Description
x📝 Victron SmartSolar MPPT 75/15 Bluetooth 12V/24V
The Victron SmartSolar MPPT 75/15 is a powerful and intelligent solar charge controller designed to maximise solar energy yield for off-grid, caravan, marine, and RV systems. Using ultra-fast Maximum Power Point Tracking (MPPT) technology, it ensures optimal performance even in partially shaded or low-light conditions. With built-in Bluetooth Smart, the 75/15 allows you to monitor, configure, and optimise your solar setup directly from your phone using the VictronConnect app.
<>⭐ ESSENTIAL BENEFITS
• Ultra-fast MPPT technology – increases solar energy harvest by up to 30% over PWM and up to 10% over slower MPPT controllers.
• Bluetooth Smart built-in – enables real-time configuration, monitoring, and firmware updates via VictronConnect.
• Remote monitoring and control – integrate with Victron VRM Portal for global system access through a GX device.
• Battery Life algorithm – intelligently manages charge cycles to extend battery life by preventing over-discharge and ensuring full recharge cycles.
• Load output management – disconnects loads when voltage drops too low to protect your battery from deep discharge.
• Zero-volt recovery – automatically restarts charging even from fully discharged batteries, including Li-ion systems with disconnect protection.
• Intelligent protection – safeguards against short-circuit, reverse polarity, and over-temperature conditions.
⚙️ HOW IT WORKS / FUNCTIONALITY
The SmartSolar MPPT 75/15 constantly monitors PV panel output to track the Maximum Power Point, ensuring maximum efficiency under changing sunlight conditions. The integrated Battery Life management system adjusts load cut-off levels dynamically, encouraging full recharge cycles to maintain optimal battery health. Control and data access are available via Bluetooth or VE.Direct, giving you complete visibility of your system’s performance.
<>🔌 COMPATIBILITY
• Suitable for 12v and 24v battery systems (auto-select).
• Compatible with AGM, GEL, Lead-acid, and LiFePO4 batteries.
