Product Details

Product features:
1. Use high-quality materials with guaranteed quality
2. High conversion intelligent charging, using multiple power tracking algorithms, greatly improves charging efficiency, with a conversion rate of up to 98%
3. Using high-frequency switching MOSFETs with extremely low conduction resistance instead of traditional rectifier diodes greatly improves conversion efficiency, reduces the temperature of the entire machine casing, and achieves the smallest casing to achieve greater power output
4. Equipped with lithium battery activation function, when the lithium battery is discharged to the over discharge protection value, the lithium battery will lock itself and the outside world cannot charge and discharge it
5. Multiple display effects, including four digit digital tube scrolling display, battery voltage, photovoltaic current, photovoltaic power, etc

matters needing attention:
1. It is strictly prohibited to use the controller under excessive pressure or power. Only connect the battery and not the solar panel. The controller does not work
2. Before installing the controller, please determine the voltage range, which must be consistent with the battery voltage. It is strictly prohibited to charge a low range battery with a high range voltage
3. Installation steps: First connect the solar panel to the controller, and then connect the battery. The input and output of the controller are both positive with a red line and negative with a black line
4. The length of the wires connecting the controller should be as short as possible to reduce electrical losses
5. Solar panels should be placed in a place without any obstruction of sunlight for use
6. The controller may generate heat during operation, and it is recommended to install it in a ventilated and heat dissipating environment
7. The blue (black) line in the charging line of the original electric vehicle charger is the positive pole, and should be connected to the red line of the controller output line. Remember to
8. It is strictly prohibited to replace fuses with larger ones or copper wires. The controller fuse is 25A
