This fits your . Make sure this fits by entering your model number. High Quality: MPPT boost charging, breeze low voltage can start, sufficient energy, can solve the problem of slow fan speed can not be charged. Compared with the traditional PWM charging controller, it greatly improves the charging capacity and the utilization efficiency of the power generation system. Protection Function: With perfect overcharge protection, reverse connection protection, short circuit protection, high temperature protection and other functions, it is more safe and convenient to use. Good Heat Dissipation: Wind controller use Aluminum alloy shell with multi-edge bottom plate design , which increase the heat dissipation area. So the controller keep in an optimal heat dissipation state for a long time. IP67 Waterproof: The fully waterproof protection which grade reach into IP67. Charge controller for wind and solar can work steadily even in very humid environment. Connection: Unique reverse connect protection circuit. For improper operation of positive and negative electrode, user don't need to replace the fuse, only to reset the positive and negative in correct point. Make the whole system will be more reliable.
