How to Use a Solar Charge Controller?

The most basic function of the solar charge controller is to control the battery voltage and open the circuit, i.e. if the battery voltage rises to a certain level, it stops charging the battery. The old version of the controller closes the opening or closing of the control circuit mechanically and stops or starts the energy supplied from the power supply to the battery.

What are the options for errors and solutions when using the solar charge controller?

1. The load of the solar charge controller does not work

(1) During the day the controller has a light control.

(2) Battery power is not sufficient.

(3) Whether the wiring is correct.

(4) Remove all cables, repeat the above installation process and have the controller re-identified.

2. The solar charge controller can be used for a few days, but it no longer works after a few days

(1) Solar cell wiring is wrong.

(2) The solar cell is not properly connected.

3. The solar charge controller cannot be controlled by light

(1) Solar cell wiring is wrong.

(2) This function is not set, please reset.

4. The solar charge controller works immediately after switching on and cannot be controlled by light or time

(1) This function is not set, please reset.

(2) The ambient light of the solar panel is strong enough.

5. The working display of the solar charge controller flashes continuously

The load is short or the load is too great.

What is the working mode of the solar charge controller?

1. Pure light control mode: If there is no sunlight, the intensity decreases to the starting point. After the solar charge controller has confirmed the start signal with a 10-minute delay, the load is switched on according to the set parameters and the load starts to work; If sunlight is present, the intensity of light When the starting point is reached, the solar charge controller delays the output by ten minutes after the kill signal has been confirmed and the load stops working.

2. Mode of light control plus time control: The start process is the same as for pure light control. When the load reaches the set time, the solar charge controller switches off automatically and the set time is one to 14 hours.

3. Manual mode: In this mode the user can control the opening and closing of the solar charge controller using the keys, whether during the day or at night. This mode is used for some special loading situations or during debugging.

4. Debugging mode: Used for system debugging. If a light signal is present, the load is switched off and the load is switched on without a light signal, which is convenient to check the correctness of the system installation during installation and debugging.

5. Normally open mode: When the load is switched on, the solar charge controller always maintains the output state. This mode is suitable for loads that require 24-hour power supply.

What precautions should be taken when using solar charge controllers?

Wiring sequence: The user must make sure to connect the solar charge controller first to the battery, then to the solar panel and finally to the load. Note: The required wiring sequence must be adhered to. Since the order is disordered, some solar charge controllers may not automatically detect the 12V/24V/48V system, leading to the regulator not functioning normally.

Users must be careful to ensure that the battery is not switched off, otherwise this can have serious consequences. The size of the fuse shall be two to three times the rated current.
