Industrial microcontroller: Builtin industrial microcontroller provides stable, reliable control and precise charging algorithms. Adjustable parameters and clear display: Large LCD shows operating status and settings; all key parameters can be adjusted to match system requirements and battery types. Comprehensive protections: Builtin short circuit protection, open circuit protection, reverse connection protection, and overload protection reduce risk to the system and help maintain steady operation. Compatibility: Supports both 12V and 24V battery systems. Select the appropriate current rating and input limits to match panel arrays and battery capacity. Performance notes Maximum solar input is specified per current rating and battery voltage. Use the listed 25V input limit for 12V systems and 50V input limit for 24V systems to avoid exceeding controller specifications. Choose a controller current rating that matches or slightly exceeds the expected charging current to maintain safe operation and longevity. Typical use scenarios Offgrid cabin or small home: Charge a 12V or 24V battery bank from roofmounted or groundmounted solar arrays. The MPPT algorithm helps extract maximum power during variable irradiance. Recreational vehicle or boat: Manage charging for onboard 12V or 24V batteries while monitoring charge status on the LCD. Builtin protections help prevent wiring mistakes from damaging the system. Remote equipment and monitoring: Power DC loads and charge batteries for remote sensors, communications equipment, or lighting systems where reliable, efficient charging and fault protection are required. Installation and selection guidance Confirm battery system voltage (12V or 24V) before selecting the controller. Match the controller current rating to expected PV short circuit current and battery charging current, and observe the listed maximum PV input wattage for the chosen battery voltage. Ensure wiring, fuses, and breakers are sized appropriately and installed according to local electrical practices. What this product solves Maximizes solar energy harvesting with MPPT charge control.
