5.1 Configuring the Box
· 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 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 MC0600 connected to the second group. · After the BMS Parallel box- G2 is powered on, if the indicator lights 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 corresponding position is properly connected.

Commissioning
· The BMS Parallel box-II G2 must be connected to two groups of batteries simultaneously in order to function properly, and the number of slaves in both groups must be the same. The second group of BMS Parallel box-II G2 must contains a T-BAT H 5.8 or Mc0600. And the two battery circuits connected to the BMS Parallel box- G2 must be all HV11550 or all HV10230, and it is not allowed to connect one group with HV11550 batteries and the other group with HV10230 batteries. · It is prohibited to plug or unplug the power line during the operation of the BMS Parallel box- G2.
5.2 Commissioning
Verify the model number of each battery module to ensure that they are all the same model. After all battery modules are installed, please follow the following steps to start the box: 1) Open the waterproof cover board of the box; 2) Move the circuit breaker switch to “ON”; 3) Press the POWER button to start the box; 4) Reinstall the cover board to the box; 5) Turn on the inverter DC switch; 6) After starting the box, please confirm that the waterproof cover board is closed again.

(1) When both groups have faults, the status lights of the two

groups will flash red at intervals of 0.5 seconds. The general

status light will keep the red light on.

(2)When one of the two groups has a fault, and the status light

2 of one group flashes red (light for 1 second and off for 4 seconds), while the other group keeps the green light on. * When the fault is reported, the fault light of the

Protection

corresponding branch will stay red.

3 The status light of one of the two groups is off if it works normally. The general status light will flash green (light for 1 second and off

Normal

for 4 seconds) will stay on green light if an inverter is connected.

4 Green LED flashes once every 0.5 sec

5 Light off

Power off

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

Troubleshooting

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. 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:
