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.
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.
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.
The device was setup and the device is working properly. It gives clear readings. The condition of the solar controller is good, the function of the solar controller is good, and there are no problems with the device.
I have a DIY solar battery backup system for my house. Uses 300 watts of solar panel and 2 sine wave inverters. In a power outage, i can run my fridge, a laptop, and my ATT fiber optic broadband service. Unlike cable broadband, the fiber broadband stays up in power outages.I have 3 conventional Group 27 batteries for energy storage, about 300 Ah. Those are 5 years old and still working for me, However, i plan to replace them with a Lithium Phosphate battery, whose price has dropped a lot in recent times. I'm tired of messing with adding water to the batteries, etc. They still are fine for the time being, but I will replace them with a LiPo battery, Given their age, I planned ahead and replaced my solar charge controller with this Li Time unit, which is easily programable for multiple battery types. It works well with my conventional storage batteries, and now I'm all set for an easy transition to LiPo batteries. This LiPo controller isn't the cheapest, but given the critical needs of Lithium batteries I thought this would be the safest best bet.
As advertised, delivery and pricing on point.
Its a good solar charge controller, I even run a ring battery camera on the USB port. It errors out when I try to use my 300 watt inverter so I run it directly off of the battery. Other smaller loads work fine and I dont need to leave the inverter on for long periods so Im more than satisfied.
Works as advertised. I Like the voltage and current displays. Needed for my lifeso4 battery and rv solar panels. I do not use the power out option.
LiTime 20Amp 12V/24V PWM Solar Charge 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
