Upgraded solar charge controller for 12V and 24V systems. This controller automatically manages the operation of solar panels and batteries in your solar system using a builtin industrial microcontroller. It remembers various parameters set by the user, so no reset is needed when the battery runs down. You can also charge devices with dual USB outputs up to 5V/2.5A. Safe to use. Equipped with overcurrent protection, short circuit protection, reverse connection protection, low voltage protection, and overcharge protection, with full 3stage PWM charging management. This 30A solar charge controller helps safely increase system efficiency and extend battery life. LCD display. The LCD display keeps you informed of status and data. You can easily switch modes and parameter configurations, and use the controller in different settings such as home, industry, and business. Multiple electrical protections. Builtin over current protection, short circuit protection, reverse polarity protection, open circuit protection, automatic recovery, and no damage to the controller, providing reliable protection for your equipment. Use scenarios Offgrid home or cabin solar power system to manage charging and battery health. Recreational vehicle, boat, or caravan setups needing reliable solar control and device charging via USB. Remote industrial, telecom, or business installations requiring protection and automatic recovery to maintain system performance.
