Hi. I have a related question. In order to see the Multiplus on the Victron app, do I need the external USB device always connected to the multiplus? In fact, I see all Victron devices I have installed except the Multiplus 3000. Could there be any other reason for that? Thanks and regards.
Keep up the great videos, Just used this for an installI I did recently. Id like to see more videos for all the victron products you sell and proper settings for each one using SOK batt. Smart shunts, charge controllers....
Thanks for this! One question though: I noticed on your website under the 206 ah SOK you recommend 11v for the low voltage disconnect instead of the 10.5 in this video. Is this because of the larger battery size or just updated info? Thanks again!
Glad we could be of assistance! So many customers get confused that there is no interface on the unit, or bluetooth function, that they thing there are no settings...It's got so much functionality that it's insane.
Helpful video, thanks! Could you advise on settings priorities? There're VE.Configure, VE.Connect apps, CerboGX - what's the priority of settings for the system if they contradict there?
A couple of things...when using with a server battery like SOK 48/100, they have built in charge profile and protection settings, do they not? Won't the Multiplus be conflicting with the inbuilt battery control? Also you didn't mention the first connection of battery to inverter via a protection resistor, maybe that's in a previous video?
I noticed you skipped the UPS function on the grid tab. I seem to remember reading somewhere that this was a good one to disable with LifePo4 batteries. Any thoughts?
This is perfect! Exactly what I need to know for my MP2 installation. Have you all used the Smart Dongle with this? I was curious if I could adjust the input current limit with the app rather than having to purchase a GX or the other Victron panel.
Hi! It seems the SOK kicks in the CMOS when absorption 14.6. It cycles CMOS on and off for 15m before going to float. Is this the desired effect or is 14.4 a better absorption value for SOK batts?
Can you add a VE.Bus Smart Dongle to this inverter and have low temp charging control in case you have cheap Chinese batteries without built in low temp protection?
very well explained, thanks. I install a multiplus II 5000/48volts/70amps (right now with 32 used truck batteries 12 volts 225 amps). - I will buy lithium batteries in 2 or 3 years- What do you recommend to put as upper and lower voltages limits for bulk, float,.....-- (i do not perfectly understand this..) Nb1 It will be loaded with 30 sun pannels 550 watts peak. NB2 I is off grid (used for EV's loading + some of my main electro consumers...). I tested those old batteries (from 12.9volts down to 12.0 they give me easilly 0.6 kwhour back) So time 32 is about 20 kwh available at night . Thanks guy
Greetings. I'm wondering if you can explain the "Float" charge setting of 13.8, and how it actually works (or doesn't), when permantly hooked up to, as in my case, a pellet stove. I have my inverter/charger, with transfer switch, plugged into the wall at all times while hooked up to my lifep04 battery. So it just sits there activated and unused until, of course, the power goes off. Okay, so is this float charge active at all times? Can it do any harm, especially if the battery just sits there? I'm confused a bit on this matter.
Wanting to do the switch to to multiplus 11. Sometimes I might want to charge with a small 2000 watt generator. Would I need to check the weak ac input?
I added solar to my Victron multiples 2 set up. I have Li Pro Fe batteries 400 amp hours. the multiples shows AC input correctly and charges correctly. It shuts the investor off while the solar stilll has the batteries charged. help me program to take care of this problem. Thanks Mike
Look up the charge specs from the manufacturer. Generally Lead open cells are 14.8v charge, float 13.5v equalize 15.8v, sealed are generally 14.4v, 13.5v and no equalize.
Is this unit a split phase 120/240 pass through, I want to use this unit to supply my house sub panel 30 amp. After the batteries are cut off will go back on the main power AC. So I will need to connect both ac in and ac out L 1 and L 2.
If these inverter chargers were designed correctly you should just be able to connect to them with Bluetooth and do this with your mobile phone, you can set up their DC to DC chargers from a phone through Bluetooth but these multipluses are expensive to buy and then you have to buy extra boxes at 200 quid a go in order to get them working!
Can you use this program with an Cerbo GX (or at least do the same stuff with it?) or do you have to use that usb dongle ? Cost of this systems starts going bananas with all the addons you gotta buy to control it in different ways i think :)
Did you ever get an answer for this? I have the Cerbo GX, and the Bluetooth dongle, but not the USB dongle. I didnt know I needed it. Can I do this with the Bluetooth dongle, or through the Cerbo?
Divided between them...But out-2 is only powered when shore power is available, so thats not really fair to say because they can feed-through MUCH more than 3000w.
I have the same inverter. However, I've never been able to see L1 and L2 separately via VictronConnect or the Cerbo GX. I don't know the firmware version, other than mine was one of the first units sent to North America. My installer has been hesitant to install the firmware update as there have been reports of excessive noise, where mine is quiet as a mouse unless there is a heavy load on it. Is there a setting or something I need to do to see both legs?
I had this same problem. No even victron could help me. Finally . Another RU-vidr told me how to achieve this. In update feeds- select - latest release candidate- then do a firm ware update and you will see L1 and L2 - this is done on the touch 50 screen
Witch setting do i need to adjust if i only want to charge the battery at charger only and at the same time keep letting shore power go through the invertor
Turn the power switch to the other direction, instead of position "1" go to position "2", or select charger only function within a Cerbo-GX or Digital Multi Control.
Hi thank you for the video. Can I connect the multiples ii on a switch and from anothe port of the switch connect to the usb adapter and of course the usb to the computer ?
No, this is a VE.bus signal, not a ethernet network signal. you can only connect the VE.Bus to the victron devices. Each device has 2 ports, so you can daisy chain them.
Why is it recommended to use more than one battery? Wouldn't the inverter load determine the total amp hours needed from the battery bank? Just trying to understand that recommendation
Yes, but in the case of the SOK battery, each battery may have plenty of capacity, but you can only discharge at a rate of 100a, which means approximately 1280w per battery (100a * 12.8v). This means to power a 3000w inverter, you need at least 3 batteries to meet the demand, otherwise you must derate the inverter to prevent overloading the batteries.
There a couple of settings I may want to change from time to time, like battery charge amperage and dynamic assist. Is there a way to change these using the Victron Connect App or Cerbo GX Display interface or perhaps the VRM Monitor website? I have the ability hook up my laptop using the MK3-USB unit, but it would be nice to make these mods without having to tote around my laptop every where I travel. Thanks
So as I was following the pictures from your video and instruction at the end it told me virtual assistant was on In your video you did not uncheck that box and I assumed that was just a default. Do I have a problem? When I clicked show me where it did not work to show me I believe it loaded AlSo we want to practice making changes while we have our windows here Do you have a video to link for that
Hi Dena, great question. I think you mean virtual switch, not virtual assistant. I suggest unless you know how to use virtual switches, then just set the option to "do not use virtual switch", and on the assistants tab, you shouldn't need any for normal operation.
When I set my Multiplus absorption voltage above 14.2 my 150/85 smart solar MPPT goes into over voltage error when the multiplus is in absorption mode. RV Setup: Three 206ah SOK's with bluetooth bms, in parallel, Victron multiplus 12vdc 120 vac 3000va, Color GX, BMV-712, 150/85 MPPT, 100/50 MPPT. Float and battery full settings at 13.8 vdc. Max charge current set to 120 amps. After 1 hour initial multiplus absorption two batteries are just over 14v. One is 13.7v. The reason it goes over voltage above 14.2v is that a voltage spike occurs when the battery bms cmos shuts off. One of my solar charge controllers is sensitive to this and goes into the error condition shutting down. The battery bank does not completely fill from the multiplus at 14.2 absorption. I have the MPPT's absorption set to 14.8 so there is a chance it will fill and balance out when off shore power. Is there a solution.
@@CurrentConnected I used the cerbo GX/VRM as you say and was also able to upgrade the Multiplus latest firmware. I had to borrow a PC to do it - as it was not Mac compatible
@@CurrentConnected That is not true! I updated from 481 to 490 it did not make any difference. So what is the reason that it makes the buzz? (mp2 48/5000 from feb 2022) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_2jIfDpwPjM.html
The resistance in a DC circuit is pure resistance, which is limited to the impedance (measured in ohms) of the conductor(s). Thus, watts are a good measure of “real power,” and if you have three 120 VDC devices calculated to work at 200 watts, 400 watts, and 600 watts respectively, then you can just add them linearly to know how much power the circuit requires, which would be 1200 watts (1.2 KW). In contrast, AC circuits also have inductive resistance, mostly caused by the build-up and collapse of the current with every 60 Hz excursion of the sinusoidal wave. This means that depending on their respective amperage requirements, three 120 VAC servers rated at 200 VA, 400 VA, and 600 VA respectively will not necessarily add up to 1200 VA (1.2 KVA). In sum, “volt amps” is a warning to proceed with caution. You created a very good video that I found very helpful, however, you cannot use watts and volt-amps interchangeably. You should use the term that Victron use to rate their inverter Volt-Amps
@@CurrentConnected so, I do have another question. I am very interested in purchaseing two for split phase. And I'll be connected it to my houses. Breaker panel. Not sure if it's bonded or not. So if it's bonded do I have to remove the bonding bar? In order to connect to ac input?
@@carlosreyes6448 No, just turn off ground relay in the inverter and use the existing bond - unless however, you are feeding a subpanel, then you would need the relay enabled.
That's very strange! This link should take you to the page on Victron's website that has all their software for download: www.victronenergy.com/support-and-downloads/software
Hi Brad, are you using VEConfig program, or VE.Bus Config, or VE Quick Config, the other two software packages that are included from the download link? The proper one is VEConfig
In my testing, if you fully charge / top-balance a cell at 3.65v, after resting for 24 hours the float voltage for a healthy cell is right at 3.45v. The thought process is that if this is the resting voltage, then if you float at a lower voltage, you are partially discharging the battery already, even though the charger function is on and operating.
@@CurrentConnected Victron has the victron connect app for the MACs. Once you connect the USB dongle additional menu items show up that allow you to do the programing you see in this video. The layout is different, but everything talked about in this video is able to be set using a MAC, you do not need a windows VM. I just did this today.
DO not charge LFP to 14.6 V or 13.8 float, U will kill LFP, LiC6 and LiFePO4 + LiPF6 + DMC + EC + EMC do not need such high voltages. And tell me what storage and working temps fo U have at cathode and anode of LFP.
Victron's communication protocols are such a joke they have three different systems USB and their two proprietary delusionary connections. The fact that you can't just use a USB or a cat cable for everything to communicate which has been standard protocol for the last 30 years is just pathetic victron refuses to innovate just sticking with old outdated technology that just has other technology slapped on top of it that's why victron systems look like a a octopussy orgy with black and red tentacles not to mention their non-ul approved electrical connections on their equipment which has caused many issues but yet they refuse to acknowledge it. And pass it off as the user air their own information contradicts itself between their manuals and their website.
I totally agree. I've seen videos where victron people don't understand all the protocols. Would have gone with another manufacturer if I had realized the connection mess.
Im trying to do this on my macbook pro but it wont work, "You can’t open the application “VECSetup_A.exe” because Microsoft Windows applications are not supported on macOS."
It may be that you've tried to install the Windows version of the software instead of the Mac version. This link should lead to the download for Mac - apps.apple.com/us/app/victronconnect/id1084677271?ls=1&mt=12
Current Connected, I'll be hooking up the older Victron Multiplus 12v/3000 soon and was wondering it this video tutorial would essentially apply to me unit as well?
