Review on Efficient Victron Energy SmartSolar MPPT 100V 20 Amp 12/24/48-Volt Solar Charge Controller with Bluetooth Connectivity by Victor Shepherd

with charge controllers for over 30 years and they've certainly come a long way. I'm old school and wouldn't have ordered this if I knew I had to download an app to adjust the settings, but I LOVE it! No more switches for me! The app was easy for me too and all the settings are clear, easy to understand and easy to change. In addition, you get a large amount of information about what your system is doing. This is such a well thought out product that I am very impressed. I connected this 100-20 charge controller to two 24v 200w panels charging a lithium battery that controls a water pump.
