1. Automatically charge the battery. 2. The rectifier and brake circuit of this controller adopts an integrated module, which is more advanced than the traditional terms of heat dissipation and reliability. 3. Adopts a fully sealed and waterproof design, and its protection grade reaches above IP67. It can be used normally for a long time even in water. Notes: Confirm that the output voltage of the wind turbine generator is consistent with the rating voltage of the battery. Connect the wires in the following order, first connect the positive and negative poles of the battery, and then connect the three-phase voltage output of the fan. Please connect the battery and wind turbine to the controller in accordance with the instructions. Reverse polarity or wrong position will lead to abnormal operation of the system or even complete damage to the controller. Wiring mode: 1. Connect the positive and negative poles of the battery to the positive (red) and negative (black) terminals of the battery of the controller. 2. Respectively connect the three-phase output voltage of the wind turbine to the three-phase input (green line) terminal of the controller fan. Parameters: 1. Maximum input AC voltage: AC35V 2. Output voltage: 12V / 24V 3. Battery charging cut-off voltage: 14.5V 0.3V / 29V 0.3V 4. Maximum charging current: 15A (12V) maximum charging current: 10A (24V) 5.
