Lumiax MPPT MT3075BT 30A charge controller

The MT series MPPT controller is based on the advanced Maximum Power Point Tracking (MPPT) technology and is designed for photovoltaic (PV) systems. The Bluetooth interface ensures constant data monitoring in the mobile application.

Main features:

• LCD display, easy reading of work data
• Real-time energy statistics function
• Automatic 12 / 24 V detection
• Flexible battery selection: Liquid, Gel, AGM and Lithium
• Extended service life thanks to a remote temperature sensor
• The controller is protected against overheating by a built-in power limiting function
• It also has a four-stage charging process: MPPT, boost, equalize, float
• Double automatic protection against too high charging power and too high current
• Multiple receiver modes: Always on, Dusk to Dawn, Evening and manual mode
• Bluetooth communication
• Mobile application for Bluetooth communication
• Monthly job data can be counted and displayed graphically
• Modbus protocol with RJ11 based on RS-485 to maximize communication possibilities
• Fully automatic electrical protection function
