Q:Solar water heater controller power screen is not displayed
Are many kinds of possible, the transformer is broken, the control panel no electricity, the chip is broken, the display is broken
Q:What is the power of the solar controller?
If you are 12V system, select the 10A controller, then the controller with the power of 12V × 10A = 120W, up to the battery with no more than 150W.
Q:The principle of solar controller
Solar energy is a kind of radiant energy, it must be by means of energy conversion device can be transformed into electric energy.This kind of radiant energy into energy energy conversion device, is the solar cell.C solar cell is the use of photoelectric conversion principle of the sun's radiation through the semiconductor Material conversion into electrical energy devices, this photoelectric conversion process is often called "photovoltaic effect", solar cells, also known as "photovoltaic cells." When the sunlight to the P, N type two different types of conductive semiconductor Material under the PN junction, under certain conditions, the solar radiation is absorbed by the semiconductor material to form a built-in electrostatic field.If the two sides from the built-in electrostatic field leads to the electrode and connected to the appropriate load, it will form a current, which is The basic principle of solar cells. Monolithic solar cell is a thin piece of semiconductor PN junction. Under standard lighting conditions, the rated output voltage is 0.48V. In order to obtain a higher output voltage and larger capacity, often more than one solar cells connected together , At present, the solar cell photoelectric conversion rate is generally around 15%, individual developed countries, laboratory solar cell photoelectric turn The rate has been able to reach about 30%.
Q:Solar controller can not charge what is the reason
Are charged control point voltage: direct charge after the end of the battery will be charged and discharged controller for some time, so that the voltage naturally fall, when the fall to the "recovery voltage" value, will enter the charge state. Why are they designed? That is, when the direct charge is completed, there may be individual batteries "backward" (terminal voltage is relatively low), in order to pull these individual molecules back, so that all the battery side voltage is uniform, so it is necessary to high voltage with moderate Of the current and then charge a small meeting, we can see the so-called charge, that is, "balanced charge." Are charged time should not be too long, usually for a few minutes to ten minutes, the time set too long but harmful. For a small system equipped with two batteries, it is not meaningful. Therefore, the street lamp controller is generally not full charge, only two stages
Q:What is the system voltage of the 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:Solar controller water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
Q:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
Q:What brand of solar controller is good
The State Administration of Quality Supervision, Inspection and Quarantine announced the Chinese brand-name products, the entire solar water heater industry is currently only selected eight companies, as follows: force Norit Shandong force Norit New Energy Co., Ltd. billion to Shandong billion solar energy Co., Ltd. Sunrise Oriental sun rain Lianyungang City sun rain water heater Manufacturing Co., Ltd. Huayang Jiangsu Province, Yang Yang Solar Co., Ltd. Huang Ming Shandong Huang Ming Solar Group Co., Ltd. Sang music digital Shandong Sang Le Solar Co., Ltd. Tsinghua sunshine Beijing Tsinghua sunshine solar equipment limited liability company Brilliant Jiangsu Huaiyin brilliant solar energy limited company
Q:Solar controller does not heat how to heat
This can only rely on the sun to pull. Sun drying water is not enough water, you can only install a heating tube pull! Also choose a thick power cord. Thin line not work. Control can not pass your controller, an external air switch on it.
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.
