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. This ensures that the maximum available power is extracted from your solar array, especially beneficial during changing weather conditions, leading to higher energy yields compared to traditional PWM controllers.
How do I monitor the SmartSolar MPPT 100/20?
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 performance logs, and allows for advanced configuration of settings.
What battery types are compatible?
The SmartSolar MPPT 100/20 is compatible with a wide range of battery types, including AGM, Gel, Flooded (wet cell), and Lithium (LiFePO4) batteries. It offers automatic voltage selection and specific charging profiles for each type to ensure optimal and safe charging.
Can I connect more solar panels than the nominal PV power rating?
The controller will limit the input power if more PV power is connected than its nominal rating. While this won't damage the controller, it means any excess power beyond the rated capacity will not be utilised. It's crucial to ensure the maximum PV open circuit voltage (Voc) and short circuit current (Isc) of your array do not exceed the controller's limits (100V and 20A respectively) to prevent damage.
Installation Notes
- Ensure correct battery voltage (12V, 24V, or 48V) is selected or auto-detected.
- Connect the battery to the controller first, then the solar panels.
- Adhere to specified wire gauges for safe and efficient operation.
- Mount in a well-ventilated area, away from direct sunlight and heat sources.
- Refer to the manufacturer's manual for detailed wiring diagrams and safety instructions.
Before You Buy
- Verify your total solar panel array's open circuit voltage (Voc) does not exceed 100V.
- Confirm your solar panel array's short circuit current (Isc) does not exceed 20A.
- Check the nominal power of your solar array matches the controller's capacity for your battery voltage.
- Consider your battery type (AGM, Gel, Flooded, Lithium) for optimal charging profile selection.
- Ensure you have a Bluetooth-enabled device for monitoring via the VictronConnect App.
Always verify product specifications and compatibility with your specific solar energy system components before purchase and installation. Consult a qualified installer for complex setups.
