Review on Vehpro Solar Panel Charge Controller MPPT 40A-100A 12V/24V Auto Tracking with Dual USB Ports (100A) by James Hardy

I have a box of my last 4 charge controllers, I added a 5th the day this one came out. All five are PWM charge controllers, and they barely do their job. I have a 55w solar array powering two 35ah 12v deep cycle batteries from about 10 years ago that started out as experimental and worked so well I never took it off. Previously, the batteries ran out in two weeks in cloudy weather. Now they are constantly replenished even during longer cloudy periods. It seems that no matter how often I use the dozen or so 12V LEDs I have, the battery voltage never drops below 12.6V now. This thing collects every electron it can get from my old setup and works better than anything that came before it. My partner is sensitive to LEDs that flicker almost visibly. With all PWM controllers, this was a constant problem that got worse with dimming. These problems are gone with this MPPT controller! That alone makes it double the price I paid, and the fact that it collects more power than any of its competitors (which I've personally used) makes it even better. Try it!
