Common Questions What is the main benefit of MPPT technology? MPPT (Maximum Power Point Tracking) technology continuously monitors the voltage and current output of your solar panels to find the optimal power point. This ensures that the maximum available power is harvested, especially in conditions where light intensity is constantly changing, such as partially clouded skies, improving energy yield by up to 30% compared to traditional PWM controllers. How can I monitor my SmartSolar MPPT 150/35? The SmartSolar MPPT 150/35 features built-in Bluetooth Smart, allowing you to monitor and configure it wirelessly via the free VictronConnect app on your smartphone or tablet. For internet-connected installations with a Victron GX device, the Victron Remote Management (VRM) Portal provides remote access from anywhere. What battery types are compatible with this controller? The SmartSolar MPPT 150/35 automatically supports 12V, 24V, and 48V battery systems. It can also be configured for 36V systems using a software tool. Its flexible charge algorithm allows for customisation to suit various battery chemistries, including AGM, GEL, Flooded, and Lithium (LiFePO4 with internal BMS). What is the BatteryLife feature? BatteryLife is an intelligent load output function that prevents damage caused by running batteries completely flat. It allows you to configure a voltage at which the SmartSolar disconnects a load. If a 100% recharge isn't achieved daily due to poor weather, it incrementally raises the disconnect voltage until success is met, thereby maintaining battery health and extending its life. Installation Notes Mount the charge controller in a well-ventilated, dry location, away from direct sunlight and heat sources. Ensure all wiring is correctly sized for the expected current and voltage, adhering to local electrical codes. Always connect the battery to the charge controller first, before connecting the solar PV array. Observe correct polarity for all connections to prevent damage to the unit and other system components. Refer to the official Victron Energy manual for detailed installation instructions and safety guidelines. Before You Buy PV Voltage Compatibility: Verify that your total solar array's open circuit voltage (Voc) will not exceed 145V under the coldest conditions. Battery Voltage: Confirm your battery bank operates at 12V, 24V, 36V, or 48V. Note that 36V requires manual software selection. PV Current: Ensure your PV array's short-circuit current (Isc) does not exceed the controller's 40A limit. System Sizing: Calculate your total PV power to ensure it aligns with the controller's nominal PV power ratings for your chosen battery voltage. Product specifications are subject to change by the manufacturer. Always verify compatibility with your specific system components before purchase and installation.
