Solarmax 30A Solar Charge Controller for 12V/24V Solar Power Systems

The Solarmax 30A solar charge controller is a PWM-based regulator designed to protect and manage battery charging in off-grid solar power systems. It regulates power from solar panels to prevent overcharging, deep discharge, overload, and short circuits, helping extend battery life and improve system reliability.

This controller supports automatic 12V and 24V system detection and features an LCD screen that displays charging status, battery level, load status, and system parameters. Dual USB ports provide convenient 5V output for charging small devices such as phones and power banks, making it ideal for home, lighting, and small solar installations.
