Review on Enhanced Performance: RICH SOLAR 20 Amp MPPT 🌞 Solar Charge Controller with LCD Display for Various Battery Types by Todd Nordine

This replaced one of those $15 PWM controllers that could only produce 50W in full sunlight from my single 100W PV panel. I thought the PV was faulty but found that this controller outputs up to 120W while accurately tracking the MPP point. It's very well built with robust terminals and displays lots of good data on the LCD (although the status LEDs are too dim). I also like how the 12V load output can be controlled; manually, by time or by photovoltaic voltage. External monitoring software can be downloaded from the R****y Rover website and they have a better manual too.
