Dual Orion XS wiring kit coming soon. Orion 30A to Orion 50A retrofit coming soon. Stay tuned to our social media for the announcement for those.

NOTE: I'm sending this everybody on the waiting list at the same time as well as a social media blast; and there are a lot more on the waiting list than I have available as of today and these WILL SELL OUT, But... since we have gotten our first shipment, that gives me confidence that we will have more in a timely manner; which means that we will be taking backorders. This means that if we sell out, you can pre-purchase for our next shipment and we will fulfil those IN THE ORDER THEY ARE RECEIVED, so time is still of the essence if you want one.

So, when will the next shipment of these arrive? Our current best estimate is April 26th for the next small shipment, and then by early June, we anticipate having enough to fulfill ALL orders.

Thank you for putting in the conversion sizes (mm², etc)😊. Not many people do that. Very informative, as ever!

Great explanation, although I'm curious how the distance calculation varies if you're using chassis for the negative.

Hi from the freezing north of England! Great summary 👍
When updating, please mention the in-built cable clamp as Victron imply the ‘connectors’ need this unusual mechanical security for longevity.
I found the lack of VE.smart network an unwelcome surprise. I’m having to incorporate a separate low temperature disconnect unit to protect my lifepo4 battery. Hopefully they will have a firmware upgrade before next winter!

Excellent!! Thank you!! I was preparing myself to have to upgrade wiring. Phew! What a relief!

[chinookguy]

I love your videos! as soon as I find the perfect van, I will buy a kit from you!

How about if I want to double up and use 2 for 100amp total?

I recently found your site and am loving the videos. I am planning two anderson type(or similar) connectors in line to the camper. How do these affect voltage drop? I will check back weekly for a link to the 12-12 50 as I don't see it currently listed in your store. Thanks.

I love how you explain all of this stuff. I’m confused about my Ford Transit charging system. How do I know if I can add a 30 amp charge controller to my starter battery?

[ModernSurvivalSense]

Ok so crazy question... These recommendations are for the input side. What about the output side? The use case is as a recharger during power outages for a (mostly)portable system that resides away from the vehicle and continues to power devices. Technically, it could be moved closer to the vehicle, but it's not overly practical.

Also... can you "cheat" the recommendations by having a shorter negative that is grounded to the chassis?

Is it safe to use the vehicle frame as a common round for the neg running on the tow vehicle portion if going to a trailer?

Thanks for the great, highly educational videos. I have really enjoyed learning from all of them as I have done various lithium and solar upgrades these last couple of years. Do you have a video that talks about what to do in the case where the RV manufacturer assumed lead acid vs Lithium and used a battery joiner solenoid for house battery charging off the altenator?

Even though my 2023 Newmar New Aire came from the factory with 640 Ah of Lithionics batteries (with a later factory upgrade of a 3rd Lithionics bringing the total up to 960 Ah) they still used an old-school Xantrex solar controller (that cannot spell Lithium and they now have a service bulletin/recall out for well over 100 vehicles) and battery joiner solenoids. I have already ditched the nicad/lead-acid solar controller for a Victron SmartSolar MPPT myself thanks to your videos, but I still don't like that the rig uses a solenoid for alternator charging vs DC to DC charger(s). I'd still like to use the solenoid for combining batteries for a boost if needed when starting the rig, but I feel like I should rewire in a new Orion XS (or a couple) for altenator charging. That said, I need to deal with the solenoid, no?

My previous rig, a Tiffin Wayfarer also had a solenoid, but putting a BIM in its place was a simple remove and replace exercise. But, had I gone with a DC to DC charger there, I would have had the same question as I do with this new DP, no?

Thanks!

Hello, Love you work and much appreciated. Looking at this video I belive there is an error in the wiring diagram (3:41). It seems the positive wires as shown are reversed (IN vs OUT). The Orion XS wiring kit diagram on your store shows correct wiring.

Could they have released this version of the Orion @ 50A to conveniently fit below the 60A CCP1 in Ford Transits? The Transit CCP1 fuse is notoriously hard to change so im a little nervous to follow your advice of a 60A fuse downstream of that.

With the 12/12/50 non isolated, can I use this on a boat and is so how do I earth/ground being the boat doesn’t have a Chasis for grounding the negative bus bar?? Thank you 🤔🧐🙏🙏🙏

[francoispoitras]

Hi, in your wiring arrangement to connect the XS, would the Lynx be grounded to the chassis? Thanks

[henrikh]

Telt me how much current is actually flowing in the negative wire while it’s charging 50amps, gotta be close to zero amps?

[tannerjim]

Can you see any reason to connect the Orion XS to my CerboGX if my setup is Truck/5th Wheel? I'll never be able to see power input while driving, but I guess I could have my wife monitor it via the phone app.

[MichaelOlsthoorn]

I have been waiting for something like this for a year. I was thinking of using an Anderson connector between my pickup truck and travel trailer. Would I run a positive and negative cable « to and from » the starter battery and positive and negative to the Orion from the Anderson? Would I also need to run a negative from the Orion to trailer chassis? Txs😊

I’m installing a 50A dc-dc charger on a truck camper. The wire will be installed inside an engine bay and covered in split loom conduit. What is your recommendation for wire in this install?
