Victron BlueSolar MPPT Solar Charge Controller

The Victron BlueSolar MPPT charge controller efficiently collects solar energy and stores it in your batteries using advanced high-speed technology. It maximizes energy harvest to achieve a full charge faster, while helping to extend battery lifespan through intelligent charging.

Key Features

✔ Ultra-Fast MPPT Technology

• Tracks the Maximum Power Point with exceptional speed, especially useful under changing light conditions (e.g. cloudy skies).
• Increases energy harvest by:
  • Up to 30% more than PWM controllers
  • Up to 10% more than slower MPPT models

✔ Load Output for Battery Protection

• Prevents over-discharge by disconnecting loads at a pre-set battery voltage
• Compatible with Battery Life mode for smarter load management
• Load output is short-circuit proof
• For large loads (like inverters), connect directly to the battery and control the inverter via the load output (interface cable may be required — see manual)

✔ Battery Life Algorithm

• Prevents premature battery aging by avoiding continuous partial charge cycles
• Dynamically adjusts load disconnect thresholds to allow regular full recharges
• Helps maintain lead-acid battery health by ensuring deep cycles only occur when full recharge is possible

Benefits at a Glance

• Faster, smarter charging — ideal for off-grid, marine, and RV solar setups
• Protects your battery investment with intelligent management
• Optimized for solar harvesting even in variable weather
