MPPT Solar Charge Controller (ST-MP Series)

Description

The ST-MP Series MPPT Solar Charge Controller is a reliable and high-performance solution for solar energy systems. Using Maximum Power Point Tracking (MPPT) technology, it extracts the maximum available power from solar panels, significantly improving charging efficiency compared to conventional PWM controllers. This intelligent controller supports multiple battery types (lead-acid, gel, AGM, lithium, etc.) and provides full system monitoring through its LCD display, which shows real-time voltage, current, and system status.

The device is engineered with multiple safety protections, including overcharge, over-discharge, reverse polarity, short circuit, and over-temperature protection. With its durable construction and wall-mountable design, the ST-MP Series is ideal for residential, commercial, telecom, and industrial solar applications.
