2. Safety Information

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the unit, personal injury, or property damage. Keep this manual for future reference.

• Ensure all connections are correct and secure before applying power.
• Always connect the battery first, then the load, and finally the solar panel. Disconnect in the reverse order.
• The regulator is only suitable for lead-acid batteries (OPEN, AGM, GEL). It is not compatible with nickel-hydride, lithium-ion, or other battery types.
• Ensure your battery has sufficient voltage for the controller to recognize it before the first installation.
• The working temperature of this controller is -35°C to 60°C. During hot sunny days, the temperature outside might reach 60-75°C. Please keep the controller in a cool and well-ventilated place to maintain good heat dissipation.
• Do not use an electric screwdriver to tighten the screws on the terminals.
• This device is for indoor use only. Protect it from water and moisture.

3. Product Overview

The GCSOAR Solar Charge Controller is a Pulse Width Modulation (PWM) device designed to manage power flow from your solar panel to your battery and load. It features a clear LCD display for monitoring system status and easy parameter adjustment.
