Built-In Protection Functions The Victron BlueSolar MPPT 75/10 is equipped with comprehensive electronic protection features to ensure safe and reliable operation. These include safeguards against battery reverse polarity • PV reverse polarity • output short circuit • over-temperature protection with power de-rating • and battery overcharging. The unit also features an internal temperature sensor for optimal charging and self-diagnostic capabilities with LED fault indicators. Common Questions What is the maximum solar panel wattage I can connect? For a 12V battery system, you can connect up to 145W of solar panels. For a 24V battery system, the maximum is 290W. The controller will limit input power if more PV power is connected. Do I need additional accessories for monitoring? For advanced monitoring and programming via the VictronConnect App, you will need an optional VE.Direct Bluetooth Smart dongle or a VE.Direct USB cable, both sold separately. An optional MPPT Control Panel is also available for direct display. Is this controller suitable for Lithium batteries? Yes, the Victron BlueSolar MPPT 75/10 is compatible with Lithium batteries. However, specific Lithium battery settings may require adjustment via the VictronConnect App, which necessitates a separate Bluetooth dongle or USB interface. What is the 'BatteryLife' feature? BatteryLife is an intelligent battery management algorithm that prevents over-discharge. If the battery cannot be fully recharged daily, it gradually raises the load disconnect voltage until a near 100% recharge is achieved, typically once a week, to prolong battery health. Installation Notes Mount the controller in a cool, dry, and well-ventilated area, away from direct sunlight. Ensure correct polarity for all connections (solar panel, battery, load) to prevent damage. Use appropriate cable gauges for your system's current and distance to minimise voltage drop. Refer to the manufacturer's manual for detailed wiring diagrams and safety instructions. Consider professional installation for complex systems or if unsure about electrical work. Before You Buy Verify your solar panel's open circuit voltage (Voc) does not exceed 75V. Confirm your total solar panel wattage is within the controller's limits (145W for 12V, 290W for 24V). Check your battery bank's nominal voltage (12V or 24V) for compatibility. Consider if you require remote monitoring and purchase the necessary VE.Direct accessories separately. Ensure the physical dimensions (100 x 113 x 40 mm) fit your intended mounting location. Always verify product specifications and compatibility with your existing system components before purchase. Consult the official Victron Energy documentation for complete details and safety guidelines.
