Q:Solar water heater controller power screen is not displayed
May be the screen power supply circuit is broken, it is best to ask the professional repair under.
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?
Because the controller output function, such as the switch, then the battery is DC energy, so if the direct output, can only take the DC load, can work properly, if you want to work on the AC load, then the need to connect the controller output DC Inverter, so that the AC load can work. My space has a lot of information about the solar system, welcome to come to view
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: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
At present, the general 12V inverter is not 2000W. Solar controller separation network and grid, do not know what you say.
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 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.
Q:What is a solar controller?
Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell array on the battery charging and battery to the solar inverter load power supply automatic control equipment
Q:Choose a solar controller which need to have a few conditions
The controller should have battery overvoltage protection, battery undervoltage protection, load short circuit protection, temperature compensation and other functions, select the controller to choose the quality of the guarantee. Big manufacturers big brand
