Q:What brand of solar controller is good
Do you ask the controller for photovoltaic power generation?
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:How to choose a solar controller
And you have this system has two loads, you want to separate the controller, you can choose a dual controller! And so on and so on, more details can be consulted with me
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 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:Solar controller 10a, a represents what
A (Ampere) is the basic unit of current expressed in the International System of Units, referred to as Ann, Symbol A. 10A refers to the controller can control the output device maximum current of 10A, select the load device when the device current can not exceed this value
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:How to debug a solar street light controller
Light control + time control (1 ~ 4 ·): start the same process and pure light control, when the load to the set time to automatically turn off, set the time 1 to 14 hours.
Q:What is the system voltage of the solar controller?
The system voltage is the voltage you use the battery, such as 12V or 24V. According to your overall configuration, if your battery is a working voltage of 18V, then the system voltage can only use 12V, 36V is used on the 24V.
Q:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
