⚡ Resuscito un Inverter distrutto: Driver e stadio finale 💥

This video documents the repair of a photovoltaic system inverter with a 24VDC input and 230VAC output, a nominal power of 3500W and a peak power of 7000W, and a pure sine wave output. The fault involved the output stage and the control drivers. After analyzing the problem, I demonstrate the replacement of the damaged components and the final testing phase to verify proper operation.
