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:
y
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.
y
The packing should be sealed by adhesive tape.
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 -30°C and 85°C. And the
storage relative humidity should be always between 0 and 100%.
y
It is very important to keep the packing away from chemicals. Otherwise it will
lead to corrosion.
y
During the storage time, periodically check any visible damage by rats and other
rodents. Replace the packaging if necessary.
y
The packaging should be kept upright.
y
If there is more than one inverter to be stored, the maximum layers for original
carton is three.
y
After long term storage, local installer or service dept. of Sungrow should
perform a comprehensive test before connecting the inverter into PV power
system.
