The Blue color 30A PWM Solar Charge Controller 12V/24V with USB is a high-performance solar charge regulator designed for efficient and safe solar power management in home solar systems, DC lighting systems, and off-grid installations. It automatically detects 12V or 24V system voltage and supports lead-acid batteries such as OPEN, AGM, and GEL. This intelligent controller ensures stable charging and discharging using advanced 4-stage PWM technology, which enhances battery performance and extends service life.

Equipped with dual USB 5V/3A output ports, the controller allows users to charge smartphones, tablets, and other USB-powered devices directly from solar energy. Its industrial-grade microcontroller automatically manages charging parameters, memorizes user settings, and protects connected loads and batteries from damage caused by overcharging, short circuits, and reverse polarity. Even if the battery power is drained, the system retains saved configurations thanks to the auto-memory function.

The LCD digital display provides real-time information about battery voltage, charging current, load status, and system mode. The one-key operation design makes it simple to change settings or switch modes, making it user-friendly even for beginners.

This 30A solar charge controller includes multiple electronic protections: over-current protection, short-circuit protection, reverse polarity protection, overcharge protection, low voltage cutoff, and open-circuit protection, ensuring a safe and reliable operation. Its dual MOSFET reverse current protection reduces heat generation and improves efficiency, making it ideal for long-term use in Bangladesh’s solar energy applications.

The controller is suitable for medium to large-scale solar systems, capable of handling up to 360W solar panels (12V) or 720W (24V), making it perfect for home solar installations, solar street lighting, rural electrification, camping power systems, and off-grid setups.

How to Connect:

1. Connect the battery to the controller first for system initialization.

2. Connect the solar panel to the solar input.

3. Connect the DC load or USB device to the output terminals.

4. Ensure all connections are secure and correct in polarity.

5. Avoid reversing terminals to prevent internal damage.

This controller’s blue body, digital LCD, and compact design make it durable, efficient, and well-suited for Bangladesh’s solar environment, ensuring consistent performance even in high temperatures.
