Technical Specifications Parameter Value Rated Current 10A System Voltage 12V/24V Auto Max. Solar Input Voltage 50V Max. Solar Input Power (12V) 160W Max. Solar Input Power (24V) 320W Self-Consumption ≤8.4mA (12V) / ≤7.8mA (24V) Operating Temperature -35°C to +50°C Wire Terminals Up to 4mm² Dimensions (L x W x H) 13.8 x 6.9 x 3.7 cm Weight 130g Charging & Battery Modes The Photonic Universe 10A charge controller is designed for versatile battery management. It supports common lead-acid battery types, including sealed, gel, and flooded, with 'sealed' as the default setting. For specific applications, a user-defined battery type can be configured. Advanced customisation of charging parameters, such as battery type and capacity, charging voltages for different stages, and duration of each stage, is possible. This level of control allows for highly personalised charging profiles to maximise battery health and performance. Monitoring and programming capabilities are unlocked through optional accessories: the MT50 remote meter, a Wi-Fi module for smartphone control via a free app, or PC software ('Solar Station Monitor') using an RJ45 to USB cable. These interfaces provide access to critical system data and extensive customisation options. Typical Applications Application Description Campervans & Motorhomes Ensures leisure batteries are safely charged from solar panels, powering lights, pumps, and small appliances on the go. Caravans Maintains optimal battery charge for extended stays, preventing overcharge and deep discharge. Boats & Marine Systems Ideal for small to medium marine solar installations, protecting batteries in humid environments. Small Off-Grid Setups Suitable for sheds, workshops, or remote cabins requiring basic solar battery charging. Built-In Protection Functions This Photonic Universe charge controller incorporates a comprehensive array of safety mechanisms to safeguard your entire power system. These include robust protection against: Overcharge • Over-discharge • Overload • Short Circuits • Reverse Current (at night) • Overheating • PV Reverse Polarity • Battery Reverse Polarity. Common Questions What type of batteries is this controller compatible with? This controller is compatible with sealed, gel, and flooded lead-acid batteries. You can also define a user-specific battery type for tailored charging profiles using one of the optional communication methods. Can I monitor and adjust settings remotely? Yes, this controller offers advanced communication capabilities. You can connect an optional MT50 remote meter, a Wi-Fi module for smartphone app control, or link it to a PC via an RJ45 to USB cable for comprehensive monitoring and parameter adjustment. What is the maximum solar panel wattage it can handle? For a 12V battery system, the controller can handle up to 160W of solar input. For a 24V battery system, it can manage up to 320W of solar input. Does it protect against reverse current at night? Yes, the controller effectively prevents reverse current flow from the battery back to the solar panel during the night, ensuring your battery retains its charge. Installation Notes Always connect the battery to the controller first to allow it to recognise the system voltage (12V or 24V). Ensure correct polarity when connecting solar panels, battery, and load to prevent damage. Install the controller in a well-ventilated area, away from direct sunlight and moisture. Use appropriate wire gauges for your system to ensure safe and efficient operation. Consider installing external fuses/breakers as close to the battery as possible for added safety. Before You Buy Verify your total solar panel wattage does not exceed the controller's maximum input (160W for 12V, 320W for 24V). Confirm your battery type (sealed, gel, or flooded) is supported. If advanced monitoring or customisation is desired, consider purchasing compatible accessories like the MT50 meter or Wi-Fi module separately. Ensure you have adequate space for the controller's dimensions (13.8 x 6.9 x 3.7 cm). Consult the detailed instruction manual included with the product for full installation and operational guidance. Please verify all specifications and compatibility requirements before purchase. This product is covered by a 1-year manufacturer warranty.
