4.6 Cable Connection
Cable connection from the parallel box to the inverter:
"BAT+" to "BAT+";
"BAT-" to "BAT-";
"BMS" to "BMS".
*It is recommended to protect the cables by using corrugated pipe.
*If you plug the cable into the wrong port, you can insert the power cable disas-
-semblingtool into the gap on the side of the joint to unplug the cable easily.
* Please refer to "battery connection" section of the inverter's user manual/quick
installation guide for details about inverter connection.
Remember to always keep the unused port plugged.
NOTE!
NOTE!
Step 1. Prepare a 6 mm² BAT cable. Use a wire stripper to strip the 7mm insulation
layer of the wire end.
Step 2. Tighten the cable with the insulation layer stripped and insert it into the
battery pin contacts, make sure all wires are well connected.
Step 3.Tighten the BAT pin needle and the wiring harness to make the connection
tight without looseness.

• The DIP switch is used to configure the communication between battery
module(s) and the device. By default, only two groups of batteries can be
matched for use.
• The black-start function is only used in an off-grid application and when
there is no other power supply. To Black-start, hold down the button for 20
seconds until the soc light starts flashing blue to indicate successful black-start.
If the box is started in the black-start mode, remind that even when there is no
BMS communication, the port still contains high voltage with risk of electric
shock.
If the BMS communication has still not been established within 3 minutes after
starting the black-start mode, it indicates that the black start fails to start.
• After the BMS Parallel box- G2 is powered on, if the indicator lights Ⅱ
alternate flashing red and green for more than two minutes, and then change
to green flashing with the inverter reporting “Batt_ClusterCommuCountMis-
-Match", please check the communication connection of the second group of
BMS Parallel box- G2, as well as the power-on status of T-BAT H 5.8 or Ⅱ
MC0600 connected to the second group.
• After the BMS Parallel box- G2 is powered on, if the indicator lights Ⅱ
alternate flashing red and green for more than three minutes, and then change
to flashing red for one second and off for three seconds, with the inverter
reporting "BMS_Internal_Err 1", it indicates that the corresponding slave at
position 1 failed to connect to the communication successfully. According to
the error number, please check if the communication line of the slave at the

Verify the model number of each battery module to ensure that they are all the
same model.
Frequently pressing the POWER button may cause a system error. Allow at least 10
seconds after pressing the POWER button prior to making another attempt.
5.3 Status Indicators
The LED indicators on the front panel of the BMS and the battery modules indicate
the operating status.
The capacity indicators show the state of charge (SOC):
When the battery module is neither charging nor discharging, the indicator
lights are off.
When the battery module is charging, a part of the blue LED flashes once
every 5 seconds, and a part of the blue LED is on. Take SOC 60% for instance,
when in charging state:
1) The last two blue LED indicators are on
2) The third blue LED indicators flash once evey 5 seconds
When the battery module is discharging, the blue LED indicators flash once
every 5 seconds. Take SOC 60% for instance, when in discharging state:
1) The last three blue LED indicators flash once every 5 seconds

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 ortemperature, is
beyond design limitations. Boxperiodically reports its operating state to the inverter.
When the box falls outside the prescribed limits, it entersinto a warning state.
Use the monitoring software on the inverter to identify what caused the warning.
The possible warning messages are as follows:
Troubleshooting
When a warning is reported, the inverter immediately stops its operation.
1) Ensure the power cable is
correctly and properly connected
to the power connector (XPLUG)
of the BMS
2) If the first step still does not
work, contact your distributor or
our company directly.

To shut down the system and dismantling the box, please follow the steps below:
According to the actual situation, please turn off the breaker located between
the inverter and the parallel box.
Press the POWER button to shut down the box.
Move the circuit breaker switch to the OFF position.
Ensure that every indicator on the box is off.
If the batteries have not been used for more than 9 months, these batteries
must be charged to at least SOC 50 % each time.
For the first installation, the interval among manufacture dates of battery
modules shall not exceed 3 months.
If a battery is replaced or added for capacity expansion, each battery's SOC
should be consistent. The max. SOC difference should be between ±5%.
If users want to increase their battery system capacity, please ensure that
the SOC of the existing system capacity is about 40%. The manufacture
date of the new battery shall not exceed 6 months; in case of exceeding 6
months, please charge the new battery to around 40%.
