Solar Inverter Troubleshooting in South Florida

When your inverter fails, your entire system stops producing power. Fix My Solar diagnoses all inverter types across all major brands — providing honest repair vs. replacement assessments backed by real electrical testing.

Inverter Problems: The #1 Solar Repair Call in South Florida

Inverter failure is our most common repair call. String inverters from 2012-2018 are hitting end of their 10-15 year service life. Even microinverter systems experience unit failures that silently cut output by 10-25% per failed unit without obvious alerts.

Inverter problems aren’t always obvious. A full string inverter failure shuts everything down — impossible to miss. But a single failed Enphase microinverter or SolarEdge string issue reduces output while the system appears operational. Without panel-level diagnostics, these partial failures go undetected for months.

Our troubleshooting includes full system diagnostics: fault code reading, monitoring data history analysis, DC array testing, AC output measurement, and thermal performance assessment. You get a written report explaining exactly what’s wrong and cost to fix.

Frequently Asked Questions

Fault codes vary by manufacturer. Common codes indicate grid voltage issues, DC arc faults, ground faults, temperature shutdowns, and communication errors. We decode all major manufacturer codes.
Many faults are repairable — capacitors, communication boards, IGBT modules, cooling fans are all serviceable. We always assess repair viability before recommending replacement.
Could be inverter MPPT issues, partial string failures, or panel-related. Our diagnostic process identifies the exact source.
Diagnostic visit: 1.5-2.5 hours. Simple repairs may be completed same-day. Component replacements typically completed within 3-5 business days.
