Q:The principle of solar controller
In fact, is a power management. Solar controllers are divided into different types of applications, but are basically controlled by solar charging and battery discharge management.
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: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:Solar controller red light flashing
Installation of the controller should pay attention to: 1, waterproof; some of the controller on the market is not easy to produce waterproof, easy to penetrate the water vapor in the poles, resulting in short circuit and other issues; 2, pay attention to the controller and system rationality, 3, the main function of the controller is to protect the battery, must pay attention to.
Q:How the solar panels with the controller
Hong-wing HY-12 / 24V10A solar street light 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. 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. The controller through the computer core search chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity sampling, calculated by a dedicated control model 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: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:Solar controller 10a, a represents what
A (Ampere) is the basic unit of current expressed in the International System of Units, referred to as Ann, Symbol A. 10A refers to the controller can control the output device maximum current of 10A, select the load device when the device current can not exceed this value
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
Q:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
Q:Solar water heater controller power screen is not displayed
The transformer is broken; the control panel is not powered; the chip is broken; the display is broken. Solar water heater is the solar energy into heat energy device, the water from low temperature heating to high temperature, to meet people in life, the production of hot water use. Solar water heaters according to the structure is divided into vacuum tube solar water heaters and flat solar water heaters, mainly in the vacuum tube solar water heater mainly occupy 95% of the domestic market share. Vacuum tube type household solar water heater is composed of heat pipe, storage tank and bracket and other related parts, the solar energy into heat mainly rely on vacuum tube, vacuum collector tube using hot water floating cold water sink principle, the water microcirculation To achieve the required hot water.
