Can we adjust the CTEK?

Mine is always trickle charging the house battery. Right now I’m at 75% and it’s only doing 3A. I leave a fridge in the back and I’d like to be able to charge it up quickly when I start. It seems to charge the main battery but then gets lazy on the house. Is there a way to tell it to do its job because I need the battery capacity. Making the battery last longer doesn’t help me any if it can’t the job I need it to do now.

I am suspect of the smart alternator. It seem to under-perform unless you are in highly discharged state. I have a similar setup/needs to you, but put 200W solar on the roof.

Some questions and comments to try and understand your problem better.

1. How are you monitoring the auxiliary battery charge? If you are using the centre display, it only monitors the charging of themain battery. There is no monitoring the of the auxiliary battery charging..
2. Are you powering the fridge from the 12 V socket in the cargo Bay area or directly from the accessory battery? The cargo Bay socket draws power directly from the main battery.
3. Ineos designed the auxiliary battery system purely to start the car when the main battery is flat. All loads are drawn from the main starter battery. As such the auxiliary battery is not a true “ House” battery.

Subscribed - I bought the Iceco 250W battery for this purpose, it can run the fridge in Eco for over 24 hours and charges via the 110v socket in the rear when driving. I get about 14W charge in 30 minutes of driving.

Well, regardless, I’ve been running for 3hrs today and I’m at 81% with the alternator doing 2amps. It’s not wanting to charge past that for anything. I want it charging until the battery is full. I’m running my fridge off the 12v power outlet so it can make it through the night but if I get there and it quits charging at 75-80% I’m still not getting what I need.
