5 Storage
If the Sunny Central is to be stored prior to installation, note the following:

Penetrating moisture can damage the Sunny Central
If the Sunny Central is not stored properly, moisture can penetrate the enclosure and cause damage to electronic
components.
• Store the Sunny Central in a closed state.
• Store the Sunny Central in a dry and covered location.
• The temperature at the storage location must be between -25°C and +70°C.
/05*$&
An uneven foundation can damage the frame construction of the Sunny Central
Storing the inverter on an unsuitable foundation could damage the frame construction. Dust and moisture can penetrate
the inverter and damage electronic components.
• The foundation must be suitable for the weight of the Sunny Central (1,800 kg).
• The unevenness of the foundation must be less than 0.25%.
Storage in high humidity
If the Sunny Central is connected to the external supply voltage and the circuit breaker of the supply voltage is
switched on during storage, the heating system will activate automatically when humidity is high (see Section 12.3.6
"Connecting the External Supply Voltage", page 64).
Desiccant bag in the inverter cabinet
The desiccant bag in the inverter cabinet protects the electronic components from moisture. The desiccant bag must
be replaced by a new desiccant bag one day before commissioning.
