Configuration of control boards of the inverter (named DUT in the following).
Verification that the wiring and cabling of the DUT have been executed correctly after the
Production stage.
FW flash onto the microprocessor-based PCBs, through dedicated SW.
Calibration of all the electrical measurements acquired by the DUT (voltage, current and
temperature sensors) and set-up of relevant SW parameters.
Verification that the operation of the DUT be consistent with the technical specification of
the product (voltage and current distortion, efficiency, isolation strength within specified
limits).
Failure analysis and in-factory repairing of failed inverters coming back from field.
Repairing of defective PCBs.
Technical phone troubleshooting on the inverter with installers or final customers.
Writing of brief procedures for know-how dissemination about testing and instruments
operation to newcomers.
PROFILE AND EDUCATION
The ideal candidate has to have at least an high school technical degree in electronics or electrical
