Default Lithium/Alternator/Inverter Package from Xantrex

Xantrex has developed a Lithium/Alternator/Inverter Package that is now available on the 2018 Coachmen Galleria Li3. Package includes a 600 AH Battery, 250 AMP Alternator and a 3000 watt Pure Sine Wave Inverter. I'll be attending the Tampa Show January 17-21 and gather info/specs/pricing. My first question will be if there are plans to make the Package available for Authorized installation in existing Coaches. IMO, this is a Game-Changer 😀

I have seen the Galleria order form and this is a $21,000 option.

.

Just my 2 cents,
I would not hold my breath waiting.

I doubt CM will make it a retrofit option.

You might be able to get a similar package from an upfitter shop,
but not from the CM.

The reason is simple -- why bother?
What is in it for them?
It is a lot of work to tear up the interior to install the new system.

I cannot see it as a worthwhile proposition for a factory operation that has a production routine and a demanding schedule.

CM is in the business of making new coaches,
not tearing up old ones.
There is a lot of risks to assume when dealing with an used RV.

A custom upfitter shop or Li/Solar shop would welcome such a retrofit project.

Does anyone have any information on how they handle the cold? They say usable to -4*F, but we all know that would be discharge only with charging to 32*. Are there heaters and how are they run if they are there? Can the batteries be easily removed for cold storage, or do you need a lithium condo like ARV, as -4 is not even cold around here and it is the now often stated cold storage damage point? Cold and hot seem to be the biggest weaknesses of lithium for those of us in the north, after cost of course.

Even at 21k, it's close to what roadtrek charges and the quality parts will be night and day better. While 21k sounds expensive, the sum of the parts are approaching 21k. Xantrex makes rock solid parts as does lithionics. It's really nice to see high quality parts for a setup like these compared to roadtrek's in house BMS that's power hungry and cheap re-branded AIMS inverters.

Can you design a similar system yourself a lot cheaper? Hell yes. In fact, you could probably design the exact same system using the same parts:

600AH lithionic battery: $9500
Nation's Second Alternator with regulator: $2200
Xantrex Freedom SW 3000 with remote/combox/monitor: $2500

Not sure if solar is included in their 21k price tag or not.

But people in the market for a 6 figure class b probably don't want to mess with installing a system like this on their own.

My guess is they can't handle the cold as they've listed their operating temps. However I doubt the van would be subject to that cold of temps while you are operating the van as I believe the battery is installed inside the van to keep it out of the cold. So if you heat up the van to provide yourself with warmth the battery should be warmed up as well.

As for cold storage and removing the battery, that shouldn't be needed as the BMS will disconnect charging loads at freezing and I assume all other loads at -4. The battery weighs 150lbs so I don't think it's meant to be moved that often.

The latest information, via ARV and others, is that the lithium batteries can't stand to be STORED, even disconnected, at below -4*F without damage, which can be a very big deal in the north.

Here is a link to the Lithionics site about storage requirements

Right now, for the Transit, the house batteries are under the chassis, on the outside, below the driver's and passenger's seats.

Not sure where would they put them inside the coach.

Interesting. I guess I never looked into it much as I don't get down that cold around here. I've always read with no load or charge you should be fine, but that may be incorrect.

My guess would be under the bed, under either seat in the back, inside one of the cabinets, there are a lot of options on where this can go. It's a big battery for sure, but it's a VERY long van.

At -4 degrees F the LiFePO batteries can be damaged if they are allowed to reach that temperature or below. Advanced RV installs 12V electric heating pads sandwiched between batteries designed to keep them above 41F at all times so they can accept a charge at all times. The pads draw 10 amps or 240 amps in a 24 hour period. I haven't experienced them to come on until the temperature drops to about 20F ambient and it can still be intermittent. At -20F ambient to heating pads couldn't maintain the batteries 42F. For those anticipated conditions ARV now installs more heat. So as long as you maintain a charge the batteries themselves will supply the heat but the obvious solution in storage is to provide shore power to keep the batteries charged. While underway and traveling the second alternator provides charging and restores 240 amps in about an hour of driving. I have gone a week on the road where the temperature was constantly below freezing 24/7 and got down to a -5F.
