I have a small solar setup (MPPT 100/30, Smart Shunt, 12v AGM batteries). There is some voltage-sensitive equipment that really wants 13.8v at night, but will tolerate down to 12v.  
Am looking for a buck/boost converter to give me a regulated 13.8v, current draw typically 5-10A, probably 20A maximum continuous. Ideally with no additional batteries.

Is there an Orion that can be used just as a converter, not a charger? or something else?

Any suggestion welcome. Thanks in advance!

On the Orion range there are chargers and converters. Isolated and non isolated.  
What voltage is your main system? 12v?

Sounds like you want something that runs more as a power supply.

Which the Orion XS is able to do at a voltage specified and the orion 12/12/30 (in keeping with your max demand of 20A)

Yes, 12V. Yes, more like a power supply.

I wish Victron had ONE comparison chart for ALL models. Otherwise I have to download the data sheets for each one and try to figure it out.  
The first units I looked at seemed like they were 12.2V output only.

The Orion Tr-Smart 12 | 12-30 isolated says 12.2, but I see 10-15V adjustable. This could work nicely. Thanks for the recommendation - otherwise I would spend hours trying to find this.

The data sheet for the XS 12 | 12-50 and XS 1400 are impressive - very efficient.

Are there issues with RFI/EMI (e.g. HF or VHF radio noise) ?  
The data sheet for the XS 1400 says it hasn’t passed the various standards for electromagnetic compatibility (eg ICES003, FCC Class B, et).

Thanks for your help!

As far as i know since the orion xs are all the same family they would be in the same certificate classes.

Certification doesn’t guarantee no interference though, just that they meet a standard.

Installation quality, cable routing, ferrites, grounding, and antenna separation make a big difference, as im sure you know. There are several posts about issues when using Orion’s some install related discussions to minimise it.
