Hi there.


I'm in the process of making a list and trawling through all the documents I can find on how to pair the BYD batteries with a Victron EasySolar or MultiPlus for an off grid setup. Basically, my setup will be as follows:


All control gear and batteries to be stored outside, but under an awning.

2.8kw of solar, which will work with a 150/70 MPPT charger.

BYD B-Box RESI IP55 cabinet with 5.12kwh battery

Either the Easysolar 48/3000 or the Multiplus 48/3000.


Can anyone who is familiar with this combination tell me if there is any advantage to choosing the Multiplus unit over the Easysolar? The Easysolar works out cheaper than buying all the parts and cables individually, but I've noticed that the IP rating on the Easysolar is only IP20 though, so maybe it's not suitable for installations outside?


Any thoughts or suggestions would be much appreciated.


TIA

Hi,

my friend who sell Crown Batteries in my island ,told me that he will soon get the AQ-LITH ENERGY BOX to sell . And hel told me too ,that Victron Multiplus works well with these lithium battery...

Do someone knows if this systems needs a BMS or a bus can or something like that,my friend was unable to answer me

Hi All,

I have a MultiPlus Compact 12v/1600va/70a with a digital multi control panel.

The system was installed on my boat less 6 months ago by a marine electrician in the UK, the boat and me are now in Valence, France.

I am connected to 16amp shore power, the multi control is set to charge only, current limit dial is set to 16amp, there are no warning lamps.

Until the last few days everything has been working well, but now when I draw current above 11 amps the 16A breaker switch on the front panel of the MultiPlus Compact trips out within a minute or so.

The breaker on the front panel of the MultiPlus Compact has tripped previously if i have inadvertently pulled more than 16 amps but is now doing it at only 11 amps.

My main energy use is 3 x 1kw oil fired radiators which pull a total 12 amps meaning I can now only run 2 of them and it is getting very cold here !

please can anyone help?

I intend to use a third party LiFeYPO4 battery and use the Aux/Temp-Sensing mechanism like it is described here: https://www.victronenergy.de/upload/documents/Manual-Connecting-other-lithium-battery-systems-to-Multis-and-Quattros-EN.pdf

I will also use a CCGX for monitoring.

My question is: If there is a overvoltage condition

Are the ports monitored all the time even if the charger of a MulitPlus is not running?
And is the current status sent to CCGX and then forwarded to Smartsolar via VE.direct so that Smartsolar stops charging?

If not, is this possible with a different monitoring device?

Kind regards
Peter

Hello and Welcome!

These are some of the Victron Community guidelines. The community is predominantly volunteers, and the vast majority of the answers are provided by enthusiasts. It is not an Official Ask Victron site, for that please use the normal line of support.

Read the Victron Support page, and follow the steps in order

After you have read the Support page, if you believe that Victron Community is the best place for your enquiry, please search the previous posts. If you find your question already answered, please give it an upvote.

If you cannot find a similar question, register an account and prepare your post.

You will need to provide some basic information before you can post a question.

Try to limit the Subject and first line of your post to a single, short, question.

This can then be followed on by further background information to provide context, examples or attempts you have already made to address the issue; If you think it will help in answering.

One Question per post

This community is intended to become a knowledge base. We want people to be able to quickly search for their question, and find the answer. Ideally the answer is a link or reference to the precise Victron documentation.

To help with this, if you have follow up questions that are different from the original, please create a new post. If we think that multiple different questions are being asked, we may ask you to split them up.

This allows future users to find specific questions, and clear precise answers very quickly.

If you try to ask follow up questions in the same post, they are likely to be missed, because the original question appears as answered.

Not really the place for System Design

Long, multifaceted issues involving system design, multiple run on questions with very specific installation and nuanced details are not really well suited for the structure of the community. It is best to have a single question with a clear title per post. More complex enquires are best be directed towards your distributor.

Constantly Improving Documentation

Victron is constantly improving documentation, every single day something is updated.

It is ok to ask questions that may be in the manual, though we ask you to also look yourself, and self-post the answer if you find it before someone else does, ideally with the manual and section reference.

This can help others, and also help Victron to make manuals clearer.

Choose A Good Topic Title

Please use an appropriate title when asking a new question. “No lights on 100/50 MPPT” is a good title. “URGENT HELP PLS!!!” is not. This helps those who have specific product knowledge find your question to answer, and also others who might have the same issue find it easily later.

Editing Posts

Occasionally Victron will edit questions, topics and answers if we think it will be helpful or add clarity.

Hello Victron community,

This is my first post and my first off grid system which I am still getting used to.

I have a Multiplus 24/3000/50, CCGX and six Northstar Blue NSB210FT. Now I know there are issues using these AGM batteries which require equalisation for 16 hours every two weeks.

I have tried the first equalisation today by flicking the switch on the multi which worked and went into equalisation mode but it seems to switch back to float after about an hour.

Is there a setting to increase the time?

Also to get the Multi to start equalisation I use the MK3 dongle and enabled equalisation in the VE configure but it mentioned “tubular plate batteries”, not sure if my batteries are tubular plate of not?

firmware on my Multi is 1910142 so assume it has the old microprocessor and that I can’t initiate Equalisation via the mobile app?

Any help is appreciate.

Thanks

Many thanks for any help with this.

Hi I have van setup with dometic charger inverter and dometic booster.

I use victron 160ah lithium battery with li load relay atm.

Chargers are set to iuou 14.2v float 13.5, I can modify voltages.

Also there is victrom ve bus bms connected to li load relay.

Charge disconnect wire isnt used at this moment.

Now questions

1) can battery stop charging below set temeprature without li charge relay?

2) battery averages around 13.2v after long charge is this normal?

3) if I use li charge, it will disconnect during float phase 13.5v bcs its written there 13.7 charge is minimum for it to be connected?

4) I can set chargers to constant voltage, 14.2 wouldnt that be better?

Hi,

First time poster. I have been using my Multiplus mainly as a battery charger successfully for about 4 months. I bought unit second hand and didn't realise battery charge settings could be changed via dip switches. The settings were such that at peak charge flow I tonged up to 70amps on the 24v side. This high charge rate was occasionally overloading my 3kva inverter generator causing the generator supply to fail, thus causing the Multiplus to cut in and out quite frequently from ac in. I suspect this has damaged a sensor or pcb component as now when I connect generator supply, the Multiplus senses the generator supply and after the set time attempts to transfer to ac in but immediately switches back to inverter mode.

I would ultimately like to diagnose this fault from home and order parts as the unit is working fine as inverter and I am currently powering my home off it.

any help would be much appreciated. thanks.

Model is PMP245021010

Serial is HQ14489ZIND

Multiplus 12/3000 V465

Using Victron Connect v5.16

I set the Conditional AC input control on and set the voltage for 12.65V, but when the voltage drops below that, it fails to switch back to the grid.

We have two existing 250/60 mppt controllers (PID:0xA05D & FW:139) which connect fine via Bluetooth and VE.Direct. Our brand new 250/60 mppt controller (PID:0xA068 & FW:147) works, but we can't connect via the latest Victron app to change settings or see history. Both Bluetooth and VE.Direct methods say "Unknown Product (A068)" when we try to connect. The only way we can get data from the new controller is via VE.Direct rs232 comms.

Why are the new controller PID and FW versions so different from our existing up-to-date controllers?

Hello I have 2 multis installed, I want to parallel however they have different firmwares one is 2614413 the other is 2614430 I have tried to update to either /30 none of them is responsive. How do I go about this issue since they need to have the same firmware to work in parallel or split phase.

Hello

I'm new to Victron Energy devices and I have a Color Control GX. I'm looking for some help/tips.

1. What ports are used by the device to connect to the VRM Portal?

2. Where can I find the latest Firmware, if the device is not connectet to the Internet? I didn't find any Firmware on the Website.

3. I can connect to the CCGX by LAN. The Webinterface is working and I'm using the Webinterface in PRTG (iFramein Website) to display the status. After about 24h the Webinterface is not responding anymore and the CCGX has to reboot. If that happens, the CCGX is still reacting on Ping. Does anyone have a Idea, what to do?

Thank you

Regards

Hi. So my alarm in motorhome was saying leisure battery was overcharging. A 120w panel and victron 75/15 charge controller as been powering up my leisure battery fine for around a month. I connected up to a spare battery and its going up to 15.1 before I disconnect it cause seems to much thanks steve

Hello Victron Community!

I've recently finished building a system for my off-grid cabin, and was in the process of testing it out today. I am running a Smartsolar MPPT 100/50 charge controller with a BMV-712, as well as a Multiplus 120v 3000VA inverter/charger. The batteries are Crown 6CRV220 AGM (qty 4) in a series-parallel arrangement for a total of 440Ah @ 12VDC.

Today, I was testing the system with one panel connected (Renogy 100W). The inverter/charger, when connected to Mains, was able to successfully reach float....however the MPPT never progressed past Absorb.

I have my battery settings set (in both the BMV and MPPT) to 440Ah, 14.52 Absorb @ 6 hr max, 13.2 Float. The batteries charged to about 13.55v and sat there consistently.

Any thoughts on why the MPPT would not proceed to Float?

Thanks!

I’ve had an error come up on one of our GX devices saying “Internal Error Alarm”. This seems to be related to the BMS in our Pylontech batteries.

All I can find in Victrons docs is under https://www.victronenergy.com/live/vrm_portal:alarms – the last line in 2.1.2. Although this is no help; it only shows me that it’s an alarm that is being monitored.

Can you please tell me what this alarm means?

First post - A little guidance please on our design below:

We have 48 PV Panels each has an Enphase 215w micro inverter.

We have a genaration meter as part of our FIT

Our utility provider has installed a smart electricity meter to track half hourly usage

Would the below design work for us?

Our decision to connect the PV to the critical loads output (AC output 2) of the Quattro is to ensure the continuous supply from PV and battery in the event of a grid failure.

1) If we connected the panels to the Critical load, as mentioned in step 1 of the installation guide video at 7 minutes into it (https://www.victronenergy.com/live/ess:quick-installation-guide) - Would this work without the need for the additional ET112 meter?

2) With this setup, would we have use of the CCGX to show system energy flows and be able to control the system via the CCGX?

Thanks

I have two Victron Quattro 8VA units installed in a marine application with one acting as a master and one as a slave. When turning these units on and off is there a preferred sequence I should use? Both simultaneously? Master first and then slave? Slave first and then master?

Hi, new to Victron products. I'm looking to install a Victron charger/inverter setup for my toyhauler.

Looking for a 3000W setup, i'd like to power both phases of my dist.panel either from shore,gen or inverter.

My current setup: shorepower is 50A, generator is Onan 5500, 4x100A Battleborn batteries, flexmax 80 solar charger and 680W solar panels.

Any inputs would be appreciated..

thanks

Hi all,

Margreet Leeftink, Sales Manager & trainer in Australia has compiled the second Victron book: Wiring Unlimited.

I'm posting it here on Community as a preview; please put in your comments so we can make it even better before publishing more publicly.

Download your copy here.

I could of course here tease more with whats inside; but better just click the link and see for yourself. I think its a great step forward of bringing all information together as opposed to it being scattered around.

Thank you Margreet for this excellent piece of work! Wie schrijft die blijft :-).

Best regards,

HI guys,

Can someone with expertise with the Argofet help me, I want to add an Argofet to split charge my VRSLA start battery and my LFP house bank. Easy so far. I want to connect an MPPT controller to the input of the FET and utilize the alternator energize circuit to tell the MPPT that there is voltage. The solar controller needs to see voltage at the battery terminals or it wont start charging.

This is what I had in mind, will it work?

[image]

The following is from Victron ArgoFet documentation...

Alternator energize input
Some alternators need DC voltage on the B+ output to start charging.
Obviously, DC will be present when the alternator is directly connected to
a battery. Inserting a Diode or FET splitter will however prevent any
return voltage/current from the batteries to the B+, and the alternator will
not start.
The new Argofet isolators have a special current limited energize input
that will power the B+ when the engine run/stop switch is closed.

My Multiplus switches between charging state prematurely. It will change from bulk to absorption between 85% and 88% (SOC), but I have the bulk state set at 90% (SOC) (see image 1 below). From absorption to float between 90% to 95% (SOC) (see image 2 below). I always thought the float state would be 2 amps or less. Can someone tell what is going?

In my Airstream travel trailer I have two 300ah 12v Victron Smart Lithium batteries in parallel, BMV 712, 800w of solar, Victron 150/70 MPPT controller and MultiPlus for shore power / genset power for charging.... and CCGX for system coordination.

I also own a Telsa, and the best practice, generally speaking, is to run the lithium pack between 30% and 70% SOC to maximize longevity. We only ever charge to 100% ever 2-3 months when needed for extended use. It has active cell balancing, of course.

The Victron batteries have passive cell balancing, which of course means you must charge and float at 100% SOC to balance the cells.

My question is - does charging the Victron 12v Lithium batteries to 100%, over and over again (on a daily basis) degrade the performance of the Victron lithium cells at an accelerated rate? Or... should I manage the batteries like I do the Tesla cells - between say 30 and 70% SOC, and only fully charge / balance on, say, a monthly basis?

In other words, what are the best practices for yielding the longest lifespan / longevity from Victron 12v Lithium batteries aside from caring for them with low charge / discharge currents?

Thank you Victron community :)

Ich möchte ein ESS-System aufbauen, und habe viel in Equipment investiert. Batterie ist wie hier beschrieben eingestellt. Das Venus GX erkennt das BMS des Pylontech US3000 nicht. Das Typ-B CAN to VE.Can habe ich mehrmals durchgemessen und entspricht der Beschreibung. CAN-Bus-BMS (500Kbit/s)

Der Testaubau sieht wie folgt aus:

[image]

Die beiden hellen RJ45-Kabel sind mit MK3-Konfigurator bzw. Internet verbunden.

Unter den Devices wird nur der Temperatur-Sensor angezeigt. Die Batterie fehlt und wird auch nicht geladen. Die Firmware vom Venus ist aktuell (2.42).

Über die CAN-Verbindung scheint die Batterie vom GX-Device nicht erkannt zu werden. Der MultiPlusII wird auch nicht angezeigt, obwohl mit UTP-RJ45 mit CAN-BUS verbunden.

Wie kann ich die Kommunikation zwischen PYLONTECH und Venus GX überprüfen? Gibt es Testtools mit dem MK3-USB-Connector?

Ist es richtig, dass das GX über den CAN Bus dem MultiPlus-II sagt, wenn die Batterie geladen werden soll? Die Konfiguration vom MultiPlus-II erkennt AC in, AC out und die Batteriespannung, aber geladen wird nicht.

Ist Vielleicht das Venus GX defekt? Ich bin nach 3 Tagen Suche schon total verzweifelt und kurz davor, alles wieder umzutauschen. Hat jemand eine Idee?

Viele Grüße

Beate

I'll keep this short. My Victron Phoenix Inverter Compact 12 | 2000 230V (an old microprocessor 230VAC inverter on firmware 1908209) is not compatible with the VE.Bus Smart Dongle and will never be, corrrect?

I think I might be doing something wrong but I've seen some strange behavior with my ACOut2 Relay. I have an assistant that disengages the ACOut2 relay if ACIn2 (Grid) fails. Now you might wonder why because it's the default behavior anyway. ACIn1 is my Generator Input and when the Generator runs I want ACOut2 also to be disconnected. The Generator ONLY runs when there is no Grid power so the logic seems right. It's also a manual start generator so I decide when to power it up (usually only after very long outages).

It all works perfectly except it 'looks' like in a very specific situation it does not work at all.

Here is the scenario: We have somewhat unstable power where I live, every now and then we have a very brief power cut and then it goes back to Grid power. My Quattro detects this brief power cut and switches to Inverting Mode. Soon afterwards the Quattro switches back to Grid power.

I have my gas stove connected to ACOut2 so I can see if the clock goes off or starts flashing '12:00' after a proper power failure but this brief cut it doesn't, meaning the ACOut2 Relay assistant does not disable the relay when the brief power cut is detected.

My two assistants logic states (and also in this order):

Disable ACOutRelay2 when ACIn2 (Grid) Is Not Available for 0s.

Enable ACOutRelay2 when ACIn2 (Grid) Is Available for 30s.

Here is my question: Is there a time delay that an Assistant is triggered? Could the brief power cut be too short for the Assistant to run but be long enough for the Inverter to kick in and run from batteries? The reason I ask is that when in a high load situation with my Pool Pump, Geysers etc. running is around 6800W we had such a brief power cut and the system started to give overload warnings. Checking VRM it 'looks' like everything on ACOut1 and ACOut2 was powered from the batteries for a good couple of minutes and then the load on ACOut2 dropped off somehow. Is this at all possible? Should the Assistant not trigger at the same time the Inverter sees a power failure?

Hi,

I just finished an installation of three 5kVA Quattros in threephase configuration and a 380Ah AGM batterybank supervised by a Venus GX.

I'm using the Lynx shunt and PowerIn/Distribution.

When i configured the ESS to always keep batteries charged, one of the quattros started to make a strange noise. Is this normal behaviour or sould i be worried?

I would also like to know how to get the SOC visable in remote console, i believed the Lynx shunt would do this automatically, but it doesnt.

As of now i have ESS mode Optimized (with BatteryLife) configured and minimum SOC is 80%.

The LEDs that are on now is Mains On, Absorption and Inverter on, guess that is normal?

Kind Regards

My batteries in trailer RV are in boxes but are not sealed, will see road spray when traveling in wet conditions - is the Smart Sense waterproof?

Hi all

is there any way of altering or adding the resistance levels?

I have one sender in my water tank 0-190 ohm works perfectly albeit a little slow.

I also want to use one for my gas tank which has a 5-96 ohm range, id either like to add another resistance choice in the drop down or edit the American one to suit this sender as the Europe setting is right for my water tank sender.

Thanks

Mark
