Based on my camper and current inteli-power PD9140A and 30amp breaker/10 awg wire, Im limited to the charging amperage and the right choice may be Progressive Dynamics PD69RR 45amp charging although need confirmation. Also, is the remote pendant separate?

Hey Steve, yes the Progressive Dynamics 9300 Series RV Converter Charger # PD69RR that you referenced would be the correct converter to replace your current PD9140A with. This is a 45 amp converter which is a little higher than what you have now but not high enough your current wiring would need to be replaced and also is compatible with lithium batteries like you need as well so it covers everything and will work great for you. Do you have solar on your Arctic Fox?
