FLEXSOLAR 30A PWM (abbreviation of Pulse Width Modulation) solar charge controller is one of the most effective ways to regulate the voltage output from solar panels and out to a battery. It uses advanced 3-stage PWM modulation to get the most out of your AGM, GEL, or lead-acid batteries, and protect your battery charging from over-voltage, over-current and over-charging.
Multiple Security Protection.
Provides solar charge protections against over-load, over-current, over-charge, over-voltage, under-voltage, and short-circuit to your batteries.
Intuitive to Operate and Use
With a backlit LCD screen showing the voltage, it is intuitive to operate. And with inbuilt mount holes, it is easy to mount.
Great Compatibility & Automatic Detection
Compatible with GEL, Flood, and SEL batteries. Automatically detects 12V or 24V DC system voltages, and the LCD screen displays the solar charging and battery operation information, customizable parameters, and error codes.
