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:How to choose a solar controller
Of course, you need other features, then it is necessary to say your needs, such as when the battery is not electricity you have to load to work, you can have electricity complementary controller; you want the lights in the first 5 hours Full power, midnight midnight power, then you have to choose with half the power of the controller; you need to light from heaven to 0:00, 0:00 automatically shut down the load, 4:00 and bright until dawn, you can choose double Of the controller
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
Battery status indication: When the battery voltage is in the normal range, the status indicator (2) is green; if the status indicator is green slow flashing; when the battery voltage drops to undervoltage, the status indicator turns orange; when the battery When the voltage continues to decrease to the overdischarge voltage, the status indicator (2) turns red, and the controller will automatically turn off the output to remind the user to replenish the power in time. When the battery voltage returns to the normal operating range, the output enable action will be automatically enabled and the status indicator (2) will turn green;
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:How does the solar controller set up Sheung Shui?
Press and hold the warm water temperature button for 3 seconds, hear the "drop" after the sound, the display temperature of the two digital and "regular heating" indicator light began to flash, press the heating water temperature key to set the time heating time The Set the time in Beijing plus the set number of hours is the timing of the heating time, such as set at 10 am, regular heating at 4 pm every day, then set the number of hours 06 (range 00-23), wait 5 seconds to automatically save the exit "regular heating" light is always bright, the heating effect of the deadlock, after 4 pm every day will automatically heat up regularly. Cancel the regular heating, according to "heating water temperature" between 3 seconds, hear the "drop" after the "regular heating" indicator off, the timing heating function is canceled.
Q:What is a solar controller?
The controller is the microcomputer on the water valve above the show solar water tank temperature control Sheung Shui to a certain level of electronic valve will automatically shut down the water is not on the water level to the most electronic valve will automatically open the solar water tank temperature is higher than 75 degrees above the water tank That is, no water, the electronic valve will not open to avoid solar vacuum tube break
Q:Solar controller does not heat how to heat
Solar energy itself is the hot water of the stuff, certainly can be heated, but not with electric heating only.
Q:What are the solar controller models?
The controller is 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 chip on the battery terminal voltage, discharge current, ambient temperature and other parameters related to the battery capacity of the sample, through the special control model calculation, 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: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.
