4.4 Storage of Inverter
Where the inverter may not be installed immediately or inverter needs to be
stored under certain condition, store the unit as the following indications:
The unit must be packed into original carton and desiccant must be put
inside. If the original packaging is not available, an equivalent carton which is
able to support the unit weight and size can be used.
The packing should be sealed by adhesive tape.
The unit must be stored in a clean and dry place to protect against dust and
moisture.
The storage temperature should be always between -30
℃
and 85
℃
. And
the storage relative humidity can reach 100%.
The recommended number of stack layers is not more than 4.
It is very important to keep the packing away from chemicals. Otherwise it
will lead to corrosion.
During the storage time, periodically check any visible damage by rats and
other rodents. Replace the packaging if necessary.
The packaging should be kept upright.
After long term storage, local installer or service dept. of Sungrow should
perform a comprehensive test before connecting the inverter into PV power
system.
