Victron SmartSolar MPPT RS Charge Controller — 450/100 & 450/200

High-Voltage MPPT Charging for Advanced 48V Battery Systems

The Victron SmartSolar MPPT RS is a professional-grade, fully isolated 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, multiple 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.

Who the SmartSolar MPPT RS is built for

• Large off-grid homes and commercial systems — high-voltage series PV arrays into a 48 V bank, where 5.76–11.52 kW of charging is needed.
• Bluewater yachts and superyachts — big arrays and 48 V house banks that have outgrown the conventional MPPT range.
• Expedition vehicles — large rooftop arrays feeding a 48 V system through independent PV trackers.
• Installers and system integrators — VE.Can daisy-chaining, a programmable relay, BMS allow-to-charge input, and VRM remote management.

Key Features:

• Ultra-Fast MPPT Technology
  Maximizes solar energy harvest—even under shading or changing light conditions.

• Wide PV Input Range
  Operates between 65–450V DC (120 V startup), perfect for large series-connected PV arrays.

• Multiple Independent MPPT Trackers
  Two trackers on the 450/100 and four on the 450/200, so separate PV arrays can be tracked independently for greater design flexibility (16 A operational / 20 A short-circuit, 4,000 W per tracker).

• Isolated & safety-monitored
  Full galvanic isolation between PV and battery, plus continuous PV isolation-resistance monitoring that flags unsafe panel faults at high voltage.

• Fully Programmable Charging
  Configure settings for lead-acid, lithium, and other chemistries using VictronConnect. A battery temperature sensor is included.

• Integrated Display
  Real-time readout of battery voltage, charge current, PV input stats, system status, and error codes.

• Bluetooth Smart Built-In
  Wireless configuration and monitoring via the VictronConnect app, with 30 days of per-tracker history on the device.

• VE.Can Bus Communication
  Daisy-chain up to 25 RS units and synchronize charge stages across controllers.

• Remote Monitoring via VRM
  When connected to a GX device and the internet, full remote access via the Victron Remote Management (VRM) portal.

• I/O and Sensor Support
  Includes a programmable relay, inputs for temperature and voltage sensing, two general-purpose analogue/digital inputs, and compatibility with Victron BMS allow-to-charge signals.
