Product Description

8A Smart 5 Stage PWM Solar Panel Regulator Charge Controller 12V 24V Auto System Voltage

Advanced PWM Technology

The MT504-8A utilizes PWM (Pulse Width Modulation) technology to efficiently control electric power within motor coils. This method regulates output power by rapidly switching the output ON and OFF while maintaining constant voltage operation with consistent pulse periods.

5-Stage Smart Charging

This controller features advanced 5-stage charging technology including soft start, bulk charge, absorption charge, equalization charge, and float charge. The soft start stage provides optimal charging when battery voltage is low, while equalization charge prevents battery sulfation during extended use, significantly extending battery life.

Battery Compatibility

Designed to work with 4 battery types: AGM, GEL, WET, and LiFePO4 Lithium batteries. The battery type can be easily selected using the DIP switch on the back for optimal charging performance.

Durable Construction

With an IP67 waterproof rating, this controller is ideal for harsh environments including RVs, boats, and marine applications where exposure to moisture is common.
