All operators of the energy storage system shall follow the user manual, installation and
service manuals and quality guarantee. Any damage to equipment caused by ignoring and
misreading the user manual, installation and service manuals and quality guarantee will
invalidate the product warranty.
2.2 Qualified electrician
Qualification
A qualified electrician is a person who possesses the required knowledge, technical
6
training and experience, to conduct the following:
Setting up, activating, deactivating, disconnecting, grounding, short-circuiting and
repairing electrical circuits and devices.
Standard maintenance and use of protective devices defined in the safety standards.
Administering first-aid to injured parties.
Compliance with local regulations, applicable standards and directives.
Battery Maintenance
When the device is not used for a long time, discharge the battery to between 45%
and 60% of the battery capacity, and disconnect the battery output to avoid the battery
power being emptied;
When the device is not used for a long time, it is recommended to charge the battery
once every six months to ensure that the battery can work normally.
Ensure reliable grounding.
Battery maintenance must be carried out by professionals or under their direction;
When replacing the battery, use the same type and number of batteries or battery
packs;
Warning: Do not throw the battery into a fire. The battery may explode;
Warning: Do not open or damage the battery. The electrolyte flowing out of the battery
is harmful to the skin and eyes. The electrolyte may also be toxic;
Warning: The battery may cause a shock hazard and a large short-circuit current.
When handling the battery, pay attention to the following aspects:
a) Remove watches, rings and other metal products;
b) Use a tool with an insulated handle;
c) Wear rubber gloves and shoes;
d) Do not place tools or metal parts on the battery;
e) Disconnect the charging power supply before disassembling the battery terminal
block;
f) Pay attention to whether the battery is inadvertently grounded. If you find that
thebattery has been accidentally grounded, remove the power supply from theground.
Touching any part of the grounded battery can cause an electric shock. Disconnecting
ground during installation and maintenance reduces the probability of electric shock
(applicable to equipment without a grounded power supply and remote battery power).

After finishing all the connections, comprehensively check and ensure cables are well
connected. Then close the MINI ES 3kW/3kWh &MINI ES battery base breaker.
Shown as below:
31figure24. the position of circuit breaker on MINI ES battery base
NOTICE!
• Please ensure wago connectors are not under strain to avoid bad connection. A
comprehensive checking is required after completing the connection.
4.7. Trial operation of device
Check before trial operation
Please refer to chapter 4.3 in the MINI ES 3kW/3kWh installation manual check before
operation.
Supply power and start
CAUTION!
Before startup the System, the installer need to disconnect the circuit
breaker and carry out the following inspection:
• Double check and make sure the connection is correct according to the manual
instruction.
• Ensure that MINI ES3kW/3kWh and MINI ES battery is fixed tightly
DANGER!
Risk of short circuit
Incorrect wiring may cause short circuit.
Short circuit test shall be performed before system commissioning.
Only close the MINI ES circuit breaker on grid supply to system.
Press “Power” button for 10s, and start the system
Note: Long press "POWER" button for about 5seconds, "power" lamp ring light ( press the
32"power" button for about 10 seconds, "power" lamp ring turn off, system shutdown.)
It’s a normal phenomenon that during the start-up process that "power" for "local" "remote"
lamp ring will flicker at the same time when waiting for circle power lamp ring light.
After “POWER" lamp ring light, “POWER” indicator light flashes around 1-2 minutes, this
is a normal phenomenon that self-test process during the system start-up time. After self-
inspection ended, “POWER" and "LOCAL" indicator lights will keep lighting, then the
system is completed start-up.
Check “POWER” “LOCAL” indicator light;
Normal condition： “POWER”indicator light is always on, at the same time“LOCAL”
indicator light is always on. Display as follow.
REMOTE LOCAL POWER
figure25. Normal state
Fault state: "POWER" indicator light is flashing. (MINI Battery base and MINI ES
3kW/3kWh did not connect successfully)
"LOCAL" indicator light is flashing. (Not connect to grid or no electricity power from grid)
Record results are as follows:
Configure MINI ES 3kW/3kWh &MIINI ES battery base
CAUTION!
• work can be carried out only after the wiring of MINI ES 3kW/3kWh and MINI ES
battery base finished.
• Ensure that the circuit breaker of MINI ES 3kW/3kWh and MINI ES battery base
have been closed and the system start-up before configuration.
Note: More information can be viewed "MINIES monitoring software using manual"
After the completion of the MINIES external wiring work, start-up the MINIES, and use the
monitoring software provided by BYD to configure MINIES

Confirm that the UT-850 converter has been connected to the computer and MINIES.
Choose UT-850 actual occupation port of COM, set up the station address (slave
34address) 4, baud rate 9600 b and other data default, click on "open serial port", then you
can open the serial communication.
If the communication parameters are not configured properly, or the converter is
connected with problem, the interface will pop up prompt box that the communication
timeout, please double check the communication parameter configuration or the
converter line connection.

Only after the user login that the configuration of MINI ES 3kW/3kWh &MINI ES battery
base can be proceeded.
Click on “Control” on the upper left corner of the select page, and choose the “Parameter
Config” in the drop-down menu.

After finish the configuration, need shutdown MINI ES, and disconnect the circuit
breakers of MINI ES 3kW/3kWh and MINI ES battery base. After completing the closing
action, once again closed the circuit breakers of MINI ES 3kW/3kWh and MINI ES battery
base, and restart the system. Then re-enter into the BECU configuration interface, if the
number of BECU display is 2, the configuration is successful. And check the “Group
Status” on the home page, if the status display b00000001, said that currently only MINI
ES 3kW/3kWh merged. If the status display b00000010 said that only MINI ES battery
base merged currently; if the status display b00000011 said MINI ES 3kW/3kWh and
MINI ES battery base has been successfully incorporated.
37figure35. Check the “Group Status”
Check running information of MINI ES 3kW/3kWh and MINI ES battery base.
Enter the “Debugging” interface, click on “Debug Advanced” at the bottom right corner,
set the number of PCS to 1, BECU number to 2 and click “Confirm”.
figure36. Set the PCS and BECU number
After completing the above configuration, enter the “info Device”, you can view the
running information of MINI ES 3kW/3kWh and MINI ES battery base.
