Description
The SmartSolar MPPT RS 450/100 is Victron's solution for systems with large series-connected PV arrays charging a 48 V battery bank, in both off-grid and on-grid applications where maximum charging power is required. It accepts up to 450 V DC of PV input across a wide 65 to 450 V MPPT operating range, with two independent MPPT trackers so the array can be split and optimised for the site and shading.
Full galvanic isolation between the PV and battery connections adds system safety, and the unit continuously monitors PV array isolation resistance, flagging a fault if it drops to unsafe levels. High-frequency design keeps the 100 A model light at 7.9 kg while delivering up to 5.8 kW of charge power and quiet, efficient operation. Charging is fully programmable for lead-acid, lithium and other chemistries, and a battery temperature sensor is included.
A front-panel display reads battery and tracker data, while built-in Bluetooth, VE.Direct and VE.Can ports allow set-up and monitoring with VictronConnect and a GX device. Up to 25 units can be connected in parallel over VE.Can, with remote monitoring through the VRM portal.

What battery system does the SmartSolar MPPT RS charge?
It is a 48 V charge controller designed for systems with large series-connected PV arrays charging 48 V battery banks, in both off-grid and on-grid applications.
What PV voltage and how many trackers does it have?
It accepts up to 450 V DC PV input with a 65 to 450 V MPPT operating range and a 120 V start-up voltage. The 450/100 has two independent MPPT trackers and the 450/200 has four, each handling up to 4000 W.
Why are the PV connections isolated?
The MPPT RS provides full galvanic isolation between the PV and battery connections for additional system safety, and it continuously monitors the PV array isolation resistance, reporting a fault if it falls below 100 kOhm.
How do I monitor and connect additional units?
Built-in Bluetooth, VE.Direct and VE.Can ports allow configuration and monitoring with VictronConnect and a GX device. Up to 25 units can be connected in parallel over VE.Can to synchronise their charging, with remote monitoring available through the VRM portal.
Which battery types are supported?
The charge settings are fully programmable for different battery chemistries, including lead-acid and lithium, and a battery temperature sensor is included.
