30A Solar Charge Controller Replacement PWM Controller with LCD and Dual USB Product overview This 30A solar charge controller provides reliable PWM charging and builtin protections for 12V and 24V solar systems. Housed in a durable PVC case and finished in blue, it includes an LCD display for system status and two USB outputs for charging mobile devices. Key benefits Reliable battery charging and longer battery life through PWM load management and automatic regulation. Clear system monitoring with an LCD display and onekey configuration for quick setup. Builtin protections prevent common faults including short circuit, open circuit, reverse connection, overload, and reverse current. Dual USB output lets you charge phones, tablets, and other USB devices directly from the system. Memory function preserves user settings so no reset is required after a drained battery. Efficient thermal design with dual MOSFETs for reverse current protection and low heat generation. Specifications Type: Solar power meter / charge controller Material: PVC Color: Blue Current output: 30A System voltage: 12V or 24V (autodetect) Display: LCD display Interface: Dual USB outputs, 5V 2.5A maximum combined Main features Builtin industrial microcontroller for stable control and accurate monitoring. Onekey configuration, digital display, and automatic memory of settings. Full PWM load management for efficient charging control. Multiple safety protections: short circuit, open circuit, reverse connection, overload, and reverse current protection via dual MOSFETs. Low heat production for reliable longterm operation. Compatibility and condition Compatible with 12V and 24V leadacid battery systems including OPEN, AGM, and GEL types. Not suitable for nickel metal hydride or lithiumion battery chemistries. Intended only for regulation of solar modules; do not connect other power sources to the controller. Condition: 100 percent brand ; all parts tested and quality controlled prior to shipment. Package includes: 1x solar charge controller replacement unit as pictured. Safety and installation notes Ensure the battery has sufficient voltage for the controller to detect battery type before first installation. Keep the battery cable as short as possible to minimize voltage loss. Follow the correct connection sequence to avoid damage: first connect the battery to the controller (plus and minus), then connect the photovoltaic module, and finally connect the load. When uninstalling, reverse this . An incorrect sequence can damage the controller. Typical applications Offgrid home or cabin solar lighting and battery charging. RV, caravan, or marine installations for battery management and device charging. Small commercial or remote installations such as signage, monitoring stations, or backup systems. Why choose this controller This 30A PWM controller combines straightforward setup, essential protections, and device charging capability in one compact unit. It is a practical aftermarket replacement for 12V or 24V leadacid solar systems where dependable regulation, user convenience, and safety protections are required.
