Ensure that the installation location meets the following conditions:
The building is designed to withstand earthquakes
Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ
The location is far from the sea to avoid salt water and humidity, over 0.62 miles/997.79 meters
Ÿ
The floor is flat and level
Ÿ
There are no flammable or explosive materials, at a minimum of 3 ft/ /0.91 m
Ÿ
The ambience is shady and cool, away from heat and direct sunlight
Ÿ
Ÿ
The temperature and humidity remains at a constant level
There is minimal dust and dirt in area
Ÿ
Ÿ
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℃
Ÿ
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.
Note!
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.

- Drill two holes with driller (ø 0.39 inch/10 mm)
- Depth: at least 3.15 in/80.00 mm
- Fix the box to the bracket with M4 screws.
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.
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.
