This solar charge controller is designed for small offgrid systems to charge batteries safely and efficiently from photovoltaic panels. It combines boost MPPT charging with automatic voltage detection, userfriendly LCD display, and multiple safety protections for reliable everyday use. Key benefits Efficient charging even at low input power thanks to boost MPPT technology, with a maximum conversion rate up to 98 percent. Simple installation and configuration: automatically detects system voltage and supports parallel connections to scale capacity. Clear system monitoring and easy settings via an LCD and button interface that show voltage, current, power, mode, temperature, and other parameters. Protects batteries and connected devices with multilevel safety features and charging parameters. Main features Automatic voltage identification: works with 12V, 24V, 36V, and 48V systems. MPPT boost charging: threestage charging process — constant current (MPPT), constant voltage (absorption), and floating charge. Controller power source: photovoltaic panels. Supports lithium, leadacid, and other battery types; supports multiple controllers in parallel. LCD display and button interface: shows operating status, warnings, photovoltaic voltage and current, charging power and current, battery voltage and remaining capacity, load status, and temperature. Safety and protection Photovoltaic overcurrent protection Load overload protection Load short circuit protection Photovoltaic reverse connection protection Battery reverse connection protection Overheat protection Selfdiagnosis function to evaluate and prevent photovoltaic array short circuit overcharge and overdischarge settings What is included 1 x Solar charge controller Practical applications Small offgrid systems where safe, efficient battery charging is required Home solar setups and lighting systems Marine applications such as boats and dock equipment Street lighting and other remote or distributed loads powered by photovoltaic panels Notes for use Designed to be powered by photovoltaic panels; ensure panel output matches the expected input voltage range. Configure battery type and charging parameters via the LCD and buttons before regular operation. Parallel connection is supported to expand system capacity; follow proper wiring practices and local electrical codes during installation.
