The Victron SmartSolar MPPT RS 450/200 is compatible with all common 48V battery chemistries, including Lithium (LiFePO4), AGM, Gel, and Tubular Plate batteries. Its charging algorithm is fully programmable to match specific battery manufacturer requirements. How does the 4-MPPT design benefit my solar array? The four independent MPPT inputs allow you to connect separate strings of solar panels, each operating at its optimal power point. This maximises energy harvest, especially when panels are installed at different orientations, tilt angles, or experience varying levels of shading. Can I monitor this controller remotely? Yes, the controller has built-in Bluetooth for wireless connection to the VictronConnect App on your smartphone or tablet. It also features VE.Direct and VE.Can ports for wired communication with Victron GX devices and the Victron Remote Management (VRM) portal for advanced remote monitoring and control. What is the maximum solar array size I can connect? Each of the four MPPT trackers can handle up to 7200 Wp (Watt-peak) of solar input, with a maximum operational PV input current of 16A per tracker. The total maximum DC output charging power for the unit is 11520W. Installation Notes Installation should be carried out by a qualified professional to ensure safety and compliance with local electrical regulations. Ensure adequate ventilation around the unit, as it features active cooling. Always follow the wiring instructions provided in the official Victron Energy manual for correct and safe connection of PV arrays and batteries. Verify PV array voltage and current are within the controller's specified limits before connection. Proper grounding of the system is essential for safety and optimal performance. Before You Buy Confirm your battery bank voltage is 48V to ensure compatibility with this controller.
