Q:What is the power of the solar controller?
If you are 12V system, select the 10A controller, then the controller with the power of 12V × 10A = 120W, up to the battery with no more than 150W.
Q:Solar controller can not charge what is the reason
Direct charge protection point voltage: direct charge also called emergency charge, are fast charge, are generally in the battery voltage is low when the use of high current and relatively high voltage on the battery charge, but there is a control point, also known as protection points, Is the value in the table above, when charging the battery terminal voltage higher than the protection value, should stop charging. Direct charge protection point voltage is generally "overcharge protection point" voltage, the battery voltage when charging the battery can not be higher than the protection point, otherwise it will cause overcharge, the battery is damaged
Q:What is the system voltage of the 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 water level display is not correct how to do
Re-adjust the water level to control, choose their own water.
Q:How the inverter is connected to the solar controller
No, no load will not work!
Q:Solar controller use
The controller as a core component of solar energy must be a reliable product, otherwise no matter how good the solar system can not play its due role.
Q:What is the meaning of the 30A solar controller?
The maximum current is 30A
Q:What brand of solar controller is good
Do you ask the controller for photovoltaic power generation?
Q:How does the solar controller set up Sheung Shui?
Click the timer key, there are addition and subtraction keys can be set, the specific I did not use Norit big, do not know, you still consult their customer service department, the instructions should also have.
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.
