30A Solar Panel Battery Charge Controller with Builtin Protections, 12V/24V Auto LCD Regulator and Dual USB level benefits Protects your battery and solar system from common faults so equipment runs reliably and lasts longer. Automatically selects 12V or 24V systems, removing guesswork during installation and reducing setup time. Provides clear system status and charging information on an LCD screen, making monitoring simple. Dual USB outputs let you charge mobile devices directly from the controller without extra adapters. Key features and functions Rated charging current: 30A for steady solar to battery charging. Automatic system voltage detection: supports both 12V and 24V battery systems. LCD regulator: displays charging status, battery voltage, and operating mode for quick diagnostics. Builtin protections: short circuit protection, open circuit protection, reverse polarity protection, and overload protection to safeguard the controller and connected equipment. Dual USB outputs: convenient onboard ports for charging phones, tablets, and other USB devices while the solar system is operating. Regulator functionality: prevents overcharging and helps maintain healthy battery voltage levels. Compatibility and practical details Designed for use with solar panels and 12V or 24V battery banks commonly found in small offgrid systems, RVs, boats, cabins, and portable power setups. Works with typical lead acid and sealed battery systems commonly used in solar setups. Confirm battery type and settings before final connection. Compact footprint for easy installation in tight spaces. Clear terminal labels and wiring points make connections straightforward. Performance and reliability 30A capacity handles moderate solar array sizes and battery banks for home and mobile applications. Multiple protection mechanisms reduce the risk of damage from wiring errors, faulty loads, or panel faults. LCD feedback improves troubleshooting and ongoing system management without additional meters. Use scenarios 1. RV or camper: Connect roofmounted solar panels to charge your onboard battery bank while monitoring voltage and charging status on the LCD. Use the dual USB ports to charge phones and tablets during travel. 2. Remote cabin lighting and battery maintenance: Maintain a small battery bank that powers LED lighting and a few essential loads. The controller reduces overcharge risk and displays system status for easy checks during visits. 3. Weekend outdoor events or mobile worksite: Set up a portable solar array to keep batteries topped up and provide USB charging for phones and small devices without running a generator. What you get A 30A solar charge controller with automatic 12V/24V selection, LCD regulator, dual USB outputs, and comprehensive builtin protections for safe operation. Notes for installation Verify system voltage before connection and follow safe wiring practices. Use appropriately sized wiring and fuses for the solar array and battery to match the 30A rating. Consult the product manual for detailed wiring diagrams and configuration options. This controller provides a compact, monitored, and protected way to regulate solar charging for small to medium offgrid systems while offering convenient device charging through integrated USB ports.
