Note: The Quick Installation Guide briefly describes required installation steps. If you have any questions,
refer to the
Installation
Manual for more detailed information.
NOTE!
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
The floor is flat and level
There are no flammable or explosive materials, at a minimum of 3ft
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 to 113°F
The Solax battery module is rated at IP55 and thus can be installed outdoors as well as indoors. However, if
installed outdoors, do not allow the battery pack to be exposed to direct sunlight and moisture.

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!
If the ambient temperature exceeds the operating range, the battery pack will stop operating to protect itself.
The optimal temperature range for operation is 15° to 30° Frequent exposure to harsh temperatures may C C.
deteriorate the performance and lifetime of the battery module.
NOTE!
- Match the box with the bracket.
M4 screws. (torque:(1.5-2)Nm)
- Drill two holes with driller
- Depth: at least 3.15in
- Lock the joint between hanging board and wall bracket
with M5 screws. (torque:(2.5-3.5)Nm)
The bracket needs to be removed from the box.

NOTE!
When installing the battery for the first time, the manufacturing date between battery modules
should not exceed 3 months.
-If the battery is not used for more than 9 months, the battery must be charged to at least
SOC 50 % each time.
-If the battery is replaced , the SOC between the batteries used should be as consistent as
possibe, with a maxium difference of ±5 %.
-If you want to expand your battery system capacity, please make sure your existing system
capacity's SOC is about 40%. The expansion battery is required to be manufactured within 6
months; If more than 6 months, recharge the battery module to about 40%.

NOTE!
If all the battery modules are installed, follow these steps to put it in
operation
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 theON position
4) Press the POWER button to turn on the box
5) Re-install the cover board to thebox
6) Turn on the inverter AC switch
Configuration activated by inverter::
0- Matching a single battery group(group 1 or group2)
