3 ev300 3 kw Remote Category* BLUE MAKES THE GREEN Operation silence Most efficient Attractive size Economical Aesthetic Your Image envergate wind-turbines have been specifically designed for both the distributed generation of power as well as enabling a direct feed into the public electricity grid. Our solution is highly efficient, requires low capital investment and is manufactured to the highest standards. The envergate turbine design is compact in size and extremely quite lending to easy approval of construction permits Its vertically positioned wings allow for an optimized harvesting of the wind even in dynamic conditions between gusts and lulls and do not create noise nor areas of undesired shade. The solution will amortize itself quickly all the while reducing your carbon footprint. * family-houses, cottages, addition to photovoltaics, ridged roofs, radio- and cell towers, heat-, water pumps and -conditioning, mobile deployment, battery charger
