HQST 30A 12V/24V PWM Flush Mount Solar Charge Controller Solar Regulator Negative Ground with Back lit Display for Lithium Sealed Gel Flooded Batteries

- 【Aesthetically Clean Installation】This HQST 30A PWM solar charge controller with flush mount capabilities is designed to be seamlessly mounted onto a flat wall surface, producing an aesthetically clean, and integrated look. - 【Negative Ground, Safe Charging】This is a commonly used negative-ground controller, suitable for most vehicle and solar off-grid systems. Equipped with multiple protections, including over-discharge, over-voltage, over-current, reverse current, short-circuit, and reverse polarity, this 30A PWM solar controller prevents damage from installation mistakes or system faults. - 【Compatible with Most Systems】Automatic battery recognition for 12V and 24V AGM, GEL, Flooded, and Sealed Lead-Acid batteries. Lithium batteries can be set manually. Supporting 12V (up to 450W) and 24V (up to 900W) solar systems, this solar controller can be widely applied on motorhomes, sheds, boats, water pumps, and more. - 【Smart PWM Charging】Utilizes the three-stage charging (Boost, Float, Equalization) algorithm to regulate the flow of electricity to achieve optimal battery (lead-acid) performance and longevity. Two-stage charging (Boost and Float) for lithium batteries. - 【Easy to Use】The backlit display allows you to see key information clearly, even in a dark environment. The USB-A port supports charging current up to 5V/1A for your mobile device, like a mini fan or smartphone. The compact design is ideal for areas with limited space.

An essential component of your off-grid solar system. Our HQST 30A flush solar charge controller allows you to keep your battery powered via solar panels wherever you happen to be - traveling by RV or maintaining a convenient and reliable solar-powered solution for your cabin or home.

HQST 30A PWM flush controller supports both 12V and 24V battery bank systems and can automatically identify the battery voltage once connected to a Sealed, Gel, AGM, and Flooded battery (manual setting is required for LiFePO4 battery).

Certified by CE and RoHS. Built with multiple protections, over-discharge, over-voltage, over-current, reverse current, short-circuit, and reverse polarity, this 30A PWM solar controller prevents damage from installation mistakes or system faults.

The backlit display allows you to see key parameters in the dark in real-time. The backlit display will auto off after 20 seconds, which is sleep-friendly. Tap any key to activate it again.

Measure the length and width of the flush mounting part. Cut a board or piece of paper of the same size.

Use the cut paper or board as a template to mark and reserve the installation area on the mounting wall. Slightly longer and wider than the measurements to ensure easier mounting.

Affix the charge controller to the mounting wall with the included four pairs of mounting screws.
