Advanced High-Voltage Solar Control for 48V Systems

Optimise your large-scale off-grid or grid-connected solar power system with the highly capable Victron SmartSolar MPPT RS 450/200-MC4. Engineered for 48V battery banks, this advanced charge controller handles up to 450VDC PV input and delivers an impressive 200A charge current. By supporting longer strings of solar panels, it allows you to significantly reduce the size and cost of your solar cabling while maximising overall system efficiency.

Four Independent MPPT Trackers

One of the most significant challenges in large solar installations is managing shading and varied panel orientations. This controller features four separate Maximum Power Point Trackers (MPPTs), allowing you to connect four distinct solar arrays. Each tracker operates independently to find the optimal power point, ensuring that a shaded or differently angled array does not drag down the performance of the rest of your system. This ultra-fast tracking technology adapts rapidly to changing light conditions, capturing every possible watt of energy.

Streamlined MC4 Connections

Installation is simplified with standard Staubli MC4 connectors on the PV inputs. These secure, weather-resistant connections ensure a reliable link between your high-voltage solar strings and the controller, minimising installation time and reducing the risk of poor contact.

Robust Safety and Galvanic Isolation

When working with high DC voltages, safety is paramount. The SmartSolar MPPT RS incorporates full galvanic isolation between the PV input and the battery connections. Additionally, it continuously monitors the PV isolation resistance. If it detects a fault or drop in resistance, the unit will safely cease operation and trigger an alert, protecting both your equipment and the operators. The heavy-duty steel enclosure and IP21 protection rating further ensure durability in demanding environments.

Intelligent Monitoring and Connectivity

Stay in complete control of your energy system with built-in Bluetooth connectivity. Using the VictronConnect app on your smartphone, you can easily configure settings, view live data, and monitor historical performance. For comprehensive system integration, the inclusion of VE.Can and VE.Direct ports allows seamless communication with Victron GX devices, enabling remote monitoring and data logging via the VRM portal.
