Common Questions
What is MPPT technology?
MPPT (Maximum Power Point Tracking) technology allows the charge controller to find the optimal voltage and current at which solar panels produce maximum power. This results in significantly higher energy harvest compared to traditional PWM controllers, especially in varying weather conditions or when panel voltage is higher than battery voltage.
Can I use this controller with lithium batteries?
Yes, the PTR2210AN is compatible with lithium batteries. To enable lithium battery charging, you will need to select the appropriate charging program using the PC software or mobile app, which connects via the RS485/RJ45 port.
What is the maximum solar panel power I can connect?
For a 12V battery system, the maximum recommended solar panel power is 260W. For a 24V battery system, it is 520W. The controller has a 20A current limiting function, allowing for some flexibility in panel sizing.
How do I monitor and adjust settings?
The controller features a built-in LCD screen for real-time parameters. For advanced monitoring and programming, it can connect to a remote meter (MT50), a Wi-Fi module for mobile app access, or directly to a PC/laptop via an RJ45 to USB cable using the free Solar Station Monitor software.
Installation Notes
- Always connect the battery to the charge controller first before connecting the solar panels.
- Ensure correct polarity for all connections (solar panel, battery, and load) to prevent damage.
- Mount the controller in a well-ventilated area, away from direct sunlight and heat sources, to ensure optimal performance and heat dissipation.
- Use appropriate cable gauges for your solar panels and battery bank to minimise voltage drop and ensure safety.
- Refer to the detailed user manual for specific wiring diagrams and operational instructions.
Before You Buy
- Verify your battery system voltage (12V or 24V) and ensure it matches the controller's auto-detection capabilities.
- Confirm your total solar panel power does not exceed 260W (for 12V systems) or 520W (for 24V systems).
- Check that your solar panel's open-circuit voltage (Voc) does not exceed 100V, especially in cold temperatures.
- Consider if you require advanced monitoring or lithium battery support, as these features require additional accessories (remote meter, Wi-Fi module, or PC cable) and software configuration.
- Ensure you have adequate space for mounting the controller and access for wiring.
Please verify all specifications and compatibility requirements before purchase. Product specifications are subject to change by the manufacturer. This product is typically supplied with a 1-year manufacturer warranty.
