Maintenance Intervals
The maintenance intervals must be adhered to in order to warrant a safe and
precise operation. The requirement for these maintenance intervals is an assembly
at an average annual temperature of +20 °C, whereby the maximum cooling air
must be within the +50 °C to -15 °C range.
In principle, customers choose between two types of maintenance intervals:
•
Maintenance interval determined by the environmental degree of pollution or
•
Maintenance interval determined by facility’s operating time.
•
Xantrex recommends at a minimum that the Maintenance Interval
be annually.
Periodic Maintenance
Xantrex Technology, Inc. recommends that the following preventative
maintenance procedures be carried out on the GT100.
Monthly Intervals or As Required
Perform the following preventative maintenance tasks on a monthly basis or as
required.
Intake Air Duct
Inspect the intake air duct and cooling fan for accumulation of dirt and debris.
Accumulation of dirt and debris within the duct and matrix cooling fan will
decrease their ability to move air and thus transfer heat away from the IGBT
matrix heatsink, which may cause the GT100 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 cooling fan, located at the rear of the enclosure.
This fan is dependent upon GT100 power level operation and temperature of the
matrix heatsink. The fan will operate if the matrix temperature reaches at least
30°C and the "INV kW" is at least 30 kW. If present, remove any debris from
the fan.
Inductor Enclosure
Cooling Fan
Verify the inductor cooling fan operates whenever the GT100 is processing power.
The airflow can de detected from the outside at the upper vent and lower grill.
Six Month Intervals
Perform the following preventative maintenance tasks on a six-month basis or
as required.
Enclosure Seals
Inspect the enclosure door seals. If damaged, replace with equivalent closed cell
foam gasket. Call your Xantrex Technology distributor for factory replacements
or specifications.
Electrical
Connections
Inspect the condition of all wiring within and interfacing to the GT100. Inspect all
compression-type cable terminations and box-type connections within the AC and
DC Interface, and the Main Inverter Enclosure for damage caused from high
temperature. Also check these terminations and connections for signs of
corrosion. If any cabling or wiring within and interfacing to the PV GT100 are
