Storing the inverter
•
To prevent damage to the inverter, keep it in the protective packaging.
•
Store the inverter in the upright position. Do not put it on its side or back.
•
To prevent condensation in the inverter, store it indoors in a dry (heated) warehouse.
•
If the inverter is removed from the protective packaging and condensation is possible
in the storage area:
•
Supply power to the internal heaters to keep the inside temperature of the inverter
above the outside temperature.
•
If power is not available, add humidity desiccant bags inside the inverter. Use
desiccant bags, if the unit is stored for more than two weeks without electric
heaters. Use 200 grams of desiccant per week. For example, for four weeks of
storage, use 800 g of desiccant bags. Replace the bags with fresh bags every four
weeks and do not open the doors unnecessarily during the storage period.
Examples of suitable container desiccants: Xdry desiccants “H model” or Clariant
“Container Dri®II-Pole”. When it leaves the factory, the inverter has desiccant
bags inside.
•
The air inlets and outlets of the inverter are sealed. If it is not required, do not open or
remove any protective packaging.
•
If the inverter is stored outside for an extended period, this can cause damage to the
protective packaging.
•
Make sure that the ground under the inverter is solid, flat, dry and vegetation-free.
Make sure that the ground gives support to the inverter evenly from below. There must
be no twisting or stress. Do not put the inverter onto bare ground because this can
lead to paint damage and corrosion.
•
Keep the inverter on the wooden support beams.
