PWM Solar Charge Controller 10A/20A/30A Dual USB for 12V/24V Systems

This new PWM solar charge controller is designed to regulate charging from a solar panel to a battery in 12V or 24V systems. It is offered in 10A, 20A, or 30A versions and includes dual USB ports for convenient device charging. Use it to help manage battery charging in small off-grid or backup power setups. Check the listing for details on compatibility, included accessories, and installation guidance. Free shipping is included with purchase.

Before you buy

• Ungraded cards can vary—zoom in on photos for surface, corners, and centering.
• If it’s a “pick your card/insert” listing, confirm the exact card name/number in the listing.
• Review shipping rules (combined shipping / envelope vs mailer) on the listing.

10/20/30A PWM Solar Panel Battery Regulator Charge Controller 12V or 24V Batteries with Dual USB Output - Black CaseThis PWM Solar Battery Charge Controller automatically manages and regulates the voltage and current to the battery from the solar panel(s). It incorporates short-circuit, open-circuit, reverse polarity, and overload protection in order to ensure that the batteries are not overcharged and that power isn't discharged from the batteries to the solar panels during shaded or dark conditions and drain the batteries. It comes with USB ports to charge for your phone and other electronic devices directly from the controller.This solar charge controller is perfect for smaller home, cabin, RV and other remote and portable solar systems.FeaturesThis controller is designed for use only with 12V and 24V lead-acid batteries. It cannot be used with lithium-ion, nickel-cadmium or other battery types.Regulates the voltage from the solar panels going to the batteries.Built-in industrial master chip to control the charge and discharge process with adjustable parameters to prolong the battery life cycle and stabilize power to the load.3-stage PWM charge management with short-circuit protection, open-circuit protection, and reverse polarity protection.Dual USB outputs with 5V/2A maximum power (across both outputs) can charge mobile phones, tablets, and other USB-powered devices.LCD display with backlight function displays status and parameters.Dual MOSFET reverse current protection, low power dissipation.Easy to install and operate, suitable for home, industrial, commercial, remote and portable solar energy systems.SpecificationsSize: Approx.13.3 x 7 x 3.5 cm/ 5.24 x 2.76 x 1.38 inch (LxWxH)Battery Voltage: 12V/ 24V (Auto recognition)Input Charging Current: 10A / 20A / 30A dependent upon the model chosen. The maximum panel output current should be about 25% less than the controller's maximum input current rating. For example, with a single 6A 100W panel, use the 10A model. Two 6A panels (12A total) should use the 20A model. If in doubt, use the higher current model, i.e. if the maximum panel output current is 9A, use the 20A model rather than the 10A modelMaximum Discharge Current: 10AInternal power consumption: =10mAOver Charge Protection:B01 Sealed: 14.4V/28.8VB02 Gel: 14.2V/28.4VB03 Flood: 14.6V/29.2VOver Charge Float: 13.7V/27.4VCharge Recovery Voltage: 12.6V/25.2VOver-discharge Protection: 10.7V/21.4VOver-discharge Recovery: 12.6V/25.2VUSB output: 5V/2A12V batteries should be used with solar panels capable of generating 18V-25V With 12V batteries, the maximum panel voltage must not exceed 25V24V batteries should be used with solar panels capable of generating 36V-50V With 24V batteries, the maximum panel voltage must not exceed 50VMaximum Power Output:10A (12V / 120W (MAX) 24V / 240W (MAX) )20A (12V / 240W (MAX) 24V / 480W (MAX) )30A (12 V / 360W (MAX) 24V / 720W (MAX) )Operating Temperature: -35 ~ +60CStorage Temperature: -35 ~ +60C Operation:Make sure your battery has enough voltage (typically 10V or more) to power on the controller and to recognize the battery type. The battery cables should be as short as possible to minimize losses.The regulator is only suitable for lead-acid batteries: Open, AGM, Gel. It is not suitable for nickel metal hydride, lithium ion or other battery types. Connection:Connect the battery to the charge controller first. The controller's LCD should turn on. Do not proceed if the LCD display does not turn on! Connect the photovoltaic module to the charge controller.Connect your load (the device(s) you are going to power) to the charge controller.Reverse these steps when disconnecting or uninstalling the controller.Package Includes:1X (1 Piece) 10A, 20A or 30A PWM Solar Charge Controller - Black Case Operating InstructionsNOTE: The solar panel and battery in the photo are shown to illustrate the controller's interconnections only. They are not included with the charge controllerWe also carry these PWM solar charge controllers with a BLUE faceplate rather than BLACK: 10/20/30/40A PWM Solar Panel Battery Regulator Charge Controller USB 12V 24V Blue Faceplate.Get it faster!
