Victron BlueSolar MPPT 75/10 - 100/50 Charge Controller

The Victron Blue Solar charge controller features the latest and fastest technology, allowing this solar charge controller to maximize energy harvesting through intelligent control. This ensures a full charge in the shortest possible time. BlueSolar keeps the battery in good condition, thereby extending its lifespan.

Main features of the Victron Blue Solar charge controller

• Ultra-fast Maximum Power Point Tracking (MPPT)
• Advanced Maximum Power Point Detection in the event of varying shade
• Load output on the smaller models
• BatteryLife: intelligent battery management by reducing load
• Automatic detection of the battery voltage
• Flexible charging algorithm
• Over-temperature protection and power derating at high temperatures


Ultra-fast Maximum Power Point Tracking (MPPT)
Especially when it is cloudy and the light intensity is constantly changing, an ultra-fast MPPT controller improves the energy yield by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

Load output
A discharge that is too deep can be prevented by connecting all loads to the load output. The load output disconnects the load if the battery is discharged to a preset voltage.
Alternatively, an intelligent battery management algorithm can also be chosen: see BatteryLife.
The load output is short-circuit protected.
Some loads (especially inverters) are best connected directly to the battery, with the inverter's remote control connected to the load output. You may need a special interface cable. See the manual for details.

BatteryLife: intelligent battery management
If a solar charge controller cannot fully recharge the battery in a single day, the result is often that the battery constantly fluctuates between 'partially charged' and 'fully discharged'. Due to this condition (no regular full charge), a lead-acid battery becomes irreparably damaged within a few weeks or months.
The BatteryLife algorithm monitors the battery's state of charge and, if necessary, increases the load disconnection level slightly from day to day (by disconnecting the load earlier) until the harvested solar energy is sufficient to charge the battery to almost a full 100%. From that moment on, the load disconnection level is modulated so that the battery is charged to almost a full 100% approximately once a week.
