Note: The Quick Installation Guide briefly describes required installation steps. If you have any questions, refer to the Installation
Manual for more detailed information.
Ensure that the installation location meets the following conditions:
The building is designed to withstand earthquakes
The location is far from the sea to avoid salt water and humidity, over 0.62 miles/997.79 meters
The floor is flat and level
There are no flammable or explosive materials, at a minimum of 3 ft//0.91 m
The ambience is shady and cool, away from heat and direct sunlight
The temperature and humidity remains at a constant level
There is minimal dust and dirt in area
There are no corrosive gases present, including ammonia and acid vapor
Where charging and discharging, the ambient temperature ranges from 32°F/0℃ to 113°F/45℃

In practice, the requirements of battery installation may be different due to enviroment and locations.
In that case, follow up the exact requirements of the local laws and standards.
- Fix the box to the bracket with M4 screws.
- Drill two holes with driller (ø 0.39 inch/10 mm)
- Depth: at least 3.15 in/80.00 mm
- Lock the joint between hanging board and wall bracket
with M5 screws. (Torque: 1.2-1.5 N·m)
The bracket needs to be removed from the box.

Note!
- If the batteries have not been used for more than 9
months, these batteries must be charged to at least
SOC 50 % each time.
- If one of the batteries is replaced, the SOC of the
battery after replacement shall be consistent with those
of batteries that have not been replaced, with the
maximum difference of between -5% and 5%.
- If users want to increase their battery system capacity,
please ensure that the SOC of the existing system
capacity is about 40%. The manufacture date of the new
battery shall not exceed 6 months; in case of exceeding
6 months, please charge the new battery to around
40%.
- Before installation, please make sure that the wall can
bear the weight of the batteries installed. If not, please
take the mode of floor installation.
The recommended installation distance between the
box and the battery group (incl.group 1 and group 2)
is 11.81-23.62 inches/300-600 mm, and the distance
between the modules is 9.84 inches/250.00 mm.
The SolaX battery module is rated at IP55 and thus can be installed outdoors as well as indoors.
However, if installed outdoors, the battery pack shall not be exposed to direct sunlight and moisture.
Note!
If the ambient temperature exceeds the operating range, the battery pack will stop running to protect
itself.
The optimal temperature range for operation is 59℉/15℃ to 86℉/30℃. Frequent exposure to harsh
temperatures may deteriorate its performance and lifetime.
Note!
For the first installation, the interval among manufacture dates of battery modules shall not exceed 3
months.

For Box:
Insert one end of the BMS communication cable w cable nut directly to the BMS port of the Inverter. Assemble the cable ithout
gland and tighten the cable cap.
For battery moudels:
Connect the RS485 II communication side to RS485 I . system on the right of the subsequent battery module on the left side
Note:There is a protection cover for the RS485 connector. Unscrew the cover and plug one end of the RS485 communication
cable to the RS485 connector. Tighten the plastic screw nut which is set on the cable with a rotation wrench.

Step 3.
Step 4.
Insert the stripped cable up to the stop (negative cable for DC plug (-)
and positive cable for DC socket (+) are live). Hold the housing on the
screw connection.
Press down the spring clamp until it clicks audibly into place (You
should be able to see the fine wire strands in the chamber)
Tighten the screw connection (Tightening torque: 2.0 ± 0.2 N·m)

In case of one group, please put
waterproof caps on the ports. See
figure above.
Note!
Please don't forget to put a waterproof cap on the port after
wiring is completed. See figure above.
Note!
Caution!
If DIP switch is 1, the number of batteries in these both
groups must be the same.
GND connection is mandatory!
Note!
To adjust the DIP switch, a small flat-head screwdriver
shall be prepared by users themselves.
Note!
After all battery modules are installed, please follow the following steps to
start the box:
1) Configure the DIP to the corresponding number according to the number
of battery module(s) that has(have) been installed;
2) Remove the cover board of the box;
3) Move the circuit breaker switch to “ON”;
4) Press the POWER button to start the box;
5) Reinstall the cover board to the box;
6) Turn on the inverter AC switch;
7) After starting the box, please confirm that the waterproof cap is closed
again.
