I bought a Rich Solar 40A MPPT controller for my van. The 40A is way over spec as I only have a 100W panel but it may move to a boat with more panels, so that's why.
Did a bench setup, build a serial cable and got the software to work. After some tinkering I was able to set the controller to accept 60Ah for my LiFePo4 battery. Did some more testing and I found that the battery temp sensor seems to work only for compensation for lead acid cells. Even so I got the probe plenty cold at -15C or 5F the controller happily kept on supplying a charge current to my battery. No harm done, the sensor was in a cold solution, battery at room temp but the desired protection does not seem to be part of the setup. Controller model ML2440N10 version V0.0.3
My mistake or lack of features?
