4.4 Storage of Inverter
If you do not install the inverter immediately, you should choose an appropriate
location to store it.
y
The unit must be stored in original packaging and the desiccant must be left in
the packaging.
y
The unit must be stored in a clean and dry place to protect against dust and
moisture.
y
The storage temperature should be always between -25 °C and +60 °C. And the
storage relative humidity should be always 0 and 95%.
y
It is very important to keep the packaging away from chemicals. Otherwise it will
lead to corrosion.
y
During the storage time, check periodically for visible damages by rats. Replace
the packaging if necessary.
y
If there is more than one inverter to be stored, the maximum layers for original
paper packaging are five.
After long-term storage or decommissioning, local installer or Service
Dept. of Sungrow should perform a comprehensive test before
connecting the inverter into PV power system.
