Inverter Fault Downtime Losses

2 verified sources

Definition

Inverter earth faults trigger automatic shutdown per Australian standards, requiring manual diagnosis via voltage measurements and visual inspections. Delays in scheduling replacements lead to extended downtime and zero generation.

Key Findings

  • Financial Impact: AUD 100-500+ per day lost revenue for 5-10kW residential systems (based on typical 20kWh/day output at AUD 0.25-0.50/kWh retail offset)
  • Frequency: Common in PV systems; string faults and outages detected via monitoring case studies
  • Root Cause: Manual fault localization process (voltage-to-ground measurements, visual inspections) and replacement scheduling delays

Why This Matters

The Pitch: Solar operators in Australia 🇦🇺 lose hundreds of AUD per incident in foregone revenue from inverter downtime. Automation of fault detection and scheduling eliminates this capacity loss.

Affected Stakeholders

Solar installers, System owners, Maintenance technicians

Evidence Sources:

Related Business Risks

Underperformance Compensation Claims

AUD 200-1,000+ per incident in lost customer revenue offset and compensation (e.g., 'hundreds of dollars' saved via early fix)

Manual Fault Diagnosis Labor Costs

AUD 500-1,500 per fault (4-8 hours technician labor at AUD 120-180/hour incl. travel)

Non-Compliance Penalties & System Disconnection Risk

AUD 10,000–50,000 per installation (estimated statutory penalties); potential loss of entire project revenue if disconnected post-installation.

Lost Government Rebates & Feed-in Tariff Income

AUD 3,000–8,000 per residential installation (typical STC value + 10 years feed-in tariff foregone)

Rectification & Rework Costs Due to Inspection Failures

AUD 2,000–6,000 per failed inspection (electrician callout, parts, re-certification labor)

Grid Approval Delays & Installation Queue Bottlenecks

40–50 hours labor per project (4–8 week calendar delay × AUD 50–100/hour fully loaded cost); lost installation throughput = AUD 5,000–15,000 revenue delay per installer per month
