MPPT Solar Charge Controller 12-30A BC PRO LCD Display

The MPPT Solar Charge Controller 12-30A BC PRO is a high-efficiency charge controller designed for off-grid solar systems. Featuring advanced Maximum Power Point Tracking (MPPT) technology, it maximizes energy harvest from solar panels, ensuring optimal battery charging. The backlit LCD display provides real-time system data, making monitoring easy.

Advantages

With MPPT tracking efficiency >99.5% and conversion efficiency >98%, this controller significantly improves energy yield compared to PWM controllers. It supports multiple battery types including lead-acid and lithium, and features auto-sensing system voltage (12/24/48V). The common negative design simplifies wiring, and built-in protections ensure safe operation.
