The Victron SmartSolar MPPT RS 450/200-MC4 is a high-voltage solar charge controller built for large off-grid, hybrid and commercial battery systems. It handles a 450V maximum PV open-circuit voltage and delivers up to 200A of charge current, with MC4 connectors built into the input to simplify wiring on bigger arrays.

Key features of the Victron SmartSolar MPPT RS 450/200-MC4

• PV input, 450V maximum open-circuit voltage, allowing longer strings and fewer parallel runs.
• Charge current, up to 200A for larger battery banks.
• PV connectors, integrated MC4, no separate combiner wiring needed.
• Monitoring, built-in Bluetooth for VictronConnect app commissioning and firmware updates.
• Network, VE.Can compatible, connects to Victron GX devices and Cerbo GX for system-wide monitoring.
• Battery support, 48V systems with automatic battery voltage detection, and configurable profiles for lithium (LiFePO4), AGM, gel and flooded batteries.

Applications

Suited to large off-grid systems with high-capacity battery banks, commercial and industrial solar installations where higher string voltages cut down on cabling, and hybrid setups paired with a Victron Quattro or MultiPlus inverter-charger over VE.Can. It also fits ground-mount or large rooftop arrays where MC4 direct connection keeps the DC wiring simple, and remote sites monitored through VRM via a Victron GX device.

Installation notes

This unit operates at up to 450V DC on the PV input, a hazardous voltage that calls for installation by a qualified electrician or MCS-accredited solar installer. DC wiring, fusing and isolation must meet BS 7671 and the relevant solar PV wiring regulations, and battery connections need to be rated for the 200A charge current. Check battery chemistry and voltage settings in VictronConnect before commissioning. On grid-tied systems, confirm the design meets G98 or G99 requirements as applicable.
