Contents of this chapter
This chapter contains the preventive maintenance instructions of the inverter.
Maintenance intervals
If the inverter is installed in a suitable environment, it requires only minimum maintenance.
The tables list the routine maintenance intervals recommended by ABB.
The recommended maintenance intervals and component replacement are based on
specified operational and enviromental conditions. ABB recommends annual inverter
inspections to ensure the highest reliability and optimum performance. For more detailed
maintenance information, refer to the maintenance instructions, product manuals and the
ABB website: www.abb.com/solarinverters.
Inverter’s designed life time is 25 years. If the inverter is planned to be used longer than its
designed life time, additional maintenance and component replacements are
recommended. Contact ABB for more details.
After the product warranty expires, you can choose to not follow the recommended
preventive maintenance plan. The preventive maintenance plan is, however, a
prerequisite for ABB service contracts.
