The AIMS PWRINV8KW12V is an 8000 W modified‑sine DC‑to‑AC inverter that accepts a 12 VDC input and delivers up to 16 kW surge output on four NEMA‑5‑15R outlets. Common failure modes include overheating of the internal MOSFET array (often triggered by high ambient temperature or inadequate ventilation), blown main fuses due to input voltage spikes, and degradation of the power‑factor correction capacitor bank causing output waveform distortion or over‑current protection trips. First‑check diagnostics should verify that the 12 V supply is within ±5 % of rated voltage and free of ripple, inspect the inlet fuse and any resettable PTCs for continuity, and examine the inverter’s temperature indicator LEDs or internal thermistor readings for signs of thermal overload.[oss-gpt-20b]
