- 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 debug a solar street light controller
- Debug mode (6 ·): used for system debugging, when the optical signal is closed load, no light signal load, easy installation and commissioning check the correct installation of the system. Normally open mode (7 ·): The power load remains in the output state, which is suitable for 24 hours power supply.
- 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 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 the solar controller wiring,
- Controller (English name: controller) refers to the order in the order to change the main circuit or control circuit wiring and change the circuit resistance value to control the motor start, speed, braking and reverse the master device. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision maker" that issues a command to complete the coordination and command of the operation of the entire computer system.
- Q:Choose a solar controller which need to have a few conditions
- According to your specific application environment, first determine whether to select the charge controller or charge and discharge controller. Two applications of input and output power level, the input power is mainly solar panels, and the controller is basically in accordance with the current to count. For example, 12V system 120 wrench that should be selected at least rated 10A controller. While the actual system current 7A or so is the other security margin.
- Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
- Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell battery charging and battery to the solar inverter load power supply automatic control equipment.
- Q:How the inverter is connected to the solar controller
- The controller combines the logic controller and the microprogram controller, both of which have strengths and weaknesses. The combination of logic controller design trouble, complex structure, once the design is completed, can not be modified or expanded, but it is fast. Microprogram controller is easy to design, simple structure, modify or expand are convenient, modify the function of a machine instruction, just repeat the corresponding micro-program; to add a machine instruction, just add a micro-program in the control memory, However, it is done by performing a short process. The specific comparison is as follows: Combination logic controller, also known as hard-wired controller, composed of logic circuit, completely by hardware to achieve the function of the instruction.
- Q:What is a solar controller?
- Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell array on the battery charging and battery to the solar inverter load power supply automatic control equipment
- Q:Solar controller water level display is not correct how to do
- If not explain the control board or tube water level sensor bad, consider, for reference!
