Why Bus Overvoltage Matters in PV Systems

Imagine your PV system as a highway - the inverter bus acts like a critical interchange where energy flows converge. When photovoltaic inverter bus overvoltage occurs, it's like a traffic jam during rush hour, potentially damaging equipment and reducing energy harvest. This guide explores practical solutions while addressing what solar technicians and project managers really care about: reliability and ROI.

Common Culprits Behind Overvoltage Events

• Sudden cloud transitions causing irradiance spikes
• Grid impedance mismatches (especially in weak grids)
• Aging capacitors in DC-link circuits
• Faulty maximum power point tracking (MPPT) algorithms
