Key benefits Automatic 12V/24V detection: installs easily into existing solar systems and automatically configures itself for either 12V or 24V setups — no manual voltage switching required. Protects and extends battery life: built-in industrial controller with 3-stage charging management (bulk, absorption, float) charges batteries efficiently and prevents overcharging, undercharging and excessive cycling. Clear, adjustable monitoring: large LCD shows voltage, current, charge status and settings; parameters can be adjusted to match your battery and system requirements. Direct device charging: two USB outputs provide up to 2.5A combined for charging phones, tablets or other USB devices from your solar setup. What it does and why it matters Reliable charging control: the controller manages charging in three stages to deliver the right current and voltage at each phase of battery charge, improving performance and extending service life. Easier system management: the large LCD and adjustable settings let you monitor system health and fine-tune charging behavior without additional meters or guesswork. Flexible deployment: automatic 12V/24V compatibility makes the unit suitable for a wide range of solar applications, avoiding compatibility issues when upgrading or changing batteries. Primary features Automatic detection and operation for both 12V and 24V systems Built-in industrial controller with 3-stage charging management Large LCD display with adjustable parameters for voltage, current and charge modes Two USB charging ports capable of delivering up to 2.5A for mobile devices Typical use scenarios Outdoor and landscape lighting: manage and protect battery banks for park lights, garden pathways or remote decorative lighting where reliable, low-maintenance charging is required. Advertising and signage: power and control solar-charged billboards and signs that run overnight, ensuring consistent illumination and longer battery life. Marine and small-boat installations: supply battery charging and convenient USB charging for devices on boats and marine installations where 12V/24V compatibility and safe charging are essential. Performance and compatibility notes Designed for solar energy systems using 12V or 24V battery banks; automatically detects system voltage on installation. Charging managed in three stages to maximize battery efficiency and lifespan while maintaining safe operation. Two USB ports allow on-site charging of mobile devices directly from the solar system (combined output up to 2.5A). Who should choose this controller Anyone installing or maintaining small- to medium-sized solar systems who needs reliable, automatic voltage compatibility, clear monitoring, and controlled charging to protect batteries and power devices. Suitable for residential and commercial outdoor lighting, signage, and marine applications where dependable charging and simple user control are priorities.
