Feature 1、【High-definition LCD Display】: Our 100A Focused MPPT Solar Charge Controller features an LCD screen with backlight, providing clear and intuitive visualization of the system operation. Stay informed about the charging process even during nighttime. 2、【Intelligent Control for Versatile Compatibility】: This solar controller is equipped with a panel-style keypad for easy one-touch operation. With multiple adjustable parameters including float charge voltage, boost charge voltage, light control, and time delay, it offers intelligent control and supports compatibility with various battery types. 3、【Convenient USB Ports】: Featuring dual USB ports, our charge controller supports most USB devices such as smartphones, tablets, and PSP game consoles. Keep your electronic devices powered up wherever you go. 4、【Enhanced Wiring Capabilities】: The enlarged wiring interface can accommodate Φ16MM wires, providing a larger cross-sectional area and increased spacing between wires (7MM). This design enhances insulation performance, installation reliability, and reduces current voltage drop, minimizing power loss. 5、【Efficient Heat Dissipation】: Our 100A solar charge controller is equipped with thickenedaluminum alloy heat sinks, tightly locked heat dissipation plates made of M0S silicone film, and MQ5 tube lock heat dissipation plate design. This ensures uniform heat dissipation and allows the controller to operate normally even in high ambient temperatures of up to 60°C. Don't worry about malfunctions caused by temperature rise.
