require concrete foundations. It uses an 8-metre gin pole tower system with galvanised guy ropes and ground anchors, making installation quicker and more cost-effective than traditional wind turbines.
The H1 is exceptionally quiet, producing only 35 dB LAeq at 5 m/s wind speed when measured downwind. This is roughly equivalent to a whisper or a quiet library, making it suitable for residential installations.
Yes, the H1 is specifically designed for wind/solar hybrid systems and works brilliantly alongside solar PV installations. It's particularly effective at generating power at night and during winter months when solar output is lower, providing year-round renewable energy.
Three packages are available: 1) Turbine and controller only (£4,018), 2) Turbine, controller, and tower mounting kit with clamps, couplings, ground anchors, guy ropes, and assembly instructions (scaffold tubes sourced locally), 3) Complete system including turbine, controller, tower kit, Duracell Purestorage II 5kWh battery, and Solis S5 3.6kW hybrid inverter. Budget around £7,000 + VAT for full installation (currently 0% VAT on new domestic installations).
Yes, the H1 features the AirforceControl charge controller with Bluetooth connectivity and web app access, allowing you to monitor performance and remotely start or stop the turbine from your smartphone.
The H1 starts generating power at a cut-in wind speed of 3.5 m/s and automatically cuts out at 12.5 m/s for safety. The turbine is built to survive extreme winds up to 52 m/s and operates in temperatures from -20°C to +50°C.
The H1 offers flexible battery charging with both 24V and 48V options, making it compatible with most off-grid and hybrid energy storage systems. The complete package includes a 51.2V 5kWh LiFePO₄ battery for reliable energy storage.
