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, 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?

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
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?
Hi, I've just connected a SmartSolar MPPT 100/20 (version 1.37 firmware) to a 12v 100AH Lithium Battery and can not find a battery setting to use.
I only have 4 presets (AGM spirel cell, Gel Victron deep discharge(1), Gel Victron deep discharge(2), & Gel Victrol long life (OPzV)
I have the latest Apple IOS, the latest IOS Victron app and connect via Bluetooth . I normally charge the battery from 240V AC with a Victron BlueSmart 30A charger set to Lithium with no problems
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.
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.
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.

Can I use my MPPT 75/15 solar controller as a dc/dc charger to charge from my alternator to my secondary deep cycle battery in my 4x4?
I have Victron SmartSolar MPPT 150/60-tr charge controllers connected to 6 West Marine AGM batteries (group 31, 105 amp hr) for a total of 630 amp hrs and was wondering what the charge settings would be on the controller. I noticed there isn't preset settings in the VictronConnect app.
Anyone else using a Tesla battery? I'm surprised to find that I can not turn on my inverter below 21.8V. Do I have to return this inverter?
The tesla battery is supposed to be 20% SOC at 19V, 100% SOC at 25V. Please help me utilize my full battery. Thanks.
It’s currently producing 17 volts but only 0.8amps ? Is this correct ? It does not charge my leisure battery very well
I have two questions:
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.
[image]Image: BatteryProtect Manual figure 5, modified (second BP out connected to 1st BP out instead of 1st BP in as in original diagram).
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 Multiplus 800VA
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
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!
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
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!
My victron mppt 100/50 in 12V mode says Nominal max is 700W, but down the bottom it says "If more PV power is connected, the controller will limit input power. "
What happens If I hook up 900Watts of solar to controller? & This is the full 900watts noon summertime.
Does it simple take in 700W & the rest is wasted/left? Will doing this damage the controller?
I've got a 12v 320Ah Narada Lead Carbon battery bank, a Multiplus 1200/12/50 and 3 SmartSolar MPPT 75/15's connected to 3 separate solar arrays.
The problem I'm having is the MPPT controllers tripping over each other going into float WAY too early. So on the daily chart I'll have one controller yielding as much as 1300Wh while the other two will yield as little as 200Wh each. At the end of the day the battery is not fully charged either.
The dominant controller can be any of the controllers on any given day. The wiring and settings are the same for all three controllers. I guess it just a software race condition which one detects the 1A float first. As soon as is does that 1A load goes to the remain controllers.
Is it possible to have them share better. Does the BMV or Smart Sense Synchronise them at all. As it is they are operating at about 30% efficiency once two drop out.
Seems that only one MPPT controller can be the only charge source in the circuit. Otherwise once any one hits the 1A float threshold it go to sleep and doesn't wake up again. Leaving just one controller to do all the work and the battery no where near charged.
The situation is exacerbated as the Muliplus charger starts up when the generator is fired up. All the MPPT go to sleep because the generator is providing all the charge current. Then when it is turned off often only one charge controller comes back to charge and the other two stay on float even though the battery might only be 30% charged because the float voltage being reached does not wake them all up.
These MPPT charge controllers do not play at all well with other charge sources. Including their own kind. Is there any way to have them act as a simple power supply? That is just providing a voltage to battery and allowing the battery to simply absorb what it can? Or maybe get rid of the 1A threshold or have a timer that checks periodically if the battery can now accept greater than 1A and go back to absorption.
Basically modify the algorithm somehow so they're get back to work when they can. At the moment it's like having an employee that gets things done in the morning then goes to sleep and doesn't bother checking if more work has arrived because the other bloke is doing it all by himself and struggling at it as a result.
Seems theses things are too smart for their own goodand as a result are constantly tripping over each other. After which they don't get up and back to work again for the rest of the day! If it was an employee you'd fire them for not being team players! Lol
Is it possible for me to just move the charge leads from the battery connector to the output connector? If the MPPT can output 15A at say the float setpoint voltage to the output without a battery in the battery connection then that would be better charge controller than all the current "smarts" before the battery connection terminals!
Any solution would be appreciated.
Does anyone know if there is a comparison paper or chart for the BMV lineup? After getting the Raspberry Pi working with my current Victron Controllers I am considering switching from a Bogart Trimetric to the BMV to have that info included in VRM too. I guess hearing that should make Victron happy...
I ran the math with the max panel voltage of 18.4v and a 25% safety margin and it looks like it should be okay. I wanted to get real world input. My RV forum is saying I should run a 30 amp controller to handle 2, 100 watt panels in parallel. One will be fixed on the roof, and I'll eventually buy a portable to hook up to it.
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.
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.
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!
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?
I have a 6ooAh AGM batt bank on a sailing boat (3 x 200Ah)
What is the max safe current drain for said bank, especially with longevity in mind?
I have a 1,6kW 230V AC watermaker and would like to run it off the batt bank through an inverter for about 30min at a time. (and some other power tools on the odd occasion)
I do have a generator so that watermaker can be run for longer periods but for 30min (making 50L of water), it would be very convenient to not use the generator, not to mention saving petrol, fumes, and noise.
I have 640W solar and 300W wind gen which should be more than enough to deal with the discharge, I believe, on a sunny day.
So, is there a rule of thumb for a max safe discharge current for (AGM in my case) Lead Acid Batteries?
My gut feeling is that 300A for an hour on a 600Ah bank should be safe. But then my 2nd gut will freak out when it sees 200A of discharge on the BMV.. Even 100A is a hell of a lot in my mind.
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 :)
