6.4 Inspection and Replacement of the Damageable Part
Filter Capacitor
The pulsating current of the main circuit will influence the performance of the aluminum
electrolytic filter capacitor depend on the ambient temperature and the application
condition. The electrolytic capacitor of the sunverter should be replaced after 10 years,
however, if the filter capacitor's electrolyte is leaking or the safety valve bursting out of
the capacitor main body is expanding it should be replaced immediately.
When the lter capacitor is powered, the voltage should be
increased through a DC supply and power on time should not
be less than 5 hours.
NOTE
Cooling Fan
The Sunverter has a cooling fan inside. Replace the fan if it makes abnormal noise or
vibrations.
6.5 Storage
If the product is to be stored, the following should be noted:
Avoid high temperature or humidity or where there is vibration and metal dust,
_
ensure proper ventilation at all times.
Filter capacitor performance declines with long–time disuse. It is necessary to
_
energize it once every 2 years to restore performance. Inspect the inverter function
at the same time.
