Efficiently manage your off-grid solar system with this 30A PWM Solar Charge Controller. Designed for 12V and 24V lead-acid battery systems, this controller automatically detects the system voltage and regulates charging to help maximise battery performance while protecting against overcharging, over-discharging and reverse polarity.

Featuring an integrated industrial-grade microcontroller with automatic memory retention, the controller stores your settings even after power loss. The easy-to-read LCD display provides real-time system information, while the dual USB ports allow you to conveniently charge phones, tablets and other 5V USB devices directly from your solar power system.

Suitable for caravans, RVs, off-grid solar installations, solar lighting, remote monitoring systems and other small renewable energy projects, this controller incorporates multiple electronic protection features for reliable everyday operation.
