Qoltec MPPT solárny regulátor nabíjania s teplotným senzorom 20A | 12V / 24V | LCD | 2 x USB | GEL | LiFePO4

The Qoltec MPPT Solar Charge Controller is a high-efficiency device designed to optimize the charging of your battery bank from solar panels. With a rated charge current of 20A and auto-detect system voltage of 12V or 24V, it ensures maximum power extraction from your PV array. The integrated temperature sensor provides accurate temperature compensation, extending battery life. The clear LCD display shows real-time system status, and dual USB ports allow convenient charging of mobile devices.

Advantages

MPPT technology achieves over 99% tracking efficiency, significantly outperforming PWM controllers. Supports multiple battery types including Sealed, Gel, Flooded, and LiFePO4, with adjustable charging parameters. Comprehensive protection features safeguard against overcharge, overdischarge, overload, short circuit, reverse polarity, and over-temperature. Low self-consumption of less than 10mA ensures minimal power loss.
