Converter/Panel Recommendation for 1972 Airstream Argosy
Updated 08/07/2025 | Published 07/12/2025
Question:
I’m resetting the electrical system and a 1972 Airstream Argosy. It has a 30 amp AC/DC service with 2 15amp ac breakers and a 4 20amp dc fuses. I’m getting 2 100ah Lifepo4 batteries and the solar side will be Victron. What converter would you suggest? I want to charge while connected to shore power and have automatic switching between dc sources, converter when connected to shore power and battery when not. Thanks in advance. John

Hey John, the most similar panel we have to what you have now is the Progressive Dynamics Mini Converter part # PD4045KA which is rated for 45 amps and is compatible with your lithium batteries.
On the DC power source question there isn't a transfer switch available for that but since it's a DC power source there's no reason you couldn't have both active at same time as unlike AC power having multiple DC power sources connected does not cause issues.
