UK manufacture Marlec Engineering.

Their wind chargers are ideal for maintaining the charge in 12 or 24V batteries to provide remote power. Uses include: on boats or caravans to run onboard electrics; powering lighting in remote buildings and stables; powering area lighting and providing remote power supplies for telecommunications or roadside signs.

They start in low windspeeds yet are protected in strong winds to give maximum possible energy production and high reliability for many years of service and can be combined with photovoltaic (PV) modules to give a balanced supply throughout the year.
