HQST 30A Solar Charge Controller - 12V/24V PWM Flush Mount For Lithium & Lead-Acid

Solar power users, this HQST 30A charge controller is exactly what you need to manage your off-grid solar system efficiently.

The flush mount design gives you a clean, integrated look when installed in your RV, cabin, boat, or solar power station.

It automatically recognizes 12V or 24V systems and works with sealed, gel, AGM, and flooded lead-acid batteries, plus you can manually set it for LiFePO4 lithium batteries.

The smart PWM charging uses three-stage charging (boost, float, equalization) for lead-acid batteries and two-stage for lithium, optimizing battery performance and extending lifespan.

With maximum solar input of 450W for 12V systems and 900W for 24V, it handles substantial solar arrays.

The negative ground design makes it compatible with most vehicle and off-grid systems, and it includes comprehensive protection against over-discharge, over-voltage, over-current, reverse current, short-circuit, and reverse polarity.

The backlit display is perfect for checking status in low light, and it automatically turns off after 20 seconds to save power.

Installation is straightforward with the included mounting hardware, and the terminal size accepts 8-14 AWG wires.

Whether you're powering an RV, remote cabin, marine system, or any off-grid application, this controller delivers reliable solar charge management that protects your battery investment while maximizing solar harvesting efficiency from your panels.
