Xantrex Freedom 458 Inverter

The Xantrex Freedom 458 is a 2000‑W filtered modified sine‑wave inverter/charger designed for RV and marine use, featuring temperature‑controlled multi‑stage charging and automatic shutdown protection. Common failure points on this model include the DC input fuse or relay, the internal power MOSFETs (often showing burn marks), and the battery monitoring circuitry that can misread voltage under load. First‑check steps: verify 12 V DC supply continuity and correct polarity; inspect the inverter’s output transformer and MOSFETs for overheating or damage; review the LED status sequence and any error codes displayed on the unit’s front panel.[oss-gpt-20b] Post Comment
