Did you know?

Using our purpose built limiting system, Scaled Energy have connected over 15 E1320 wind turbines on connections with an export limit of 50kW.

Endurance E4660 - 85kW Wind Turbine

The Endurance E4660 wind turbine is the big brother of the E3120 designed to produce 35% more energy in most windspeeds. The E4660 generates renewable energy efficiently, reliably, safely, and quietly. This turbine is also ideal for larger farms, schools, hospitals and commercial/industrial sites.
