Description
xVictron SmartSolar MPPT RS 450/100-MC4 Solar Charge Controller
The Victron SmartSolar MPPT RS 450/100-MC4 is a high-voltage solar charge controller designed for large-scale off-grid and hybrid battery systems. With a 450V maximum PV input voltage and 100A charge current, it suits commercial installations and large residential systems where high string voltages are required. The integrated MC4 connectors allow direct connection to standard solar panel strings without additional wiring adaptors.
Key Features
- 450V maximum PV open-circuit voltage, allowing long panel strings with fewer parallel runs.
- 100A maximum charge current, suitable for large battery banks in off-grid and hybrid systems.
- Integrated MC4 connectors for direct, tool-free connection to standard solar panel cables.
- Built-in Bluetooth via the VictronConnect app for configuration, monitoring and firmware updates without additional hardware.
- Compatible with the VE.Can network, enabling integration with Victron GX devices, Cerbo GX and system monitoring platforms.
- Wide battery voltage compatibility covering 12V, 24V, 36V and 48V systems, with automatic detection.
- Advanced MPPT algorithm with rapid tracking to maximise energy harvest under variable irradiance conditions.
- Supports lithium, AGM, gel and other battery chemistries with programmable charge profiles.
Product Overview
The RS series sits above the standard SmartSolar MPPT range in terms of input voltage capability. A 450V PV input ceiling means installers can wire more panels in series per string, reducing the number of strings and associated cabling costs. This is particularly relevant on larger rooftop or ground-mount arrays where minimising DC cable runs has a direct impact on system efficiency and installation labour.
The 100A output current is delivered across a wide battery voltage range. At 48V, this equates to approximately 4.8kW of charge power from a single unit. The controller communicates over VE.Can, which means it integrates natively into Victron system architectures alongside MultiPlus or Quattro inverter-chargers, GX monitoring devices and the VRM online portal. Configuration is handled through VictronConnect over Bluetooth, removing the need for a separate programming interface during commissioning.
The MC4 input connectors are factory-fitted, which simplifies installation on systems using standard MC4-terminated panel cables. This avoids the need for field-fitted connectors on the high-voltage DC input side, reducing a potential point of failure and saving installation time on site.

Installation Notes
This controller operates at up to 450V DC on the PV input, which is a high-voltage DC system. Installation must be carried out by a qualified electrician or MCS-accredited solar installer with experience in high-voltage DC systems. The unit should be mounted in a ventilated enclosure or on a suitable surface away from direct weather exposure. VE.Can termination resistors must be correctly fitted when integrating with a Victron CAN bus network. Battery chemistry and charge profile settings must be configured correctly before commissioning to avoid damage to the battery bank.
