Preventative Maintenance

Periodic Maintenance
Xantrex Technology recommends that the following preventative maintenance
procedures be carried out on the PV225S.
Monthly Intervals or As Required
Perform the following preventative maintenance tasks on a monthly basis or as
required.
Aluminum Extrusion Heatsinks
❐
Inspect the aluminum extrusion heatsinks and external cooling fans for
accumulation of dirt and debris. Accumulation of dirt and debris on the
aluminum extrusion heatsinks and external cooling fans will decrease their
ability to transfer heat, which may cause the PV225S
to enter a fault state
based upon an over-temperature alarm. Remove and clean if debris is present.
Fan Operation
❐
Verify proper operation of the external cooling fans (B1 and B2) located
above the matrix aluminum extrusion heatsinks. These fans operate when the
K1 contactor is closed. If present, remove any debris from the fans.
Internal Circulation Fan
❐
Verify the internal circulation fan (B3) is operating whenever there is utility
power applied to the PV225S.
Inductor Enclosure Cooling Fans
❐
Verify that the inductor enclosure cooling fans (B4 and B5) operate whenever
the PV225S
is processing power. The airflow direction should be from the
outside, forcing air into the enclosure. If present, remove any debris from the
fans.
