Closely read the following requirements for inverter storage:
The following requirements should be met if the inverter is not put into use directly:

Do not unpack the inverter.

Store the inverter at -40°C to +70°C and under humidity of 0 to 100% RH
(non-condensing).

A maximum of four inverters can be stacked.

Periodic inspections are required during the storage. If any rodent bites are found,
replace the packing materials immediately.

If the inverter has been long-term stored, inspections and tests should be conducted by
qualified personnel before it is put into use.
