Common Questions What is MPPT technology and why is it important? MPPT (Maximum Power Point Tracking) technology ensures your solar panels operate at their peak efficiency by continuously adjusting to the optimal voltage and current. This results in up to 30% more energy harvest compared to older PWM controllers, especially beneficial in variable weather conditions. Can I monitor this controller remotely? Yes, the SmartSolar MPPT 250/100 has built-in Bluetooth. You can use the free VictronConnect App on your smartphone, tablet, or computer to monitor real-time data, view historical logs, and configure settings wirelessly. Is this controller compatible with lithium batteries? Yes, the Victron SmartSolar MPPT 250/100 is compatible with a wide range of battery types, including Lithium, AGM, Gel, and Tubular plate batteries. Its charging algorithm is fully programmable to match specific battery chemistry requirements. What is the purpose of the VE.Can and VE.Direct ports? The VE.Can port allows for daisy-chaining multiple SmartSolar controllers for synchronised charging and integration with Victron GX monitoring devices. The VE.Direct port provides connectivity for single-unit monitoring or other VE.Direct accessories. Installation Notes Ensure adequate ventilation around the controller to prevent overheating, especially under full load. Always connect the battery first, then the solar panels, and disconnect in reverse order. Use appropriately sized cables for PV and battery connections to minimise voltage drop and ensure safety. Refer to the detailed user manual for specific wiring diagrams and installation instructions. Consider professional installation for complex systems or if unsure about electrical wiring. Before You Buy Verify your total solar panel array voltage (Voc) does not exceed the controller's 250V limit. Confirm your battery bank voltage (12V, 24V, 36V, or 48V) matches the controller's auto-detection or manual setting. Calculate your maximum solar panel power to ensure it falls within the controller's specified limits for your battery voltage. Consider any additional Victron accessories, such as a GX device or external display, for enhanced monitoring. Ensure the physical dimensions and mounting requirements are suitable for your intended installation location. Always verify product specifications and compatibility with your existing system components before purchase. This Victron SmartSolar MPPT 250/100 controller is covered by a 5-year manufacturer's warranty.
