Q:How to choose a solar controller
The choice of solar street light controller, generally in accordance with the current, and the current mainly depends on the battery power and battery voltage ratio and the load power with the battery voltage ratio, who take those who, such as the load is 60W, battery with 100W, battery Voltage 12V, 60W / 12V = 5A, 100W / 12V = 8.333A, so choose 12V10A solar controller
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:What are the solar controller models?
Pure light control mode: when there is no sunlight, the light intensity dropped to the starting point, the controller delay 10 minutes to confirm the start signal, according to the set parameters to open the load, the load began to work; when there is sunlight, light intensity rose to the starting point, The controller delays 10 minutes after confirming the shutdown signal and turns off the output. The load stops working. Light control + time control mode: start the same process and pure light control, when the load to set the time to automatically shut down, set the time 1 to 14 hours. Manual mode: In this mode, the user can press the button to control the load on and off, regardless of whether the day or night. This mode is used for some special load or debug mode when used in debugging: for system debugging, when the optical signal is closed, no light signal load, easy installation and commissioning check the correctness of the system installation. Normally open mode: The power-on load remains in the output state, which is suitable for 24-hour power supply.
Q:Solar water heater controller power screen is not displayed
May be the screen power supply circuit is broken, it is best to ask the professional repair under.
Q:How to adjust the solar controller
The controller through the computer chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity of the sample, through the special control model calculation, to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy rate control , And adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
Q:Solar controller 10a, a represents what
A, represents the current. Indicates the current that is allowed to pass during operation of the controller.
Q:Choose a solar controller which need to have a few conditions
And some electrical function must be necessary. In one is from the manufacturer, the best choice of more formal relatively large manufacturers, and now the market is too messy. Stability is one, after the sale is also a.
Q:How the solar panels with the controller
Battery status indication: When the battery voltage is in the normal range, the status indicator (2) is green; if the status indicator is green slow flashing; when the battery voltage drops to undervoltage, the status indicator turns orange; when the battery When the voltage continues to decrease to the overdischarge voltage, the status indicator (2) turns red, and the controller will automatically turn off the output to remind the user to replenish the power in time. When the battery voltage returns to the normal operating range, the output enable action will be automatically enabled and the status indicator (2) will turn green;
Q:Solar controller use
The role of the controller is used to protect the battery from overdischarge. Cloudy charge current is small when there is no boost function
Q:What is the use of solar controller
Perfect protection: electrical protection reverse, short circuit, overcurrent and so on.
