Product description

The Victron SmartSolar MPPT 75/15 is a compact and highly efficient solar charge controller designed for 12V and 24V campervan, boat, and off-grid systems. Using advanced MPPT (Maximum Power Point Tracking) technology, it ensures that every bit of energy from your solar panels is converted into usable charging power for your batteries.

With built-in Bluetooth, the SmartSolar 75/15 allows full monitoring and configuration directly via the VictronConnect app, making it ideal for DIY van builders who want full control over their energy system.

Maximum Solar Efficiency

The SmartSolar MPPT 75/15 continuously tracks the optimal power point of your solar panels, maximizing energy harvest even in low light or cloudy conditions.

Key benefits:

• Up to 98% conversion efficiency
• Better performance than PWM controllers
• Improved charging in partial shading conditions
• Faster battery charging times

Built-in Bluetooth Monitoring

No external dongles needed. The integrated Bluetooth module allows you to:

• Monitor solar yield in real time
• Check battery voltage and charging status
• Adjust charge settings (AGM, Gel, Lithium, etc.)
• View historical performance data
• Update firmware via VictronConnect app

Perfect for campervan installations where easy system access is important.

Smart Battery Charging

The controller uses a fully adaptive 3-stage charging algorithm:

• Bulk
• Absorption
• Float

This ensures safe and efficient charging for multiple battery types:

• Lithium (LiFePO₄)
• AGM
• Gel
• Lead-acid (flooded)

Ideal for Campervan & Off-Grid Systems

The compact design makes it perfect for tight installation spaces in:

• Campervans and motorhomes
• Marine systems
• Off-grid cabins
• Auxiliary battery systems
• Small solar setups

Despite its size, it delivers strong performance and reliability.

Intelligent Load & Battery Protection

The built-in load output helps protect your battery from deep discharge by disconnecting loads when voltage drops too low. This improves battery lifespan and system safety.
