The SmartSolar MPPT RS solar charge controller is Victrons solution for systems with large series connected PV arrays charging 48 V DC battery banks. This product is perfect for large off-grid, and grid connected battery system.

The 450/100-Tr is suitable for up to 5.76KW 80-450 VDC operating solar voltage input featuring independent tracking inputs, full connectivity, isolated PV connections, display screen, fully programmable battery charging parameters and active cooling. The new metal case design and fully covered electrical connections improve the safety and modernise the presentation in line with the latest suite of Victron products.

Ultra-fast Maximum Power Point Tracking (MPPT) Solar Charge Controller

The MPPT RS SmartSolar is a 48V Solar charge controller with up to 450VDC PV input and 100A output. It is used in on-grid and off-grid solar applications where maximum battery charging power is required.

Multiple independent MPPT tracking inputs

With multiple MPPT trackers, you can optimise your solar panel design for maximum performance for your specific location.

Isolated PV connections for additional safety

Full galvanic isolation between PV and battery connections provide additional overall system safety.

Wide MPPT voltage range

80 – 450 VDC PV operating range, with a 120VDC PV startup voltage

Light weight, efficient and quiet

Thanks to high frequency technology and a new design this powerful charger weighs only 7.9 kg. In addition to this it has an excellent efficiency, low standby power, and a very quiet operation.

Display and Bluetooth

The display reads battery, and solar charge controller parameters. The parameters can be accessed with a smartphone or other Bluetooth enabled device. In addition, Bluetooth can be used to set up the system and to change settings with VictronConnect.

PV Isolation resistance monitoring for peace of mind at higher voltages

The MPPT RS continuously monitors the PV array and can detect if there are faults that reduce the isolation of the panels to unsafe levels.

Daisy Chain Additional Units. VE.Can and VE.Direct port

The SmartSolar RS charge controller is equipped with VE.Can bus ports. This allows for communication with additional SmartSolar RS & VE.Can MPPT units. The additional units are simply “daisy chained” to each other with an RJ45 cable. When connected to each other, all individual charge controllers, will synchronise their charge stages. They can also send their data, via the same cable, for monitoring to a GX device (such as the Cerbo GX) for system monitoring, data logging, and remote firmware updates.

I/O Connections

Programmable Relay, temperature sensor, auxiliary, digital input and voltage sensor connections. The remote input can accept the Victron smallBMS, and other BMS with allow-to-charge signal.
