JD, not that it matters much but my unit is a 2000w pro.  I will retest now.

JD,

After changing the setting I disconnected shore power and this time all worked fine.  Last (and only) time the inverter came on for a few seconds and shut off.  Maybe  something else was going on...but for now it's ok.  Will check again at the "Q".

Thanks for the help :)

I can do that with my Xantrex 3000. Go into the Xantrex app, scroll down to Charger, click on "Charger Ignition Control", swipe up to change "off" to "Auto-on" then click "apply". 

Thanks, rich.dev

I think problem may be solved :)

Beutiful Install, Im Jealous you have double the power with my Battleborns. I love the Victron in last two rigs I had , power assist makes all difference in world, I never blow a basic breaker on anywhere I plug into. The only issues I did notice is the victron when charging or running and getting hot vibrates and is noisy against the wall. I placed a piece of bubble foil behind the victron on my install for sound dampening and should have painted the surface with Lizard skin or some sound dampening material.

How noisy is your unit when running? 

Just curious Thanks Ty 

I have ordered the new victron 12v to 12volt charger to charge my Battleborn batteries as the efficiency is 95 percent or more on the unit. I am going to charge those

batteries with a Pecron all in one unit with two 300 packs attached. I like your install with bigger batteries and watch a lot of Will Prowse videos also. 

GREAT JOB!!!!!!!!

Have you installed your Victron 12v charger? I have Hull 292 with the 4045CVS board upgrade to give what I think is ramped lithium charging. Not sure if it is the best option for my 2 280ah Lithium batteries. 

Thanks for any input.

Keep in mind, when running AC, at 70 MPH down a highway, as tight as the Oliver hull is, you're POURING BTUs in the wake behind you! Sitting at a campsite would be say 1.5 less SOC loss and if sitting in the shade, 2x LESS.

Hey @rideadeuce, Buc-ee's is a Texas on-the-road tradition (though I do agree with your sentiment)! When we lived in Georgetown TX, Chris' daughter and grandchild in Houston, we would meet at the Buc-ee's in Giddings TX, for the hand-off, so our grandson could spend a couple days with us! He loved the place. Giddings a great east TX town, great Mexican food and a Super Mercado to stock up the fridge! Ahh, great memories...

Anita and I do love our Buc-ee’s adventure. Mad house, YES! And it drives me CRAZY when people get gas, leave their car for 20 minutes to go in and shop. OK, Rant over.

Sitting outside at Taughannock Falls, NY in a primitive campsite with 25% battery life left (920aH bank). I have been running the AC off and ON for 2 days. First time I have had to put to use all of my battery backups (GZ4K, etc). And yes most of the AC run time has been for the 2 knuckleheads we enjoy so much. Mimi is expecting again!

And, I agree, It just depends how much boon-docking you plan on doing. I wish I had 2000AH!

Best,

Mike

Side note: Starlink is working great!

 

Wow! The picture with the falls is beautiful.  Need to put that spot on our bucket list when we hit the East Coast trip. Our Standard Poodle is Ranger. Got the Oliver because he has separation anxiety when we are gone for a week or two. Now we travel with him. Named the Ollie, “The Range Rover.” We too Love our Knucklehead.

First time I "quoted" my own post! It took 11 days to get an answer...

I sent an inquiry through Epoch's Contact Us page and received no answer. I emailed support@epochbatteries.com with the same question and nothing... Three days later I called their support phone number and got a young guy on the phone. He did not know, but said they had one in the shop, and he could measure. After looking 5 minutes for a tape measure without success, he said he would find one and call me back soon. He never did.

The article re LI batteries suggested buying from an American (Las Vegas, NV) reseller for US support. I emailed them today and they replied, same day and corrected their website page same day, the same mistake that Epoch.com has on their page and will likely be there for some time. Here it is now corrected, and it appears the better reseller: 12V 460Ah - Heated & Bluetooth - LiFePO4 Battery - Epoch Essentials ~ Current Connected

The Epoch Essentials 12460ES battery is only 8.6" wide (as the User Manual stated, but the web page had width and height numbers reversed). This means two (2) of them can fit side-by-side in the Oliver battery bay with the sliding tray removed (I'm removing mine regardless to lose weight and gain height in the bay to get my arms in there for service). Great deal to get 920AH of LiFePO4 batteries for $2,798 total. The reviewer was correct in suggesting an US-based company to provide good local customer service. For many 460AH is quite enough and at $1,399 is an amazing deal! One of these does fit in the OEM sliding battery tray. Heck with the tray, I want two! Looking for Epoch to offer an additional 15% off like they offered for their Black Friday sale last year (coming soon)!

John, I just ordered 2 Lithiums for 560Ah. Will need to also take out the battery tray. Would love to hear what you went through to get yours out. 

Thanks

You may want to consider replacing the stock alternator with a high output unit. I started running into trouble when I swapped out the Renogy 20A DC-DC for a 40A, same brand. At idle, the Renogy was only providing around 25 amps and the TV battery was not being properly maintained. When using the A/C via inverter during brief stops, I generally keep the TV running so the DC-DC can augment the power consumption of the A/C; this has proven to be detrimental to the vehicles charging system! Also, I have issue in stop and go traffic when transiting cities. When running at speed, I get full charger output, but the alternator struggles to keep the TV’s battery appropriately charged. I recently purchased a 320A alternator (at high rpm) to replace the stock 165A, which produces 200 amps at idle; awaiting delivery of supplies needed for the install.

Ron, I have a Nissan Armada, known for Alternator/Battery issues. How is your new 320A alternator working out for you? If it is, please send me the info on it and I’ll see if they have one for my Armada. 

Thanks

Thanks, JD...all makes sense.  I think I may stay with my Xanrex 2000w unit for the time being.  I'm planning to get 2x300 ah Epoch essentials and install at Quartzsite. I want to also remove my battery tray (it is shot) and clean up the wiring. And also explore dc to dc from my alternator.  I am hoping for much input from fellow campers at the "Q".  It is great to know I can switch charging off at night on the Victron...can't do that with my Xantrex.

John

I plan on taking my Battery Try out, when I install my new lithiums. Odds are I will never go back to it. If yours is shot, will you want mine? I’ll be at the April Ollie Rally if you are interested.

Unfortunately, Mechman does not offer an alternator for your Nissan. If you are having issue with your stock alternator, a direct replacement may be all needed. However, in my situation where a 40A DC-DC charger was installed and my stock alternator was aged, the high output replacement was a great solution for my inherent battery charging system problems. If you plan or already installed a DC-DC charger, then definitely consider an upgrade. If you cannot find an aftermarket high output alternator for your specific vehicle, then check if Nissan offers an alternator with a higher amp rating. In my application, the 320A alternator required a ‘Big 3’ cable upgrade, which would even benefit a stock alternator.

Gary, an early thought I had was to remove the tray as Mike did who started this upgrade post. A couple weeks later I decided to go with 2x 300AH Epoch Essentials that fit nicely in the tray sideways. Several other members have made this same battery choice. I believe only @rideadeuce has removed the tray. Mike could chime in, but how to removed the tray should become obvious. Once you empty the tray of batteries, slide it all the way out and you should se the mounting bolts. If I ever decide to add a 3rd Epoch 300A, three would fit in the bay only with the tray removed. Maybe someday.

Which batteries did you order?

I too have been watching Will Prowse and he said good things about the Watt Cycle. I got 2 300 amp hour ones they arrive on the 14th of this month and plan is to have them on before we leave for the Rally. Hope to see you there.

I experienced dropouts on my first install. Measured resistance across cheap fuses in system and found they had high resistance causing heat and cutout also. Awesome install! Run my a/c last week on batteries, working well. 85 degrees out and can get through complete day on my 400 ah battleborn batteries and my victron. Great work!

I’m about to install Xantrex 3000. Are the “Cheap fuses” the ones that came in the Oliver? I’ve got 2017 Hull 292. If so, what fuses did you get to replace them. And because I’m new to all this, where do you install them/between what and where?

Same here and that means there is no GFCI unless running the inverter. It's also odd that Mike with hull 308 has a GFCI outlet and your hull 628 does not, like my old hull 113 does not. Why?

I believe we have two generations of OTT hulls and Xantrex products, mine being a 2016 and yours a 2020. My 2KW Xantrex only has 6 possible connections. On the backside with the fans, there are 3 DC connections, B+ an and B- connected by 4/1 AWG cable directly to the batteries and a 6AWG(?) ground that connects to the yellow ground bus under the rear dinette seat. The front side does have a dual GFCI outlet, rated 120 VAC 16.6A, the monitor cable and LCD screen

The older Xantrex in our hull does not have what you wrote "20 amp feed to the AC input of the Xantrex." Do you have the more modern look Xantrex, fully rectangular, squared edges painted gray? Or does yours look like mine, rounded edges metal looking black vinyl coated? I believe you have the newer generation Xantrex.

BTW, who cares! I'm ripping mine out end of July, the Xantrex, the Xantrex ATS, the funky little electrical box stuck in the corner that connects inverter supply to most 120V circuits, all the but the A/C. I will show my work here and looking forward to seeing yours.

All that matters, is... After all the old is removed, you connect the Victron MP to the batteries in the same way and to the ground bus. You connect shore power from the PD5100 ATS to the AC input and connect the 50A L1 output circuit to the entire Oliver 30A AC panel. This time including the 20A breaker for the air conditioner that was previously bypassed. Can't wait!

Pictures to follow:
1) GFCI close-up on inverter
2) PROwatt SW, with junction box above and inverter below
3) Rear Dinette seat with PD5100, self-installed EMS, Xantrex 2KW inverter and self-installed KISAE TS20 switch for running A/C on inverter.

JD, I’m about to install the Xantrex 3000 with my 2 new 280ah Lithiums. To run the AC off the inverter I saw I needed the KIASE TS20 Transfer Switch. When I went on their website, it says max 2000 inverter. Is there a KIASE transfer switch for a 3000 watt inverter. My search only shows their inverter with the Transfer Switch. 

Thanks

JD, I got these off Amazon after I saw a Will Prowse review with his cut out. 

WattCycle 2 Pack 12V 300Ah（280Ah） LiFePO4 Lithium Battery Mini Size, Built-in 200A BMS, EVE A+ Rated Cells, Low Temperature Protection, Up to 15,000 Cycles(2 Pack).  With the Battery Tray out there is room for a 3rd battery. With the possible Tariff excitement, I’m thinking of ordering the 3rd, before the prices go up 50%. Your thoughts. I also have read if adding a 3rd battery, it should be within 3 months of the first batteries. Don’t know if that is true, or not.

I had the same issue with one of my breakers, specifically a circuit breakers with manual reset. Replaced the faulty stock Chinese made breaker for this one, problem solved. The last pic was posted by another owner and shows the breaker I replaced, labeled 12V BREAKER in his illustration.

Wondering why you're thinking Xantrex now vs. you had an earlier interest in Victron. Why? Oliver owners that have the 3KW Xantrex have them because OTT installs them exclusively. I know of 5 Oliver owners on the forum who have replaced the 2KW Xantrex inverter with the 3KVA Victron Multiplus II. I have never read of any Oliver owners who have upgraded from the 2KW to 3KW Xantrex. I'm not sure of all the reasons why, but Victron has a Power Assist option that allows those on less powerful generators or mooch-docking power less than 15A to still run A/C by combing some battery amperage.

So, there are a lot of Oliver owners and forum members that can help you with configuration of the 3KW Xantrex, but I do not know of any with actual Xantrex installation experience. 

I'm glad that I went with Victron since we now have 6 Victron devices! 🤣 This includes Victron 30A MPPT solar chargers, an Orion 50A DC-DC chargers, SmartShunt and more devices all integrated on one network, viewable on the Victron Connect app. 

Now to answer your question:

When moving up to any 3KW inverter the KISEA 20 Automatic Transfer Switch (ATS) will NOT be needed. This ATS is used as a work-around allowing the 2KW inverter to add a separate 20A circuit to run Air Conditioning (A/C). The 3KW inverters have a built-in 30A ATS that can run your entire 120VAC power panel so that the inverter supplies AC power to all 120V breakers including A/C.

When you remove the old Xantrex, you will also remove the attached 15A Xantrex external ATS and a funky residential junction box, with a maze of wires and wire nuts inside. OTT rigs this instead of the preferred route of installing a split-bus AC panel, allowing them to install the same panel in Olivers with or without an inverter.

Your link was not working for me but I did find the Amazon listing for these WattCycle batteries. I had seen them before, nor the Will Prowse video. Now I get why sometimes you wrote 280AH and other times 300AH! https://www.amazon.com/WattCycle-280Ah-LiFePO4-Lithium-Battery/dp/B0DS48GH5F/?th=1

The 2-pack is a good savings over buying two individually. The 3-pack is the same price as buying 3 singles. If you go for 3, buy a 2-pack and an extra single! Who knows about the effect of tariffs, but all LiFePO4 components even in the "assembled" in USA batteries come from China, and China has had steep tariffs since the first Trump Admin (was 25% now adding another 10%? something like this). China manipulates their currency anyway to be competitive in pricing.

These batteries are 15.1" long, 7.6" wide, so two of these will not fit in the 14x21" battery tray. For this reason and reputation many of us have gone with the 300AH Epoch that are 13.6" long which fits in the tray. Your choice is half the cost though.

Without the tray, my battery bay floor is 18x24" but certainly measure yours as it could be different! Without the tray you could fit three, two put in first length-wise and the third sideways. Running the cables to 3 will not be fun without the tray and you will need to make custom length cables. You'd have to wire and tighten up the bolts on the first two, push them in and then mount and wire the third.

You will also have to figure out a way to strap them down OR cut spacers to fit around and snug them like I did with wood studs. Others prefer using plastic so to have no wood in the Oliver except for the kitchen drawers! The ONLY install we've seen installing batteries without the tray is Mike's @rideadeuce where he installed 2 HUGE 460AH special Epochs which filled every available square inch in the bay, where they have no possible room to move. I forget if he added anything extra to secure them, but you would have to with 3 batteries not filling the space. Maybe you could find a metal or plastic tray just less than the 18x24" space to help. At least line the shelf bottom with rubber as Mike did. Hope this helps and do have fun!

JD, as always great advice. Previous post talked about “BatteryCablesUSA.com.” Good prices for custom cables. I got great info on how to take out the battery tray, the right size bit to take out the rivets and I would have never got the last bolt lose.  I wish I could remember who posted putting the Loew’s plastic board on the top of their batteries with a cutoff switch. I am copying that install and  I could only find an 8 foot board so I will have lots to spare to secure the batteries. For some very strange reason Amazon said I could not get delivery to my house for the 3000 watt Xantrex. So ordered it from a Certified Xantrex Tampa Bay Area Boat dealer. Will find out this Monday if they will have time to install before the rally. Just to be safe, I installed the 4045CSV board to charge the Lithiums. My new to me Armada came with new Weather Tech, so my old ones will line the bottom. If I do buy the 3rd battery, I was thinking of putting them all in sideways. Is there a reason  I don’t know, why you said 2 long way and one cross way. Oh, they won’t push very easily on the rubber mat.  Thanks again for your help.

OUCH. Thought it would be easier to replace the 2000 watt Xantrex with the 3000 Xantrex. Just ordered this weekend. Should I cancel and change to Victron? 

[jd1923]

@Teaney Hull 292 yes you could mount them all sideways. When I thought of mounting 3, I was thinking the first two in with terminals out may be easier to wire vs. having the first pair of terminals deep inside. Either way fits, you’ll figure it out.

I’m not knowledgeable enough on Xantrex to suggest cancelling your order. There are many others here with the 3KW Xantrex who could chime in on their benefits. I read here about others that moved to Victron and their good reputation in the boating world. Now that I have one, it’s been flawless and quiet (under my bed)! It can withstand providing 120V output way greater than the spec numbers too. Like when I turned the A/C on while the hot water heater was also running on 120VAC. It kept both running, no blown fuses! We also like having an all Victron house (see app picture).

Either choice, the wiring is the same. Xantrex would not be easier than Victron unless its size is smaller, don’t know. The Victron MPII is 20” long, must be mounted sideways. I removed the same Xantrex 2KW inverter-only model that you have now.

You’re Learning a lot and also getting a lot done! Best wishes, JD

Either choice, the wiring is the same. Xantrex would not be easier than Victron unless its size is smaller, don’t know. The Victron MPII is 20” long, must be mounted sideways. I removed the same Xantrex 2KW inverter-only model that you have now.

You’re Learning a lot and also getting a lot done! Best wishes, JD

Thanks the vendor opens at 9am and I’ll call first think to switch to Victron. Good news is they are also a Victron Dealer.
