Victron charge controller MPPT BlueSolar 75/15 - 12V / 24V 15A


  • Ultrafast Tracking Maximum Power Point Tracking (MPPT, for its acronym in English)
  • Electronic components encapsulated in resin to protect electronic components from the elements.
  • BatteryLife: Intelligent battery management

When a solar charge controller is not able to recharge the battery to full capacity in a day, what happens is that the battery cycle continuously changes between states "partial charge" and "discharge end." This mode of operation (no regular full recharge) destroy a lead-acid battery in weeks or months.

BatteryLife The algorithm monitors the state of charge of the battery and increases slightly from day to day, the level of load shedding up to the absorption voltage. From that point, the level of load shedding is modulated so as to reach the absorption voltage aa about once a week.

The MPPT 75/15 can also be configured to keep the load control mode traditional disconnection with a fixed voltage.

The output load is short circuit proof and can provide capacitive loads such as an inverter.

Electronic components encapsulated in resin

  • Protects electronic components from the elements

Automatic recognition of the battery voltage

  • The MPPT 75/15 system automatically adjusts to 12 or 24 V.
