Solar Charge Controller 12V/24V Auto 10A for Small Solar System

This 12V/24V auto solar regulator is a versatile solar charge controller featuring a PWM solar charge controller, making it universally compatible with lead-acid batteries (OPEN, AGM, GEL) and providing efficient solar power management for various applications.

To use the controller, follow these simple steps: First, connect the battery; second, connect the solar panel; and third, connect the load.

To adjust the float voltage, the system default is 13.7V, but you can change it according to your needs. Press the MENU button to enter the parameter page and find the floating charge voltage page. Then, in the floating charge voltage interface, long press the MENU button for 3-5 seconds to enter the setting, and use the UP or DOWN buttons to set the desired floating voltage.

The controller's key specifications are as follows: Rated Voltage: 12V/24V Input Current: 10A Output Current: 10A Max PV Voltage: 50V Max PV Input Power: 130W (12V) or 260W (24V) USB Output: 5V/2A Self-consumption: <10mA Operating Temperature: -35°C to +60°C Size/Weight: 1337034mm/154g Suitable for: Lead-acid batteries (Flood, AGM, GEL)

The package includes a 10A Solar Charge Controller and an English User Manual. Please note that this controller can only use photovoltaic panels as charging power and should not be used with DC or other power sources. The LCD display may have a voltage error of 0.2V to 0.3V, which is normal. If an old battery's capacity has degraded after hundreds of cycles and drops below 8V, the controller will shut off, and the LCD screen will go blank. To maintain good heat dissipation, please keep the controller in a cool and well-ventilated place.

Regarding common questions and answers: Q: Why does the LCD screen become blank? A: When the battery voltage is too low (≤8V), the controller will stop outputting, and the LCD will become blank. After the solar panels charge the battery and it returns to 12.6V, the controller will re-output.

Q: How can I set the controller to charge the battery during the day and turn on the load at dusk? A: Press the [DOWN] button to manually turn the load ON/OFF on the main display. (The load cannot be switched manually in the light control state.) There are three working mode options: 1. [24HR] - Load output 24 hours 2. [1-23HR] - Load on after sunset and off after the set hours 3. [0H] - Dusk to Dawn

This solar charge controller with dual USB 5V/3A output ports supports mobile phones, tablets, and other 5V devices, making it a versatile charging solution. It also provides reliable protection features, including over-current, short-circuit, reverse connection, low voltage, and overcharge protection, ensuring the safety of your devices.

The built-in industrial microcontroller offers automatic management and stores user-set parameters even when the battery is depleted. The informative LCD display allows for quick and convenient monitoring of status and data, facilitating mode switching and parameter configuration.

For easy setup, just connect the battery first, then the solar panel, and finally the load. Adjust settings easily using the single-button operation. This product comes with a 30-day money-back guarantee and a 12-month warranty for quality-related issues, ensuring your satisfaction and peace of mind.
