KKTAU 60A Solar Charge Controller, Solar Panel Charge Controller 12V 24V Dual USB Charge Regulator Intelligent, Adjustable Parameter Backlight LCD Display and Timer Setting ON/Off Hours

Product Questions: 1. Q: How many watts (W) of solar panels can be connected A: 30A Within 360W, 40A Within 480W, 50A within 600W, 60A within 720W. 2. Q: Does this controller support lithium batteries? A: The new controller can be used for lead-acid and lithium batteries. 3. Q: My solar panel is 36V 200W, can I charge 12V battery? A: To charge a 12V battery, the working voltage of the solar panel can be between 17V and 23V, and for a 24V battery, the working voltage of the solar panel can be between 36V and 46V. Please make sure that the working voltage of the power supply and solar panels are within this range. If it is too high, the controller will be damaged. 4. Q: Can the inverter be connected to the load side of the controller? A: Please connect the inverter directly to the battery and not to the load terminal of the controller. 5. Q: Does the controller have requirement for battery capacity? A: No, as long as the voltage corresponds to it (but the maximum current of the board and the battery capacity should correspond). For example, the current of the solar panel is 5A, the battery capacity is preferably 50 AH, the current of the solar panel is 10A, and the battery capacity is preferably 100 AH. Do not use a large board to charge a small battery, which may be dangerous. 6. Q: How do you connect the solar panels, batteries, and controllers? A: Please be sure to connect the battery first (to ensure that the battery is fully charged), then connect the solar panel. When disassembling, please remove the solar panel first, then remove the battery, please connect it exactly as this order, otherwise the controller and other components probably damaged.
