Feature: 1. When the battery is fully charged, the wentylator will be automatically braked by the internal control circuit. When the battery voltage drops to the restore voltage, the wentylator will resume charging the battery, thereby protecting the wentylator and the battery. 2. Modular design: the performance of the entire system is guaranteed. Part of the rectifier and brake circuit of the controller adopts integrated module, which is better pod in terms of heat dissipation and reliability. 3. Reliable performance: This ma fully sealed and completely waterproof design, and the protection level is IP67 and above. Even if it is placed in water, it can be used normally for a long time, and stability and reliability are greatly improved. 4. Premium: aluminum alloy housing and multi-edge bottom plate design will increase the heat dissipation area. It can keep the controller in the best cooling condition for a long time. 5. Easy to install: designed to be lightweight and compact, the wind turbine controller is very convenient to install.
