Common Questions
What is 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, ensuring maximum energy is harvested and delivered to your batteries, especially in varying weather conditions.
How do I monitor the SmartSolar MPPT 150/35?
The controller features built-in Bluetooth, allowing you to connect wirelessly to the VictronConnect app on your smartphone, tablet, or computer. This app provides real-time data, historical logs, and allows for advanced configuration of charging parameters.
Can this controller charge a 36V battery bank?
Yes, the SmartSolar MPPT 150/35 supports 36V battery systems. While it auto-selects for 12V, 24V, and 48V, the 36V setting can be manually configured using the VictronConnect app.
What battery types are compatible?
This controller is compatible with a wide range of battery types, including AGM, Gel, Flooded (wet cell), and Lithium (LiFePO4) batteries, especially those with an internal Battery Management System (BMS).
Installation Notes
- Ensure correct battery voltage selection for your system.
- Connect the battery first, then the solar panels, to prevent damage.
- Use appropriate cable gauges for PV and battery connections to minimise voltage drop.
- Mount the controller in a well-ventilated area, away from direct sunlight or heat sources.
- Refer to the official Victron Energy user manual for detailed wiring diagrams and safety instructions.
Before You Buy
- Verify your solar panel array's open circuit voltage (Voc) does not exceed 150V.
- Confirm your total PV power is within the controller's limits for your battery voltage (e.g., 500W for 12V, 2000W for 48V).
- Ensure compatibility with your battery type and charging requirements.
- Consider any additional accessories, such as a VE.Direct cable for PC connection if Bluetooth is not an option.
- Professional installation is recommended for optimal performance and safety.
Always verify product specifications and compatibility with your specific solar system components before purchase. This Victron SmartSolar MPPT 150/35 (SKU: VSSM150-35) is backed by a 5-year manufacturer's warranty.
