MPPT Solar Charge Controller Victron Energy SmartSolar 75/10

The manufacturer provides a 5-year warranty on Victron Energy products.

The SmartSolar solar charge controller converts energy from solar panels to batteries in a way that maximizes solar power utilization. By intelligently managing charging, it keeps the battery in good condition and helps extend its lifespan. It can even charge a deeply discharged battery – it works even at battery voltages down to 0 V, provided the cells are not irreversibly damaged, for example, by sulfation.

Key features:

Ultra-fast MPPT technology:
The controller continuously monitors the voltage and current from the solar panels and, thanks to MPPT technology, extracts maximum energy from them, which is particularly beneficial with variable solar radiation intensity. MPPT technology provides 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 via a GX device, the VRM portal provides access to your devices anytime, anywhere. 

Load output:
The intelligent Load output function prevents batteries from discharging below critical levels. You can configure the voltage at which the SmartSolar will disconnect the load, thereby preventing excessive battery discharge. The BatteryLife feature keeps the battery in good condition and extends its lifespan. 

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

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