Solar PWM Charge Controller 30A, 12V 24V with LCD and Dual USB This compact solar charge controller manages up to 30A of charging current for 12V or 24V lead acid battery systems. Designed for reliable everyday use, it offers clear LCD feedback, simple onekey configuration, and builtin protections to keep your solar system stable and safe. Key benefits Simple setup and monitoring: LCD display shows system status at a glance and onekey configuration makes initial setup fast. Automatic memory stores settings after power loss. Efficient PWM charging: PWM load management optimizes battery charging and extends battery life when used with compatible lead acid batteries. Device charging on the go: Dual USB outputs provide convenient charging for phones, tablets, and small electronics directly from the solar system. Robust protection and temperature management: Builtin protections include short circuit, open circuit, reverse connection, and overload protection. Dual MOSFET reverse current protection reduces heat generation for safer operation. What it does and how it solves problems Regulates solar module output to safely and efficiently charge 12V or 24V lead acid batteries, preventing overcharge and reducing battery stress. Provides reliable load control for DC lighting and small DC appliances while protecting against wiring errors and fault conditions. Offers clear status reporting so you can diagnose system conditions without additional tools. Specifications and important attributes Type: Solar power meter / PWM charge controller Current output: 30A System voltage: 12V or 24V automatic detection Display: LCD Interface: Dual USB outputs for device charging Material: PVC housing Color: Blue Controller core: Builtin industrial microcontroller Features: Onekey configuration, automatic memory, full PWM load management Protections: Short circuit, open circuit, reverse connection, overload Cooling: Dual MOSFET reverse current protection for lower heat production Compatibility and limitations Suitable only for lead acid batteries: OPEN, AGM, GEL. Not suitable for nickel metal hydride or lithium ion battery chemistries. Intended only for use with solar modules as the charging source. Do not connect other charging sources to the controller. Safety and installation notes Before first installation, ensure the battery has sufficient voltage for the controller to detect battery type. Keep the battery cable as short as possible to minimize voltage drop and power loss. Follow the correct connection sequence to avoid damage: 1. Connect the battery plus and minus to the charge controller. The display will show 1 for 12V detection or 2 for 24V detection. 2. Connect the photovoltaic module plus and minus to the controller. 3. Connect the load plus and minus to the controller. Reverse this when uninstalling. Incorrect connection sequence can damage the controller. Included condition statement Unit is brand . All parts are tested and quality controlled prior to shipment. Practical use scenarios Offgrid cabin lighting and device charging: Manage a small solar array to charge a 12V battery bank, power LED lighting, and charge phones via the dual USB ports. Camper van or caravan solar system: Provide automatic 12V or 24V battery regulation for onboard batteries, protect against wiring errors, and offer USB charging for devices. Remote shed or workshop power: Control DC loads such as fans or LED strips while regulating battery charging from a rooftop or panelmounted solar module. What to expect A durable PVCbodied controller in blue that mounts easily in small solar installations, offers straightforward controls, and protects connected batteries and loads with multiple builtin safety features.
