This solar charge controller is designed to provide safe, stable, and efficient charging for off-grid solar systems. Equipped with a large LCD display, it allows real-time monitoring of system status and easy parameter adjustment. The controller supports multiple battery types including lead-acid and lithium batteries, ensuring flexible application. Built-in intelligent protection functions effectively prevent overcharge, over-discharge, overload, and short circuits, extending battery lifespan. With dual USB ports and multiple load working modes (24H, light control, light + delay), it is ideal for home solar systems, lighting, and small power applications.
1. The LCD screen clearly shows voltage, current, and system status;
2. Multiple intelligent protections ensure safe operation and extend battery life;
3. Dual USB ports allow convenient charging for phones, tablets, and other devices;
4. The alloy backplate provides efficient heat dissipation for stable performance;
5. Flexible load modes support 24H, light control, and light+timer operation;
6. Durable ABS housing is impact-resistant, flame-retardant, and long-lasting.
Step1: Connect the 03battery to the 01controller first (correct polarity required).
Step2: Connect the 04load to the 01controller (ensure correct polarity).
Step3: Connect the 02solar panel to the 01controller.
Important: Always follow this connection sequence to avoid damage to the controller.
