Upgraded 30A solar charge controller for 12V and 24V systems. It automatically manages the work of solar panels and batteries in your solar setup using a builtin industrial microcontroller. It remembers userset parameters so you do not need to reset when the battery voltage drops. It also provides dual USB outputs for charging devices via 5V/2.5A. Safe to use: Equipped with overcurrent protection, short circuit protection, reverse connection protection, low voltage protection, and overcharge protection, plus full 3stage PWM charging management. This controller helps safely boost system efficiency and extend battery life. LCD display: The screen shows status and data so you can easily switch modes and adjust parameters. Suitable for use in homes, industrial sites, and business environments. Multiple electrical protections: Builtin overcurrent protection, short circuit protection, reverse polarity protection, opencircuit protection, automatic recovery, and no damage to the controller, providing reliable protection for connected equipment.
