Common Questions
What is MPPT technology and how does it benefit my solar system?
MPPT (Maximum Power Point Tracking) technology continuously monitors the voltage and current of your solar panels to find the optimal power point. This ensures maximum energy extraction, especially during fluctuating light conditions, resulting in up to 30% more energy harvest compared to older PWM controllers.
How do I monitor and configure the SmartSolar MPPT 250/85?
The controller features built-in Bluetooth, allowing you to connect wirelessly via the free VictronConnect App on your smartphone, tablet, or computer. This app provides real-time data, historical performance logs, and enables full customisation of charging parameters.
What battery types are compatible with this charge controller?
The Victron SmartSolar MPPT 250/85 is compatible with a wide range of battery types, including AGM, Gel, Tubular Plate (lead-acid), and Lithium batteries. Its programmable charging algorithm allows for precise settings to match your specific battery's requirements.
Can this controller be used in a 36V battery system?
Yes, while the controller auto-selects 12V, 24V, and 48V, a 36V battery system can be manually selected and configured using the VictronConnect App or by connecting the optional plug-in LCD display.
Installation Notes
- Ensure adequate ventilation around the controller for optimal performance and longevity.
- Always follow the manufacturer's wiring diagrams and safety guidelines provided in the user manual.
- Use appropriately sized cables for PV input and battery connections to minimise voltage drop and ensure safety.
- Professional installation is recommended for complex solar power systems to ensure correct setup and compliance with electrical standards.
Before You Buy
