- In this short video, Johannes from Victron Energy answers a couple of questions that we collected from different platforms (Victron Community, email, social media, etc).
Subjects in this episode:
What are the advantages/disadvantages of using either the VE.direct or VE.Can communication?
Why do you guys have the BMS outside the battery?
I wonder if you could explain the connections to "Ground" in a mobile application.
How does actually a Cyrix Battery Combiner Actually work?
Why does a Multiplus II 3000/24v need a 5kw generator to charge the batteries?

Do you plan to build an Orion-Tr Smart 12/12-50, e.g. with 50A like the competition offers them? Would be greatly appreciated :)
there will be more models , yes !
I have some questions about the Victron 10kva Automatic Transfer Switch (ATS). I see that there is an ability to connect the ATS to other Victron devices. What is the benefit of making that connection, and what does one use for cabling? We had the ATS professionally installed today and it's working very well!
Hi graham, i am not sure what you mean by connect to another device, like in parallel or such?
According to the datasheet for the Victron Peak Power Battery with a capacity of 20Ah, it specifies a continuous output current of 30A from Output 2 and a nominal voltage of 12.8V. However, if the logic board consumes 12.8V at 14.7A, it is unclear if the battery will supply more current than the specified 14.7A to the logic board.! any tip is appreciated
you dont use the main output of the PPP?
Official question to Victron Energy for the next video:
Why doesn't Victron Energy provide a BMS for third party batteries?
I will answer this in Episode 6 then ! good one, for now, the combi BMS/battery is essential to have a energy system work well and safe. We don't want to have the responsibility of a complete battery system when we have no idea what/how the batterie is built.
Good video - now I have to go back and watch 1,2,3 and 4m :) The audio was excellent thru my WYZE BT headsets. The speech was a little fast for me but still ok.
i will slow down next time ! ;-)
Will victron ever build a solar inverter with batteryless ability, providing useable ac power as ive seen with other solar inverters and diyers.
i don't think so.
Thank you for answering my question.
Can you also tell me how to properly connect the inverter to the battery protect remote terminals.
Thank you.
depends on the inverter model you have , if a simple plus is needed for on.off, then there is were the BP is connected, otherwise a relay or such may be needed.
@@johannesboonstra6917 That is what I thought. Thank you.
Johannes is my hero! What a great video series!
Thank you for doing these!
Please describe how to connect a dump load to a small or mid size mppt controller. Can a purely resistive dump load be driven in a pwm fashion? Many of us want to use excess solar to heat water without disturbing our charging (bulk, absorption, float) routine. Thanks.
the MPPT and Cerbo are only able to switch on/off, not on a PWM signal I am afraid.
Thanks Johannes,
I have a question for your next video:
I'm building the electrical system for my campervan using the Victron product line.
I have a Multiplus 3000, SmartShunt, Cerbo GX, Buck Boost, Lynx distributor and two 12V 200Ah Smart Lithium batteries connected in parallel.
Additionally, I also have a spare 12V 100Ah Smart Lithium battery I would like to be able to use.
Due to the different capacities, it's not recommended to simply add this battery in parallel to the others, but is there another way/product that would allow me to add it to the system so I effectively have 500Ah available?
You want to wait for the answer in the episode 6 ? ;-)
@@johannesboonstra6917 I don’t mind waiting until the next episode (maybe more people want to know this), but if you can already answer here that’s even better of course! ;-) Thanks!
Where can I get this "I ❤ Victron Energy" Sticker from the Back off the Laptop?
I rewatched the section on connecting the shunt to ground 4 times and I still have no clue what you’re talking about. Does it connect to the chassis or not? Does the neutral or negative AC connect to ground, which is it?
Between the battery minus and the shunt the chassis may NOT be connected, on the load side it’s fine to connect the chassis . Ac grounding has nothing to do with the dc battery monitoring
My electrical cabinet is metal. Is the BT module and associated antenna on the BMV-712 situated at the shunt or the display unit?
Thats in the display.
I have a question concerning Multiplus installation. I want the Multiplus 12/1600/70 in my ducato camper van. I wonder about the RCD (earth leakage circuit breaker/aardlekschakelaar). When using the inverter a reference to ground is lacking. Does this mean that using the inverter must work without this protection? Should I implement another safety measure?
No, there is a contacted in the Multi which joins the PE with the inverter Neutral when in inverter mode so the RCD remains to work as intended.
@@johannesboonstra6917 so the rcd will work under the condition that the mp is properly connected to the vehicle mass. Right?
@@ceesmidden yes, and/or the battery minus is on the chassis as well of course
@@johannesboonstra6917 thanks!
Thanks for posting these videos. I could watch one every week. A question about my Orion: Is there a good way to allow for my house batteries to charge my van battery if it were to ever be drained? I also have a Victron MPPT. Both of those are feeding into the lithium house batteries. Thanks.
Thanks! Q: the Orion could be switched (as leaving it on the housebatery would be drained) to feed the starter battery. This switch can be on inout voltage (So ON when the is a charge voltage on the household bank) or manual
@@johannesboonstra6917 Thanks, so in this case, the Orion is just connecting the two batteries and the AGM starter battery will start charging from the lithium house battery? It's that simple? Any way to know what the rate of charge would be? The lithiums normally reside at around 13.75V. 800 amp bank.
And I'm assuming it would be a bad idea to try to crank the engine while this is connected this way? I can't imagine the Orion could handle that much current.
@@moneypitvan6378 the Orion doesn’t provide more then able, so there would be no issue
Questions for Victron:
1) On your next video, Can you please show us a Multiplus 24V/3000VA/120VAC side by side a Quattro 24V/5000VA/120VAC so we could get a feel of how bigger is the Quattro? and please tell us the dimensions differences in inches.
2) Am I correct that 2 of your future 24v MultiPlus-II 2x 120/240VAC working together can pass through split phase and each can use available 120VACx50A on each phase of shore power to charge the batteries (doubling the charge current when compared with only one multiplus) and produce split phase 240VAC off batteries when disconnected from shore power? Am I correct that the same can be currently achieved by using two Multiplus 24V/3000VA/120VAC?
? 1. Please have a look at the datasheet for this, that should give you enough info. 2. the point of the Multi 2x120V is that you don't need two units to be able to use 50A shore connections/splitpfase. When you building a system with two units, there is no need to go for the 2 x120Vac models as you can simply configure them in split phase.
@@johannesboonstra6917 any plan to produce MultiPlus-II 24V/3000VA/120VAC for north America? its dimensions (smaller depth) better suits my application.
@@The_Zeroth yes !!
@@johannesboonstra6917 can you give us an availability estimate?
@@The_Zeroth that’s most likely 4 - 7 months from now , but this is not certain!
These are great video. Much appreciated. Thank you. I'm planning a system for my boat with the MultiPlus-II 2x 120V. The system I'm replacing is 3 years old and the terminals have signs of corrosion. Do you recommend any spray sealants to protect the terminal from the humidity of a marine environment?
No, we already coated the PCB's o that's taken care of. If you clean the connections well during installation there is no need for extra spray or such.
Love the wall behind you. Does Victron have surplus/demo sales page?
No, we don't have these as manufacturer as wel sell through distributers only. You could try there.
You guys need to start doing more 48v stuff! Electric propulsion is on the up!
More ? ;-) , we already have wide range on inverters, charger and charger/inverters. But we are expanding the 48V as well as beside propulsion also on off grid systems there is a huge demand.
@@johannesboonstra6917 what would be really useful would be a basic victron how it works page, I'm happy to do the training. But for your average punter it's hard work to know what can do what and how (think teaching your grandma snapchat)
I'm still learning your kit and I like it, but it's not easy to navigate for somone still learning (without the training)
Love the how too videos!
This is about low voltage protect
I've just purchased 4 Victron 100ah super cycle batteries and a Victron 220ah battery protect, I am very confused about the low voltage disconnect.
in previous videos I saw that the low voltage disconnect is set to disconnect when the voltage reaches 11.8, everywhere I've read says that a 12v battery is 50% discharged when is gets to 12.2, so why is the battery disconnect set to a much lower value, please explain why the disconnect is set to lower than that 50% value.
My assumption is that the disconnect low voltage is the voltage while under load and when the load is shut off then the battery voltage will rise to it's no load value, please please explain, I'm afraid I will destroy my new batteries that I paid a lot of money for.
Good question ! I will explain more in the next episode (after the one which is already recorded), the major point is that a battery will "recover" its voltage after being discharged. So if you would draw 25A from you battery the voltage would drop to lets say 11,5V after a certain time, indicating to you the battery is extremely empty. When you then stop discharging you will see that the voltage will go up again and land somewhere at 12,4Vdc, If you would this with a 2A discharge the battery will not recover and the battery is actually therefore much further discharged. So with a big current after all the battery wasn't that empty, at a low discharge the battery is extremely empty. A battery protect is therefore allowing the battery to discharge with a high current. If your discharge is low (compared to the capacity of the battery, the cur of voltage needs to be set higher)
@@johannesboonstra6917 Thanks for trying to explain, I'm very much looking forward to the next video. I'm not sure anyone out there on the internet who is into green energy and battery management really understands this subject totally(with the exception of the experts like yourself) I've asked similar questions to suppliers of batteries etc. etc. but only get answers that are more confusing. Maybe the problem is that it seems like a simple problem but battery voltage under load and under NO load are very different things. Of all the research and videos I've watched over many years no one ever explains the load and no load voltage difference.
Do you plan to do a charge controller for wind turbines? Living in Scotland we get plenty of wind and usually not so much solar especially in winter, maybe unbraked for VAWT and braked for HAWT, alternatively could a Smart Solar controller be used for VAWT?
No sorry, that market is too fragmented and small I am afraid.
I have the Orion Smart-Tr 12 12-30 in my camper van.
If I fit a 13.8V mains switch mode power supply to the starter battery, would the Orion be able to manage charging to the aux battery when I am hooked up to shore power?
yes , most likely it will. if the power supply is powerful enough
Re episode 4 Question 1: I have the 12 | 1600 | 70-16 230V MPPT 100 | 50 Easy solar, where is the trickle charge connection for the starter battery? The manual states at 4.4 to refer to appendix 1, however there are only appendices A-D! and none of them refer to the trickle charge connection.
It located at the connection board , its a faston connection.
Why does my Multiplus II 3000 12V 120/240 continue to charge my batteries below the 5 degrees Celsius threshold as explained in the Victron Connect App? I have two Multiplus inverters delivering split phase both with temperature probes installed and verified working. My batteries have internal BMS but do not have low temperature cut-off, so I really need the Multiplus to do it’s job here.
The Multi doesn't have this limitation, this needs to come from the battery (or an external temp sensor which is sending an open/close contact to the charger or heating source).
Hi Johannes! Does the Trickle Charger of the Multiplus has a built-in diode, to prevent it from current flowing back if the voltage is higher in the starter batterie?
Why is it charging, even the multiplus is off?
Thank you!
Well as it is a diode (limited by an NTC) the current will also flow when the voltage of the main battery is simply higher then the starter battery. Reverse current should not happen, then there is a hardware (diode) failure
Hello am new to Victron and was looking to buy mppt from you,what's the differences between bluesolar mppt and smartsolar mppt,smartsolar a good choice?
Smart solar adda Bluetooth capability!
I'd like to see victron build a BMS for batteries other than victron's lithium batteries for people like myself who builds their own battery banks using nothing but raw lithium cells . That would complete you ! lol Just a thought . I'm a huge fan of all victron's equipment. I used to have an aims inverter , But after looking into and then testing victron's equipment , I have upgraded my entire system to all victron , with the single one and only piece ,... The BMS !
Yes, I believe you would but as you know the BMS is critical for having a safe/reliable lithium system and is more then just a add on to a couple off cells. There we have chosen to not be a part of a DIY battery system. We truly believe that in the end you are better of buying a complete Victron battery kit (yes I know the initial investment is higher) which is designed to work and gives maximal safety, reliabilities
and features which even overlap with other system components.
@@johannesboonstra6917 A DIY battery bank can be built to be just as safe and reliable as any company brand manufactured battery . There's no doubt victron builds a great product , I dare say even the best on the market today ! But its blatantly obvious monopoly dictates !
In many places in North America and Europe, winter temperatures drop below -20C, at least for short periods. My needed low temperature operating limit is -30C. Most of your equipment is rated at only -20C. Do you foresee any problems with storing or operating your equipment at -30C, particularly the DC to DC converters?
no, that will be fine. But (rubber) can become less flexible and can even break , so when installed its fine.
Quick question: Is the AC input on the MultiPlus-II bidirectional ?
Yes sure, in fact the major design goal for the Multi II was to have it optimized for ESS
Should I connect the ground-connector located bottom left of my MultiPlus 12/1600/70-16 to my gound/zinkanode of my sailing yacht or leave it not-connected.
all metals on board needs to be joined, so yes the Multi needs to be grounded on the central grounding point
@@johannesboonstra6917 thanks, then I connect my Multi with the earth-pole (zinkanode), thanks for quick reply!
Hi thanks for the reply I apologise for my lack of knowledge on this subject but wondered if you could explain what that means do I have to do anything or does the victron smart look after everything and one other thing do I need to alter any settings in the app? Kind regards Don
What what means ?
I am building a system using the Lynx component along with the Orion alternator charger and Victron MPPT. I am using 300-400aH of Lithiium. I would like to switch the power coming in from the Orion and the MPPT to charge a 12V 300Watt DC water heater to heat up 20-25 Litres of water in an ISOtherm water tank. How can I do that? What components would I need to add? Thank you for these videos.!
The switching should be done with something which knows when to switch, so a battery monitor or a Multi in the system perhaps.
Any thoughts on a 24v 5000 Multiplus II 2 x 120v in the series...with RVs getting bigger and bigger the electrical demand also increases!
I hope you mean parallel?, well you can have two regular multis in parallel en create a split phase from them, then there is even 120/240Vac in inverter mode. Plus you have double power of course.
Sorry I editted my comment without deleting parts...wandering if you are looking at making a 24v 5000w Multiplus II 2 x 120v...similar to the 3000w one you just talked about in this video.
sort of the same questions as stated below except I am interested if you will be marketing EasySolar 24/3000/70-50 MPPT150/70 for 120V US market any time soon.
there happen to be plans, yes ! timeframe, I guess I about a year from now.
We have a system design with four separate PV arrays. These will see different sunlight level due to their position. Our design is to have a separate MTTP for each array. These will then be connected with Ve.CAN. Will this sync the battery charge stage but allow each array to find it's own MTTP?
Yes,! that's the great thing on paralleling MPPT charge controllers.
@@johannesboonstra6917 yeah just sanity checking. Thanks for the reply.
THe Lynx Smart BMS looks awesome, will you provide an BMS for 4S 3.2V cells as well?
the Smart lynx BMS is also for (our) 12,8Vdc batteries indeed. not for third party batteries
@@johannesboonstra6917 can you recommend any good BMS with Victron-support?
@@tomashermansson6898 I can’t point out to one , but have a read at the community page of victron
Lots of similar setups are discussed there
Last week A Multiplus 12/1600/70 has been installed in my Ducato van by my dealer. I worry a bit about how this was done. As it seems my dealer has applied a socalled IT net. The MP is not connected to earth and the ac out is not connected to a rcd. A rcd has no function anymore. In case of a device issue (but only one) in no current can leak to earth, which protects the user. I noticed that rcd is also not working when the van is connected to mains (230v). Does not feel comfortable to me. The manual instruction of the multiplus is to connect the mp to earth through the chassis of the van, which allows the rcd to work also when disconnected from mains.
I look forward to your advice.
I think this discussion should be done with the installer or have a second opinion from another installer. In general the PE terminal needs to be connected to the chassis, the Minus of the battery as wel. The ground relay needs to be active so that RCD work under every circumstances
Hi, Thanks for your valuable information.
I'm setting up a 48v battery system in a trailer building that will I use for catering remote bus tours in Australia. The fridge I'm building is 300l, I'm using an Ozfridge eutectic system. My issue is that the fridge has an eco setting, what this does is it senses the voltage and when the voltage rises above 13.5v the electronics tell the compressor to run until it reaches the end of the cooling cycle. The theory behind this is that when there is excess power. (the batteries are neary fully charged) the fridge runs and stores energy in it's eutectic tank while there is excess solar instead of using the power from the batteries when there is no solar.
My question is does the output voltage from your Tr 48-12 DC to DC converter vary as the input input voltage rises as the battery levels come up while charging. If this was the case I though I could set the voltage on the converter at a point that it raises to the 13.5v when the batteries are at a certain voltage in the charge cycle. Will this work?
Thanks Robert
the Orion has a fixed output voltage
You state: “this year”… but the video doesn’t show what date was made
the video is from 2021
Thanks very much for answering.
It may be usefull to add a date to each and all videos as standard 😀
Thanks for your teachings !
Another question: Where can I get that sticker that's on the laptop? I've got all my Victron gear in a 1971 Volkswagen bus :D
Haha, That was made as test, I can see if there are any left. drop me a mail at sales@vcitronenergy.com as reminder and I will let you know!
Thanks for answering my question, Johannes! One other question, I have ordered 2 VE.bus BMSs now from two distributors. Both have some issue with the pin connections not holding well. Ostensibly, the distributors are in contact with Victron but I'm wondering if there is a workaround in the meantime. Can you demonstrate inserting a wire into the pin connector and giving it a tug so I know how firm the connection is designed to be? Many thanks.
? well if the pin is long enough you cannot remove it (with normal strength ) from the terminal. Did you tru a longer version then you are using now?
@@johannesboonstra6917 I tried two lengths of ferrules in sizes ranging from 18-14 AWG, all with a hexagonal crimp. Only a long bare wire (~14mm) would have any holding power, but even then it could be pulled out with little resistance. I suppose the wires could be permanently secured with a little hot glue, right?
@@_r_ma_ glue isn’t a good idea
Please try a longer crimp

Hi, i have a Solaredge SE10K-RWS with BYD LVS 12kWh. Now i try to find out, how to get off grid function. In all example configurations there was no batterie connected to the solar-inverter. Does that work to? Can the BYD LVS be connected to the solaredge inverter and the three Multiplus II at the same time so that the Multiplus will only discharge in case off grid failure or du i need a second batterie (or connect the battery only to Multiplus)? Are 3000W ok or 5000W Multiplus necessary? I could accept lower power in case of grid failure.
There can be an off grid system made with these components , your dealer can inform about all details. Doing off grid with MPPT charger controllers makes more sense though.
I am working on a D.I.Y. Victron expander that takes VE.direct from my BMV-712 and provide additional independently programmable relay outputs. Is there a way for me to get details about the BMV-712 Blue Tooth protocol? I am an EE and design wireless interfaced instruments in my day job. I would be willing to sign a non-disclosure agreement.
Sorry, these are not open source at the moment
I have a victron 12v 30a DC to DC charger. What fuse or circuit breaker do I need before it and what size do I need after it? It will be hooked up to starter battery and then to lithium battery bank in trailer. From research I have heard a 50A before the charger and a 40A after the charger. Is that correct?
hello, 40A on both sides should be OK.

I have a twin engine launch with 90 amp alternators each has a three output Studer battery isolator, one from each engine is connected to an AGM 12 volt 580amp house battery. What device can I use to regulate the charge from the alternators to an AGM battery to avoid overcharging.
Well there isn’t really a regulation needed if you ask me , but a buckboost converter could be used to limit current and set a charge voltage
Nice blue boxes 👍🥸
i am looking at upgrading to victron for my microgrid setup. i currently use the utility supply only when no solar or battery storage is available which of your inverter/chargers supports the use of utility power as a back up to an off grid type system. i would need 10kva capacity? thanks
all charger/inverters can be used for these systems. Important is that also your pv inverters are able to switch off/on/throttle down on frequency change.
@@johannesboonstra6917 thank you Johannes. Finally in this setup will the inverter automatically switch to grid upon loss of solar or battery. Or would i need to provide a contactor to bring in the supply similarly to starting a generator?
Hi Johannes, here in Australia,
In my car I have a lithium auxiliary battery to run a fridge, and a lead acid for the car, can I charge both batteries together with my installed IP22 charger 240 vac
best is not to do this as the absorption time for lithium is far less then needed for your lead battery. if its only for maintain ace charge you could however.
Dear Victron, Could you please add a ‘lock layout’ button on my VRM page. I view it on my iPad and keep on accidentally messing up the layout when I scroll down. Big thankyou in advance.
good comment! I will forward this!
Can you split phase a multi 24v 3000 and a multi 24v 2000 or do they have to be the same?
No, for paralleling ect the units needs to be 100% equal
I have what looks like an old Skylla TG24/100 WHITE charger. It has two identical boards with their own inputs and outputs. Are these independent and how should I wire it up?
hello, the manual is found on the website under old manuals.
Could please you do a tutorial on AC Coupling.
Ye si can put that on the list ! there is also this already www.victronenergy.com/live/ac_coupling:start
which energy meter do i use when i connect 12 x 15kva multiplus 2, and split them 4 in parallel. please assist because the ET340 can measure 65A per phase. estimated current per phase will be 200A per phase
If the grid I more powerful then what the meter can handle the only option is to have the inverters inline with the AC source so a meter isnt needed then. PS there will be meters capable for more current in the future
Victron Energy MultiPlus 24/5000/120-100 - 230V VE.Bus Inverter/Charger can this unit be configure to output 120V with the MK3-USB driver on a computer? if not dose victron carry a stepdown 220v-120V?
No, the hardware is determining if a unit is 230Vac or 120Vac, this cannot be altered later I am afraid.
Hello Johannes, Thanks for these tech talks - very useful. I am currently using Victron eqpt on all my new projects and intend to migrate en existing project from another (dutch) compaies products to yours. Thanks for supporting Open Source :). My question is this. I have a system witha Multiplus II (12/3000), SmartSolar, Orion-Tr Smart
12/24-15A (360W), and 100A Smart Batteryportect, Orion-Tr 24/12-30A (360W) all of which support remote on/off. However, the Smart Battery Protect also documents either pulling up (to system voltage) or down to GND as a switching method. Do the other products also support this but it is undocumented? Many thanks.
All units which have a terminal block indicating a H / L will have this feature.
@@johannesboonstra6917 Wonderful - thank you
1. Is there _any way_ (with external equipment for example) to current limit the power draw of the Orion-Tr Smart (12|12-18 in my case)? I've got it hooked up to a fairly old 51A alternator and in good conditions it can pull 25A which feels like a little more than the alternator is really made for given that the car itself is pulling a fair share as well.
2. If not, will hooking up a remote switch and only have it switch on during high RPMs for short periods to avoid overheating work? Or does it still pull power when off and only the output is disabled?
3. Can you make a smaller one (or add current limiting via software?) for us with teeny alternators? 😇
Q1 no , I am afraid there is no current setting possible. then a buck boost converter would be the solution here.
Q2 Yes, if you are able to switch on rpm that would work!
@@johannesboonstra6917 Thank you for your answer! Do you mean a buck boost _instead_ of the Orion, or between the Orion and the alternator somehow?

Hi. If all things were equal, one 400w panel or 2 x 200w panel? (or 4x100w panel)
Same thing? or is there a benefit of either?
Thanks.
well with the smaller panels you can get a higher PV voltage, so less current and less losses and above all a MPPT charge controller which starts charging sooner in the morning.....so my advise is go for the 2x or 4x is serial...
Johannes Boonstra is there a limit on how high you should go in Volt in an small 4 panel installation?
I buil one right now and connected 4 panels: 2serial and those 2 strings in parallel.
My voltage is at 74V at full sun.
I want to connect it to your mppt 100/50 and feed it into 4 batterys (24V system) and the 24/1200/25 inverter.
Should i connect them all in serial (140V) and use another mppt that can handle this voltage?
what would be the best victron charger to use when having a backup 230V 3KW input ( V2L from a EV), 48V 3Phase ESS setup in use

Hi, question to MultiPlus II, do you have plan to make more compatible PV inverters profiles, like it is made for Fronius PV inverter? (PV power reduction functionality)
The profile can be configured to basically any pv inverter there is, did you knew that?. Beside this the idea we have is that more and more PV inverters will be controlled digitally using CAN or LAN connection.
@@johannesboonstra6917 I have PV microinverters on the roof and I just looking now for solution to make it "a live" during blackout. I was watching video where MultiPlus II was controling nicely Fronius inverter (by frequency shifting?) but other PV inverter just switch off during frequency increasing. So actually my main question is what norm should fulfill PV inverter to be that nicely controlled like Fronius inverter?
My microinverter is DEYE SUN 1300G2 and, according manual, have possibility to reduce power with LFSM-O threshold 50,2Hz and with 5% drop, max frequency is 52Hz.

Hi. I've got a multiplus 5kva inverter with no grid available, so a generator is being used as ac input if needed and charge batteries. Ups mode is off and in charging weak ac input is activated. What happens when starting the generator it will start charging and after 10sec go to pass through and stop using generator source and start charging again. It will continue doing this and not stay constant, generator isn't been overloaded and voltage stays between 219v and 225v ac. Am I missing something.
First, switch OFF weak AC input as that's not needed to be on, this will limit the charger. wide freq range ON. Make sure the Maximal AC input current is set to 75% of the Nominal generator power. AC input voltage window 210-240Vac. Would like to hear the results then.
Thank you Johannes. I'll do so and give feedback

Hi We are designing a system with a Cerbo GX as the system controller. Can we use an existing HDMI touch screen with Cerbo GX or do we need the Touch 50. Also can the brightness ne set very low on the Touch 50 to save power? Many thanks Andy

I got a real dumb question, getting ready to mount my victron 712, first time ever dealt with this type of battery monitor, shunt, I need my negative input to of shunt to be on right side looking at the shunt, so I can minimize the length of battery cable coming to the shunt and not have to loop back a battery cable to my negative busbar, can the shunt be turned around any which way and mounted, like I said that's a dumb question but I've got to ask
no, you have to stick to the battery/load ends to have the shunt work well.
So the shunt has to be mounted horizontal , it can't be vertical and can't be mounted upside down and still run the battery cables to the appropriate sides
Yep like I told you it's a dumb question and I appreciate your answer, so let me try to put this a different way. I'm standing at a wall I'm going to mount the shunt right in front of me on the wall, does it matter with the RJ12 connection is pointing upward or downwards, I understand the negatives need to be at the proper connections on the shunt from the battery and the load.

@@johannesboonstra6917 I purchased from Amazon and different businesses. Victron is very expensive and should have a customer service team to help out.
Maybe this is something you could cover in a video or maybe with an answer here, I asked a question already and I just discovered something I never mentioned in my earlier comment
I just found out that you can't use a battery protect with an inverter, I have 4 100ah Victron super cycle batteries, a 220 Victron amp battery protect and a Victron 2000va inverter, do I just wire the inverter directly to the batteries and the battery protect after the inverter so the inverters power is not measured through the battery protect? is there anyway to show me a diagram?
for context, I also have 12v direct loads, couple of water pumps and a UV light, is it safe to use the battery protect after the inverter has already had a supply from a bus bar and the direct loads on another post of the bus bar? so the battery protect will not have it's power supply controlled by the battery protect.
There is hardly a point in having the Battery Protect inline with the inverter has the ability to switch on low voltage itself, So make the setting there. Then you won't be needed a high powered model either. The 12V DC loads only travel through the BP. The Battery Protect has a short circuit detection which works perfectly, but not when having loads with capacitors (as these are short circuits at startup as well).
I have a quattro 24v 5000. I when I plug into 50a no problems. But when I plug into 20a it pops the circuit breaker even after I tell the quattro to use 20a. Can you please show me the correct way to adjust my quattro to charge from 20a.
is this a 230 or 120Vac model? there is a minimal AC power needed to be able to be used by the Quattro. If the AC connection is (far) less then the minimal value you could try the [charger only] option. The 120V model does had a decrease of input limit after version xxyy423, so perhaps looking at that might help as well.
@@johannesboonstra6917 I have the 120v . I'll have to get back to you with a serial number to know more. I was able the program it to lower amperage using your cable and setting it to accept remote.

I have two victron IC 3000 in parallel with a 1200AH lithium bank on my boat. When the bank goes into bulk charge it's a struggle for the genset to provide the 3kws the ICs want to get the bank back to absorb or float and still have enough power leftover to run the ACs and watermaker. How can I reduce the bulk demand? The solar and wind generators will bring the bank back to float given enough time so I don't need the genset to struggle do get the bank up in less than an hour. Please let me know ty!
There is the AC input current limit, set that to about 70-80% of the max of the generator and the charge will throttle down when there is AC load coming in.
What Victron product allows a 100w solar panel to charge a 48v battery bank?
wow, missed this one. sorry. the problem with MPPT inverters is that they don't boost the voltage , so as long as the pv voltage is higher then the battery voltage it will work , otherwise, you need more panels in serial connection.
@@johannesboonstra6917 that’s what I figured. I wish they made a small boost mppt controller so I could charge my 48v bank and not worry about shading over my series strings.

Is there a marine Victron inverter which can supply both 120 VAC 60 Hz and 220 VAC 50 Hz concurrently, using the house batteries or whichever shore connection it may have available?

Now I want to cut off the alternator from sending current once the battery is full. So once the battery is full the internal BMS should stop accepting charge/shut down I imagine so once that happens I want it to signal the alternator to also stop.

Can you please give some assistance to how I can get the HDMI cable end repaired with a wiring diagram. Unfortunately my local Victron supplier only has an option to replace the whole touch unit and not fix the HDMI. Very upsetting for a very expensive product.

Hi
I got a shock when the battery temp recorded by my easysolar hit 35C. Digging through the community site I found it's not uncommon for the temp sensor to be a long way out. I also found that Venus OS has a screen to correct/compensate for sensor errors. However this doesn't seem to be present on the ccgx. Since finding the high temp, I've been monitoring by checking the battery terminal temp with an IR thermometer. The temp reported in the Victron setup is consistently close to 5C higher than the measured value. I'm assuming that reported temp is terminal temp. It also seems that the solar side is not temperature controlled, only the mains charger.
So a couple of requests.
Please give us one of your excellent tech overviews on how the temperature sensing works/fits together.
Explain how to calibrate the sensors in the software.
Thanks.
The solar chargers can als use a temp sensor, but then the bluetooth smart battery sense ones. CCGX runs on the Venus OS, so there is no difference in settings there I am afraid by the way. its indeed reporting the clamp temp as it is doing the measuring there. How sensing work will be done in the next episode!

Can you tell me the correct param to set in the Cerbo GX? I have solar power peaks of 14 kW and the battery should be charged slower. The sureplus should go to the grid. There is also a 4 kWp Fronius inverter connected to AC out of the Multiplus.
limiting current is done with DVCC , then the total is limited, this requires to have a Cerbo in the system though but that's what you have.
