Properties of the solar charge controller
1. Design for off-grid solar power system.
2. Applicable to different kinds of batteries.
3. Adopts MPPT technology (Maximum Power Point Tracking). The advanced tracking algorithm make the solar module operate at ideal voltage which the solar modules can produce the maximum available power.
4. Modular design with simple structure and easy maintenance.
5. Automatic power control function.
6. LCD display: Solar panel current, solar panel voltage, solar panel power, battery group voltage, charge current.
7. Perfect protection function: Solar reverse charge protection, Solar reverse connection protection, Battery reverse connection protection, Battery overcharge protection, Battery over current protection etc ,thus the system has higher reliability.

- Q:Solar panels for solar panels
- Solar controller is composed of dedicated processor CPU, electronic components, monitors, switching power tubes and other components.
- Q:Solar controller 10a, a represents what
- In addition, the general controller will be marked as single-phase or three-phase power, according to P = UI (power = voltage * current) this formula, you can infer the corresponding power, in the choice of output devices (such as pumps) can not exceed this power.
- Q:What is the power of the solar controller?
- The solar controller is represented by the maximum available current
- Q:How to choose a solar controller
- Of course, you need other features, then it is necessary to say your needs, such as when the battery is not electricity you have to load to work, you can have electricity complementary controller; you want the lights in the first 5 hours Full power, midnight midnight power, then you have to choose with half the power of the controller; you need to light from heaven to 0:00, 0:00 automatically shut down the load, 4:00 and bright until dawn, you can choose double Of the controller
- 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!
- Q:What is the meaning of the 30A solar controller?
- This 30A proves that the controller has a maximum current of 30A.
- Q:How does the solar controller set up Sheung Shui?
- Press and hold the water level key for 3 seconds, hear the "drop" sound, the display temperature of the two digits and the "time to add water" indicator light at the same time flashing, repeat the water level key to set the time to add water time. Set the time in Beijing plus the number of hours set into the regular water, such as set at 12 o'clock in the hour, regularly at 8 o'clock every day on the water, set the number of hours 20 (range 00-23), wait 5 seconds to automatically save and exit the "regular water" indicator light is on, the regular water function takes effect, after 8 o'clock every day will start the regular water. To cancel the time to add water: hold the water level key for 3 seconds, hear the "drop" after the "time to add water" indicator off, the time to add water function to cancel.
- Q:Solar controller does not heat how to heat
- Solar energy itself is the hot water of the stuff, certainly can be heated, but not with electric heating only.
- 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.
- Q:Choose a solar controller which need to have a few conditions
- The controller should have battery overvoltage protection, battery undervoltage protection, load short circuit protection, temperature compensation and other functions, select the controller to choose the quality of the guarantee. Big manufacturers big brand
