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 :-).
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....
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.
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 ?
hi, i would like to know if victron mppt charge controllers support wind turbines? if yes could i run 2 controllers in parallel, one with solar and one with a wind turbine?
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?
MK3 multiplus v5.8beta1., mac os VictronConnect. password ?
I’m trying to spec a system using all Victron kit and looking at the 100/30 MPPT charge controller. Does that controller accept 24 volts from solar panels and charge 12 volt batteries?
Hi all, does any body know if Victron have made stencils for Visio for their Victron Products?
Or if any body else made it and made it free to use.
It makes lite so much easier when making my schematics.
Can anyone kindly give me a straight forward explantion to what is the difference between Non-Isolated vs Isolated Orion-Tr. I am trying to regulate the current coming from the starter battery/alternator to charge my 720AH 12v battery bank. at the moment they are connected via VSR which is not healthy i think :)
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.
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.
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.
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.
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.
Occasionally Victron will edit questions, topics and answers if we think it will be helpful or add clarity.
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.
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.
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.
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.
I want to speak to the Manager!

PS - I also welcome any suggestions you might have. This is a live document, so there will be changes:
Having recently had a 4 x 100 Ah LiFePO4 system installed, I am finding hard to shake off the habits learned from a crappy lead acid system & allowing the state of charge to dip to 50% goes against the instincts learned from past experiences.
What am I safe to use out of these batteries?
Lots of hearsay, not too many hard facts.
They say that Lithium batteries don't need to be charged in absoption mode. I've heard that when charging Lithium you should go from Bulk straight to Float. Will setting the absorption time to zero achieve this? What about setting the absoption voltage to a really low voltage that is never achievable? What do others on this forum know of this? What settings do others use when charging their caravan Lithium battery? MPPT Bluesolar 100/30, Sentry 300AH Lithium, 300W solar.
I brought the 100/30 mppt charge controller wanting a full wiring diagram picture how to wire it up as I'm not sure. solar panels to unit to battery and do I need to put a fuse or circuit breaker somewhere what size if I do any help would be great thanks I have 1 300w solar panel and two 12v batteries
Any update on VE.Smart networking for the Orion Smart Tr DC to DC chargers? I'll have an MPPT and two 30A DC to DC chargers and it would be excellent if they all knew each other on the same battery bank.
[moderator's note: edited to show "VE.Smart Networking" rather than "VE.Bus Networking"]
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?
