I need an Inverter in the 3000VA range. Ideally I want an easy way of driving a pump as opportunity load.

The Multiplus should have 2 AC outs as I understand it. It also has a multipurpose relay. Can the 2nd AC out programmed to come live due to whatever state I want it to programme it or is it only ever live/off due to AC in available or not?

The Phoenix unit is not much cheaper than the Multiplus but is missing quite a lot of features due to the missing charger part but the inverter specs look the same on paper. The Phoenix is however advertised as for industrial use and uses a special HF something or other. Is the Phoenix more capable in any regard or is the Multiplusses inverter side just as capable with a ridicolous good package price? I dont actually need the charger.

Does the Phoenix multipurpose relay have the same assistants available as the Multiplus? With the inverted generator start from the other day, the opportunity load could be engaged reasonably easy if available.

How does AES work in a technically specific way? Is it only in action at basically zero load and goes back to normal shape under actual load and so spares the user to wait for 2 seconds at the worst?

Are there loads that dont like AES and blow up/dont work? My neighbour is green with envy about my Victron setup and now wants one too. He has however a very troublesome electronic jigsaw that is basically the maker or breaker for this deal and is very precious about its electricity shape for its softstart/rpm and refuses to start if it doesnt like it. On a regular operation and waveform it starts fine, he also likes the low idle consumption of AES mode...

Diode D17 between the two input terminals! model 750 12V!

Does anybody know which diode is this D17, between plus and negative terminals on the phoenix 750 12v inverter? victron energy representatives replied to me that they don't have any more the technical manual of this old top secret product so nobody knows anymore or they do not wish to share this highly important information!

Hi, I get a connection refused error when trying to connect to https://docs.victronenergy.com/vrmapi/overview.html

Any reason for this? Is the page still valid?

My Phoenix 12/750 shows a red light on the status. Switching on/off, disconnecting the cables and putting back didn’t help. What ca I do? Thanks!

I have just got 3 X Victron 150A Smart Lithium batteries. I was advised to initially pre charge them with a Blue smart 12V/15A charger, set to lithium and charging at (4 amps not 2 edited) amps. Charging the first battery, went fine and ended with 13,44V and all cells at 3,36V stating "Ready for use". The next battery got to 14,06V and stated "Busy, charging disabled" and cell voltage at 3.90V 3.38V 3.37V 3.41V. After removing the charger, all cells next morning was on 3.32V and stated "Ready for use".....The last battery done just about the same as number 2............What am i doing wrong or is the 2 out of 3 batteries faulty?

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.

Hi I have bought a Victron Blue 15-60 solar charger and find it has excessive RF noise output up into the low VHF bands (50 MHz). I see others have also seen this but no answer seems to be forthcoming. I have not tried to put any filters on the solar input lines (I suspect the noise is radiated back out the cables to the solar panels). Maybe I should have checked a bit closer to see of the device really lives up to its C Tick status.

Other than me spending endless hours trying to supress the noise this device generates across HF and VHF has anyone else had any luck making these things quiet? I have many other switch mode power supplies but none as noisy as this thing..

Settings for 100/50MPPT

I have a MPPT 100/50 connected to one Renogy 200ah Deep cycle Pure Gel Battery. I need the correct settings for the rotary switch. The controller is connected to 4X100W solar cells which are connected in parallel. Would appreciate any help. Thanks in advance

Both controllers are working fine at ''Bulk' and ''absortion'' mode but one stop working at ''Float'' mode, Why?. Both controllers have version 1.39. I noticed that one controller blink every 3 second at ''bulk''mode, Why?

Hi!

I have a 48v install with s2p2 24v smart LFP battery with a Quattro connected to it. I have almost 3000 data points in VRM and see that the voltage never goes above 54.5. With other installs I see that the voltage goes to absorption where the cells are equalised by the BMS.

Also, maybe it is unrelated but I can't seem to connect to the remote console, although I am almost certain that I have enabled the feature.

Any suggestions?

Hi,

My BlueSolar MPPT 75/50 (v1.12) has been working for many years, I recently connect to my laptop and VictronConnect, it detected a new firmware v1.39 and I have to upgrade to continue using VictronConnect.

I upgraded the firmware but now charging staoped and there is a error on Victron software "#116 Lost Calibration Data" its not working anymore. Bulk and Absorption LED flashing blue simultaniously.

I down loaded v1.43, upgraded but still same issue.

Can anyone help revert back to the original firmware v1.12 please, my device is 6 years old so cant send back to dealer.

Any help will be appreciatded.

1- What is the exact charge voltage temperature correction coefficient programed into a Multiplus (as default)?

I can't seem to find this documented anywhere, apart from the graph in the appendix pages at the back of the manual. Based on this graph I have roughly calculated it but would like to confirm 100% - as the graph may only be pictorial.

2- Is there any way to update the Multiplus charge voltage temperature correction coefficient?

I have had another look in VE Configure today but couldn't find a setting to configure it.

Thanks in advance, Mark.

Hi All,

I am hoping to learn from others and also to find some peace of mind that I have correctly set up my new Victron Connect system. Any thoughts much appreciated.

This is my set up:

• 4 x 110AH AGM batteries (house bank)
• I have 2 x 110w solar panels wired in series
• 1 x 100/30 smart solar MPPT charge controller
• 1 x BMV-712 smart battery monitor

These are my current victron connect settings for my battery monitor and also for my mppt (no sun in Greece today and so I've just put my 50Amp battery charger on!)

A few of the other things I don't understand. Sorry!

• Why does the 'State' say open as opposed to Bulk/Float?
• Shouldn't it be charging at 14.4V as opposed to 14.2V?
• What should I be doing with regards to 'Synchronising SOC'....'Zero Current Calibration'...& 'Manual Equalization?'

Many thanks

Alex

I have turned on MQTT on my CCGX and I am able to subscribe and get messages. I want to be able to change the generator start/stop rules which are based on the Battery state of charge. They are current at 50% and 70% but I want to be changing them programmatically depending on forecasts. Does anyone know the topic to publish to so these values could be changed?

I have EasySolar 24/1600 and I have same problem like this EasySolar ESS randomly switches charging-discharging mode. This problem is only in ESS mode, in HUB1 mode works stable and without problems. The problem occurs, when it is broadcast remote command on the 216,7 Hz. Tone frequency 216,7Hz is superimposed to mains during broadcast remote commands. This tone frequency is used most of the region in Czech and Slovak Republic.

Is there a way to configure a high voltage cutoff the Smart MPPT 100/30 uses to prevent surges from causing charging voltages beyond specs of battery? I recently got a Gel battery and they are sensitive to high voltages. My charger gets voltage/temp from my BMV battery monitor, however sometimes it misses bluetooth voltage update packets, and on intermittent cloudy days, there can be sudden surges in output current, but if the battery is mostly full already, the voltage will jump as high as 14.85 volts before the MPPT finds out and can back the current off to maintain the 14.2v it should be. Is there some kind of protection setting that can prevent this? This was an expensive battery and I dont want to damage it,

Hello from the USA.

I see the Canvu Extender needs 8-32vDC to function so if the battery is 48vDC nominal, can I use the Orion ORI482428110 isolated DC-DC converter to whack the DC voltage in half? OR: will the Canvu think we're running a 48v Quattro from a 24v battery & throw an error?

Assuming that the input voltage does not inform any Canvu measurements but only powers up the Venus device...could I also use an AC to DC converter to get a steady 24vDC for that purpose?

Thanks in advance, community folks~

Does Multiplus AC Out 1 and AC Out 2 share the same Neutral? Are the bonded together and is it a problem if I wire the neutrals together and AC2 Out is tunned off? I don't want to make my campfire inside of RV. haha

Installing MP 3000 in a 5th wheel. Confused over gauge of wire to use on chassis ground lug to RV frame? Have read where it should be same awg of "conductor" wires? Think abyc standard specifies so.

I'm using 4/0 battery/inverter DC cables and have 400ah battery bank (lithium).

What chassis ground wire size is correct?

I am looking at implementing an 'intelligent' energy harvesting system using a recently installed system that has PV array and a Pylontech battery bank and the above plus a mppt 150/70, that is to use a certain/calculated amount of stored energy in the evenings, and then restore that with PV sourced electricity via the mppt 150/70 the next day. I have made a seperate contoller to do this, that can monitor the SOC from the Pylontech bank via CAN Bus messages, so that once the SOC quota is used it will go back to AC power. I will activate the Inverter by an external transfer switch to disable the AC in and that will get the Inverter on line.

What I don't want the Inverter / Charger to do is use the main supply to charge the batteries automatically when it comes on again, that will be done by the PV the next day, I know one can switch off "Enable Charger" in the VE Configure but I want to be able to do this via a control signal or software command to the Venus or the Quattro everyday and can't seem to find any way of doing that so far.

I would appreciate any information in this regard.

One way of doing this is to switch OFF the Inverter by the remote control which is easily done but then there would be gaps in the data on the VRM portal since the Quattro monitors the main feed in terms of power supply.

Thanks in advance.

I recently bought to my existing system a Victron SmartSolar Charge controller MPPT 100/30. The idea was to replace the old controller with this one. Well, now when I wanted to install it I noticed there's no incoming place for the cables going to the load (lights, usb and so on). In all the controllers I've had before there's been incoming connectors for the battery, the panels and the load. So sorry for not getting this, but how do I do this, what is missing?

Hi,

I have a B&G Zeus 12 from around 2012 and a new Victron Venus GX. Can I connect the Venus to my plotter to show the data, like you do in this video? https://youtu.be/RWdEQfYZKEs

Multiplus.II 3kw .. connected.. 4kwh blue Nova Battery. Inverter switches on and off.

Fault report on the Portal: Internal Error.

I have a BMV 712 that is not working. It hung up on install with the firmware upgrade. Subsequent firmware upgrades fail. Shunt seems to work, but 712 doesn't register or give an LCD messages. Just jibberish. Other Victron equipment did update successfully. My dealer (I am in the U.S.A.) has not gotten me a replacement unit as promised and after 3 weeks I'm getting frustrated with the warranty/replacement process I do not know if it's Victron or my Dealer who is at fault and don't care. Just want a replacement. How do I resolve this other than ordering a new one and putting in a credit card or paypal complaint?

What are the dips on the Solar Power Yield Graph? This is on a clear sunny day with no cloud.

My Multiplus 3000 puts out a max of 66 to 70 amps in charger mode on generator even though my batteries are down 240 amps.

My battery bank is 630 amps - 12 v

When connecting the programming I do not get the choise "d" to change voltage as described in the manual. I only get a,b,c

I need to change from 12 to 24V

What to do?
