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.
Q:Solar panels for solar panels
Solar controller is composed of dedicated processor CPU, electronic components, monitors, switching power tubes and other components.
Q:The principle of solar controller
Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.
Q:How to choose a solar controller
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 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 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 is the system voltage of the solar controller?
Solar controller battery terminal 12V battery, the load side can be directly connected to the 12V DC lamp? ----- This DC lamp, are 12V, can.
Q:How the inverter is connected to the solar controller
No, no load will not work!
Q:Solar water heater all intelligent controller how to install
This is the most widely used solar water heater installation program, the solar energy operation by the solar controller 8 control, when the solar water heater tank water level below the minimum water level, the controller to open the solenoid valve 1, making the water tank, When the water level rises to the user set the highest water level, the controller closes the solenoid valve 1, the water stops. The user can specify the water time, when the specified time to, as long as the water level does not exceed the maximum water level, the controller will open the solenoid valve 1 water until the water level to the highest water level. The controller can also manually force the water: When the manual water key is pressed, the controller opens the solenoid valve until the water level reaches the highest water level.
Q:What brand of solar controller is good
Above these products are also good quality, your problem is the price, which the highest? This is mainly to see the local dealer pricing, and some require profit is not high, the price is cheap; some require high profits, the price is expensive. So I put these products and then divided into 369 and so on, give you a quality reference, you go and dealers brave bargain go. Best: Tsinghua sunshine (in addition to fast music series), Emperor Ming, billion Canon. General: Hua Yang, Qunlang, Sang Le, brilliant, sun rain, four seasons Mu bad: Tian Pu. Disclaimer: I am not above any of the company's employees, our company's products can also, the price is cheaper than them, our retailers do not know where you are there.
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
