LiTime 20Amp 12V/24V PWM Solar Charge Controller

Q: What is the main difference between MPPT and PWM charge controllers?

The main difference is in how they regulate the charging process. MPPT controllers track the maximum power point of the solar array to extract the most power, while PWM controllers simply regulate the voltage to the battery. Can read on MPPT VS PWM for more information.

Q: What are the advantages of using a PWM solar controller?

PWM controllers are cost-effective, simple to use, and reliable. They are suitable for smaller solar power systems and are generally more affordable compared to MPPT (Maximum Power Point Tracking) controllers.

Q: Can a PWM solar controller be used with different types of batteries?

Yes, PWM controllers are compatible with various types of batteries, including lead-acid, gel, and AGM (Absorbent Glass Mat) batteries. They are designed to adjust the charging parameters based on the connected battery type.

REVIEWS

LiTime 20Amp 12V/24V PWM Solar Charge Controller

Simple solar controller

Purchased this controller for an auxiliary solar panel. Mounted the controller and plug inside of a large battery box.

in my test setup it worked great, waiting for a real world test latter

in my test setup it worked great, waiting for a real world test latter

Unbeatable for the price

Admittedly I bought it on sale and it's only PWM, but seriously, a 20A charge controller that displays everything that's happening (including PV voltage & current and battery voltage and current) and is programmable for both Li and Lead-acid batteries for this price is a genuine bargain. I have only used it for a couple of hours so far, but it's performing exactly how one would hope. And it can handle my two 100W panels in either series or parallel. I'm very favorably impressed.

Perfect for the small project

It has all the information you need on the display and also you can turn ON/OFF your Load.
