4.4.4 Battery Installation Steps
It is recommended that the space between battery packs is more than
300mm.
Steps (for SE-BAT-MA H 5.8 or SE-BAT-SL H 5.8):
Make sure the wall is strong enough to withstand the weight of battery packs.
Step 1: x the wall brac et (H or G1) on the wall
ŸUse the wall bracket as a template to mark the position of the 5 holes
ŸDrill holes with φ 0.39 in/10 mm drill, make sure the holes are deep enough (at least
80mm) for installing and tightening the expansion bolts (J or I1)
ŸInstall the expansion bolts in the wall, and screw the bracket by using the
wrench.
Step 2: Match the battery with the wall bracket
ŸTransport the battery to the wall bracket
ŸHang the battery over the wall bracket, move the battery close to it, and
match it on the wall bracket
Step3: Lock the joint between hanging board and wall bracket with M5
combinationscrew (I or H1).
Note: 1 Keep the distance from installation point to the oor less than 259.59 in/650.00 mm..

4. Installation 4. Installation
For 2~3 battery modules:
The power cable between battery modules (A1) is different from the one that
between BMS and battery module (C). The other end of the power cable is black,
and this color is connected to YPLG (Ⅴ’), which is on the right side of the battery
module.
1. Connect YPLUG (Ⅴ’)on the right side of battery module to XPLUG (Ⅰ’) on the
left side of the second battery module. The rest battery modules are connected
in the same way. The following gue shows that four battery modules are
connected.
2. Before connecting the cables to XPLUG (Ⅰ’) on the left side of follow-up
battery module, lock the terminal box_medium_right(I1) on the right side of
previous battery module with M4 screws(H1), and get the cables through the
conduits which length is 7.87~9.45 in/200.00~240.00 mm, then lock the terminal
box cover (K1) with M4 screws.
3. Lock the terminal box_medium_left(J1) on the left side of follow-up battery
module, and keep the terminal box cover (K1) unlocked until the cables are
correctly connected to the YPLUG.

3. Pass the other end of the charging cable through the inverter's pipe.Insert the
trip head of each wire into the hole.
NOTE!
1. When connecting the cable to SE-BAT-MA H 5.8, t the wo connectors together
until the connection audibly locks into place.
2. Check to make sure the connection is securely locked.
3. Don't shake both ends of the cable at the joint once the connection is locked.

This step is going to connect power lines between Inverter and SE-BAT system.
The default length of power lines are 2 meters, so customers can6.56 feet/
propriately cut the cable accroding to the actual installation environment. As a
result, eachpower line has one terminal block when leaving the factory, and
customers need to connect the other end of terminal block by themselves.
1. Connect the positive cable (+)(A) and negative cable (-)(B) through the accessory

4.5.4 Connecting CAN Communication Cable
It is required for the BMS to communicate with the inverter for proper operation.
2. Connect the CAN communication cable to
the CAN connector (II) which is marked in red.
Insert the other end of the CAN communication
cable to the CAN connector. Assemble the cable
gland and screw the cable nut.

CAUTION!
One SE-BAT system is allowed to install one SE-BAT-MA H 5.8 plus at most
three battery packs. Connecting more than three battery packs will blow
the fuse, and the battery pack will be damaged. Please make sure the
number of battery packs meets the requirement.

The black-start function is only used in the off-grid environment and there is no
other power supply.
Note: if the battery is started in black-start mode, although there is no BMS
communication, the port still has high voltage and there is a risk of electric
shock!
After the black-start mode is started, if the BMS communication has still not been
built within 3 minutes , the black start fails.

NOTE!
When powering on the BMS, the system will start self-testing. If the
buzzer bips, it means DIP conguration fault or communication failue
occurs. If the buzzer bips, please check if the number of battery packs is
corresponding to the DIP conguration, and also check if the RS485
communication calbes are correctly connected. After these two
situation checked OK, press the POWER button to power on, and press
the POWER button again 10s later. In addition: The buzzer will only
alarm on the corresponding fault during the power-on self-test. After
the self-test is completed, it won't bip again even if the same fault
occurs.
NOTE!
Frequently pressing the POWER button may cause the system error.
Please make sure at least 10 seconds is needed when you are going to
press the POWER button from the last pressing operation.

5.3 Status Indicators
The LED indicators on the front panel of the battery pack are showing the
operating status.
5.3.1 BMS
The capacity indicators show the SOC:
ŸWhen the battery pack is neither charging nor discharging, the indicator
lights off.
ŸWhen the battery pack is charging, part of the Blue LED is ashing with the
frequency of light on for 0.5s, light off for 0.5s, and part of the Blue LED keeps
light on. Take SOC 60% for instance, in charging state:
1. The rst wo Blue LED indicators keeps on
2. The third Blue LED indicator ashes once evey 1s
ŸWhen the battery pack is discharging, the Blue LED is ashing with the
frequency of light on for 1s, and light off for 4s. Take SOC 60% for instance, in
discharging state:
1. The rst three blue LED indicators ash once every 5s
