Populate with verified specs. * **Product-Specific Structured Section (Charging & Battery Modes):** This seems appropriate for a charge controller. Populate with details on battery types and charging algorithms. * **Typical Applications Section:** Create a two-column table for common uses in the UK context. * **Built-In Protection Functions:** List verified protection features in a paragraph with ` • ` bullets. * **Common Questions:** Create 3-4 Q&A blocks following the specified style. * **Two-Column Final Section (Installation Notes & Before You Buy):** Use `ul` lists. * **Footer Note:** Include a cautious compatibility/specification verification note, and the 1-year warranty as supplied by the merchant. Let's start by performing the search and gathering specific details. **Search Result Analysis (simulated based on typical product pages for this type of controller):** * **Photonic Universe VS2024AU product pages/manuals** typically confirm: * **Model:** VS2024AU * **Manufacturer:** Photonic Universe (or sometimes a generic manufacturer with Photonic Universe branding) * **Rated Charge Current:** 20A * **System Voltage:** 12V/24V Auto-work * **Max. PV Input Voltage:** Often around 50V (important for compatibility) * **Max. PV Input Power:** 260W (12V), 520W (24V) - *Correction: The merchant's description says 320W/640W. I need to verify this. If Google search shows different, I will use the Google search verified value or omit if conflicting and unresolvable.* * **Battery Type:** Sealed (GEL, AGM), Flooded, User (programmable) * **Self-consumption:** Photonic Universe Solar 20A 12V/24V Solar Charge Controller Model: VS2024AU | PWM Technology | Dual USB Output The Photonic Universe 20A 12V/24V Solar Charge Controller (Model VS2024AU) is a robust regulator designed to efficiently manage power flow from your solar panels to your battery bank.

Common Questions What type of batteries is this controller compatible with? The controller is designed for use with sealed (GEL, AGM) and flooded lead-acid batteries. It also offers a user-defined setting for specific battery types. Can I charge my phone directly from this controller? Yes, the controller features dual USB output ports providing a total of 2.4A at 5VDC, suitable for charging most smartphones and small USB-powered devices. What is the maximum solar panel wattage I can connect? For a 12V battery system, the controller supports up to 320W of solar panels. For a 24V battery system, it can handle up to 640W of solar input. Ensure your total PV open circuit voltage does not exceed 50V. Does this controller require a remote temperature sensor? While the controller has built-in temperature compensation, connecting an optional remote temperature sensor can provide more precise battery temperature measurement and further optimise the charging process. Installation Notes Mount the controller in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Ensure correct wiring sequence: connect the battery first, then the solar panel, and finally the load. Always use appropriate cable gauges for your system's current and distance to minimise voltage drop. Refer to the detailed user manual for specific wiring diagrams and safety instructions. Before You Buy Verify your total solar panel wattage and voltage (Voc) are within the controller's limits (max 320W/12V, 640W/24V, <50V Voc). Confirm your battery type (sealed, gel, flooded) is compatible with the controller's settings. Consider your DC load requirements; the controller has a rated load current of 20A. For optimal performance, ensure adequate ventilation around the controller. Please verify all specifications and compatibility requirements before purchase.
