EEA1 500W Wind/Solar Hybrid Controller Off-grid

EEA1 controllers adopt three-phase dump load control, total power of three-phase dump load is 200% larger than the rated power of the wind turbine.

EEA1 500W Wind/Solar Hybrid Controller  Off-grid

Off-grid Connection


     ◆ The product can be manufactured in accordance with either JB/T6939.1-2004 industrial standard, GB/T 19115.1-2003 national standard or users’ technical requirements.

     ◆ EEA1 controllers adopt three-phase dump load control.

     ◆ The total power of three-phase dump load is 200% larger than the rated power of the wind turbine. Ensure safe operation of the overall wind turbine system.

     ◆ When the batteries group damaged or be disjointed, the three-phase dump load will automatically start to avoid the idle run of the wind turbine and the occurrence of runaway accident.

     ◆ It has reverse connection, anti-decoupling and damage-resisting protection of the battery.

     ◆ Over-charging protection of the battery: When the battery is full (the battery pressure reaching 125% of the rated pressure), the controller will automatically carry out three-phase dump load to stop charging the battery.

     ◆ Auto recovery of battery charging: When the battery pressure reduces to 108% of the rated pressure, the dump load will stop three-phase dump load to automatically recover battery charging.

     ◆ For the different wind turbine type, the controller can be equipped with mechanical yawing, furled empennage, mechanical or hydraulic, pneumatic, electric magnetic and other brake functions.

     ◆ The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.
