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 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 just wanted to provide a success story, and a shoutout to Victron. Thanks for making an amazing product, which has proved invaluable in our bus conversion.

We had gone back and forth about installing propane heaters/cooktops, and even considered a diesel (webasto) cooktop. When considering an electricity-based system, we considered how to limit electrical consumption, as well as which appliances or features we could live without.

We also considered several cheap inverter products, but finally invested in a Multiplus 24/3000-70-16, with a Venus GX and a BMW702. Our battery is a 200ah Lithium pack, and this is installed in our 13 meter touring bus conversion, coupled to the bus alternator via a charging relay.

In the end, we decided to just go all in - 100% electrical - and have wired all the following on the AC1 output:

- 1Kw Split system Air Conditioner (Heat Pump/Inverter)

- Dual-zone Induction Cooktop

- Full-size Microwave/Grill/Convection Combo Oven

- Full-size Refridgerator/Freezer combo

- 7kg Washing Machine

- Outlets for all kinds of tools/accessories, such as heatguns, hairdriers, hair straighteners, vacuum cleaner, computers, etc.

- Electrical Hot Water heater (on AC2), which also can be connected to the engine coolant/webasto).

We are literally still on our maiden voyage, and have visited several campsites across Europe. The ability to use PowerAssist is especially amazing, since several campsites only provided 10amps or even 6 amps of 220V service. So even with only 6Amps available shore power, we had full AC running, while cooking pizzas in the convection oven, charging our DC system (lights, kitchen fans, water pressure pump, etc.), running the fridge/freezer, and vacuum cleaning, all at the same time.

The greatest part was how we completely "forgot" about being on the road - the Victron setup gave us the freedom to cook, work, clean, and basically operate like home, without ever having to worry or consider any electricity limitations.

So thanks again for a fantastic product (and community) - the Multiplus has taken what we anticipated to be stressful and a big headache, and turned it into a completely worryfree experience.

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...

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?

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.

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

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.

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?

The VE BUS is giving a low battery alarm while the battery voltage is normal in the BMS. See picture below. There was a high current draw event and after the VE BUS voltage started swinging low when the inverter mode kicks in. Any ideas how to resolve this? The system is a split phase with 2 Quattro's and BYD battery bank of 7.5 kWh.

The diagram for the Cyrix-Li-Load shows an emergency override switch. Is there a way to do the same on a Smart BP-100?

In installations where there is no BMV, with CC GX installed, you only see the value of the SOC in the Color Control that rescues this value from the inverter. We know that the inverter is far less accurate than the BMV. In the inverter we configure the battery monitor section to show the correct value. We also find it odd that when this value is set, the screen shows 100% battery, knowing that the batteríes are not 100%.

We would like to know for this kind of cases that we can do so that the client has a reliable % SOC measurement. Especially when there is no BMV installed.

I'm designing an off grid system and I'd potentially like to use a Phoenix Inverter Smart with a Victron Autotransformer. The photo below is what I want to do:

[image]

My question is where should I attach the ground relay control (shown above) and is this setup compatible with the Phoenix Inverter smart?

From the Victron Autotransformer manual (page 3), I see that,

[image]

From the Phoenix Inverter Smart manual (page 9), I see that,

Since the system is in a vehicle does that mean I simply need to connect the ground relay control wire to the same ground as the inverter?

Thanks for your help and let me know if you need any more details!

I am running a 24v DC system with a 240 - 24v power supply and wish to add a Bluesmart to maintain the battery bank properly and give the system black start capability, a couple of questions: can the bluesmart operate as a power supply if the battery bank is switched off without interruption or does it drop supply then re power the loads. are there any concerns with the parallel sources, I am totally comfortable with the two supplies in parallel but the customer wants to hear it from the manufacturer
