Q:Solar water heater controller power screen is not displayed
Are many kinds of possible, the transformer is broken, the control panel no electricity, the chip is broken, the display is broken
Q:Solar panels for solar panels
Using the series PWM charging the main circuit, so that the charging circuit voltage loss than the use of diode charging circuit reduced by nearly half, the charging efficiency of 3% -6% higher than non-PWM, increased power consumption; over discharge recovery to enhance the charge, Normal direct charge, float the automatic control mode so that the system from a longer life; at the same time with high precision temperature compensation; intuitive LED LED indicates the current battery status, allowing users to understand the use of the situation; all control all use industrial chip ( Only with I industrial controller), in the cold, high temperature, humid environment to run freely. At the same time the use of crystal timing control, timing control accuracy.
Q:What is the power of the solar controller?
The solar controller is represented by the maximum available current
Q:Solar controller can not charge what is the reason
Overdischarge protection Termination voltage: This is better understood. Battery discharge can not be lower than this value, which is the provisions of the national standard. Although the battery manufacturers have their own protection parameters (standard or line standard), but ultimately to close to the national standard. It should be noted that, for safety reasons, the general 12V battery over the protection point voltage plus 0.3v as a temperature compensation or control circuit zero drift correction, so 12V battery over discharge protection voltage is: 11.10v, then 24V system over discharge protection point voltage is 22.20V. At present, many manufacturers of charge and discharge controller are used 22.2v (24v system) standard.
Q:How the inverter is connected to the solar controller
What are your requirements, the inverter is the battery
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:Solar controller use
And then anti-backlash protection, short circuit protection, overcharge and over discharge protection
Q:What brand of solar controller is good
Professional to do solar energy, such as imperial Ming, Sang Le, sun rain, force Norit and so on
Q:What are the solar controller models?
This situation is best to contact the manufacturers, generally have PDF version of the manual. You can contact the manufacturer to an electronic version of the manual.
Q:How the solar controller wiring,
Controller (English name: controller) refers to the order in the order to change the main circuit or control circuit wiring and change the circuit resistance value to control the motor start, speed, braking and reverse the master device. It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. It is a "decision maker" that issues a command to complete the coordination and command of the operation of the entire computer system.
