Important Safety Warning

Before Using the controller, please read all instructions and cautionary markings on the unitand 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

2.1 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 optional.

Product Installation

3.1 Installation Notes

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

3.2.3 Electrical Connection

Chart 6: System Overview

Please connect those parts according to the order of ①②③, and notice the following items.

1. Connect Dump load to the controller terminal “DUMPLOAD” by using copper conductor cable.
2. Connect the battery bank to the controller by the terminal which marks “DC Bus”. (do not reversed the connection of positive and negative terminals)
3. When wind turbine is still or running in a low speed, connects its output cable to the “WIND INPUT” terminal on the controller.
4. Check all the connection to make sure they are connected rightly and tightly.

Operation Interface Introduction

4.1 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.

4.2 LCD Information Define

from over voltage
| Flickering means over -discharge
Browse button| | Press it to enter next LCD display.
Press it for 5s to enter the brake status
Press it for another 5s to recover charging status.
Dump load indicator light| | Red light is on means the machine is on unload status or brake status.
The light is off when it works normally.

Trouble Shooting

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.
