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:What is the system voltage of the solar controller?
Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell battery charging and battery to the solar inverter load power supply automatic control equipment.
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: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:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
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?
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
The above heating of the controller is in the absence of the sun and you need to use hot water to add, so that you can use hot and cold weather.
Q:How the solar controller wiring,
Open the panel below the lid, which has a post, there are marked, facing the annotation is what to pick on the line!
