Common Questions What is MPPT technology and why is it important? MPPT (Maximum Power Point Tracking) technology continuously monitors the voltage and current output of your solar panels to find the optimal power point, extracting the maximum available power. This is especially beneficial in changing weather conditions, leading to up to 30% more energy harvest compared to older PWM controllers. Can I monitor this controller remotely? Yes, the Victron BlueSolar MPPT 75/15 features a VE.Direct communication port. By connecting an optional VE.Direct Bluetooth Dongle or VE.Direct USB cable (sold separately), you can monitor and configure your system using the free VictronConnect App on your smartphone, tablet, or computer. What battery types are compatible? This controller is compatible with a wide range of battery types, including AGM, Gel, Tubular plate, and Lithium batteries. For Lithium batteries, specific charging parameters can be set via the VictronConnect App to ensure proper charging and protection. What is the IP rating of this controller? The electronic components of the Victron BlueSolar MPPT 75/15 have an IP43 rating, offering protection against solid objects larger than 1mm and water spray. The connection area has an IP22 rating. This makes it suitable for installation in environments where some exposure to dust or splashes is expected. Installation Notes Mount the controller vertically on a non-flammable surface in a well-ventilated area. Ensure correct polarity for all connections (solar, battery, load) to prevent damage. Use appropriate cable gauges for your solar array, battery bank, and loads 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 you are unsure about any aspect of the setup. Before You Buy Verify your solar panel array's open-circuit voltage (Voc) does not exceed 75V. Confirm your total solar panel power (Wp) is within the controller's limits (220W for 12V, 440W for 24V). Check your battery bank's nominal voltage (12V or 24V) for compatibility. Consider purchasing a VE.Direct Bluetooth Dongle or USB cable for full monitoring and customisation features. Ensure you have adequate space for mounting and proper ventilation around the controller. Specifications are subject to change by the manufacturer. Always verify compatibility and requirements with your specific system components. Victron Energy offers a 5-year standard warranty on this power product.
