Is Victron going to release higher power Multiplus-II and Quattro-II around 8kW, (or similar steps to old Quattro’s) I’m in US and really like the modularity, but the setup for 12kW split phase is… awkward… 4x Quattro-II 5kw’s instead of 2x Quattro-ii 8kW. Also, if running split phase,and two connected inverters, is the pass through for 240v 10kW or less? And the 120v legs… I’m assuming both legs each are capped below 5kW until you have 4x?
Hi great videos very informative, I have a 12 - 12 -30 B2B fitted in my van conversion, please could you consider an update hopefully to firmware that allows a B2B charger to work in both directions so that it chargers a leisure battery but will keep the van battery charged if the vehicle is left for a long period of time and the van battery is full. The system has 600w of solar, 300amps of lithium and 100/ 50 MPPT charger? Many thanks
There will be a model range for this shortly , but working on 800Vdc, the other models remain single phase with the option to create any system needed.
Hi, Johannes. I have four Smartsolar MPPT 250/85 VE CAN units. Once my batteries have charged and the MPPTs are only supplying the house load, I notice that sometimes some of them have zero, or very low output, rather than evenly distribute the load over all of the MPPTs. Why is this and how does the system determine which MPPT will carry the load and which will have a rest?
the units act on voltage , there is no power sharing or such, So if one MPPT is fast and brings the power to its setpoint the others will just wait until there is something to do for them. symmetrical wiring can improve , but in general there is no issue
Johannes, based on another comment you made, it seems the Autotransformers can work in either direction? Or the power source is always on one side (inputs vs outputs)? Eg. 1) taking 240 source --> 240/120 split or 2) taking 120 source --> 240/120 split or 3) taking 120 source --> 240
Thanks for answering a question for humbleroad (UA-cam) about putting inverter/chargers sideways. So it doesn't matter for the 375va upto 3000va? We didn't ask it but I said you should check with Johan 😄
We own a Multiplus II, with 150/70 MPPT, Cerbo GX and 4 x US3000C PylonTech batteries etc. Is there a way that shore power can be switched on/off, according to the percentage of battery available? For example, if batteries drop below 50%, shore power turns on. If batteries are at 100%, turn off shore power. Thanks for any help/suggestions.
Hello Victron, thanks for these videos, they are very useful. My question: how hot should a Phoenix Smart charger 12/50 become in normal operation? I have this charger connected to a Lithium (Lifepo4) battery an when the charger is in bulk mode outputting it's full rated 50 Amps, it gets very hot. IR camera readings show temps in excess of 70 degrees Celcius. I know that power electronics tend to get hot as they run, but is 70 degrees too hot?
I have a 12v multi and my son has a 24v in RV install. both are tripping shore power breakers even when setting shore power limits below shore power capacity. I’m plugged into 20 amp house current w limit set to 10amps. main breakers in RV are even turned off so there is no load. My son is at RV park. Thoughts?
Referring to the „mains detector“-feature on 1st generation MultiPlus. Will that also work with two MultiPlus units in parallel operation (Master/Slave mode) ? Thank you.
Hello, great video series and very insightful. I try to find the best option for my off grid van set up. unfortunately you dont provide VICTRON EasySolar-II GX in 12 Volt format, thats where I wonder if I use the 24 Volt model and a Orion TR Converter from 24 V to 12 Volt for my van system ? I see instead of buying a Cerbo, MPPT, Inverter and a smart charger, The Easy solar 2 GX includes them all.
I have an induction cooking island. Currently it is connected to a single phase of my house using 2x16A breaker switches, the phase is "25A" The usage of that cooking island actually never surpasses 3kW, but the island is rated for max 7.2kW if I turn everything on on full. So my question is: If I use an MP2 5000 in offgrid mode, would it suffice as long as I don't go full (my battery current drawing capacity will be around 400A to 600A when my design is finished. That's a side effect of having to store 3 days of energy for very very dark days in off grid). And more important: if my cooking habbits change, would it suffice to add an MP2 5000 in parallel? Because the parallel thing is what I can't seem to find. I assume a cerbo gx will tell N MP2 devices that the output is shared with other MP2 devices. So MP2 out- high-amp breaker-high voltage bus-low-amp breaker . The High amp breaker is to disconnect a faulty MP2, and maybe it can do the RCD too. Also: in my next house I optionally will have a 1..4kW grid if the solar fails. Would that make a difference in the configuration?
Ah, and if I did go full on that cooking island, and I somehow got 7kW for 10 minutes or longer, am I correct to assume the MP2 will give me a middle finger and shut down the output? Or will it go in another way in a failsafe mode? The issue is: I'm not sure what is going to be in my next house, so I just want to buy a stack of MP2 5000's and reconfigure them as needed, maybe even having a spare. But they will all be the same build and firmware.
We have a MP3k in our RV, feeded by a LFP Battery. Works great. MP offers a TR port to charge the starter battery too (which is AGM), although with only a few amps. Two questions: - I've heard that this port is ALWAYS active, even if MP is not attached to AC-in but supplied by the LFP battery, correct? - How to configure this port (voltages etc.)? Thank you!
Yes this is always active and will charge the AGM when the lithium voltage is high enough (charged by something) , there is no configuration possible on this
Maybe your next video could explain the basic wiring diagram for incorporating wind into an off grid system that also has solar panels. There’s very little information online about Victron and wind integration. Does the output of a bridge rectifier go into a dedicated MPPT or a DC2DC Orion product and the panels need their own MPPT?
That's because we dont have any products for wind, A solar MPPT should NOT be used with wind, it may lead to damage and certainly a non-optional efficient algorithm. A DcDc is slightly better but also not really optimal
@@johannesboonstra6917 totally agree the way the max power point tracking is working can’t load turbine correctly. pwm has bit better characteristics but not best either.
On the mastervolt which I had before, you had for the combi/multiplus 3 options. One for power, the hole inverter, one for the charger and one for the inverter. In that way you could have 230v, and in case there would be a powerout, the inverter would not kick on. This easy feature is a thing I'm missing on Victron. It has to be on the vrm and cerbo display. Could this be implemented via an software please? I would assume this could save power since the mulit don't have to be standby on the inverter and charger.
A Multi is bi-directional, so there is no "charger" or "inverter" part, its on as charger/inverter or not. it can of course ignore the AC input (stay in inverter mode) or stay of even though there is a shore connected.
@@johannesboonstra6917 thx a lot for the reply. Yeah so far have four option on, off, charger on, inverter on. But missing a fifth option. In which the charger and inverter is turned off, but 230v Is still running through, in case shore power is connected. This was a feature which the mastervolt system had, which I found quite useful. For my usage, it's when I'm off the boat, I have a dehumidifier on. Sometimes the power will go out for different reasons. It's then nice to set this setting on, and then not having to worry about draining the batteries in case of a power out. Once you get back onboard and need the backup of the inverter it would then be turned back on. This would be an easy way of changing the operation of the multi, without going though a lot of sub menu's
I have the Victron Bluesolar Charge Controller, 150|70. Which dial setting should I use for charging FLA golf cart batteries (2 six Volt batteries in series to produce 12V). The manual was confusing in that I did not recognize the different types of batteries listed for the different types of batteries. The manual did not have a setting for FLA type batteries. Thank you.
Thanks for your replies Johannes. New question: I suggest an intergration of Alfen EV chargers (company also based in Almere). These are very common, and have a Billing interface to a lot of companies for instance Eflux onboard. This feature is not present at the Victron chargers.
the main purpose of our EV charger is to use it n combination with a ESS system to charge at surplus. This is for home usage. We do not have much intrest in billing features and such I am afraid.
@@johannesboonstra6917 The billing feature of an EV charger is especially usefull for home usage! Employees will be paid automatically for their company cars electricity by their employers. Company's like Eflux offers this service by using the Alfen Pro wallboxes.
The output of generators is often not stable and/or doesn't have a nice sinewave. If I connect a generator on a Multiplus or Quattro will the output, 230 V, be "cleaner", more stable. As if the source is from a batterybank? Or is de current from the generator directly pushed through? Groet, Jur.
no, that's not the case, in fact mostly sources like a generator have issues with this as then the frequency can become unstable. at inverters the frequency is not related to the loss

Hi Victron. I saw the cerbo at Düsseldorf Boot. Running a new software (think it was 3.22). Which looks WAY better then the current version. When will it be possible to update to this software?
Hello Victron, i´m from Germany and we have very high energy price. One way to reduce costs is to use an exchange electricity tariff. When will Victron have software ready for series production? I think Google Translate isn't really that good. But you understand what I mean. Please bear with me.
Hi, please can you tell me how do you calculate the the run time of a lifepo4 48v 15kwh battery running a 1kw resistance load at 230v AC through an in inverter. Thanks. How long would it run for ?
The fast one is divide the capacity by the load , so 15/1 is 15 hours In real life the battery capacity shouldn’t be used 100% but about 80-90% And the inverter has a 10% loss So then it’s more 12kwh / 1.1 = 10,9 hours
Hi, I have (1) Ecoflow balcony hybrid solar plant. Delta pro battery - inverter is connected and charged via Ecoflow Powerstream, when it creates a peak. I have also (2) Victron 150/35 for charging my 12kWh 51,2V 230ah battery with solar panels. This battery is connected to Delta pro via XT60 solar input and charges Delta pro. One day in the morning, my battery was at empty 0% (battery charged Delta pro inverter - battery all night) and Delta pro was at 80%. When the solar panels via Victron 150/35 started charging the battery with just about 100W, Delta pro started to work at maximum with the full power of the fans, so I immediately turned Delta pro off and also the battery off. After a minute I unpluged the battery from Delta pro and turned Delta pro back on. Delta pro start to work normally. I turned the battery on after theat and it started charging from panels via Victron as usual. Is Victron pushing to much into Delta pro in this case? What fuses and where should I put, to be Delta pro and battery protected ?
Question about the Victron EV charger. Is the any difference between the 1 and 3 phase models? Or is this a configuration parameter? Does the unit support switching between 1 (2) and 3 phase charging? The Modbus list suggets a function like this. The minimum 3 phase power is 3x6x230=4KW. For most of the this is to much, and 1 phase 6 or 10A sufficient.
In a grid connected ESS system I would like to limit the power going in and out of the house. I measure this with an EM540 grid meter. I can limit power with Greed feed-in/Limit System feed-in. But that is measured at the Multiplus and not the actual Grid-in. And it does not have any effect on the system as far as I can see. Is there a possibility to maximise the real Grid feed-in/out so the the house grid circuit breakers will not be overloaded and I can charge/discharge at maximum capacity? Or is the setting in the Dynamic ESS (maximaal afname/teruglever vermogen) actually using the EM540 Grid meter? My Multiplus (3 phase) use only AC-in 1. All the loads and PV are before the Multiplus.
Hello @@JohannesBoonstra-ol2nz , thanks for your answer that makes a lot clear why I could not find this setting. Can you put this on the list of feature request. Somewhere near the top if possible :) I do not want to blow my (Liander) fuses.
Hi I have recently upgraded my old system with a multi GX. It's running in inline ESS mode. It is working perfectly as expected with interception & injection of energy. The system has 2 energy inputs on the load side 1 PV & 1 synchronous generator. However I would like to add current monitoring for reference. Can the 3 channels normally assigned for 3 phase on the Victron smart meter be assigned as individual loads, for example PV, Generator & Car chargers. There is a Generator icon on the VRM screen already. Your tech talks are very informative. Are there any plans to produce multi GX 8000 & higher as they are so much neater in installations?
I replaced a Signature Solar EG4 inverter with a Multiplus II in order to reduce idle consumption in my small solar system. The EG4 was simple to set up and combined solar, battery and grid power with selectable priority. With the Victron, you only have grid or solar/battery, so you have to constantly juggle battery charging to keep the battery below 100% SOC, and you wind up with multiple charge/discharge cycles to keep the battery in a usable range. Each charge/discharge cycle means power lost. I looked at ESS, but I don't want to run the risk of supplying power to the grid. I also don't like the idea of relying on an external processor for system control (Cerbo).
You have the same functionality of prioritizing solar over shore power with the ESS system but since the Cerbo is not contained inside the inverters you have already ruled that out. The inverter can be set up so that there is no back feeding to the grid and you can choose a low point for your battery that the inverter will maintain without charging but simply maintaining the load and keeping the battery from discharging further. The system will learn your usage and has the capability to adjust the lower limit as well. Have you seen the forecasting capability on the VRM site that is available with the Cerbo as well?
The solar priority feature doesn’t work well at moment, because it’s limited to dc loads. With optional “ignore AC” we didn’t it solve everything needed neither. Now one option is to go on an ESS, but sure not the recommended way for a houseboat with a Quattro 10k When comes an additional ESS like update for solar priority, where ac is also included?
The ESS is not suit to be used for mobile systems because of safety reason, not technical of course. The solar priority is for boats with are left for a while when still being on shore power. If you are living onboard the energy consumption is often higher then what the panels do anyway right?
Yes right, the 12kwp panelpower is not enough for Wintertime, especially with using heatpump as well. You mean Security reason like ns protection, but thats a possible Upgrade to fix that. With the newest Quattro firmware and configured ESS, it could be possible to use a Generator later, right?
We maybe Talking on different things, which limitation you mean. For me its everything good, when i upgrading the Quattro with external ns protection. Thanks for your help and advise, also for Information and storys of victron installations on on this channel.

I turned the battery on after theat and it started charging from panels via Victron as usual. Is Victron pushing to much into Delta pro in this case? What fuses and where should I put, to be Delta pro and battery protected ?

Question about the Victron EV charger. Is the any difference between the 1 and 3 phase models? Or is this a configuration parameter? Does the unit support switching between 1 (2) and 3 phase charging? The Modbus list suggets a function like this. The minimum 3 phase power is 3x6x230=4KW. For most of the this is to much, and 1 phase 6 or 10A sufficient.
In a grid connected ESS system I would like to limit the power going in and out of the house. I measure this with an EM540 grid meter. I can limit power with Greed feed-in/Limit System feed-in. But that is measured at the Multiplus and not the actual Grid-in. And it does not have any effect on the system as far as I can see.
Is there a possibility to maximise the real Grid feed-in/out so the the house grid circuit breakers will not be overloaded and I can charge/discharge at maximum capacity? Or is the setting in the Dynamic ESS (maximaal afname/teruglever vermogen) actually using the EM540 Grid meter?
My Multiplus (3 phase) use only AC-in 1. All the loads and PV are before the Multiplus.
The limitation on current, or activation on power assist is on the internal measuring only I am afraid.
Hello @@JohannesBoonstra-ol2nz , thanks for your answer that makes a lot clear why I could not find this setting. Can you put this on the list of feature request. Somewhere near the top if possible :) I do not want to blow my (Liander) fuses.
Hi
I have recently upgraded my old system with a multi GX.
It's running in inline ESS mode.
It is working perfectly as expected with interception & injection of energy.
The system has 2 energy inputs on the load side 1 PV & 1 synchronous generator.
However I would like to add current monitoring for reference.
Can the 3 channels normally assigned for 3 phase on the Victron smart meter be assigned as individual loads, for example PV, Generator & Car chargers.
There is a Generator icon on the VRM screen already.
Your tech talks are very informative.
Are there any plans to produce multi GX 8000 & higher as they are so much neater in installations?
hello, yes that would be nice but isnt an option (now and the near future) I am afraid .
@@JohannesBoonstra-ol2nz Hi
Thank you for responding.
Does that apply to both monitoring & larger GX models?

I replaced a Signature Solar EG4 inverter with a Multiplus II in order to reduce idle consumption in my small solar system. The EG4 was simple to set up and combined solar, battery and grid power with selectable priority. With the Victron, you only have grid or solar/battery, so you have to constantly juggle battery charging to keep the battery below 100% SOC, and you wind up with multiple charge/discharge cycles to keep the battery in a usable range. Each charge/discharge cycle means power lost. I looked at ESS, but I don't want to run the risk of supplying power to the grid. I also don't like the idea of relying on an external processor for system control (Cerbo).
You have the same functionality of prioritizing solar over shore power with the ESS system but since the Cerbo is not contained inside the inverters you have already ruled that out. The inverter can be set up so that there is no back feeding to the grid and you can choose a low point for your battery that the inverter will maintain without charging but simply maintaining the load and keeping the battery from discharging further. The system will learn your usage and has the capability to adjust the lower limit as well. Have you seen the forecasting capability on the VRM site that is available with the Cerbo as well?
The solar priority feature doesn’t work well at moment, because it’s limited to dc loads. With optional “ignore AC” we didn’t it solve everything needed neither. Now one option is to go on an ESS, but sure not the recommended way for a houseboat with a Quattro 10k
When comes an additional ESS like update for solar priority, where ac is also included?
The ESS is not suit to be used for mobile systems because of safety reason, not technical of course. The solar priority is for boats with are left for a while when still being on shore power. If you are living onboard the energy consumption is often higher then what the panels do anyway right?
Yes right, the 12kwp panelpower is not enough for Wintertime, especially with using heatpump as well.
You mean Security reason like ns protection, but thats a possible Upgrade to fix that.
With the newest Quattro firmware and configured ESS, it could be possible to use a Generator later, right?
that's not a matter of a Victron upgrade , every brand has the same limitation on this , so there is no upgrade possible.@@scalty2008
We maybe Talking on different things, which limitation you mean.
For me its everything good, when i upgrading the Quattro with external ns protection.
Thanks for your help and advise, also for Information and storys of victron installations on on this channel.
That's maybe correct. With an external NS protection its still NOT advised to use ESS on a mobile application. @@scalty2008
