• Control boards & DSPs firmware corruption signal loss
• Communication interfaces RS485/CAN/Ethernet faults
• Grounding systems insulation resistance failures EMI
• Firing angle control waveform distortion switching errors

• Conduct electrical testing thermal imaging firmware diagnostics and validate post-repair performance.
• Perform Root Cause Analysis (RCA) for recurring faults and document corrective actions.

Root Cause Analysis & OEM Engagement:

• Lead detailed RCAsfor inverter failures recurring faults and performance degradation.
• Document failure mechanisms contributing factors and corrective actions.
• Collaborate with OEMs for technical clarifications warranty claims and design feedback.
• SupportOEM change managementby evaluating technical compatibility and performance history.

Warranty LTSA & Insurance Support:

• Manage technical aspects ofwarranty claims including documentation failure evidence and OEM coordination.
• SupportLTSA (Long-Term Service Agreement)reviews and performance audits.
• Provide input forinsurance claimsrelated to inverter failures lightning damage or grid-related events.
• Recommendreplacement strategiesfor obsolete or underperforming inverter models.

Spare Parts Strategy & Procurement Support:

• Definespare parts maintenance strategiesbased on failure trends and criticality.
• Identify high-risk components and recommend stocking levels for IGBTs fans sensors and control boards.
• Supportspare procurement planningby evaluating vendor reliability compatibility and warranty coverage.

Site-Level Technical Support:

• Act as thefirst line of technical supportfor site teams during inverter breakdowns and performance anomalies.
• Provide on-site guidance during inverter commissioning upgrades and major maintenance campaigns.
• Analyze inverter logs fault codes grid interface parameters and SCADA data to support diagnostics.

Monitoring Platforms & Diagnostic Tools:
