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
Float control point voltage: the general charge is completed, the battery is also standing for some time, so that the end voltage naturally fall, when the drop to the "maintenance voltage" point, it entered the float state, are currently using PWM (both Pulse width modulation), similar to the "trickle charge" (that is, a small current charge), a low battery voltage to charge a little, a low charge on the point, an share of a place to avoid the battery temperature continues to rise, This is very good for the battery, because the internal temperature of the battery charge and discharge a great impact. In fact, the PWM method is mainly designed to stabilize the battery terminal voltage, by adjusting the pulse width to reduce the battery charge current. This is a very scientific charge management system. Specifically, at the end of the charge, when the remaining capacity of the battery (SOC)> 80%, it is necessary to reduce the charging current to prevent excessive release (oxygen, hydrogen and acid gas) due to overcharging.
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 one machine how
Built-in high-precision step-up constant current source, no need to reprovision LED constant current source, can directly drive LED lamp beads, single string up to 18, up to 9 groups in parallel, the output power can reach 160W, to meet all the market LED street lamps;
Q:What brand of solar controller is good
Professional to do solar energy, such as imperial Ming, Sang Le, sun rain, force Norit and so on
Q:Solar water heater all intelligent controller how to install
The controller can also control the electric heating. When the electric heating key is pressed, the controller turns on the power of the electric heater 7 and the electric heater operates until the user specifies the temperature. When the temperature drops below the specified temperature 3-5 degrees, the controller restarts the electric heating and heats the water to the specified temperature. Users can also specify the heating time, at a time, the temperature of the solar water tank can not reach the set temperature, the controller will turn on the electric heater, the water tank to the water set to the temperature so far. The controller also has a protective effect, and when the water level drops to a certain point, the electric heating stops until the water level rises above that point. (Usually 50% of the water level).
Q:How to adjust the solar controller
Solar controller mode: 1, 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 set the parameters to open the load, the load began to work; when there is sunlight , The light rises to the start point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
Q:What is the meaning of the DC load above the solar controller?
Lamp or load class is DC DC12V / 24V / 36V / 48V, etc. If you want to AC load AC220V lamps or other, you need to add a DC-AC inverter in the middle.
Q:Choose a solar controller which need to have a few conditions
To buy a solar controller must know the power of the solar panel and the load power to be used to determine the controller's charging current and discharge current. General solar controller are 12v / 24v automatic identification. Discharge current = load power / 12v, charge current = battery power / battery board voltage. The voltage of the panel can be set with the multimeter DC. The short-circuit current of the panel uses a clamp meter to test the current. So the battery power = voltage * current, basically know the power of the solar panel. The battery charge current will know. The current range of the controller is greater than the charging current of the solar panel and the discharge current of the load.
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.
