Installing the Multiplus 3000

With a 50 amp electrical system in my RV, I'd like to install a Multiplus 3000 inverter/charger. I have three Battle Born LiPO4 batteries in parallel. My shore power is a 4-wire and there are two legs on the distribution panel. One of the companies that sells Victron adds a "Smart Phase Selector" in their 50 Amp RV upgrade. Can I install the Multiplus 3000 without this added device?Will the inverter/charger work in this regard?

Charging - Bulk, Absorption and Float

Hi All

Can someone help validate / correct my understanding on the above.

I am trying to understand in simple terms what is happening in these states of charge. I have read Energy Unlimited - and other documents - I think I've got my head around it - but fear I haven't understood it correctly. Be gentle with me if I am being stupid :-).

Bulk -

The charger throws amps in to the battery - as many as it can (while being limited by any specific limits set in the charger). As loads of amps pile in to the battery - the battery voltage rises. When the battery voltage reaches the specified absorption V - bulk stops - and absorption starts. This phase will simply go on as long as it takes - to get to the battery V to the set absorption V. This could take 1 minute, 1 hours, 3 hours....

Absorption -

The charger continues to throw amps at the battery - but in this phase it doesn't allow the voltage to go above the specified absorption V. So, as time goes on, in this phase, the number of Amps drop off, as the battery gets fuller, the charger requires less amps to maintain the battery at the specified V. Eventually the number of Amps being thrown at the battery drops to almost nothing - to hold the battery at the specified absorption V. At this stage, or, when hitting the time limit set for absorption, the charge stops absorption and switches to float. This phase will go on for as long as it takes, or, for a specified time if time limited in settings of any given charger.

Float -

The charger now just holds the battery at a lower specified voltage - trickling the lowest number of Amps in to the battery that it can- to maintain the float Voltage.

Feedback please - am I way off the mark ?

Welcome, please read the Victron Community Guidelines here first!

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, please keep your posts focused clearly on a single question, issue or problem.

If you have follow up questions that are different from the original, please create a new post. It is encouraged to create more posts with clear titles, if you have more questions.

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.


Accept the best answers

If you have asked a question, and an answer helps you towards a solution, please click the 'Accept' link under the answer.

Even if you didn't ask the original question, if you see or are helped by an answer on the site, you can also click to accept it as well. This will elevate the answer and help others who have the same issue.


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.


Helping Out

If you would like to help, there is a list of unanswered questions here and normally on the right hand side on desktop and down the bottom on mobile.


Many Answers

We hope that every question will receive an answer from the community. If you think you can clarify further, even if there is already an answer, please contribute. Other users are able to upvote better answers, or accept the best one (or more).

On occasion, a Victron person may also contribute. Please do not specifically @ request an answer from Victron without first giving the community an opportunity to answer.


Be Honest

We are all here to learn, please be honest with your level of experience and confidence. If you are certain of a solution and a fact, it is ok to say so. If you only think something might be some way, or are just testing an idea, please say that too.


When will new product X, Y or Z be available?

Please do not ask the community when products, updates or approvals will be ready or available.

New products are announced at various shows and on the Victron blog website. This is done when the specifications are quite certain, but before there is a good indication around supply dates. Delays can occur. Victron Professionals can subscribe to our weekly newsletter which provides updates.

Check the price list on our website. For soon-coming-but-not-yet-in-available products, it lists an indicative release date. Once in the price list, you can place an order with your distributors, and then you will be among the first to receive the product when it starts shipping. Anything not listed in the price list yet is not progressed far enough for us to give out a date. So we will not comment on availability questions.

Approvals are often subject to testing and 3rd party organisations that operate on their own timeline.

Thanks for your interest and patience, we want to have these available too!


More Technical than Business

As a manufacturer our focus is on supporting our equipment from a technical perspective, and rely upon a worldwide dealer network to reach customers.

If you feel very strongly about an experience you have had with a Victron dealer, and think that it is important that Victron knows about it, please direct it towards the appropriate regional sales manager instead of posting it on the community.

Please try and keep financial and business conversations direct with those involved and not on the Community site. Please do not post specific pricing, the internet is already exceptional for comparative price shopping. This community is not about that. The community can help with equipment issues, software bugs, and even feature requests but not finding the best deal, or getting a refund.


Questions about systems with Modifications and Customisations

Please ask any questions and information that involves anything that touches the ‘unsupported’ side of Victron equipment (such as custom programming, self-made cables, Raspberry Pi, modified hardware, APIs, Modbus TCP, NodeRed, ESS mode 2+3, etc) to the special MODIFICATIONS SPACE.

There you can find an active enthusiast community who are looking to make the most of their systems and expand their own knowledge and control beyond the bounds of what most normal users and installers expect (a nice stable and reliable power system).

This space is also for 3rd party battery BMS integrations that are NOT on the supported battery compatibility list.

Mixing lead acid and lithium

My Lead Acid OPzS battery bank is "becoming smaller" as I continue to load the system more an more. Initially I sized the system for 20% DoD, but now in next winter I am afraid it may reach 40 to 50% or even more.

I have now the chance to get a good priced set of Winston LiFePO4 90Ah cells and I was thinking to build a smaller independent system to offload some of the work of the main system.

I allways thought it would be not advisable to put lithium in parallel with lead acid, but the more I think of it, the less crazy it seems. My LA system is 24V based, the 8 cell Winston would be 25.6V nominal. I would source a 3rd party BMS to manage the lithium. Maybe the BMS can take care of the issues - disconnect in low and high side of the daily swings.

I actually have found a product to make hybrid battery banks (BOS - LE300) so maybe this isn't so crazy after all.

To install in parallel and monitor the 2 strings I was thinking if it would be possible to use a separate BMV on each string (Lithium and OPZS). Is this possible, using 2 BMVs on same Venus device?

Is this wiring diagram for a Lithium Camper scheme correct?


I am in the middle of making an elektrical schematic for on of my camperbuilds. In this build I would like to use an lithium battery.

I am using an Liontron 130Amp battery with build in BMS

Victron Smartsolar 100/20

Victron BVM 712 Smart

Victron Battery Protect 3 x

Votronic B2B charger

300 watt Solar panel

To protect the LifePo4 battery I am using 3 x an Battery Protect in this scheme.

My question is: is this overkill and if not are they in the correct position?

The Votronic B2B charger wich I am using is not working via an battery protect, because it has a build in safety system and it will cut of charging when the temperature or charging levels are getting to high.

Because I am not using an Victron battery :( I can't use an Victron BMS or Mini BMS or VE-BMS etc.


Now I found another build online, although this is not with an LiFEPo4 battery they are just using 1 battery protect. Mounted directly on the battery +30, I thought an battery protect could only work 1 way, so either charging or de-charging protection? Does this build on the picture below mounted correctly?


I am looking forward to an reaction! :)

Thank you, Maarten

Help me understand the stages of the SmartSolar MPPT?

I'm a newbie to the fancy Smart controller that Victron provides, and I wonder if my charger readings and settings make sense. I'm also not real clear as to how the specs that Crown Battery provides correspond to the settings that Victron requires in their VictronConnect app.

From having read others' experience, I believe I have the settings right, but I'd like to understand their actual meaning!

My setup:

2-100W 12V solar panels in series

Victron Smartsolar 75/15 MPPT Bluetooth controller

Victron BVM-712 battery monitor plus temp sensor

2 Crown 220Ah GC2 6V standard FLA batteries in series

temperature 7°C

This is my understanding of the "bulk-absorption-float" cycle, please advise if I have it wrong...

Charging starts in Bulk mode, with max available current (up to 50A per Crown, but in reality current is limited by my panels to @ 13.2A)

The starting ''Voltage" in Bulk mode is determined by battery state of charge - and it gradually climbs to "Charged" level, which is equivalent to Absorption level (14.22V per Crown specs).

Once the SOC climbs to the "Charged" (Absorption) voltage-level, the controller switches to Absorption mode, which then limits the voltage to no more than the Absorption setting, and varies the current, gradually lowering the current, as the battery becomes more charged (as the battery accepts less and less). Question: does the controller actually keep the voltage at the 'Absorption' voltage-level (Crown calls it: 'Constant Voltage') during this Absorption phase?

When the charge current drops as low as 5A (per Crown specs) the controller should switch to Float mode (Crown: 'constant current'), and (should?) holds the current at 5A, until SOC corresponds to (controller setting of) Float Voltage (13.5V)? Question: does the controller actually stop charging at this point? ie: No 'trickle charge'?

Obviously, this last is one of my stumbling points. If Absorption Voltage is constant at 14.22V, then when the charger switches to Float mode, the battery voltage will read 14.22, won't it? In which case, 'Float' voltage will read high at this transition point? Or does the Absorption charging voltage drop as the SOC gets closer to Float?

So my confusion comes from Crown specs being unclear to me, and names of 'phases' and specifications not corresponding between VictronConnect, and Crown, and the Victron controller not having specified a 'constant current' for the Float mode

As I said, I'm new at this, and my Victron controller readings aren't following my understanding of the way it should work. For example, during the controller's Absorption mode (set at 14.22V in the app), the voltage will read 13.55V at 1.7A, which seems more like a Float to me. It's a cloudy day, but it seems it could be charging at 14.22 at 1.6A, per the Absorption app-setting. Or is this possibly the temperature compensation?

Ii appreciate any clarity anyone can give me on this!

Connecting a charger to Load (Out) side of a BatteryProtect


I have two questions:

  1. is a BatteryProtect able to handle reverse current when connected as shown below in case of the BP220? Reverse current would be up to 30A while charging, and Vout >Vin.
  2. In case 1. is possible, let's now now assume the BP220 disconnects due to cell under voltage ( and thus BMS Load Disconnect output being set free floating). When connecting the charger (14.2 or 14.4V) thereafter, what would the voltage drop between Vout and Vin be? Can the BP220 handle 30A reverse current in that case, up to the point when it connects again after 30sec?

Note: the design intent of the layout below is to protect the SmartLithium battery from standby current drawn by the charger in case of cell under voltage. With the original design from the manual, this could only be achieved by a main switch (or pulling the fuse) between battery+ and BP. I cannot use a Cyrix-Li-Charge because my charger applies a IU1oU2oU3 charging characteristic with U3 being below the Cyrix-Li-Charge 13.7V engagement level.

Connecting Multiple Victron SmartSolar MPPT to one Battery Bank

We have a customer who currently has 2 x Victron Smart Solar MPPT Regulators... Both feeding a single battery bank - he also wants to now add a 3rd to the system feeding the same battery bank.

This is only a small system (e.g. MPPT100/15's) - and I know he could just get one large MPPT - however this is not the desired outcome due to different aspects / shading etc.


I have been searching and found that there are a few conversations similar to this however no rock solid answers so I have the questions:

1. Is the functionality available yet (July 2019) for the two (or 3) MPPT Regulators to work efficiently in parallel synchronising their charging algorithms rather than one switching off prematurely?

2. What information do the MPPT Regulators "share" with each other if connected via VE Direct Smart Network?

3. Will VE Direct Smart Network communicate exactly the same as using the Cable? Or are there limitations?

How do I know when my battery is fully charged? How does the MPPT know?

I have an Victron 150/45TR MPPT charge controller being fed by 600 watts of Renogy panels wired in series.

This is hooked up to two, wires in parallel Renogy 170ah lithium ion batteries.

According to their spec sheet they are "recommended" to be charged to 14.6 volts. I don't want to do that and would prefer charging to 14.2

Looking at the spec sheet, Renogy says the following.

Standard Charge shall consist of charging at 0.2C constant current rate until the battery reaches 14.6V. The battery shall then be charged at a constant voltage of 14.6V while tapering the charge current. Charging will terminate when the charging current has tapered to a 0.02CA. Charge Time is approximately b7 hours. Safe Charging consists of temperatures between 32 ºF and 113 ºF.

Does the battery stop accepting charge from the MPPT once the current has tapered? Does the MPPT know when to stop charging the battery? How do I know when these are full? How does the system know when these are full?

Lastly, what should my absorption voltage and time be? How about the float voltage? Battery University says these batteries should really just be charged in bulk phase to ~90 or 95% capacity and then turn off charging. What does the MPPT aim to charge these at during bulk phase? That doesn't seem to be a setting I can adjust.

Sorry for so many questions, this I am new to all this.

Thanks in advance!

BMV-712 Settings for Battle Born batteries

BMV-712 SOC is always wrong. 3 Battleborn Batteries.

Hello everyone. I sure this has been covered somewhere but I haven’t found the answer yet.

I have the BMV-712 smart monitor and it seems it’s never correct on the SOC. I have charged the batteries several times to full charge. During this process I run nothing off of them and charge them to the point it shows 0.2 Amps or less going into them and 14.4 volts. At that point I synchronize the BMV to 100%.

Now one would think the SOC would go up and down correctly with the voltage but the BMV-712 shows a low SOC all the time.

All of the settings are correct for the battleborn batteries firmware is up to date.





The system has 800 watts of solar and generator that can charge the battery bank.


One would think that when the system is charging and it’s only dumping in 10 amps via the generator it would show it’s nearly full on the SOC. But it always seems lower then expected.



So if anyone can please give me some ideas on what makes or ideas on what to change or make adjustments to I would appreciate It.

Thanks in advance. Crazy Marty.

PIN code when updating new blue smart charger

Not really a question but more of an update. Received a new unit and when I connected the Victron Connect app to it, it required an update from V2.11 to V3.00. Clicked "Continue" and was asked to input the device PIN number. The app suggested 0000 or 1234. Did this and the updated failed due to a failure to connect to the device. Ended up re setting the PIN code using the PUK code on the back of the device. The app confirmed that it had reset the PIN to 000000 - a six figure PIN. Just be aware it is a 6 figure PIN code in these new units, and you should use 000000 as the default and not just 0000 as that will fail.
