COMMISSIONING

Switch on the Battery System Requirements:

• The battery and the inverter must be properly installed and fixedo
• All cables must be correctly connected.

Steps:

1. Turn the external protection switch between the high voltage box and the inverter from OFF to ON. @Turn the high voltage isolation switch of the high voltage box from OFF to ON.
2. Turn the low voltage button switch of the high voltage box from OFF to ON.
3. After startup, the system enters the self-check mode, the color belt is light-blue breathing light. After the self-check, the light-blue breathing light changes to blue and the battery system starts to work properly.

If it is failed to switch on the battery system.
CONTACT OUR LOCAL AFTER-SALE SERVICE WITHIN 48 HOURS.

Light meaning

Self-check

| Light-blue light, breathing at normal rate If the duration exceeds 1 minute, restart the battery or contact maintenance personnel.
---|---
Fault| the red light is steady on when the system in faulty.

Normal

| The blue light is steady on by default. If no PCS communication is available, the light switches to the breathing mode.
Alarm| Orange light, the light is always on when the insulation alarm is triggered .
Charging| Green light, breathing at normal rate.
Note :| After the single module undervoltage alarm or total undervoltage alarm is triggered , the  light belt breath at a slower rate with the orange color. After the single module is less than 2.3V but greater than OV, the RGB light function is turned off and will turn on again until the SOC is<C1 5%.

In addition to the LED lights, the battery fault information can be obtained through the screen and the upper computer. DEYE can also read these information through remote WLAN connection.

Switch off the Battery System

Steps

1. Turn the low voltage switch of the high voltage box from ON to OFF, and wait for 2 seconds until the blue button light goes off.
2. Turn the high voltage isolation switch of the high voltage box from ON to OFF.
3. Turn the external protection switch between the high voltage box and the inverter from ON to OFF If two or three battery systems are connected in parallel, please firstly switch off the first battery which has a communication connection to the inverter, and then switch off all the other batteries.

SAFETY DESIGN

1. The battery system cannot be turned on if the battery is incomplete or is not installed properly.
2. The system will automatically shut down if the battery does not communicate with the inverter for 24 hours.
3. The system will automatically shut down if the battery or inverter installation error occurs for 10 minutes.
4. The system will automatically shut down if the voltage is too low within 60 seconds.

Main and User Interface
The default interface will appear after powering on. If the screen is not touched for more than 13 minutes, it will darken and the default interface replaces the other interface. Click this screen to enter the user interface.

Click the “Portrait” button in the upper right corner to pop up the numeric keyboard. Enter the password “123” and click OK to enter the configuration interface. Click “BMU No” in the lower left corner, enter the number of BM Us and click “OK” to finish configuring the number of BM Us.

Basic Parameters

Fault Indication:
When the corresponding fault type occurs, the red background indicator on the screen will light up. Refer to 6.2 for details.

In addition

1. If the communication between the battery and the inverter is not connected, the breathing light will be light-blue. Please check the communication between the inverter first.
2. When the battery system startup, the breathing light belt is light blue and breathing flashes, and the battery system is in the state of self-check. If the light blue color remains for a long time .:1Ss, the system is in an abnormal state and cannot work.
3. When the red light is on, it indicates that the battery system is faulty. You can check the faulty information on the screen.
4. The battery system can repair the fault within a certain time itself; If the fault cannot be rectified, restart the battery. If the fault still exists after restart, contact after-service or technical support.

MAINTENANCE AND STORAGE

Cleaning
We recommend to clean the battery system regularly. If the battery housing is dirty, use a soft dry brush or dust collector to remove the dust. Do not use solvents, abrasives, or corrosive liquids to clean the housing.
