MPPT MT3075 30A 12/24V charging controller

The LUMIAX MPPT MT3075BT 30A 12V/24V Charge Controller is a modern solar controller designed for use in off-grid photovoltaic systems. It utilizes MPPT (Maximum Power Point Tracking) technology and an advanced maximum power point tracking system, allowing it to increase PV system efficiency by approximately 20–45% compared to traditional PWM controllers. The MT3075BT version is additionally equipped with a Bluetooth interface, which allows for wireless monitoring of operating parameters and basic configuration via a mobile app.

The controller supports 12V and 24V systems, works with PV panels with voltages up to 55V and a total power of up to 390W (12V) and 780W (24V) A four-stage charging process (MPPT, Boost – pulse, Equalize – equalizing, Float – maintaining), battery type selection (liquid, gel, AGM) and extensive safety features (electrical protection against overcharging, deep discharge, reverse polarity, short circuit and overheating) ensure long battery life and the safety of the entire system. A large LCD display and real-time energy statistics function facilitate diagnostics and optimization of the installation.

Applications – where to use the MT3075BT

The MT3075BT 30A controller is ideal for:

• solar systems in campers, caravans, and campervans,
• PV systems on boats and yachts (12V/24V systems),
• holiday homes, gazebos, allotment gardens – lighting and small consumers,
• small off-grid installations with energy storage (12/24V batteries),
• street/garden lighting (Standard, D2D, "street light" modes) 2–9h),
• Micro-installations for CCTV monitoring, IoT systems, and telemetry.

Thanks to high tracking efficiency (>99.9%) and charge conversion (up to 97%), as well as support for panels with voltages up to 55V, the MT3075BT allows for efficient use of PV panel surface area and reduced cable losses (higher PV voltage possible).
