Review on 🌞 Newpowa 10A MPPT Solar Charge Controller for 12V Battery with LCD Display, Dual USB Ports, Negative Ground - Ideal for Gel AGM and Liquid Batteries, Off Grid Solar Panel Charger - Up to 130W by Donald Cox

This seems to do exactly what it's supposed to do. It charges my AGM for setting parameters and is easy to install for a newbie. What I don't like is the technical support. Email and chat communication left a lot to be desired when looking for a Bluetooth control monitor that would work with this one. The Newpowa website store lists a monitor that does not work with this controller. Eventually after considerable effort I got a plain white monitor that plugs into the port and without the help of the support team I was able to find an application that works with it. Good luck managing with your phone (Android only). Edit: This controller should be a renamed Lumiax controller. The app only works for Android so I had to buy a cheap phone to install it. The name of the application is Solarlife.
