Q:Solar controller 10a, a represents what
10A indicates that it can control the maximum current is 10 amps, the use of the load can not be greater than this current.
Q:What is the meaning of the DC load above the solar controller?
Can be batteries, lights, motors and other DC equipment can be used
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 to adjust the solar controller
Charging and overpressure indication: When the system is connected normally and the sun is exposed to the photovoltaic panel, the charging indicator (1) is green, indicating that the system charging circuit is normal; when the charging indicator (1) Description of the system over-voltage, the treatment see the fault handling content; charging process using the PWM method, if there have been over-discharge action, the charge must first increase the charging voltage, and keep 10 minutes, and then down to the direct charge voltage, Live activation of the battery, to avoid sulfide crystallization, and finally dropped to the float voltage, and keep the float voltage. If there is no over-discharge, there will be no way to enhance the charge to prevent the battery water loss. These automatic control processes will allow the battery to achieve the best charging effect and to ensure or extend its service life.
Q:How the solar panels with the controller
Hong-wing HY-12 / 24V10A solar street light controller designed for solar DC power supply system, solar DC street lamp system design, and the use of a dedicated computer chip intelligent controller. Use a one-touch touch switch to complete all operations and settings. With full short-circuit, overload, unique anti-reverse protection, full, over-automatic shutdown, recovery and other full-function protection measures, detailed charge instructions, battery status, load and a variety of fault instructions. The controller through the computer core search chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity sampling, calculated by a dedicated control model to achieve the characteristics of the battery discharge rate, temperature compensation correction of high efficiency, high accuracy Rate control, and adopted a high efficiency PWM battery charging mode, to ensure that the battery work in the best condition, greatly extending the battery life. With a variety of work patterns, output mode selection, to meet the various needs of users.
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:What is a solar controller?
Can control the solar street light, the switch controller is the solar controller; domestic well-known brands should be far away power and the exchange of energy to the sun in the science and technology in Beijing; we are the power to do LED lighting business is brand goods
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:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
As long as the voltage is 12V, with more power battery panels can be affected only the problem of charging speed.
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.
