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 controller red light flashing
Solar controller flashing red light according to the different brands of the representative of the meaning of the controller are not the same, but in general terms, the red light flashing a saying that the battery is charging the battery is expressed as a red light flashing, green , The yellow light does not shine; another kind is the battery high pressure state or battery low voltage state that is red light flashing, green light does not light, hope to help you
Q:How to choose a solar controller
Of course, you need other features, then it is necessary to say your needs, such as when the battery is not electricity you have to load to work, you can have electricity complementary controller; you want the lights in the first 5 hours Full power, midnight midnight power, then you have to choose with half the power of the controller; you need to light from heaven to 0:00, 0:00 automatically shut down the load, 4:00 and bright until dawn, you can choose double Of the controller
Q:Solar panels for solar panels
Using the series PWM charging the main circuit, so that the charging circuit voltage loss than the use of diode charging circuit reduced by nearly half, the charging efficiency of 3% -6% higher than non-PWM, increased power consumption; over discharge recovery to enhance the charge, Normal direct charge, float the automatic control mode so that the system from a longer life; at the same time with high precision temperature compensation; intuitive LED LED indicates the current battery status, allowing users to understand the use of the situation; all control all use industrial chip ( Only with I industrial controller), in the cold, high temperature, humid environment to run freely. At the same time the use of crystal timing control, timing control accuracy.
Q:What is the meaning of the DC load above the solar controller?
Solar power systems are generally DC storage, of course, there are grid-connected power generation, the output is AC, but this system is still relatively small in the country, especially for some small systems. If it is a solar street light system,
Q:What is the system voltage of the solar controller?
The system voltage is the voltage you use the battery, such as 12V or 24V. According to your overall configuration, if your battery is a working voltage of 18V, then the system voltage can only use 12V, 36V is used on the 24V.
Q:What is the meaning of the 30A solar controller?
Control the superscript of the current should be in accordance with the rated current to the target, rather than the maximum current. That is: the other side of the discharge or charge when the rated current is 30A. If you explain the controller is the maximum current, the basic is substandard products.
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
In fact, as long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
Q:Solar controller use
The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
Q:How the solar controller wiring,
Power cord - usually with the controller with a three-pin plug power cord, has a good controller; sensor line - two lines and four lines, according to the label with a plug or terminal connected to the controller; solenoid valve - Two, according to the label connected to the controller; electric auxiliary heating line - three, according to the label connected to the heating bar.
