High-Voltage MPPT Charging for Advanced 48V Battery Systems

The Victron SmartSolar MPPT RS is a professional-grade solar charge controller designed for large off-grid and grid-connected systems using high-voltage, series-connected PV arrays and 48V battery banks. Available in 5.76kW (100A)and 11.52kW (200A) models, this controller combines advanced MPPT technology, full connectivity, and high current output in a rugged and modernized package.

Ideal for solar systems requiring performance, scalability, and remote management, the SmartSolar RS offers wide MPPT voltage input, independent PV tracking inputs, active cooling, and complete battery charging customization. A new metal case and fully shrouded terminals enhance both safety and aesthetics in line with Victron’s latest hardware suite.

Key Features:
