SMA Wind Energy Inverters WINDY BOY 3800

With a maximum efficiency of 95.6 percent, the Windy Boy 3300 and 3800 inverters are among the most cost-effective for small wind turbine systems. The weatherproof enclosure and broad temperature range permit installation at nearly any location, and thanks to the OptiCool cooling system, the inverters operate at outside temperatures of up to 45 °C at maximum output. The programmable polynomial curve enables optimal adaptation to the turbine characteristic curve, thus increasing yield. The inverter can supply reactive power, contributing significantly to grid stability.
