Overview

PWM solar charge controller rated charge controller current 30A, DC 12V/24V Auto intelligence, USB output, backlight design, low light can also be used.


Features

  1. The left button is not affected by the wiring position, and the operation is convenient. The button is separated from the USB left and right to prevent the data line from being loosened when the button is operated to prevent equipment damage. Easy to operate, saves setup time.
  2. The chip of PWM controller 24v has data logging and storage capabilities. The improvement of the position of the terminal prevents the current from being backflushed and burning out the controller, and also protects the battery, making the PWM solar controller's charging process safer.
  3. The PWM charge controller screen comes with a backlight function. Just click any button and the screen will light up, which is convenient for the night or low light.
    2.0A USB output interface for faster charging. Solve the troubles of customers' mobile phones or electronic devices.

FAQ

What are the protection mechanisms of PWM solar controllers?

PWM solar controllers also have a variety of protection mechanisms to ensure the safety and efficiency of the charging process:

  1. Overvoltage protection: When the battery voltage exceeds the set value, the PWM solar charge controller will automatically cut off the charging power supply to prevent the battery from overcharging.
  2. Over-discharge protection: When the battery voltage is lower than the set value, the PWM controller will take measures to prevent the battery from over-discharging.
  3. Short-circuit protection: In the event of a short-circuit fault, the PWM controller 12v will immediately cut off the charging power supply to protect the safety of the circuit and equipment.
  4. Reverse connection protection: If the positive and negative poles of the solar power panel or battery are reversed, the PWM controller 24v will automatically identify and take measures to prevent damage.

Great budget-friendly controller.
The 30 Amp PWM solar charge controller is a solid pick for off-grid setups at this price. The auto switch between 12V and 24V is super convenient, and the LCD is easy to read. While it’s not as efficient as MPPT controllers, it gets the job done for smaller systems.

Solid solar charge controller with great protection features!
I’ve been using the 30amp pwm solar charge controller for my off-grid setup, and it works well. The auto switch between 12V and 24V is super convenient, and the digital LCD makes everything easy to monitor. Plus, the built-in protection against overcurrent and short circuits is also good. Great value for the price!

The solar charge control is solid and I am very satisfied
With these features of the solar controller, I can see how many amps are going into my solar panels to charge my batteries. I like overvoltage, I don't use the load side. The solar controller screws are tough enough to hold securely on top of the solar panel.

I was surprised by the efficiency of the charge controller
Through my search, I came across this 30 amp PWM charge controller, in short, it works great, I am amazed at its efficiency, and shipping to California is not required, the controller is perfect for not only beginners but also dedicated and experienced engineers!

Easy and fast setup
There is a digital display on the screen. All I want is a basic controller that rarely goes wrong, so this one (so far) seems like a good cheap option.

Use of 30 Amp solar charge controller
Can i use the usbs to transfer data from the 30Amp solar charge controller to something else?
