The solar charge controller is an electronic device for controlling loading and unloading and has functions such as pollution protection, flood protection, overload protection, short circuit protection and digital parameter displays. If you want to choose a solar regulator, it is recommended to choose according to your own needs. In general, solar charging regulators have watertight protection measures. Choose according to different needs.
What is the solar charge controller?
How do I set the solar charge controller?
How does the solar charge controller protect the battery?
The solar charge controller uses a high-speed CPU microprocessor and a high-precision A/D analogue digital converter. It is a microcomputer data acquisition and monitoring control system. At present, solar charge controller can not only quickly capture the current operating status of the photovoltaic system in real time, retrieve the operating information of the photovoltaic power plant, but also provide detailed historical data of the photovoltaic power plant to provide users with accurate and accurate results. The solar charge controller provides data on the rationality of photovoltaic system design, and provides verification for evaluation and system component quality reliability. In addition, the solar charge controller also has a serial communication data transmission function that allows several photovoltaic substations to be centrally managed and remotely controlled
Setting Method: Press the switch switch switch for five seconds, the LED flashes the MODE ad number, release the key each time you convert a number until the number shown on the LED matches the number corresponding to the mode selected by the user from the table. That is, stop, Press the button and wait until the LED number does not flash to complete the setting. The LED number is illuminated at each keystroke and you can observe the value of the solar charge controller.
Pure light control: If there is no sunlight, the light intensity decreases below the starting point, the controller delays the start signal by ten minutes, the load is switched on and the solar charge controller starts working; In case of solar radiation, the light intensity increases at the starting point indicated above, the solar charge controller switches off the output after confirmation of the off signal after a 10-minute delay and the load will no longer work.
One-period mode of light control turns off a + delay: The start process of the solar charge controller is the same as in previous steps, when the load works for the set time, the load is switched off.
In general, the battery will be left standing for a certain period after the compensation has been completed, so that its terminal voltage will naturally decrease. If the battery voltage is low, charge it a little and charge it at low voltage one after the other to prevent the battery temperature from constantly rising. This is very good for the battery, because the internal temperature of the battery is important for charging and unloading. The effect is great. In fact, the PWM solar charge controller mainly serves to stabilise the battery terminal voltage and reduce the battery charging current by adjusting the pulse width. This is a very scientific cargo management system. Specifically, the solar charge controller must reduce the charging current if the residual capacity (SOC) of the battery at the later charging stage is > 80% in order to prevent excessive discharge (oxygen, hydrogen and oxygen) by overload.
Solar cells and LED light source technology have their place in the world, but many controllers are simple and not intelligent solar charge controllers that restrict the technical upgrading and promotion of solar street lights. Shenzhen Sumry Electronics Co., Ltd. has undertaken to increase the number of solar charge controllers and to make them more effective, reliable and consistent.
