Own power consumption: During charging and discharging: average 15mA Maximum discharge current: 20 A. Working environment temperature: -35-75 °C. Charging mode: MGT mode (tracking the maximum current). Wiring: 1. First connect the positive pole of the load, battery and solar panel to the red line of the controller. 2. Reconnect the negative pole of the load. 3. Then connect the negative pole of the battery to the negative pole of the battery of the controller. At this time, the controller performs a self-test. After the self-test is passed, all indicators light up completely, then the remaining indicators are off and the power indicator lights up. After 6 seconds, the charging indicator light lights up and indicates that the discharge is normal. 4. Connect the negative pole of the solar panel to the negative pole of the solar panel of the controller. The charging indicator light of the controller lights up, the discharge lamp goes out and the charging system is normal. When you wire at night, the control does not switch to the charging state and the discharge state of the third step is maintained until the discharge time of the controller is complete. 5. Connect the three-phase AC input line of the controller to the three-phase voltage output line of the wind turbine. After all the wiring is completed, please wrap the plug with waterproof tape to avoid water ingress. Charging indicator (charging) (green). 1. No light, the battery will not charge. 2. Always on, the battery charges Mct (tracks the maximum current). Discharge indicator (discharge) (red). 1. Does not light up, the load output is off. 2. Is always on and the charging output is on. 3. Slow flashing, low voltage indicator 4. Bl Features Multifunctional with lightning protection. With temperature compensation. Size: approx. 13 x 8.2 x 2 cm / 5.1 x 3.2 x 0.8 inches Strong function: the fully sealed and fully waterproof design significantly improves the stability and reliability of the controller. Safe to use: Power supply devices for reliable performance and long service life. Undervoltage protection, over-voltage protection and over-current protection. Ergonomic design: the full aluminium housing and multi-edge base plate design increase the heat dissipation surface, so that the entire controller is in optimal heat dissipation state for a long time. Save time and effort: battery reverse connection, solar panel reverse connection, battery reverse discharge protection.
