Victron Energy BlueSolar MPPT 75/15

The Victron BlueSolar MPPT 75/15 Solar Charge Controller is a high-performance solar charger designed to maximise energy harvest from your solar panels while protecting and extending the life of your batteries. Using ultra-fast MPPT (Maximum Power Point Tracking) technology, it intelligently converts available solar power into the fastest possible charge—even in changing or partially shaded conditions.

Ideal for off-grid solar systems, RVs, caravans, boats, backup power setups, and small residential installations, the BlueSolar MPPT 75/15 delivers industry-leading efficiency, reliability, and smart battery management.

Ultra-Fast MPPT Technology

By continuously tracking panel voltage and current, the BlueSolar MPPT ensures that every usable watt of solar energy is captured. This advantage is especially noticeable during cloudy weather or fluctuating sunlight, where MPPT technology significantly outperforms traditional PWM controllers.

• Up to 98% peak efficiency

• Faster charging compared to PWM controllers

• Optimised performance in low-light conditions

Intelligent Battery Protection with BatteryLife™

The built-in BatteryLife algorithm actively prevents deep battery discharge. If poor weather prevents a full daily recharge, the controller automatically adjusts the load disconnect voltage to protect battery health. This intelligent management dramatically extends battery lifespan and improves long-term system reliability.

Remote Monitoring & Smart Control

Monitor and configure your system effortlessly:

• VE.Direct port for data communication

• Compatible with VictronConnect (via Bluetooth dongle)

• Remote access via Victron VRM Portal when paired with a GX device

• Optional GlobalLink 520 support for remote, off-grid monitoring

Track real-time data, historical performance, and fine-tune charging parameters—all from your smartphone or computer.

Built-In Load Output for DC Applications

The intelligent load output allows you to power DC devices directly while protecting batteries from over-discharge. Fully programmable disconnect and reconnect voltages ensure safe, efficient power delivery for lighting, control systems, and other DC loads.
