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
100w of the battery plate count down one day also saved the estimated electricity will be able to use the battery on the market are 12v inverter is definitely 12vdc turn 220ac solar controller this thing looks like no, at most, a switch has been controlled whether Output power. The specific needs of the number of A / h battery pack you calculate it yourself
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:How to choose a solar controller
And you have this system has two loads, you want to separate the controller, you can choose a dual controller! And so on and so on, more details can be consulted with me
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: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:How the solar panels with the controller
Light control on + delay off - open delay + light control off the double time mode: the work process is open when the dark load (light control on), delay to set the first time after the closure of the load, turn off the load After the day until the day before the set of the second time to open the load again, to the dawn when the load off (light control off), the night when the load is closed to save power. The controller uses fuzzy control to automatically identify and effectively correct the darkness to the dawn of the entire night time, that is, according to the length of the night to automatically adjust the time to close the load at night to ensure that the load only in the dark and before dawn Set the time period to open, the other time is closed.
Q:Solar controller one machine how
First of all, if you are using a multifunctional VRV system, triple the (air conditioning, to warm, hot water) together, then connect the solar energy, solar energy is auxiliary equipment, can not be set as the main control equipment. Finally, I would like to ask, your one machine is a computer or I said one machine
Q:What brand of solar controller is good
In today's solar industry, brand-name products in terms of quality to after-sales service, are guaranteed. And consumers want to compare through their own observation to choose, there are some difficulties. Such as the key components of solar water heaters is the insulation of the tank and the material and thickness of the liner steel, only the water tank can be destroyed before the amount of liner thickness and material. There is the quality of the vacuum tube, these things even if our industry people, without destroying the product, do not use precision instruments in the case, can not be identified
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
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.
