High Efficiency 40A MPPT Solar Charge Controller
Advanced MPPT Technology | 12V/24V Auto-Detect | Up to 1040W PV Input
The Photonic Universe PTR4210AN is a high-efficiency 40A MPPT solar charge controller designed to optimise power harvest from your solar panels. Utilising advanced Maximum Power Point Tracking (MPPT) technology, this controller ensures your solar system operates at peak efficiency, significantly outperforming standard PWM controllers. It automatically detects 12V or 24V battery systems and can handle solar panel arrays up to 520W for 12V systems or 1040W for 24V systems, with a maximum open-circuit voltage of 100V.
Ideal for a wide range of off-grid and grid-tied solar applications, the PTR4210AN is particularly effective when solar panel voltage is considerably higher than the battery voltage, such as charging a 12V battery with 36V solar panels. Its comprehensive electronic protection features and advanced monitoring capabilities provide a robust and reliable solution for managing your solar power system.
MPPT EFFICIENCY: Achieves greater than 99.5% tracking efficiency and up to 98% conversion efficiency for optimal energy yield.

Common Questions
What is MPPT technology and why is it beneficial?
MPPT (Maximum Power Point Tracking) technology allows the controller to continuously find and track the optimal voltage and current point of your solar panels. This ensures maximum power extraction from the PV array, leading to significantly higher charging efficiency compared to traditional PWM controllers, especially in varying weather conditions or when panel voltage is higher than battery voltage.
Can this controller charge lithium batteries?
Yes, the Photonic Universe PTR4210AN 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. This allows for customisation of charging parameters specific to your lithium battery type.
What communication options are available for monitoring?
The controller offers multiple communication methods: it can connect to an optional MT50 remote meter, a Wi-Fi module for mobile app monitoring (Android/iOS), or directly to a PC/laptop via an RJ45 to USB cable for monitoring and programming with the free Solar Station Monitor software.
What is the maximum solar panel input voltage?
This 40A MPPT solar charge controller can accept a maximum solar panel open-circuit voltage (Voc) of 100V. This wide input voltage range provides flexibility in solar panel configuration.
Installation Notes
- Mount the controller indoors in a well-ventilated area to ensure adequate heat dissipation.
- Always connect the battery to the controller first before connecting solar panels.
- Ensure all power connections are tight to prevent excessive heating.
- Install appropriate external fuses/breakers as recommended by local electrical codes.
- The controller features negative common grounding.
Before You Buy
