The Renogy DC to DC MPPT Onboard Battery Charger is built to provide flexibility. This multi-stage charger with dual input options can charge a service battery from a starter battery linked to an alternator or by utilizing solar panels directly connected to the unit. While the vehicle's alternator prioritizes charging the starter battery, this charger ensures that the solar system charges the service battery first. This intelligent design helps keep your system fully charged, allowing for longer off-grid adventures.

With multi-stage charging and multi-chemistry functionality, Renogy's DC to DC MPPT Charger supports flooded, gel, AGM, and lithium batteries.

The RJ45 communication port allows you to unlock exclusive monitoring features using the BT-2 Bluetooth Module and Renogy DC Home App, enabling real-time remote control and monitoring through your smartphone.
