Renogy Rover Li 40A MPPT Solar Charge Controller with Bluetooth

The Go-To Controller for Van Builds and Overlanding Rigs

The Renogy Rover Li 40A MPPT Charge Controller with Bluetooth is the most popular controller choice for 12V van and RV solar builds. It handles up to 520W of solar input at 12V, communicates directly with LiFePO4 batteries for optimized charging, and lets you monitor everything in real time from the Renogy DC Home app via Bluetooth.

Why MPPT Over PWM

MPPT controllers extract up to 30% more power from your panels than PWM controllers — especially in partial shade or cold weather. For any LiFePO4 battery build, MPPT is the only smart choice.
