Victron SmartSolar MPPT 100/20 12/24/48V Bluetooth Solar Controller

Overview

The Victron SmartSolar MPPT 100/20 is a premium solar charge controller designed to extract maximum usable power from solar panels and charge your battery system efficiently. It is a strong choice for 4WD touring builds, caravans, camper trailers, marine systems and off-grid auxiliary battery setups where reliable solar charging matters.

Using Victron’s fast MPPT tracking technology, the controller constantly adjusts the solar input to find the most efficient voltage and current combination. This helps improve charging performance compared with basic PWM regulators, especially when sunlight changes throughout the day.

Why It Works Well in 4WD, Caravan and Off-Grid Systems

The built-in Bluetooth connection makes setup and monitoring simple through the VictronConnect app. From your phone, you can check solar output, battery voltage, charge status, history and controller settings without needing a separate display. This makes it easier to diagnose system performance and keep your battery setup healthy while travelling or camping.
