Product Uses
- The controller will detect the temperature of the environment to adapt to the charging voltage, so the controller should be as close to the battery as possible. (30-100cm is the best distance).
- 18V solar panel is connected with 12V battery, 36V solar panel is connected with 24V battery. The fuse on the battery side is connected to 1.5 times the rated current of the controller.
- In order to make the terminal firm, use colloidal copper wire. Loose power connections and corroded wires can cause resistance connections to melt wire insulation, burn down surrounding materials and even cause fire.
- The controller is only suitable for all kinds of lead-acid batteries. Do not use other batteries, such as lithium battery and nickel hydrogen battery.
| Problem | Possible reason | Solution |
| Connecting the battery,LED not displayed. | Battery low battery Battery is not connected Connected is disconnected | Confirm the battery voltage re-link the controller and battery correctly |
| Solar direct solar panels,no solar symbols and no charge symbols | The solar panel connection circuit is open,shorted or backlinked | Check the operaion of the battery can be connected, if it will be connected together |
| Controller displays LVD | Excessive battery discharge | Check whether the system is reasonable, and whether the power consumption is more than amount of charge |
| Controller displays over current protection | Load short circuit, high power | Check whether the load is short, the power of the load exceeds the designed power, surging power is too high |
