The Victron SmartSolar MPPT RS 450/100 is a high-voltage, isolated solar charge controller engineered for serious off-grid power systems in caravans, motorhomes, and RVs. With a maximum PV input voltage of 450V and a 100A maximum charge current, this unit can harvest energy from large solar arrays and efficiently charge a 48V battery bank — delivering up to 5,200W of charging power from a single controller. Its galvanic isolation between the solar (PV) input and the battery output is a standout safety feature, protecting your battery bank and connected equipment from PV array faults. Ultra-fast Maximum Power Point Tracking (MPPT) continuously scans and locks onto the optimal operating point, even under rapidly changing conditions such as partial cloud cover common across Australia's varied climate zones.

Built for demanding Australian conditions — from the scorching Outback to the humid tropics and the remote coastal runs along the Nullarbor — the SmartSolar MPPT RS 450/100 is the go-to choice for full-time caravanners, overlanders, and 4WD adventurers who run high-capacity lithium or lead-acid battery banks and need maximum daily solar harvest without compromise. It integrates seamlessly with the VictronConnect app over Bluetooth for real-time monitoring, configuration, and remote diagnostics from your phone, and connects into the broader Victron ecosystem via VE.Direct and CAN bus — making it ideal for sophisticated Energy Storage System (ESS) setups in premium RVs and off-road builds. Multiple units can also be configured for synchronised parallel operation to scale charging capacity even further.
