Solar Charge Controller 80A Key benefits Reliable charge regulation for 12V and 24V systems with automatic battery voltage recognition to simplify installation. Fast dual USB output including Type C for convenient 5V device charging while managing solar charging at the same time. Built for demanding environments with wide operating temperature range and robust ABS housing that keeps the unit light and easy to mount. Main features Model size: 80A nominal charging current. Other available current options include 70A and 100A. Automatic 12V and 24V adaptation for plug and play operation when battery voltage is present at first installation. USB output: 5V for two USB ports plus Type C fast charging protocol to speed up phone and battery recharging. Interface: DC5521 connector for simplified connection and reduced wiring complexity. Material and weight: durable ABS construction, approx. 120 g. Operating temperature: 35 C to +60 C. Output mode: USB. Scope of application: designed for use with photovoltaic panels and related solar installations. Safety and protection functions Builtin protections include reverse discharge prevention, undervoltage protection, reverse connection protection, overload protection, and short circuit protection. Accumulation of operating hours for monitoring use. The controller generates heat during operation; install on a flat, well ventilated surface to maintain performance. Battery compatibility and usage notes Designed for common battery types including open, sealed, and gel leadacid batteries. The controller can also support 12V lithium ion and LFP battery packs on models that include lithium compatibility or when manual battery type selection is available. Confirm the unit supports lithium or set battery type manually before use. Do not use with NiMH or other unsupported battery chemistries. Only use photovoltaic panels as the charging source. Do not use DC supplies or other non solar sources for charging. Installation tips Ensure the battery has sufficient voltage at first connection so the controller can correctly identify 12V or 24V. Mount the controller as close to the battery as possible to minimize voltage drop from long wiring, which can affect voltage sensing. Allow clearance for ventilation; the unit will warm during operation.
