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:Solar controller one machine how
Built-in high-precision step-up constant current source, no need to reprovision LED constant current source, can directly drive LED lamp beads, single string up to 18, up to 9 groups in parallel, the output power can reach 160W, to meet all the market LED street lamps;
Q:Solar water heater all intelligent controller how to install
Different solar water heater brand, the controller used is not the same. But the total is divided into the next type and side of the two, if you understand the installation of solar energy can first look at the probe to stay and then install the mouth. If you do not know you only looking for solar manufacturers aftermarket.
Q:Solar controller red light flashing
Look at the flash of red light shows what is the logo, the general controller should be a bad flash line
Q:What is the meaning of the DC load above the solar controller?
Solar controller, there are two major functions, one is used to charge the battery, this is the solar input function. One for the battery discharge, this is the output function. Used to charge is to prevent the electric overshoot is too full, the battery charge bad. Used to discharge is to prevent the discharge too much, the battery damage. Because the battery can not overshoot, too. Discharge, it depends on what the load discharge
Q:What is the use of solar controller
Communication function. ① simple instructions function; ② protocol communication functions, such as RS485 Ethernet, wireless and other forms of background management;
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
In fact, as long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
Q:Solar controller use
The biggest use of solar controllers is to protect the battery
Q:How the inverter is connected to the solar controller
No, no load will not work!
Q:How the solar controller wiring,
Carefully follow the instructions on the wiring
