This compact solar charge controller automatically manages and protects your 12V or 24V battery system while giving you clear, realtime information and convenient device charging. Key benefits Automatic compatibility: autodetects 12V or 24V systems so installation is straightforward and error across a wide range of solar setups. Know what's happening: the LCD display shows realtime charging currents and cumulative energy data, so you can monitor production and battery input at a glance. Extend battery life: triplestage charging (bulk, absorption, float) applies the correct charging profile to reduce stress on batteries and maximize usable life. Charge devices directly: dual USB outputs provide convenient 5V/5A charging for phones, tablets, and other USB devices without needing a separate adapter. Features and how they solve problems Automatic voltage recognition: removes the guesswork and prevents incorrect voltage selection, reducing installation time and risk of damage. LCD monitoring of currents and cumulative power: helps you track system performance, spot drops in production, and verify expected energy harvest over time. Triplestage charge control (bulk, absorption, float): delivers the right charge at each stage to avoid overcharging, overheating, or undercharging common in simpler controllers. Dual USB ports (5V/5A): keeps small devices powered during travel or offgrid use, eliminating the need to tap into the main battery output for USB charging. Practical applications Recreational vehicles and camper vans: manage solar input, protect the house battery bank, and keep phones or GPS charged while on the road. Offgrid cabins and boats: monitor daily energy production and ensure batteries are charged efficiently for reliable power overnight. Camping and outdoor day trips: run a small solar panel to maintain battery state and power USB devices for navigation, lighting, and communication. Performance and compatibility Designed for 12V and 24V solar battery systems with automatic detection for simple setup. Provides realtime current readout and cumulative power tracking on the LCD for performance visibility. Implements industrystandard bulk, absorption, and float charging stages for safer, longerlasting batteries. Includes dual 5V/5A USB outputs for convenient device charging. This controller combines automatic voltage handling, clear monitoring, proven charging logic, and builtin USB charging to simplify installation, protect batteries, and keep devices powered during daily use or offgrid adventures.
