Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) – 100V, 20A, 48V

Overview

The Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) is designed to turn abundant sunlight into reliable energy for your battery bank. Built with a sleek, durable chassis and smart software, it optimizes charging in real time so energy from your panels goes further while supporting battery longevity.

Smart charging that adapts to your sun

At the heart of this controller is a fast MPPT tracker and intelligent charge algorithms. As light levels shift during the day, the unit quickly recalculates the maximum power point, converting more sunlight into usable energy—even when panels are partially shaded or experiencing sun-angle changes.

• Rapid MPPT tracking for higher energy harvest
• Smart algorithms that adapt to changing conditions
• Built to protect battery health over long-term use

Shade-tolerant performance

Partial shading or cloudy spells don’t derail charging. The controller maintains efficient operation and prevents unnecessary energy loss, helping you keep the battery at a usable level when conditions aren’t perfect.

• Maintains charging efficiency in variable light
• Supports more consistent energy delivery across the day

Synchronization for multi-controller setups

If you deploy several SmartSolar units, they can synchronize to behave as one system. This coordinated charging helps extend battery life and optimize energy use across the entire array, especially in larger installations.

• System-wide optimization with multiple controllers
• Coordinated charge stages for longevity

Connectivity and configuration

The VictronConnect app opens a window into your solar setup. Monitor real-time data, review up to 30 days of performance history, and tailor the system with battery presets. Firmware updates and alarms keep the system aligned with your needs.

• Real-time insights and historical data
• Battery presets, firmware updates, and alarms

Intelligent load output

Power devices directly from the charger with an integrated load output. You can set the voltage at which a load should disconnect, and the controller will automatically drop power if the battery drops too low, protecting your energy storage.

• Direct device power with built-in load control
• Low-voltage disconnect to safeguard batteries

Real-world uses

Ideal for off-grid cabins, RVs, boats, or distributed solar arrays. The compact unit fits into small enclosures, while Bluetooth connectivity makes setup and monitoring convenient from your device. It’s a flexible solution for growing solar systems.
