13.4 Keeping the inverter in storage
If you store the inverter temporarily or for a long time after purchase, follow the instructions below.
1. Storage
location
Store the inverter indoors. Avoid to be exposed to direct sunlight, corrosive, explosive or flammable gases,
salt, oil mist, dust, metal powder, vapor or condensation.
Storage temperature and Relative humidity are shown in the table below.
2. Periodical
check
If no power is supplied to the inverter for a long time, the performance of its main circuit smoothing
aluminum electrolytic capacitor declines.
When leaving the inverter unused for a long time, energize it for an hour or more each without load in
accordance with the table below, to recover the performance of the electrolytic capacitor.
Then check the function of the inverter.

How to recover the performance
of the electrolytic capacitor
Short-term Storage
(within one month such as
during transportation)
-25 to 70
within 95%
Supplying power without load
is not required.
Long-term Storage
(exceeding one month)
-10 to 40
Within 90%
Supply power once
every two years for an hour or more.
