Solar Controller, Size 50A, Blue Overview A compact solar charge controller designed for 12V and 24V systems with automatic voltage identification. Provides efficient battery charging control, low standby current, and basic load management for small off grid and mobile power systems. Key benefits Efficient charging control that monitors system voltage and manages charging to maximize battery use and prevent overcharge. Simple, clear connections for battery, solar panel, and load so installation is straightforward. Low standby current to reduce drain on the battery when the system is idle. Two USB outputs for convenient device charging at 5V up to 2A total. Main features Automatic 12V or 24V system identification. Rated charging current range listed in specifications. Rated discharge current of 30A. Maximum photovoltaic input voltage 50V. Two USB outputs, maximum 5V and 2A. Standby current less than 10 mA. Operating temperature range from minus 35 to plus 60 degrees Celsius. Durable PVC housing in blue. Physical dimensions: 180 x 90 x 45 mm. Basic connection steps 1. Connect the battery to the controller at the battery positive terminal and battery negative terminal. 2. Connect the photovoltaic module to the controller at the solar positive terminal and solar negative terminal. 3. Connect the load or consumer to the controller at the load positive terminal and load negative terminal. Do not reverse positive and negative connections at any time. Safety and usage notes Ensure correct polarity when connecting battery, solar panel, and load. Reversing polarity can damage the controller. Match the solar panel open circuit voltage and the battery voltage to the controller specifications. Strict compliance is required to avoid damage. Allow for a 1 to 3 cm variation in physical measurements and slight color differences due to display settings and lighting.
