4.7 Making network cable
11
The network cable between AOBOET battery and inverter should be made like that diagram. If
available, use a LAN cable tester to see whether the cable is faulty.

4.8 Storage
If the battery is not to be installed immediately, or removed from operation and needs to be
stored for a long period, please choose an appropriate location to store it. Instructions for
storage are:
• Do not stack more than four battery boxes.
• The temperature of battery stored recommended in the range of -20°C to 50°C. The
humidity should be less than 95 % RH.
• Do not expose to water
The battery box should be upright as shown in the following 󴐖gure and not stacked upside
down when storing the battery box.
If the battery needs to be stored over 3 months, the main breaker of battery suggests be
disconnecting. Otherwise, the battery would discharge at a minimum rate and capacity
degrades depended on storage time, the battery self-consumption less than 5w. And, if
the battery stored over 6 months, it is suggested to connect the battery with inverter and
commission the system.

5.3 Checks before installation
There are a few things to check before installing the battery to ensure that it has no defects.
Check item 1: Check the main breaker safety and stability;
Check item 2: Check the battery voltage.
WARNING If this checking process is executed for any reason after the battery is
fully installed, make sure that the inverter is turned off or break the
connection between battery and inverter while checking the battery.
CAUTION There is a hook on the cover plate back, please following the indication
which stuck on the cover.

the main breaker is in the OFF position.
4. Make sure the main breaker behind the
OFF position until it cannot go any further
and then push it to the ON position. If the
breaker moves to any other positions by itself,
do not use the battery. Contact AOBOET hot
line or your distributor. 15

5. Press and hold the panel button
for about 4 seconds and then release
it after the four LED lights on, measure
the voltage at the terminal block with
a voltmeter. If the voltage is lower than
43 V, do not use the battery and contact
AOBOET hot line or your distributor.
6. Switch the main breaker OFF,
and then measure the voltage at the
terminal block with a voltmeter again.
If the voltage is higher than 0V, do not
use the battery and contact AOBOET
hot line or your distributor.
7. Replace the top cover and tighten
the screws to a torque of 0.25 N·m.
5.3 Installing the battery
To prevent the battery from moving, make sure the battery 󴐖xed to a wall.
Note The symbol located on the back cover plate, and the earth wire
between battery and inverter is not compulsive but recommended.
Note If the battery is installed above the 󴐗oor or on a platform, make sure
that the wall or platform is capable of supporting the battery’s weight.
1. Determine bracket mounting
place to be 󴐖xed using the bracket.
2. Drill holes in the wall for the M6
(0.25 in) screw anchors, and the hole
depth should be at least 50 mm.
