It continuously tracks the maximum power point of the array to obtain maximum power to charge the battery. The tracking efficiency is no less than 99% and the peak conversion efficiency is up to 98%. It is the perfect charging solution even in cloudy environments where the maximum power point of the solar panel fluctuates throughout the day.
- 【Multiple Electronic Protections】The controller protects your system with self-diagnostic features that evaluate and protect against reverse polarity, battery overcharge, battery overdischarge, overload, short-circuit, TVS lightning protection, over-power protection, over-temperature protection, and reverse current protection. It helps to charge the battery quickly even in less than ideal weather conditions (e.g. cloudy and rainy days).
- 【Automatically Recognize 12V/24V Voltage】Automatically recognize 12V or 24V DC system voltage, compatible with all kinds of deep cycle batteries: sealed, gel, submerged and lithium batteries.

I bought this charge controller (40A model) for my 800W back yard solar setup. It has worked well and keeps the batterrry bank topped up all the time. The readouts are simple and easy to understand. It pushes 30+ amps every day with no problems. When the fans come on they are very quiet. A good unit.

I have a small 8 panel 800 watt solar array and two 12 volt 100 amp hour lithium LiFePO4 batteries so this controller is perfect.
The LCD display is easy to read and informative. It’s keeping my batteries at 100% charge after only a few hours of sun.
So far it remained very stable in all kinds of weather (it’s located in an outdoor cabinet) and remains cool.
One important caveat – the unit automatically selected gel cell batteries instead of lithium so I had to go in and change that parameter – which was easy and only took a minute.

Nice little economical mppt charge controller. I have the 20 amp model. So far it’s working well. Easy to set the parameters and the manual is very well done and very informative. They really did a nice job on the manual. The only con for me is the displays a little small for my senior citizen eyes but I just use my reading glasses. Once I get some more panels I may purchase a bigger one. The tech support was very responsive and I got a reply almost immediately for the one question I had. Thanks again

A total turd. Display is hard to read and is not intuitive. Also inaccurate; for example, solar inputting 11 amps but controller says zero. Cheap plastic build. I have seen better at half the cost.
