- Q:Solar panels for solar panels
- Cancel the potentiometer to adjust the control set point, and the use of E-side memory records the work of the control point, so that set the digital, eliminating the potential deviation due to potentiometer, temperature drift, so that the control point error reduction accuracy, reliability Factor; use of digital LED display and settings, one-button operation to complete all settings, the use of extremely convenient and intuitive role is to control the work of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
- 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:Solar controller can not charge what is the reason
- Float control point voltage: the general charge is completed, the battery is also standing for some time, so that the end voltage naturally fall, when the drop to the "maintenance voltage" point, it entered the float state, are currently using PWM (both Pulse width modulation), similar to the "trickle charge" (that is, a small current charge), a low battery voltage to charge a little, a low charge on the point, an share of a place to avoid the battery temperature continues to rise, This is very good for the battery, because the internal temperature of the battery charge and discharge a great impact. In fact, the PWM method is mainly designed to stabilize the battery terminal voltage, by adjusting the pulse width to reduce the battery charge current. This is a very scientific charge management system. Specifically, at the end of the charge, when the remaining capacity of the battery (SOC)> 80%, it is necessary to reduce the charging current to prevent excessive release (oxygen, hydrogen and acid gas) due to overcharging.
- 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 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 water heater all intelligent controller how to install
- Different manufacturers are not the same, you can call to contact after-sales processing
- 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
- Above these products are also good quality, your problem is the price, which the highest? This is mainly to see the local dealer pricing, and some require profit is not high, the price is cheap; some require high profits, the price is expensive. So I put these products and then divided into 369 and so on, give you a quality reference, you go and dealers brave bargain go. Best: Tsinghua sunshine (in addition to fast music series), Emperor Ming, billion Canon. General: Hua Yang, Qunlang, Sang Le, brilliant, sun rain, four seasons Mu bad: Tian Pu. Disclaimer: I am not above any of the company's employees, our company's products can also, the price is cheaper than them, our retailers do not know where you are there.
- Q:Solar controller does not heat how to heat
- This can only rely on the sun to pull. Sun drying water is not enough water, you can only install a heating tube pull! Also choose a thick power cord. Thin line not work. Control can not pass your controller, an external air switch on it.
