50A MPPT Solar Charge Controller, 12V/24V Auto, Bluetooth

MPPT solar charge controller delivers faster, more efficient battery charging with automatic 12V/24V detection and built-in Bluetooth monitoring for easy system control. Designed for off-grid solar, RV, marine, and home PV setups, it supports up to 50A charging and high PV input capacity while maintaining stable performance in hot or cold conditions. Works with common deep-cycle battery types including AGM, gel, flooded, and lithium.

• Delivers up to 98% MPPT conversion efficiency to reduce charge time and improve solar harvest vs PWM


• Fits 12V/24V systems with auto DC input sensing; supports up to 50A charging current


• Includes built-in Bluetooth module for remote monitoring and adjustments via a compatible app


• Supports Modbus via TTL interface for expanded integration and data communication


• Protects with reverse, short-circuit, overcurrent, and TVS lightning protection for safer operation

When your solar setup needs stable charging without constant manual checks, this MPPT controller keeps your batteries managed with fast, balance, and float charging modes plus optional external temperature sensor support. The current-limiting charging algorithm helps maintain reliability during high input power, while the wide operating range supports year-round use.
