Renogy 40 Amp MPPT Charge Controller
We upgraded all of our solar on the RV, and the Renogy Rover 40 Amp Charge Controller was one of the best upgrades. Installation was super easy, and it has an optional Bluetooth module so you can monitor everything with an iPhone app. We actually had an issue with the first one we installed, but Renogy replaced it and had good support.
