5.1 Configuring the Box

The DIP switch is used to configure the communication between battery module(s)
and the inverter. Detailed configuration information is detailed as follows:

6

7

Configuration activated by inverter:

0- Matching a single battery group(group 1 or group2).
1- Matching both battery groups(group 1 and group2).

CAUTION!

If DIP switch is 1, t he numb er of bat teries in each gro up must b e
the sa me.

Black-start Configuration

The black-start function is only used in an off-grid application and when there is no

other power supply.

If the box is started in the black-start mode, even when there is no BMS
communication, the port still contains high voltage with risk of electric shock.

After the black-start mode has started, if the BMS communication has still not been
established within 3 minutes, the black start has failed.

4- Matching one/two/three/four battery modules of single group (group 1 or group2).
4- Matching one battery module of each group (group 1 and group2).

5- Matching two battery modules of each group (group 1 and group2).
6- Matching three battery modules of each group (group 1 and group2).
7- Matching four battery modules of each group (group 1 and group2).

NOTE!

When powering on the box, the system will start self-testing. If the buzzer beeps,
it means the DIP configuration is in fault or communication failure has occured.
If the buzzer beeps check if the number of battery modules are corresponding
to the DIP configuration, and also check if the RS485 communication cables are
correctly connected. After checking that these two situations are set, press the
POWER button to power on, and press the POWER button again 10 seconds later.

In addition, the buzzer will only sound on the corresponding fault during the

power-on self-test. After the self-test has already been completed, it will not
beep again even if the same fault occurs.

1) The last three blue LED indicators flash once evey 5 seconds

5.4 Shutting Down the Box

To shut down the system, follow the steps described below:

1) Turn off the breaker between the inverter and box

2) Power off the BMS

3) Turn off the system by moving the circuit breaker switch to the OFF position

4) Ensure that every indicator on the box is off

5) Disconnect the cables

6 Troubleshooting

Check the indicators on the front to determine the state of the box.
A warning state is triggered when a condition, such as voltage ortemperature,

is beyond design limitations. Boxperiodically reports its operating state to
the inverter.

When the box falls outside the prescribed limits, it entersinto a warning state.
When a warning is reported, the inverter immediately stops its operation.

Use the monitoring software on the inverter to identify what caused the warning.

The possible warning messages are as follows:

your existin g system ca pacity's SOC is about 40% . The ex pansion
battery is requ ired to be ma nufactu red within 6 month s; If more than 6
months, recharg e the battery module to abo ut 40%.

•Maintain periodically

Only qualified person may perform the following works.
During the process of using the box,the manage person shall examine and
maintain the machine regularly.The concrete operations are as follows.

1) Check that if the cooling fins on the rear of house are covered by dirts,
and the machine should be cleaned and absorbed dust when necessary.
This work shall be check time to time.

2) Check that if the indicators of the box are in normal state,check if the keys of
