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).
Q1: If I have a load output on my MPPT charger, will that be active all night?
Q2: Which cable do you recommend for wiring between the battery and the MultiPlus in a campervan?
Q3: Why doesn’t Victron make a MultiPlus range the 500VA to 1600VA in 120V for the US market?
Q4: How long does it take for the EasySolar to switch from battery in case of an electric network failure?
Q5: The older Blue Power Charge Controllers, the 150/85, can you also plug in a VE.Bus Dongle in it to monitor via Bluetooth?
Q6: How many Smart Lithium batteries can you connect in series or parallel?

Love these videos and am excited about installing some new Victron components I’ve ordered. Working on system connections, settings, and commissioning steps while I wait for them to arrive. Information is scattered but it’s starting to come together. It would be impossible to provide details for all scenarios but the manuals have the information needed to get it done. I’m expecting a mostly trouble free start up and know it will meet all my needs in this application for a long time to come.
Due to limited space I would like to know if it is okay to mount the Victron Inverter Charger 48V 3k 30-50 on a wall in a side ways orientation as space does not allow for a traditional up/down mounting.
Thank you for a very educational video. I have Victron Cerbo GX and MultiPlus 12/3000/120V-50 and Victron Smart 500 amp Shunt. Part of the circuit draws from 12dc after the shunt but the Cerbo GX Touch 50 doesn't show how much 12V DC power is being drawn. 2nd Question: which RJ45 input to the Cerbo GX do I use to connect to Raymarine MFD. Thanks so much!
For MFD the LAN connection is used, so when combined or on the same router this should work. The Smart shunt shown power in/out the battery. If you want to see beside this a current to a certain DC distribution you can add a secondary Smart shunt and have that set ups as energy meter
I have a older Multiplus 24/1600 Compact installed as UPS for data and pellets burner to work with grid failure. I want to add a smaller solar and MPPT, is there a way to consume all solarpower and not use as much from grid simultaneously? I have disabled UPS mode because my generator are noisy
Hi Johannes,
Another question regarding my EasySolar-II-GX-24/3000/70 (with a LiFePO4 Smart 25,6V 200Ah and a VE.Bus BMS V2)
Some time ago the EasySolar lost its internet connection. Therefore I also couldn't try to verify the network settings from VRM->Remote Console.
And in VEConfigure I couldn't see that information either, so I had to power-cycle the EasySolar to make it work again.
Because of this I have been looking at the various Victron control panels that exist.
The "color control" seems to be a possibility, but my dealer says the EasySolar is not compatible with that (although I doubt that).
On the Victron site I see the "color control" will be replaced by the "Ekrano GX", but that is a too extensive (and too expensive) solution for me.
What about the cheaper "GX Touch 50" or "CANvu GX"?
In the end I just would like to have a "backup" control option, that connects directly to the EasySolar (when no internet available) and has access to all essential configurations.
What do you suggest? Thanks in advance.
Don't know if u can help me. I am try to flash my victron quattro 48/5000 inverter, but I have to use veflash because it is a 100 series bios, The flash utility keeps telling me error connecting when trying to flash. Do I need to disconnect both ac and dc for the procedure to work or what am I doing wrong? Thanks
Would you consider developping a SmartSolar MPPT RS which can connect directly to Solaredge optimizers? (so we can remove the Solaredge inverter and still use the optimizers for shadow based locations)
Well the modern panels have nowadays all bypass diodes to eliminate the shading effect so the is no real need for the optimizers. So having the panel directly ion the MPPT would be technically the best as then losses are minimal. In short, no there will be no special version which can handle optimizers as that would make them less efficient.
Hi! I so appreciated your explanation in Eposide 6 of how the Victron inverters can sync with the line voltage for simultaneous charger and inverter operation. My question: I'm operating two Multiplus 3K inverters in 230 V split phase. I can't find instructions for connecting a 230V split phase generator or grid to this inverter configuration for battery charging and inverter operation. Am I safe to connect the 230V split phase input in the same fashion as I connect the split phase output, namely H1 to one Multiplus, H2 to the other Multiplus and Common joined between the two? If I do this, will I need to make some setting changes in the Multiplus configuration?
when having two units in split phase the INPUT has a N is common and the one is L1 and the other therefore L2 , and the OUTPUT has the same . So on the INPU is where the genset needs to be connected
A question.
There is an article "Parallel, split- and three phase VE.Bus systems" which states that using 15kVA Quattros, the maximum system size is a 180kVA three-phase system. Which then consists of 4 units in each of the three phases: 12 units in total. Is there any possibility to make a bigger system? What happens when you connect 6 Quattros on phase: 18 unit total? If this is impossible, does Victron plan to provide the ability to build larger systems in the future for C&I market?
when its getting bigger you will face more issue getting it symmetrical and find switches and fuses for several thousands amps. then splitting a AC distribution up in various separate systems
I have bluesmart chargers and can monitor them when on the boat via Bluetooth and the connect app on my phone but i also have a Cerbo is there anyway I can get the details into VRM through the Cerbo on bluetooth so i can monitor them when away form the boat?
No communication with the gx device is only done by a cable
Hello, i have a question about a Lynx distributor and big cables.
I need to connect a phoenix 24/5000 inverter.
Between Inverter and Distributer is 1,2m
The manual said the recommended cable is 2x 95mm² with an 400A Fuse.
If it´s possible to connect two cables an one of the four terminal with a 400A fuse or i have to split it to two terminals with two 200A fuses?
Another option is to connect a Fuse holder at the end of the distributor busbar and connected seperately.
Best regards Robert
When paralleling the cables the partalleled fuse becomes half size , so 200A indeed.
I’m looking for information on how to program a 100 amp Victron buck boost.
I am running it on 24 V.
Is there a video on setting up TS Config for amateurs?
Thanks
No not yet, I am sure your dealer is able to help (if the manual isn't clear enough on this)
Haha, that's the dutch english. But Victron is the number one and i work with the hardware for years on Yachts en Homes.

Hello Johannes,
I have setup a EasySolar-II-GX-24/3000/70 with a LiFePO4 Smart 25,6V 200Ah and a VE.Bus BMS V2
As I needed some 24V energy I connected that directly to the battery and not on the 230V output of the EasySolar to avoid the need of an extra 230V/24V power supply.
Will the EasySolar still be capable of managing the Battery correctly (as it has a VE-Bus to communicate with the battery) or will it get confused that some power is used from the battery that doesn't flow through the EasySolar?
The BMS will signal the Easyplus what to do, when the BMS signal is lost for whatever reason the Easyplus will stop working
I have a quick question. Would it be possible to improve the EasyPlus Inverter/charger unit so it has a larger invertor (3000va) and have a second/third battery charger output and modernise it with bluetooth connectivity with everything and you'd have a killer unit for use on narrowboats in the UK - a certain market!!
Everything is possible :-) , but at the moment this isn’t a priority to be developed
Perhaps later next year
Hi Johannes, I have a system consisting of a Multiplus 5000, a smart shunt, a CCGX, 3 smart MPPTs with their nominal panel arrays totalling approx 3kW nominal charging a 24V /1000Ah lead acid battery . My battery reaches absorption usually by mid morning and at that point I want to connect my electric car charge circuit to harvest the max from my panels.
My question, what is the best way to get the absorption signal from this system? Clearly I can use a standalone voltage sense circuit but i would far rather use an output from the system.
if you want to charge when the battery is "full", I would recommend that the doc of the battery is used to trigger a relay for the charger. lets say start at 9998% and stop at 85% , that way you are almost certain the majority of power comes from PV
I have a question about the Victron Autotransformer. Can that product be used with other manufacturer's 240V, single phase inverters to provide phase load balance?
yes, but when you need to control the ground relay you need to be careful as not all brands have a contractor for this
Question About the Multiplus/Phoenix: We all like a good cup of coffee in our RV/Boat, but most coffee machine draw a lot of current. For same units a modification is possible by using a diode for the boiler/heating element. For instance my Nesspresso in 1350 watt, but with the diode only 700 watt. Can I use this with a 800VA unit? Of course the AC current is still a around 6A in one direction for a short period of time while heating up.
Well you could to a certain extend but need a larger inverter then nominal to take care of the imbalance, so inshore, there is no point doing this. Just take a unit able to supply the load
@@johannesboonstra6917 Thanks Johannes for the quick reply! It was to be expected. I consider an additional Phoenix as an additional power source to the existing multiplus only for the time the coffee machine is running without shore power. Both will operatate together. As far as I now this is possible. Off course by using a transfer switch to delay the switchover from/to shore power.
I would like to know if I can use a SmartSolar MPPT CC to charge a 24v battery from a 48v battery?
hello, that's not advised there is a panel short circuit features which will get damaged when batteries are used as input
What would happen if the total load output exceeds the max. values of (eg. 15A on an MPPT 75/15). Is it just restricted and simply won't exceed, or will it blow a fuse? Background: I'm currently setting up my system in a camper van and calculating for scenario that all electrical loads are used in parallel. Thanks alot!
Then there is a change of damage, so the output needs to be fused lower then max to be safe
Hi Johannes, would you please help me to find the best setup for my system? I do have 550W, 52V panels. My roof is a little complicated. I can put two panels facing east with 30dg slope, two facing west with the same slope. Five facing south 30dg and 4 facing south with 45dg. Can I use MPPT 100/35 for East/West panels and MPPT 250/70 for south panels? Is it possible to combine MPPT 250 and MPPT 100 into one string? Is the slightly higher voltage of the panels (260 and 104V) a problem??? I consider Multiplus II 48/5000/70 Inverter and 48V battery. Would you set up the system differently? Thank you very much, Juraj
having a single MPPT per slop would be most optimal. higher voltage then the specs allow is a huge problem as that will damage the MPPT permanent. Always stay about 10% below the max I would recommend
Quattro or Multiplus charge to max 80%:
How is possible to set the charge Limit to max. 50-80% for Litium Batteries?
On lithium the absorption voltage is the voltage the batterie is 100% (full) , the absorption phase is to allow the balancing take place. If you set the absorption down also the SOC will be less. If you want to stop the charge at a certain value you could have a BMV have its relay connected on the input of the Multi. then with an assistant you can stop charge at the values you activate the relay in the BMV
Hello Johannes,
I have an EasySolar-II-GX-24/3000/70 with a LiFePO4 Smart 25,6V 200Ah and a VE.Bus BMS V2
I have some questions regarding connecting, as the manuals refer to EasyPlus equipment or just GX equipment, but not specifically to the EasySolar where everything is combined.
1) As the EasySolor-II-GX is already a GX equipment, I assume I don't need to use the "VE Bus Mains detector", correct?
2) So, then I can connect the "MultiPlus/Quattro" RJ45 on the VE.Bus BMS V2 directly to the EasySolar? If so, I connect it to VE-Bus connector inside the EasySolar, correct? And do I have to use one of the terminator plugs on the other VE-Bus connector inside the EasySolar?
Q1 the mains detector is not needed when having a Multiplus II model (such as the easy solar), the GX part is not the criteria for this. Q2 Ve bus NEVER needs a terminator , and the BMS can be connected inside the easy plus
I have your mppt 150/70 solar charger with its own solar array. I also have a pwn solar charger with its own array. I would like to charge the same battery bank with both systems through the lynx distributor. Is that possible?
yes sure, specially when they are set at the same charge voltage the charging will be done by both
what is the difference between a mutiplus and a mutiplus 2? And could you have both in the same system?
The m2 is the latest design and has a design focus more towards ESS systems. So certified double input relays are standard. Also idle power is less.
Hi. What is happening with UK EAN listing? Any plans to re-new them?
Already done all whats needed. should be on the list again shortly.
Hello again Johannes, I have the MPPT 250 100 it’s normally that it’s should draw five AMPS when it doesn’t do anything as in a idle consumption 😮
No, that not whats supposed to happen, sure it flows into the mppt/panel?
I have a Fronius gen24 on ac in. Can I use the Fronius pv point as ac in when grid goes out for multiplus 2? Thank you!
The fronius needs an ac source to be used. So therefore in off grid situations the Ac out needs to be used to connect the fronius to. Beware the max power to be connected on ac out is equal to the inverter itself
@@victrontech fronius gen 24 has a pv point backup that gives up to 3kw if there is sun. It is supposed to be used for a socket. I believe that it could be used as ac in for multiplus without issues. I should probably ask fronius.
@@RobertBoerescu why would you buy a battery based fronds to supply another battery based Victron system/. , would in my opinion best if you have one large battery bank.
@@victrontech Fronius does not have ups type functionality. There is a 90 sec blackout. I cannot accept this for critical load. This is why I have an easy solar 2. Critical load are connected to ac out 1. Fronius does not have a battery. Byd is supported and it is very expensive. I use a generic lifepo4 with easy solar. I have four 455w panels connected to easy solar. More than enough in summer. I have however 14 455 connected to Fronius. If grid goes out it stops giving power to the home but pvpoint comes up in 90 sec single phase up to 3 kw if there is sun. I was wondering if it would be feasible to use it as ac in to my victron if I need more power than I can get from easysolar battery and panels
@@RobertBoerescu then have the unit on ac out , that works best with grid connected units
It then will always work as long as the inverter is active
I have a 48 volt 270 AH lithium bank for electric motor sail propulsion with a Victron dc 48 to 12 volt 20 amp converter for trickle charging a 12 volt AGM 200 AH house battery. Thinking about adding a victron 12 dc to 12 dc 30 amp charger inline between the converter and the house battery as victron does not have a 48 dc to 12 dc charger. Is the addition of the 12 to 12 dc charger a viable and effective way to keep the house charged? Are there other recommendations?
you have a 48/12 converter to charge a 12V battery, and need a 12/12 converter for charging the same battery? from where?
@@johannesboonstra6917 My understanding is that a converter outputs a steady current and does not do the 3 stage charging that a charger will do. Not sure if the converter will properly charge the 12 volt house battery which is why I was asking whether an 12/12 charger would be recommended to be installed after the converter to additionally charge the same 12 volt house battery.
@@johnrabbetts1429 that seems to be pretty inefficient. ps with a fixed charge voltage yo can also charge the battery very well, only no as fast perhaps.
If you have 20 of the Victron Lifepo4 25.6V 200Ah Smart-A in Series Parallel for a 48V battery bank what BMS would you use?
A lynx smart BMS would be nice , but also a Ve bus v2 is a good option
@@victrontech lynx bms is only good for 500 Amps
@@brianbourke8859 Capacity of the battery bank in Ah is something else than the maximal charge/discharge current. The 102kWh (max size) bank can be charged with 500A (25kw) or discharged. Large BMS modules will become available later next year.
Will they launch inverters for high voltage batteries?
I am afraid not. Perhaps a 48Vdc model but not higher.
Can I connect a Quattro 10,000 W with Multi 5000 W in parallel? a quattro has lead acid batteries and the Multi has lithium batteries.
Only 100% equal products can be paralleled I am afraid , so a 10K and a 5K can not
probably already answered, If i have 1000x solar panels in parallel and don't exeed the open circuit voltage of a Victron Mppt will it work or go up in smoke?
It will not go up in smoke but it needs to switch the pv power if something goes wrong and as the short circuit power is most likely to high , it’s not able to do so
So … stay below the maximal short circuit spec and VOC
@@victrontech ok thanks for clearing that up.
Hi Johannes,
Almost ready for first powering up my system with an EasySolar-II-GX-24/3000/70 with a LiFePO4 Smart 25,6V 200Ah and a VE.Bus BMS V2.
Q1: In the manuals / tutorials I see the default setting is for LedAcid batteries. The Lithium battery is already connected. So on power-up the setting is not correct yet. I assume that is not a problem?
Q2: I have seen a lot of manuals and videos, but still I have 2 questions. The battery I already have connected to the Victron app via Bluetooth.
Q2a: Does the first configuration goes similar with the Easysolar, so searching it in the app over bluetooth? Because I need to setup the wifi of course.
Q2b: The VE.Bus BMS V2 doesn't have bluetooth (or has it?). So is it to be configured / updated via the EasySolar?
Q1 the settings for lithium and Lead are not that far apart in level so that's fine as start up phase. Q2 ? whats the question? Q2a the Easy solar is better set up using a laptop/cable , then you have the most options. the BMS does not need to be setup
@@johannesboonstra6917 I have switched on the system; did firmwares upgrade of MPPT and added the EasySolar in my Portal.
But now I get error: "VE.Bus System [275] - VE.Bus Error: VE.Bus Error 7: BMS connected, which requires an Assistant, but no assistant found"
The manual says about this: "configure the Multi/Quattro with a suitable Assistant. "
But it is not clear how / where to get that assistant.
@@mahyulan When lithium is selected the unit is looking for the BMS , so make sure that's connected (and powered)
@@johannesboonstra6917
Q1 Can I only select Lithium with the Windows VEConfigure software or is there an alternative?
Q2 Do I need the MK3-USB interface to connect to VE or can I also use the USB port of the EasySolar directly?
Q: Why does switch of, the SmartSolar 100/20 Load output if I connect an Orion 12-24 10 ?
There is no load on the Orion 24V side!
(I wont to increase the Power, to charge an Powerstation with up to 240W)
because the load output is for loads without startup current , the Orion will cause an overload /short circuit
I have my power station connected through the load output on my 75/15 Victron mppt. When the (lead acid) battery voltage drops under a certain point, can I set the mppt to stop the load output current? Thank you so much
How are you Johannes I have a question about the link BMS. I’ve bought the link BMS, but I decided to make my own batteries. Am I not able to use the BMS in this kind of system? I know you don’t recommend this schematic. But it is possible for me to use some of the features in the link BMS with my own batteries. The batteries built-in BMS has Canbus is that in anyway helpful.
I am fine! thanks! Our BMS systems can only be connected to our smart batteries I am afraid. This is because the combination of BMS and battery is critical for safety and lifespan. The Smart battery has its own pcb which is able to communicate , we do not supply details on this communication I am afraid.
@@victrontech hi Johannes what you are saying is basically I’m better off with the linx shut instead of the linx BMS.
@@gyngecykel you would be better off with the Smart batteries ;-) , but if you choose to built your own, yes then the Lynx Shunt is the better option.
is that 20 for each inverter or 20 if you have more than one inverter ?
20 batteries is the maximal amount of batteries , on a single BMS
@@victrontech thank you for the quick response. I thought each battery had its own bms built in, so are you saying there is a bms in the inverter/charger that is in overall control?
I haven't had any luck in the Victron community forum or the Facebook groups so I'd appreciate if you could address either or both of the following questions about the Skylla-TG charger 24 V universal input:
- The Skylla-TG charger 24v universal input unit has a starter battery charging feature, does it use power from the DC side or do I have to be plugged in to AC shore power?
- I've seen people recommend using an EMS to protect a Multiplus/Quattro from bad shore power, since universal input EMS don't seem to exist, how would you protect the Skylla-TG charger 24v universal input?
Q1 this extra power for the starter output is redirected from the main battery, So when there is enough (voltage) to also feed the starter output it will do so.
Q2 There is no EMS needed as the unit will switch itself off at low AC voltage. for (extreme) high voltage you could add an EMS but that's typically not done as far as I know.
@@victrontech Thank you so much for answering both questions, that helps a lot!! You’re a legend. :)
@@victrontech If you don't mind one last question, the manual doesn't mention it so I assume the starter battery output won't have stage charging right?
@@palebluewanders3135 the starter output follows the main voltage minus a few ten-s
It would be good idea to have a sunlight sensor system, to mean that during night time. The mppt would turn off or go into low power mode. The community forums should have dedicated sections for their one suppliers such as pylontech batteries!
That’s what’s already happening , based on the pv voltage which is in fact a big sunlight sensor. But when having load output the unit needs to remain active
That’s the reason only the smaller units have a load output as well

Hello
In my photovoltaic system, I would like to feed from the batteries into the 220V house network, e.g. via an inverter. (night feed/ permanent feed)
Does Victron offer a way to do this? The VE Smart Battery Protect would be ideal for switching the inverter, but according to the manual it cannot be connected to inverters.
Do you perhaps have another technical solution?
Thanks and Regards
JF
Please have a look at the Victron ESS manual online, there al options are listed
The Battery Protect is not ideal for inverters I am afraid, its for small DC loads. If needed you can control the inverter by using a Battery Protect by its remote port. But most inverters do have their own low voltage cut off already
because Victron inverters have the power in VA and not in watts?, example 3000va
Yes, the rating of power is in VA , as unfortunate that's the common practice with manufacturers.
It's the correct way . Unfortunate other companies don't follow . It's the most honest .
Will Victron make a competitor product to the ctek d250s? (Alternator charging aswell as solar mppt charging) for the caravan/camping 4x4 market.
Not on short term , we have these units as stand alone to give optimal freedom to adapt to the power you need

Dear Johannes, although I am also Dutch, I ask my question in English. Can I operate an RS MPPT 450/100 and Multiplus II 48-3000 without a battery? I will be added later on. Keep on the nice usefull video's!
Hi no that’s not possible , firstly because the voltage regulation of the MPPT , and also because the inverter demands faster power then the MPPT can provide is
So without battery this should not be used

Hi Johannes! I'm part of a community that is moving toward energy independence. We recently were made aware of health concerns of "dirty electricity". I purchased a Greenwave microsurge meter that tests dirty electricity noise on the 110 VAC line. I've noticed the dirty electricity is quite high coming out of my 2 Multiplus inverters that run through the Autotransformer to produce the split phase 220 VAC. Do you have any thoughts or user data about mitigating the high microsurge "dirty electricity" from these inverters?
dirty power? the Multi and other inverter we produce are full sine wave and have a limited distortion, often better the the national grid.
I can't believe the victron mppt's don't have a preset for lead acid! I expected a lot more from victron regarding this! Surely you can add a basic charge profile in an update?
Hello, I am a little surprised by this remark. Beside the one preset setting for lithium, every of the remaining 7 are all lead acid?!. As you know the AGM/GEL and OPs are lead acid batteries with all specific absorption voltage/durations.
@Johannes Boonstra yes, but the charging profile for a basic lead acid and say agm are different, and all those settings are slightly different, so which to use? I just think if there was more clarity in the options this would help a lot?
