1. 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 store flammable products within the same control room or area where the wind controller
is installed.
➢Do not open or dismantle any parts of the controller other than the required cable termination
cover where fitted.
➢Disconnect the AC input and DC output from controller before working on or maintain the
controller. Do not work on the controller within 5 minutes of de energization.
➢The controller is designed for indoor use only
➢Maintain ventilation as detailed in this manual
➢Install on noncombustible material only.
➢The DC supply to the controller must be fused.
➢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.
➢Use anti oxidizing past on all connections.

2. Basic Information
2.1 Introduction and Features
The AWS M series wind power generation controller is a 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 allows the wind turbine to operate within its best power output all the times.
(All AWS wind controller solar with AWS Wind turbines are preset, do not alter these setings)
Features:
➢Can be applied to grid-tied system, off-grid system and grid-tied energy storage system. Charge
function is optional.
➢MPPT tracking
➢Protection functions.
➢Solar PV integregrsation.
➢RS232/RS485/RJ45/GPRS/Bluetooth/Zigbee optional. (It can be monitored by app for those with
GPRS/Bluetooth/RJ45 connection)

3. Product Installation
3.1 Installation Notes
1) The controller must 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) Not to be installed in direct sunlight, sun exposure, rain, humidity, acid fog, and dust.
5) Ensure the correct battery voltage and polarity is connected to the controller.
6) The controller can only be connected to a wind turbine and PV within an the rated Voltage, current
and power characteristics.

Chart 6: System Overview
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 “BATTERY”. (do not
reversed the connection of positive and negative terminals)
3. Connect the wind turbine output to the “WIND INPUT” terminal on the controller ( in any order).
Insure a wind brake switch is installed at the tower and the brake is activated prior to connection.
4. Check all the connection to make sure they are connected rightly and tightly.

5. 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.

V1.3
１２
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.
