Wind & Solar Hybrid MPPT Controller – 12V/24V/48V

Wind & Solar Hybrid MPPT Controller designed for small off-grid wind/solar systems, including hybrid street-light applications. The controller manages wind-generator and solar-panel charging to a battery system and provides configurable DC load output.

Functions and Features

• Wind generator MPPT boost charging.
• PWM wind dump-load control with external dump-load resistance and intelligent solar charging disconnection.
• Dual power supply: battery + solar.
• LCD displays wind, solar, battery and load voltage/current/power information; selected parameters are user configurable.
• DC load output with three operating modes.
• Controller circuit board uses conformal coating for resistance to dust, moisture and static electricity.

Safety Information

• Inspect the product for transport damage before installation.
• Installation and electrical work must be performed by qualified professional personnel.
• Do not disassemble or attempt repairs without professional guidance.
• Do not operate the controller without batteries.
• Do not disconnect the controller from the batteries while the controller is operating normally.
• Keep children away from the controller.
• Do not allow water or snow to enter the controller.
• Tighten all power connections and use cables suitable for the system to avoid excessive heating.

Protection Functions

Physical Dimensions

• Controller size: 167 x 145.5 x 61.8 mm.
• Package size: 360 x 250 x 120 mm.
• Net weight: 1.9 kg.
• Gross weight: 2.3 kg.

Installation Notes

• Read the installation instructions before mounting or wiring.
• Disconnect all power sources before installing or adjusting the controller.
• Keep the controller away from water, snow, corrosive gas and strong electromagnetic interference.
• Choose a location that allows safe installation, electrical connection and later maintenance.

Wiring Sequence and Connections

• Dump load: connect the external dump-load positive and negative terminals to the controller as indicated by the terminal markings.
• DC load: connect load positive and negative correctly, avoid short circuit, and do not exceed the rated load current.
• Battery: connect battery positive and negative correctly. The controller must not be operated without the battery connection.
• Solar PV: connect PV positive and negative correctly. PV can produce hazardous voltage in sunlight; reverse polarity is prohibited.
• Wind generator: connect the three wind-generator leads to the wind input terminals. For safer connection, connect in breeze or windless conditions; high-speed wind-generator connection should only be made while the controller is operating.

LCD and Operation

• OK key: long press for more than 3 seconds to enter settings; use it to move to the next setting item; long press again to save parameters and exit.
• Previous/Increase key: moves to the previous browsing item; in settings it increases the selected value, with long-press for faster adjustment.
• Next/Decrease key: moves to the next browsing item; in settings it decreases the selected value, with long-press for faster adjustment.
• Esc key: returns to the main browsing interface; in settings it moves to the previous setting item; long press for more than 3 seconds exits without saving.
• If no key is pressed for approximately one minute during setting, modified parameters are not saved and the controller returns to the browsing interface.

Display Information

• Battery voltage, battery capacity percentage, battery current, battery power and cumulative output.
• PV voltage, PV current and PV power.
• Wind-turbine voltage, current and power, including charging/braking indication.
• Load operating mode, load power, load current and load fault code.
• Controller temperature and temperature status code.
• System-voltage status for 12V, 24V and 48V systems, including automatic-recognition modes.
