- 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:What is the meaning of the DC load above the solar controller?
- Solar power systems are generally DC storage, of course, there are grid-connected power generation, the output is AC, but this system is still relatively small in the country, especially for some small systems. If it is a solar street light system,
- 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.
- 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: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:What brand of solar controller is good
- Professional to do solar energy, such as imperial Ming, Sang Le, sun rain, force Norit and so on
- Q:What is a 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 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: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;
