EFD series (EFD10KW, EFD20KW, EFD30KW AND EFD50KW) still can be used as grid tied system. However, a grid tied inverter to be needed for wind turbine system to be connected to state grid.

Small wind energy systems that are connected to the electricity distribution system are called grid-connected systems (on grid). A grid-connected wind turbine reduces the power consumption from the utility company and can be used for lighting, appliances, electric heat etc. When the wind system produces more electricity than required, the excess is sold to the utility company. Whenever wind powering is insufficient, the grid system fills the gap.
The grid connected applications are implemented successfully in countries that have introduced an incentive plan for renewable energy. The incentive plan may include subsidies on installation, net metering option, and subsidized feed-in tariffs (fit) otherwise known as renewable energy payments.
Calla glory grid tied wind turbines including eg30kw, eg50kw which can work under on-grid circumstance without an extra inverter which is different from regular wind turbine generator system.

Products of efd series are equipped with aluminum cover, got advantages on both performance and appearance. The key parts of controller are integrated with international top brand, like plc from mitsubish, contactor from schneider, etc. Convenient can be brought to the end users for testing and using the generator system by applying touch screen on interface controller and remote control by gprs.

Nacelle adopt aluminum alloy compression molding, light in weight;
Silicon steel sheet: using model 600 cold rolling silicon steel sheet, difficult to be heated;
Rotor: material of the magnet is ndfeb( h grade), high efficiency and thermostability;
Tail: molding by fiber glass mat, good suppleness and high intensity.

Blades made from carbon fiber, molding, and the weight less than 500g.
The whole structure made of aluminum alloy except stator and rotor of motor.
Anti-vibration measures applied to the rear of windmill, runs smoothly.
Connected to the pole with clamp, simple and reliable, do not need to match the flange.
Easy installation, only one screw be used for 3 blades installation.
