Common Questions What is MPPT technology and why is it important? MPPT (Maximum Power Point Tracking) technology continuously optimises the voltage and current output from your solar panels to maximise energy harvest. This is particularly beneficial in conditions where light intensity changes frequently, such as on cloudy days, improving energy yield by up to 30% compared to older PWM controllers. How do I monitor and configure the SmartSolar 250/85? The controller features built-in Bluetooth Smart, allowing wireless monitoring and configuration via the free VictronConnect App on your smartphone or tablet. Additionally, VE.Direct and VE.Can communication ports enable wired connections to other Victron devices, such as GX monitoring systems, or a PC. Is this charge controller compatible with Lithium batteries? Yes, the Victron SmartSolar MPPT 250/85 is compatible with a wide range of battery types, including AGM, Gel, Tubular plate, and Lithium. Its flexible and fully programmable charge algorithm allows for precise customisation to suit specific battery chemistries. Can multiple SmartSolar controllers be used together? Yes, the VE.Can communication port allows for the synchronisation of multiple SmartSolar controllers for parallel charging, enabling scalable system designs. Up to 25 units can be synchronised via VE.Can, and up to 10 units via Bluetooth. Installation Notes Professional installation by a qualified electrician is highly recommended to ensure safety, compliance with local regulations, and optimal system performance. Ensure correct wiring gauge and appropriate fusing are used for both the PV array and battery connections, adhering to manufacturer guidelines. Mount the controller in a well-ventilated area, protected from direct sunlight, moisture, and excessive heat, to maintain optimal operating temperature and longevity. Always consult the official Victron Energy product manual for detailed installation instructions, wiring diagrams, and safety guidelines specific to this model. Before You Buy Verify your total solar panel array's open-circuit voltage (Voc) and maximum power output (Pmax) to ensure it remains within the controller's 250V and specified wattage limits for your chosen battery voltage. Confirm your battery bank's nominal voltage (12V, 24V, 36V, or 48V) and chemistry to ensure compatibility and to correctly set the charging parameters. Consider any future expansion plans for your solar array or battery bank to ensure the controller can accommodate increased capacity without exceeding its limits. Ensure you have the necessary cables, connectors, and any optional accessories (e.g., external display) required for your specific installation. All specifications are based on manufacturer data and are subject to change. Always refer to the official Victron Energy documentation for the most current information. This product is covered by a 5-year warranty.
