Heart Interface Freedom 20D Battery Charger

The Heart Interface Freedom 20D is a dual‑function DC‑to‑AC inverter/charger designed for RV and marine use, accepting 12 V DC input and delivering up to 200 A AC output with automatic battery‑charging stages. Common failure modes include blown or tripped fuses, degraded rectifier diodes, failed MOSFET modules, and worn thermal protection relays; users often report sudden shutdowns or lack of charging while on shore power. First‑check diagnostics: verify the 12 V DC supply voltage and fuse integrity, inspect the inverter’s internal PCB for burnt components or loose connections, and review any displayed error codes or LED status indicators before proceeding to component replacement.[oss-gpt-20b]
