It starts generating in light winds, delivers around 60W at 5m\/s and up to approximately 840W peak at about 15m\/s, making it suitable for continuous trickle charging and higher output during strong winds.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAvailable in 48V version with dedicated MPC-2 controller to rectify and regulate turbine output for battery charging.\u003c\/li\u003e\n\u003cli\u003eLow-friction, brushless three‑phase alternator with rare-earth magnets and slipring for 360° rotation, reducing cable twisting and maintenance.\u003c\/li\u003e\n\u003cli\u003eAutomatic mechanical furling tail that activates around 15m\/s to reduce rotor speed, protect the tower and moderate output in gale‑force winds.\u003c\/li\u003e\n\u003cli\u003eStarts running from about 2m\/s and cut‑in charging from around 3m\/s, extending generation hours in light and moderate winds.\u003c\/li\u003e\n\u003cli\u003eMPC‑2 controller includes LCD display, Run\/Stall\/Reset control, temperature‑compensated charging and options for remote sensing and shutdown.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhere to use\u003c\/h2\u003e\n\u003cp\u003eThis Rutland FM1803-2 48V wind turbine is designed for land-based off-grid systems where a reliable DC power source is needed and grid connection is impractical. Typical applications include telecom masts, CCTV and security, instrumentation and environmental monitoring, rural homes and cabins, farm buildings and remote safety or signage systems.\u003c\/p\u003e\n\u003cp\u003eThe turbine can be used stand‑alone to charge a 48V deep‑cycle battery bank, or as part of a hybrid wind‑solar system alongside PV modules and a solar charge controller. For UK projects, Energian can arrange design and installation via trusted partners to ensure the tower, foundations, cabling, protection and battery system meet local standards and site conditions.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eModels available\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNominal system voltages: 12V, 24V and 48V versions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePower and current ratings (FM1803-2 performance curve)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e5m\/s (approx. 11mph) wind speed: 60W (4A at 12V) \/ 60W (2A at 24V) \/ 60W (1A at 48V)\u003c\/li\u003e\n\u003cli\u003e11m\/s (approx. 25mph) wind speed: 460W (32A at 12V) \/ 460W (16A at 24V) \/ 460W (8A at 48V)\u003c\/li\u003e\n\u003cli\u003e15m\/s (approx. 33mph) wind speed: 404W at 11m\/s (12V\/24V), 840W peak at 15m\/s.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGenerator and rotor\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenerator type: low-friction, brushless three‑phase alternator with high‑specification rare‑earth magnets\u003c\/li\u003e\n\u003cli\u003eOutput: variable frequency AC, approximately 120V line‑to‑line under normal conditions\u003c\/li\u003e\n\u003cli\u003eYaw rotation: sliprings and brushgear for 360° free rotation on tower\u003c\/li\u003e\n\u003cli\u003eAerofoil blades: three injection‑moulded glass‑filled blades at fixed pitch\u003c\/li\u003e\n\u003cli\u003eRotor: 3‑blade aerodynamic rotor runs in around 2m\/s wind, generation starts at about 3m\/s\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFurling and protection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFurling tail system: automatic mechanical furling at wind speeds over 15m\/s (approx. 35mph \/ 56kph)\u003c\/li\u003e\n\u003cli\u003eGoverning devices: electronic stalling via MPC‑2 controller to prevent battery overcharge;
