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

📝 Victron SmartSolar MPPT 100/20 (Up to 48V)

The Victron SmartSolar MPPT 100/20 is a high-efficiency solar charge controller that delivers intelligent energy harvesting for off-grid, RV, and marine systems. Designed for 12V, 24V, 36V, and 48V battery banks, it uses ultra-fast Maximum Power Point Tracking (MPPT) technology to optimise solar performance — even in cloudy or variable light conditions. With Bluetooth Smart built-in, users can configure, monitor, and update their controller effortlessly via the VictronConnect app.

⭐ ESSENTIAL BENEFITS

• Ultra-fast MPPT tracking – boosts solar charging efficiency by up to 30% compared to PWM and 10% compared to slower MPPT units.
• Dynamic solar optimisation – continuously adjusts for changing sunlight intensity to extract the maximum power from your panels.
• Bluetooth Smart connectivity – allows for wireless monitoring, setup, and firmware updates directly from your smartphone or tablet.
• Victron Remote Management (VRM) – provides remote system control and analytics anywhere in the world when paired with a GX device.
• Battery Life algorithm – intelligently manages charge cycles to maintain battery health, ensuring consistent full recharges and extending lifespan.
• Load output management – protects against over-discharge by automatically disconnecting loads when voltage drops too low.
• Zero-volt recovery – reactivates charging from fully depleted batteries, including lithium systems with integrated BMS disconnect.
• Proven Victron reliability – rugged, efficient design suitable for long-term off-grid use.

⚙️ HOW IT WORKS / FUNCTIONALITY

The SmartSolar MPPT 100/20 continuously tracks the maximum power point of connected solar panels, optimising charge performance under changing light or shading. Its intelligent Battery Life algorithm regulates the discharge threshold daily to ensure consistent full charge cycles. Through Bluetooth or VE.Direct, users can access live system data, adjust charging profiles, and control loads safely and efficiently.
