Important Safety Warning
Before Using the controller, please read all instructions and cautionary markings on the unit and this manual. Store the manual where it can easily be accessed.
This manual includes all safety warnings, installation, and operation guidance of MWM wind controllers.
- Before installing and using this controller, read all instructions and cautionary markings on the controller and all appropriate sections of this guide.
- Do not use the machine in the place where has flammability and explosive gas/articles. Beware of flames and sparks.
- Please Contact our after-sales person if the machine doesn’t work.
- Do not change the electrical components and parts yourself, or we will not be responsible for the warranty items and related duties.
- Please disconnect the AC input and DC output from controller before install or maintain the machine. Besides, do not touch the controller in 5 mins after disconnection.
- Please install the machine indoor to avoid the rain water enter the controller inside.
- Please keep good ventilation and heat dissipation.
- Please install a circuit breaker outside the controller if conditions are allowed.
- Please use copper cable for line connection, and choose the right diameter of cable according to the actual current.
- To avoid a risk of fire and electric shock, make sure the existing wiring is in good condition and that the wire is connected tightly.
- Do not restart the controller immediately when it alarms. Please analyze the fault reasons and repair them at first.
Basic Information
Introduction and Features
The MWM series wind power generation controller is the controller which integrates MPPT control and charge and discharge control. The power curve can be set by setting the wind turbine voltage and current, which can ensure the wind turbine work with the best power output all the time.
Features:
- Can be applied to grid-tied system, off-grid system and grid-tied energy storage system. Charge function is optional.
- MPPT track point settable
- Complete protection function
- Electrical components and parts in high quality.
- Several functions are optional, such as PV control function, wind speed measure function, rotational speed control function and temperature compensation function.
- RS232/RS485/RJ45/GPRS/Bluetooth/Zigbee optional. ( It can be monitored by app for those with GPRS/Bluetooth/RJ45 connection)

Product Installation
Installation Notes
- The machine should be kept indoors and well ventilated;
- Environment temperature: -20～+40℃; Humidity: <=95%，no condensing
- Altitude should not be more than 4000m (＞1000 m derating according to the GB/T3859.2regulations).
- Avoid using the machine in direct sunlight, sun exposure, rain, humidity, acid fog, and dust.
- The machine can only charge for the battery in the rated voltage range.
- The machine can only be connected to the wind turbine and PV with allowed power and voltage.

Installation Steps 
Electrical Connection
Chart 6: System Overview
Please connect those parts according to the order of ①②③, and notice the following items.
- Connect Dump load to the controller terminal “DUMPLOAD” by using copper conductor cable.
- Connect the battery bank to the controller by the terminal which marks “BATTERY”. (do not reversed the connection of positive and negative terminals)
- When wind turbine is still or running in a low speed, connects its output cable to the “WIND INPUT” terminal on the controller.
- Check all the connection to make sure they are connected rightly and tightly.
Operation Interface Introduction
LCD Display
After the power is connected, the whole screen is in a browsing status. It shows battery voltage, and can be changed to the following information by press related buttons.
LCD Information Define 
Trouble Shooting
| Fault Type | Description | Possible reasons and solutions |
|
No display on LCD | The connection between the battery and the controller is not tight | Check the wiring, and reconnect it. |
| DC breaker is not on between battery and controller | Turn on the breaker | |
| Low battery voltage | The system parameters are not matched correctly. Recheck the label and parameters on the machine. | |
| The battery doesn’t work. Change a new one. | ||
| Battery is connected in wrong polarity to battery input terminals. | Need change the internal fuse in controller, and reconnect the battery. | |
| No charging | The connection cable between wind turbine and controller is loose. | Reconnect and fix the cables. |
| Wind turbine output voltage hasn’t reached the charging voltage, | Check whether the system voltage is reasonable. | |
| Wind turbine is in “Brake” status | Wait the wind turbine recover if it brakes automatically. Press the button for 5s to release the brake status if it brakes by hand. | |
| Battery is already fully charged. | Check if the battery voltage has reached its output overvoltage. |
