Centurion 3000

The centurion has a built in charger but it is very basic (not smart, not even average). I see time and time again these units failing, I would suggest you swap it out for a better quality unit or better still, buy a ctek and another 100amper and forget about converting 240v.

My honest opinion.

Both the Centurion and Setec power converters used in Jayco vans are pretty useless when it comes to battery charging. Neither produce a high enough output voltage to charge a battery in a timely manner. Jayco seem to blindly follow the American RV industry with power management systems. For a very good dissertation on these see this link Another interesting link is of an equipment supplier who has equipment to replace these inefficient power supplies see this link The problem with importing these units is that they are 110 V 60 Hz units.

You would be better off to replace your Centurion with a multi stage battery charger to charge your battery and run your lights off the battery.

Moo,

I won't waste your valuable time with a pointless and uninformed debate about the ability of the Centurion or Setec to charge a battery.

The Centurion will only provide a source 12V power for the van for lights, etc and is not designed as a switch mode battery charger in either 240V or 12V (from the car).

The Setec II, although a 4 stage battery charger, will only provide a managed charge in 240V mode. When you are drawing 12V from the car when travelling it simply becomes a fuse box and the 12V into the battery is the same as what is coming from the tow vehicle's alternator.

I suggest you get a good quality switch mode battery charger of at least 15A.
