Understanding the Risks: Why PV Inverters Demand Attention

Photovoltaic inverters, the heart of solar energy systems, convert DC power from solar panels into usable AC electricity. However, like any complex electrical equipment, they carry inherent risks that require careful analysis. Did you know that 38% of solar system failures originate from inverter-related issues? Let's explore the critical danger points and how to mitigate them.

Top 5 Danger Points in PV Inverters

• Arc Faults: Responsible for 23% of fire incidents in solar installations
• Overheating Components: Can reduce efficiency by up to 15% and cause thermal runaway
• Insulation Degradation: Moisture ingress accelerates corrosion in outdoor installations
• Grid Synchronization Failures: Causes 12% of system shutdowns in unstable grid regions
• Capacitor Aging: Electrolyte leakage risks increase after 5-7 years of operation
