MPPT solar controller Victron Energy SmartSolar 75/10

The SmartSolar solar controller processes the energy from the solar panels and stores it in the batteries, maximizing solar gains, intelligently maintaining the battery condition and extending its lifespan. The SmartSolar solar controller can recharge even a deeply discharged battery, as it can operate with a battery voltage of up to 0 volts, provided that the cells are not permanently sulfated or otherwise damaged.

Ultra-fast MPPT technology:
The controller constantly monitors the voltage and current from the solar panels and, thanks to MPPT technology, extracts the maximum energy from them, which is especially advantageous when the intensity of sunlight varies. MPPT technology ensures up to 30% higher energy gain compared to PWM solar controllers and up to 10% higher gain compared to slower MPPT controllers.

Remote monitoring and control:
If your installation is connected to the Internet using a GX device, the VRM portal provides access to your devices anytime, anywhere.

Load output:
The intelligent Load output function prevents the batteries from discharging below threshold values. You can configure the voltage at which SmartSolar disconnects the load, preventing excessive battery discharge. The BatteryLife function keeps the battery in good condition and extends its life.

Built-in Bluetooth:
With built-in Bluetooth, you can pair the SmartSolar solar controller with your smartphone or other device via the VictronConnect app to set up, monitor or update the system.

VE.Direct connector:
The VE.Direct is used to connect to a GX device, PC or other devices.
