The SmartSolar MPPT RS 450V/100A-MC4 is a new-generation smart charge controller from Victron Energy, designed to work with large arrays of solar modules in 48 V systems.
With a maximum PV input voltage of 450 V, a charging current of up to 100 A, and built-in Bluetooth, VE.Can, and VE.Direct, this model combines power, intelligence, and reliability in a single enclosure.
It is ideally suited for projects based on LiFePO4 batteries, ESS systems, off-grid power, and agricultural and industrial installations.
Key Benefits of the SmartSolar MPPT RS Controller
- Incredible charging power – 100 A
- PV input voltage up to 450 V – connection of long strings
- High efficiency – up to 98%
- Designed to work exclusively with 48 V systems
- Integrated display – configuration, diagnostics, monitoring
- Fully compatible with LiFePO4 batteries
- Supports data transmission from BMS from most well-known certified manufacturers (Pylontech, Sacred Sun, Deye, Sunlight, Dyness, Everexeed, and others), and can be configured for custom voltage setups.
- Compatibility with Victron Energy VRM and GX devices
- Fanless passive cooling + active cooling when needed
- Dual PV inputs (with independent MPPT) – efficiency with mixed panel orientation
Technical Features
Dual PV trackers
The controller has two independent MPPT trackers, allowing:
- Connect 2 arrays with different orientations/tilt angles
- Increase efficiency under uneven lighting conditions
- Optimize systems with different installation geometries
Ultra-high PV voltage
Support for up to 450 V DC allows:
- Minimize losses over long distances
- Use a larger number of modules in series
- Simplify installation thanks to fewer cables
Built-in display
Direct access to:
- Operating parameters
- Errors and warnings
- Charging history
- Settings (also available via VictronConnect)
Smart technologies
- Bluetooth for mobile monitoring
- VE.Can – for operation in a network of controllers, integration with Cerbo GX, Venus GX, VRM
- VE.Direct – for connection to BMV, Color Control, and other devices
Integration with LiFePO₄
- Automatic operation with Victron BMS or third-party BMS via VE.Can
- Battery protection: voltage, temperature, and current monitoring
Use cases
- Solar power plants on homes/villas – large numbers of panels in series
- Hybrid systems with backup – with MultiPlus-II, Quattro, ESS
- Industrial applications – high energy consumption, smart automation
- Agricultural sector – off-grid power supply for facilities without grid access
- Marine systems with high battery capacity – on boats/yachts with LiFePO₄
Communication and monitoring interfaces
- VE.Can – for synchronization with other Victron devices, including Cerbo GX
- VE.Direct – for connection to BMV, USB interfaces, or VRM
- Bluetooth – connection to the VictronConnect app
- Digital inputs – connection of sensors, relays
- Relay output – for automation (fans, generator, etc.)
- Display – on-site monitoring
