3.3 Installation Requirements
3.3.1 Environment Requirements
•
Install the B500 battery in a well-ventilated and spacious area to ensure good heat
dissipation.
• The B500 battery has an IP65 rating and can be installed indoors and outdoors.
Please note that if you place the system outside the house, use a cabinet to protect
it from direct sunlight, as this may cause a degradation in system performance.
• The enclosure and heat sink are very hot while the inverter is working, therefore do
NOT install the inverter in places where you might touch inadvertently.
• Keep the B500 battery away from flammable liquids, gases, or explosive materials.
• Keep away from children and pets.
• Do not install the B500 battery outdoors in salt-affected areas, as the accumulation
of salt may corrode the system. Salt-affected areas are those within 500 meters
from the coast or susceptible to sea breezes. Salt accumulation is influenced by
seawater, sea breeze, precipitation, air humidity, topography and forest cover of
adjacent sea areas.
• Do not install the system in low-lying areas where water tends to accumulate.
Otherwise, water may leak into the equipment and result in system failure.
• Ambient temperature range: -20℃～50℃
• Relative humidity: 5%～95% (non-condensing)
• Maximum height: 2000m.
Attention
Danger
If the battery pack is dropped, violently impacted or tilted during
installation, internal damage may occur. So do not use such battery
packs to avoid safety risks such as battery leakage and electric shock.
JUST POWER ON 27
3.3.2 Location Requirements
•
The B500 battery should be installed ona firm, flat, level base.
• Do not install the system on flammable materials.

Step 1: Place the base on the ground and adjust the height of leveling feet so that
the base stands stably on the ground. Don’t forget to tighten the nuts to secure the
leveling feet.
Step 2: Mark the drilling positions with tape and marker. Drill holes with an electric
drill and insert M8 expansion bolts.
Note: If you are working with a wooden wall, simply mark the positions and use M8
self-tapping screws to secure the unit directly onto the wall.
Step 3: Move the B500 battery pack to the base. Two people are required to transport
the B500. Align the bumps on the battery with the notches on the base to secure
the battery in place.

Step 1：Connect two B500 battery packs via the battery expansion cables - black
cable for negative terminals, red for positive terminals. See “①” “②” of Figure 5-9-1
and 5-9-2.
• Secure the black protection cover with M4 screws. See Figure 5-9-3.
• Connect the other end of the cable to the B500 BAT- terminal.
• Repeat to connect the red battery power cable. See Figure 5-9-4.
Recommended torque: Less than 6Nm for M8 screws, 1.2Nm for M4 screws.
Step 2：Check that the cables are properly connected.

Step1：
To achieve communication between two B500 battery packs, a communication
cable is required. Plug one end of the cable to the B500 Link-in port, and the other
to the upper B500’s Link-out port. See Figure 5-10 “①”.

4.1 Preliminary Check
Check the followings before first use.
• Confirm that all components of the system are installed according to specific
requirements.
• Make sure the PV+/PV- and BAT+/BAT- cables are connected with correct polarity
and proper voltage.
• Switch off all AC and DC circuit breakers.
• Circuit breakers should be selected according to the requirements of this manual
and local regulations.
• Make sure grid and load cables are held firmly in place.
• All safety signs and warning labels shall be firmly attached and clearly visible when
needed.
4. System Check
4.2 Commissioning/Startup

8. FAQs (Frequently Asked Questions)
What should I do if the SoC readings are inaccurate?
If you notice significant momentary fluctuations in the SoC, try performing two
complete charge and discharge cycles on your inverter. This will help recalibrate
the system and restore accurate SoC readings.
