Overview
The MPPT RS SmartSolar is a 48V Solar charge controller with up to 450VDC PV input and either 100A or 200A 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 for the 100A model. 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 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. VE.Can and VE.Direct port. For connection to a GX device for system monitoring, data logging, and remote firmware updates. VE.Can allows for up to 25 units to be connected together in parallel and synchronise their charging. 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.

How to read this datasheet
Victron SmartSolar MPPT RS is listed with 14 published specifications from Victron Energy, including system battery voltage of 48V, max VOC of 450V*, max current (DC) of 100A and MPPT trackers of 2. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.
For a charge controller, the figures that matter most are whether it offers a load output, temperature compensation and remote monitoring, type: MPPT or PWM, rated charge current in amps, which must exceed the array's short-circuit current with margin and maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise. In any system with a battery and a separate array, the controller is what protects the most expensive component and determines how much of the array's output actually reaches storage.
What to check before ordering
The checks below apply to any charge controller. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.
- Size the current rating from array watts divided by battery voltage, then add at least 25% margin for cold, bright conditions where panels exceed their rated output.
- Check the maximum PV input voltage against the array's Voc at your coldest expected temperature, not at 25 °C — Voc rises as temperature falls, and exceeding the limit destroys the controller instantly.
- Confirm the controller supports your battery chemistry with the right charge profile. Lithium, AGM, gel and flooded batteries need different absorption and float voltages.
- Prefer a unit with temperature compensation or a battery temperature sensor if the bank lives somewhere that gets hot or cold.
Where buyers lose money
- Sizing on rated array watts alone and ignoring the voltage ceiling, which is the most common way controllers are killed.
- Using a PWM controller with a high-voltage grid-tie panel — the voltage mismatch wastes a large share of the panel's output.
- Running the load output beyond its rating instead of wiring heavy loads directly to the battery through a fuse.
Price and availability
Victron SmartSolar MPPT RS is listed at £ 920 (GBP). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.
SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Victron Energy locally before ordering.
Victron SmartSolar MPPT RS — frequently asked questions
How much does Victron SmartSolar MPPT RS cost?
Victron SmartSolar MPPT RS is listed at £ 920 (GBP). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.
What are the specifications of Victron SmartSolar MPPT RS?
We hold 14 published specifications for this charge controller, including system battery voltage 48V, max VOC 450V*, max current (DC) 100A, MPPT trackers 2 and connectivity Bluetooth, VE.Direct, VE.Can. The full table is on this page, listed under model VSS-MPPTRS450/100-MC4.
Who makes Victron SmartSolar MPPT RS?
Victron SmartSolar MPPT RS is a Victron Energy product, listed under charge controllers with model reference VSS-MPPTRS450/100-MC4. The Victron Energy brand page lists the rest of its range so you can compare across the catalogue.
Is Victron SmartSolar MPPT RS right for my system?
That depends on what it has to connect to. For a charge controller, check supported battery voltages (12/24/36/48 V) and chemistries, conversion efficiency, typically 96–99% for a good MPPT unit and whether it offers a load output, temperature compensation and remote monitoring against the rest of your equipment before price enters the decision. Check the maximum PV input voltage against the array's Voc at your coldest expected temperature, not at 25 °C — Voc rises as temperature falls, and exceeding the limit destroys the controller instantly.
Where can I buy Victron SmartSolar MPPT RS?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer — buying in-channel is what keeps the manufacturer's warranty valid.
