Q:What is the meaning of the 30A solar controller?
Control the superscript of the current should be in accordance with the rated current to the target, rather than the maximum current. That is: the other side of the discharge or charge when the rated current is 30A. If you explain the controller is the maximum current, the basic is substandard products.
Q:What brand of solar controller is good
Do you ask the controller for photovoltaic power generation?
Q:How the solar panels with the controller
Solar controller mode: 1, 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 set the parameters to open the load, the load began to work; when there is sunlight , The light intensity rises to the starting point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load to stop working.
Q:What are the solar controller models?
You that the controller is the manufacturer, go to their website under the instructions can be
Q:What is the power of the solar controller?
For example: 12V10A controller, then the solar panel over the current is not more than 10A, the solar panel power is not more than 120W, useful DC load, then the DC load is not more than 80W
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: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:How to debug a solar street light controller
Pure light control (0): When there is no sunlight, the light intensity drops 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 to start Point, the controller delay 10 minutes to confirm the closure of the signal after the closure of the output, the load stops working.
Q:Solar controller red light flashing
Red light on behalf of the system failure, the specific failure is what depends on the controller manufacturer how to set, the general failure are: undervoltage, overvoltage, overload, short circuit, over temperature and so on.
Q:Solar controller one machine how
You should include a charge and inverter as one of the machines. This product is also very good, but for many users is not very applicable, such as I hope to enter the input, but the output power can not meet, and configure the inverter is more waste. If your needs and configuration just right, it is still relatively easy to use. The cost of the above is higher.
