Tripp-Lite PV-550 AC/DC Inverter Repair Service

Professional diagnostic and board-level repair service for this Tripp-Lite PV-550 AC/DC Inverter.

The Tripp‑Lite PV‑550 is a 550 W DC‑to‑AC power inverter that steps 12 V battery input to 115 VAC output, commonly used for mobile or emergency backup systems. Known failure modes in this class include capacitor degradation, MOSFET burnout from over‑current or overheating, and transformer winding insulation breakdown; the unit may also exhibit output voltage ripple or shutdown due to protection circuitry tripping. First‑check diagnostics: verify 12 V input voltage and polarity with a multimeter, inspect for blown fuses or damaged heat sinks, and examine the output waveform for distortion or low RMS voltage before proceeding to component replacement.
