multiple systems, up to six in parallel. In parallel, the positive and negative poles of the power
lines are connected in turn. The communication line is connected from the “Link Port 1” of the
first battery (the battery connected to the load or inverter) to the “Link Port 0” of the second
system, and the “Link Port 1” of the second system is connected to the second system. The
"Link Port 0" of the three systems, and so on, can connect up to 6 units. The panel dial switch
does not need to be dialed. See the figure below for details:
Figure 11. electrical installation diagram
Directly connect the battery of the load or inverter, draw the communication line from the CAN
communication port to the communication port of the load or inverter, and connect the
positive and negative cables to the positive and negative ports of the load or inverter
respectively.
5 Operating
5.1 Boot Up
Before powering on, make sure that the communication and positive and negative cables are
correctly connected, and there are no foreign objects around the battery. Boot steps:
•Press the system power button;
•Long press the red soft start button for 3 seconds. All panel lights flash once;
•The green running indicator flashes every 2 seconds, indicating that the system is booted
normally;
•If multiple units are used in parallel, first press all the power buttons of all batteries, and then
press and hold the red soft start button of any battery for 3 seconds, all batteries are
automatically turned on.
5.2 Shutdown

Worldwide Energy and Manufacturing USA Co., Limited
12
Before disconnecting the cable from the battery, make sure the battery is turned off.
Shutdown steps：
•Press and hold the red soft start button for 3 seconds, all the indicators on the panel will be
on;
•Release the red button and the indicator light goes out;
•Turn off the power button again;
•If multiple units are used in parallel, after the battery connected to the load or inverter is shut
down, the other batteries will shut down automatically. There is no need to turn on one by one,
but the power button still needs to be turned off manually.
6 Maintenance
•Battery maintenance must be performed by professionals;
•If the battery is stored continuously for more than three months, it must be fully charged
once;
•Every three months, check whether the connections of battery communication and power
cables are loose.
7 Troubleshooting
Troubleshooting can only be performed by professionals. Before checking for faults, you must
check whether all cable connections and circuit breakers are in the correct state.

failure
Check whether the communication line is
loose, and check whether the BMS
communication protocol matches the load or
inverter.
2 Unable to boot Use a charging device to charge the battery. If
it still cannot be turned on, please contact for
maintenance.
3 SOC abnormal Turn off the soft start switch when shutting
down, and then turn off the power switch
after 1 second.
