Solar Charge Controller 10A/30A PWM 12V/24V LCD Dual USB

Solar Charge Controller 10A/30A – PWM 12V/24V with LCD Display & Dual USB

Take full control of your off-grid solar setup with this intelligent PWM Solar Charge Controller. Available in 10A and 30A variants, it automatically adapts to 12V or 24V battery systems, delivering smart battery management, real-time monitoring, and convenient dual USB charging — all in a rugged, weather-resistant housing built for outdoor use. Made in Mainland China.

Key Features

• Rugged Impact-Resistant Housing: High-strength, flame-retardant ABS shell provides excellent electrical insulation, impact resistance, and corrosion resistance — protecting internal components from dust, moisture, and minor collisions. Designed to extend device service life in harsh outdoor environments.
• Intelligent Full-Range Protection: Built-in high-precision MCU control chip continuously monitors battery status and automatically regulates charging/discharging current and voltage. Triggers overcharge, over-discharge, short circuit, and reverse connection protection to safeguard your entire photovoltaic system.
• Dual USB Fast Charging Output: Gold-plated USB contacts deliver a stable 5V output, enabling direct charging of smartphones, power banks, flashlights, and small electronics — no extra adapters needed. Perfect for off-grid convenience.
• Real-Time LCD Status Display: High-definition LCD screen on the wear-resistant ABS panel shows live voltage, battery capacity, charging status, and operating mode at a glance — no professional tools required.
• Easy Installation & Wide Compatibility: Reinforced ABS mounting brackets with pre-drilled holes support 12V/24V automatic voltage adaptation. Compatible with most small home solar lighting systems, RV solar setups, and outdoor monitoring power supplies — installation takes as little as 5 minutes with just a screwdriver.
• Customizable Parameter Settings: Waterproof, dustproof ABS sealed control buttons allow free adjustment of charging voltage, lighting control mode, and timing duration to suit diverse off-grid power applications.

Frequently Asked Questions

Q: What is the difference between the 10A and 30A solar charge controller versions?

A: The 10A version is ideal for smaller off-grid solar systems, such as compact home lighting or single-panel setups, while the 30A version supports larger photovoltaic systems with higher current demands, such as RV solar arrays or multi-panel outdoor installations. Both versions feature the same LCD display, dual USB ports, and 12V/24V auto-adaptation.

Q: Is this solar charge controller compatible with both 12V and 24V battery systems?

A: Yes — the controller features automatic 12V/24V voltage detection and adaptation, so it works seamlessly with either battery system without requiring manual configuration. Simply connect your solar panel and battery and the controller identifies the correct voltage automatically.

Q: Can I use the USB ports while the controller is regulating my solar battery?

A: Absolutely. The dual USB ports output a stable 5V power supply independently of the battery management functions, allowing you to charge smartphones, power banks, flashlights, and other small electronics simultaneously while the controller manages your solar charge cycle.

Q: How difficult is it to install this solar charge controller?

A: Installation is straightforward. The reinforced ABS mounting brackets include pre-drilled holes, and the whole setup process typically takes around 5 minutes using only a standard screwdriver. No advanced electrical knowledge is required for basic installation.
