Victron Multiplus II 3000 - Installation Xantrax Removal

[Ty J]

My Victron worked excellent this summer. Im not retired but still spent 35 days this summer in my camper. I love power assist. Ran batteries Dead only 5 times on trips. I only have deployable solar panels. Im expermenting with a pecron and victron dc to dc charger. It has 4700 wh on it. I Trickled charged my Battle borns with 130 watts.  Im currently putting in DC fridge. Thanks to everyone in the forum also adding the table on outside that is included on newer models. Thats my winter projects. I am overwhelmed at work and have not logged into forums in while. Multiplus is working well. Powers my a/c for about 5 hours. Have original penguin II. Expermenting with new flat solar panels from Bouge RV going to mount on top of oliver. 2021 Oliver Elite II. Only issue I have seen is when the victron is running hard its fans vibrate or radiate through the olivers fiberglass walls under my bed. Hottest it has been in cavity with Victron is 94 degrees , we had a mild summer in Montana. Did not get overly hot, like last year of 104 for 4 to 6 weeks. Weather has been all over the board up here. With the victron i set it to pull1200 wattes from my house plugs and can run a/c plugged into my normal outlet at house or anywhere. THe a/c will pull around 1450 watts , it just pulls extra wattage from battery bank and recharges them between cycling of the a/c .

Take care 

 

 

 

My rig did not come with solar. Going to try flat panel on top. Little scared about heat impact on fiberglass, have used flat panels in past get extemely hot underneath.

Merry Christmas.

The main reason I would swap out my  Xantrex 3000 to the Victron Multiplus 3000 is Power Assist. 

What size cable did Oliver install leading to your Xantrex 3000, was it sufficient enough to accommodate the Victron or was it necessary to increase the cable size for the swap? My Xantrex Freedom XC 2000 has 2/0 cable and thinking it would have to be upsized for a similar install. Your pics show you installed the newer MultiPlus ll model, good move; and thanks for the update!

My trailer is in storage but I’m pretty sure it’s 4/0 AWG cable.

Maybe this question was meant for someone else, I still have the Xantrex?

Used 2/0. Changed out stock cables. Want to change out stock fuse later down the road also. Just need the time.

So the 2/0 ‘stock’ cables were changed to what size, 4/0? I’m only thinking ahead, so a response when you find time is okay. Again thanks.

I believe stock was 1/0 they were smaller and I had a bunch of 2/0 left over from my last installation on my lance.  I had ton of 2/0 used on my Lance install. Thanks

If that is the case, a swap/upgrade to a 3000W inverter may be easier and less expensive than first thought. 

Current Xantrex Freedom XC 2000

Input cables are 2/0

 

If the hard reset (reboot) currently being conducted doesn’t resolve the charge cycle issues with this inverter, then said swap/upgrade is inevitable. Again, thanks for the info, much appreciated!

@2500 watts and 12 volts Your amperage would be around 210 amps  most I ever plan to use.

Keeping the length of cable down is critical. Keeping cables under 10 ft should be o..k.k. for 2/0 according to many of charts I have looked at. Critical to have good fuse. Thats what protects your wiring.

I am thinking about swapping out Xantrex 2000 for a Victron Multiplus II 3000 and installing upgraded Lithium batteries. The part that I need help with is the wiring from the PD 4000 distribution panel and bypassing or disconnecting the charger.  Still need converter portion for shore 110v?

MP2 for Inverter DC to AC, power switch (Shore to DC, DC to Shore) and charging. 

Does the OEM wiring from the junction box on Xantrex end just go into the AC IN and AC OUT on the Victron Multiplus? Or do you need to run the shore power out of EMS to Multiplus AC IN and then back to distribution panel. 

Do you simply disconnect charger?

If you run new longer feed from the EMS to MP 2 AC IN then can you use the AC OUT back to the PD 4000? OR does the EMS to MP2 go back to shore power in the same AC in on back of PD 4000. 

Any clarification on these questions or pics would be greatly appreciated. Just trying to figure it all out before hiring someone or diving in myself. I, also, just want to understand how it works. 

Thanks in advance for any feedback.

I my xantrex had dc charger built in. I rewired my total dc side though did not like wiring from factory. You should be able to remove the dc xantrex charger. Yours is different layout would have to follow your wires. Never touched ac side at all except hooked up proper breaker to proper spot. AC on fridge and ac on air conditioning were wired backwards from factory. Found that out when tried running AC off my batteries alone. Rewired dc side with victron shunt and lynx distribution on fender well. Very tight
