Storage

4.1 Inverter Storage

The following requirements should be met if the inverter is not put into use directly:
1.
Do not unpack the inverter.
2.
Keep the storage temperature at -40~70°C and the humidity at 5%~95% RH.
3.
The inverter should be stored in a clean and dry place and be protected from dust
Grid
and water vapor corrosion.
4.
Up to six inverters can be stacked. To avoid personal injury or device damage, please
stack inverters with caution to prevent them from falling over.
5.
During the storage period, check the inverter periodically. (It is recommended that
the check is performed every three months.) Replace the packing materials that are
damaged by insects or rodents in a timely manner.
6. If the inverters have been stored for more than two years, it must be checked
and tested by professionals before being put into use.

4.2 Battery Storage

The following requirements should be met if the battery pack is not put into use directly:
1. Place batteries according to the signs on the packing case during storage. Do not put
batteries upside down or sidelong.
2.
Stack battery packing cases by complying with the stacking requirements on the
external package.
3. Store the battery pack out of reach of children and animals.
4. Store the battery pack where it should be minimal dust and dirt in the area.
5.
Handle batteries with caution to avoid damage.
6.
The storage environment requirements are as follows:
– Ambient temperature: -10~55°C; recommended storage temperature: 15~30°C
– Relative humidity: 15%~ 85%
– Place batteries in a dry and clean place with proper ventilation.
– Place batteries in a place that is away from corrosive organic solvents and gases.
– Keep batteries away from direct sunlight.
– Keep batteries at least 2 meters away from heat sources.
7. The batteries in storage must be disconnected from external devices. The indicators (if
any) on the batteries should be off.
8. Batteries should be delivered based on the "first in, first out" rule.
9.
The warehouse keeper should collect battery storage information every month and
periodically report the battery inventory information to the planning department. The
batteries that have been stored for nearly 6 months should be recharged timely.
10. If a lithium battery is stored for a long time, capacity loss may occur. If a lithium
battery is stored for 12 months in the recommended storage temperature, the
irreversible capacity loss rate is 3%~10%. It is recommended that batteries not be
stored for a long period. If the batteries need to be stored for more than 6 months, it
is recommended to recharge the batteries to 65～75% of the SOC. For example, they
can be recharged every 6 months at least, and must be recharged to at least 50% of
the SOC.
