Key features

• •Compatibility Guide: Engineered to efficiently manage all solar panels below 300W, this 20 amp solar charge controller is your system's reliable core. For complete safety and compatibility, it is designed solely for 12V batteries and is not compatible with 24V or 36V battery packs. Please note: This unit does not include a polarity converter and must be connected with correct positive/negative polarity
• •Upgraded 20A PWM Charging Controller: Designed for standard solar panels without a built-in controller, this Upgraded 20A PWM solar charge controller delivers double the current output of common 10A controllers. It utilizes optimized charging algorithms to manage power flow from panel to battery with superior efficiency and intelligence
• •Real-Time Status Monitoring: The upgraded LCD screen and LED indicators provide at-a-glance insight into your system's status. This solar charge controller 12v allows you to select the optimal charging mode for your specific battery type and visually track the charge level. Simply press the button to view the current for 5 seconds, after which the display automatically reverts to battery voltage
• •Plug & Play Upgrade: Experience a quick and secure connection with upgraded quality SAE connectors. This charge controller for solar panels is designed for effortless setup. (Note: Connect the solar panel first, then the battery, ensuring correct polarity)
• •Zero Battery Drain Technology: Our upgraded circuit design ensures this solar controller 12v consumes zero power when idle. Built-in diodes prevent reverse current, guaranteeing no battery drainage after the sun sets
• •Dual-Port Charging for Your Devices: Power your electronics directly from the sun or your battery using the convenient TYPE-C and USB output ports. This solar charge controller is compatible with any device that uses a TYPE-C or USB cable
