Q:The principle of solar controller
Principle: solar panels are photovoltaic equipment (the main part of the semiconductor material), it occurs after the light generated by the photoelectric effect of current. Supplement: the role of solar controller: control the work of the entire system state, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switches, time control switches should be optional controller.
Q:Solar controller can not charge what is the reason
Overdischarge protection Termination voltage: This is better understood. Battery discharge can not be lower than this value, which is the provisions of the national standard. Although the battery manufacturers have their own protection parameters (standard or line standard), but ultimately to close to the national standard. It should be noted that, for safety reasons, the general 12V battery over the protection point voltage plus 0.3v as a temperature compensation or control circuit zero drift correction, so 12V battery over discharge protection voltage is: 11.10v, then 24V system over discharge protection point voltage is 22.20V. At present, many manufacturers of charge and discharge controller are used 22.2v (24v system) standard.
Q:What is a solar controller?
Solar controller is used to control the charge and discharge and has a reverse charge protection, overcurrent protection, overload protection, short circuit protection, digital display parameters and other functions of electronic equipment. To select a solar controller, it is recommended to choose from the ENF website. Which includes the well-known domestic and foreign manufacturers of information and product information. Under normal circumstances the controller has waterproof protection measures. To choose according to different needs
Q:What is the power of the solar controller?
Generally in accordance with the current to count. Depending on your system voltage, such as 12V or 24V
Q:How to choose a solar controller
Hongyi HY-12 / 24V10A solar controller designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings.
Q:Choose a solar controller which need to have a few conditions
According to your specific application environment, first determine whether to select the charge controller or charge and discharge controller. Two applications of input and output power level, the input power is mainly solar panels, and the controller is basically in accordance with the current to count. For example, 12V system 120 wrench that should be selected at least rated 10A controller. While the actual system current 7A or so is the other security margin.
Q:How to adjust the solar controller
The controller is designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings. With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions.
Q:Solar controller water level display is not correct how to do
If not explain the control board or tube water level sensor bad, consider, for reference!
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
As long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
Q:Solar controller one machine how
You should include a charge and inverter as one of the machines. This product is also very good, but for many users is not very applicable, such as I hope to enter the input, but the output power can not meet, and configure the inverter is more waste. If your needs and configuration just right, it is still relatively easy to use. The cost of the above is higher.
