Like others, I am experiencing converter problems, specifically tripping the 20 amp breaker. Last year, our converter fan quit, causing the converter to over heat and die a premature death. I replaced it with an Iota DLS 55 amp RV Power Converter & Battery Charger (IQ4), and the problem at first seemed to go away. This year, it started tripping the circuit breaker, so I replaced the breaker, but it still trips occasionally. I think I know why: specs on the converter state it can draw up to 20 amps on what the manufacturer calls "Max inrush current". I am guessing this is when the battery is discharged, and the converter is suddenly called on for max recharging current.
I'm not aware of any 'slow blow' house type circuit breakers, so I'm considering sticking in a 25 amp breaker. Has anyone else tried this?
