hi, i would like to know if victron mppt charge controllers support wind turbines? if yes could i run 2 controllers in parallel, one with solar and one with a wind turbine?

Thanks

Lief.

Hi all - Having used these forums for the research/planning, I wanted to share our successful experience with adding a 400W Wind Turbine (Primus Air Silent X) to our Victron-based solar power system and enabling remote monitoring capabilities via the Cerbo GX and VRM.

We installed this on Greens Ledge Lighthouse - which is about 1 mile off the coast of Norwalk, Connecticut. We have ~3kwh of solar capacity and wanted to add wind to help provide supplemental power in the winter months, given our abundance of wind resource.

To enable remote monitoring, we used a SmartShunt configured as a DC Energy Meter. We initially set it to "Wind Turbine" but this did not show up in the VRM (only accessible via the VictronConnect app and Remote Console).

When changed to "PV Charger" it showed up in the VRM alongside the solar panels, and this has been a good setup for us. We're able to see real-time production in VRM, see historical production via a device widget in VRM, and track the cumulative output via the VictronConnect app.

Production-wise - we've been monitoring it for about 2-3 weeks and are on pace to produce about 20kwh for the month. It has a steep power curve, so the vast majority of production comes when winds are in the 20-30mph range. We produced about 3-4kwh in a 24-hour period when we had ideal conditions.

When wind speeds are below 20mph or above 30mph - the output is generally minimal. However - the unit is not optimally positioned (about 20-30% of the wind is blocked by the lighthouse), so others may have better experience in lower and/or less turbulent wind conditions.

We're happy with the production and are considering adding a second and perhaps a third unit. We'll attempt to optimize over the coming season and report back any significant findings.

We post updates about the restoration work and the off-grid systems on our Instagram and Facebook if folks would like to follow us and/or ask any questions.

How many of you have added a small home wind turbine to your solar system.

Hello. I am still new to the world of solar/renewable energy. I have become involved as my boat now has two Victron 100/30 MTTP controllers for the 2x310w solar panels. These charge my Lithium batteries -- well they will, the lithium batteries will only be installed next week (today lead acid batteries are installed). Of course, these controllers are configurable and I will swap them over to the lithium settings as we drop the new batteries in.

I am adding a Wind Turbine to help out during times of little or no sun - while the supplier tells me that its fine to connect to the batteries, I am deeply concerned due to the lack of any configurability on the (supplied in the same box) wind turbine controller.
So I was considering (without sufficient knowledge so that I why I am here) adding a

Orion-Tr Smart 12/12-30A Non-Isolated DC-DC charger between the provided controller and the battery. My goal is to regulate/clean and control the power coming from the wind turbine.
I also saw a couple of suggestions to use the Victron BMS to do the same job.

Can you please help me with a solution - not requiring too much knowledge or a major build-out -- I want to protect the lithium as much as possible.

Thanks heaps for your input.

Hi all,

Grid parallel ESS

24V system

SmartShunt 500A

2x MPPT 100/30

Multiplus ii

Cerbo Gx

4x UltraMax LiFePo4 102Ah 24 "drop in" batteries with internal BMS in parallel (408 Ah)

500W wind turbine (not yet integrated)

I have a small wind turbine which I want to safely integrate into my existing ESS setup.

This is the charge controller which was supplied with it (Amazon link) https://amzn.eu/d/d7SEs6C

1. Can I safely use this type of wind controller to integrate with my existing setup? I would intend to place another SmartShunt in-between this and the existing Shunt and configure it as a DC energy meter, so as to see the energy listed separately on thr Cerbo.

1a. If I can't use this controller, what sort of controller can I use?

2. How do I prevent overcharging of the batteries? I don't want to create an unsafe situation.

3. Anything else I should be aware of?

Many thanks as always.

Hi,

I've just fitted a Multiplus II ESS system at home with 4 off the Pylontech US5000 batteries and it's working beautifully. We have a Britwind 5kw wind turbine supplying power to the house via an SMA Windy Boy 5000 inverter. I have set this up on the critical loads AC1 out so it can supply power to the house even when we get a power cut which happens fairly often where we are in the Highlands of Scotland.

We have a power cut at the moment and I am a little concerned what will happen once the batteries have fully charged. Normally any excess electricity would just bleed back into the grid but as the grid is isolated I am unsure what will happen once the batteries get to 100%. Will the inverter cut it's output, will bad things happen?

I should add that the Windy Boy is around 10 years old and does not communicate to the Cerbo GX.

I can just isolate the Windy Boy manually from my system and then it will shut down as it used to in a power cut but obviously I may not always be on hand to do that in the future.

Can anyone let me know what happens if a 5kw inverter output has nowhere to go?

Thanks, Barry

We are a small start-up that is 3D-printing windturbines from recycled plastics. We would like to know how we can connect them to the grid with and without solar. For now we have a windturbine of 500Wp and 3000Wp that we want to test in this set-up. Our MPPT-controller also has a DC-DC converter so output voltage can be whatever it needs to be.

Connecting our windturbines to a DC-bus would be an option to consider:

However, it appears that only the Multiplus and Quattro can connect to the grid? We are in Europe (230V, 50Hz grid).

We have read https://www.victronenergy.com/live/ac_coupling:start and watched https://www.youtube.com/watch?v=tbpQzEZTElI but these questions remain open.

Just purchased a small wind generator, I want to add to my RV Victron system, I have a Multi plus II (12v), 150-100 MPPT, and 2 Battle Born Game changers, what's the best way to connect it's output to the Victron equipment? To the MPPT, or after it? It's a 12v generator has it's own controller that's needed to provide braking, can I just connect the wind generators controller output to the input of my Victron MPPT? Since it's a mobile system I want to make it as simple as possible but efficient and safe for all equipment.

Hi.

I have a cerbo gx in the cabin. There I have a shunt from before and want to add an extra shunt. The plan is for it to measure the 24v dc current coming from the wind turbine (Primus Windpower Air 40, 24V) into the battery bank. will this work?

The "4min" pictures show the effect. In this case we came from Float. The battery is full, no current is flowing. Everything is fine. Then at the load output of the MPPT a light bulb is switched on - about 2 A the bulb wants to pull at 12.75 V = 25.5 W. Makes sense. But the load from the generator starts to swing now from zero to 150 W.4min Solar (W) and Load (A) 20190730-093526.jpeg

The charge controller seemingly can't cope with controlling that, because when it tries to take the voltage back up, it brakes the water wheel, voltage drops and current goes down simultaneously.4min Solar (V) and Batt (V) 20190730-093613.jpeg 4min Solar (A) and Batt (A) 20190730-093635.jpeg

The pictures "42min" show the course over a longer period. Sometimes it goes smoothly for a few minutes, but then everything oscillates again. 42min Solar (W) and Load (A) 20190730-112209.jpeg42min Solar (V) and Batt (V) 20190730-112228.jpeg42min Solar (A) and Batt (A) 20190730-112249.jpeg

The currents jump up to 10A and down to 0A. You can also hear it in the running noise of the system, how the generator grabs and brakes and then lets go again. Definitely not good electrically for the battery and mechanically?

Is there a trick for hydropower units? From my point of view, the charge controller is too fast? If it were a PID controller, you could tune it. But I didn't find any parameters that could be tuned.

We are at a water wheel with a weight of approximately 1 ton (3.5 m diameter, 1.5 m wide); with the water flow and fall height, theoretical power 100 W, rotating at ~ 10 rpm IMG_3530.jpg-> 3 stage gear system to increase rpm IMG_20180323_181324.jpg-> 3-phase AC generator (ZXA 50500) -> bridge rectifier -> BlueSolar MPPT 75/10 -> 100 Ah 12 V battery

I have 15000/200 Quatro with 20 360w Victron solar panels and 3 banks of 48v battery's . I would like to include a wind turbine into the system to assist in battery charging. Can this be done and how ,

Hello everyone,

i would like to integrate a wind turbine from "TESUP" Link into my system. I got the following setup:

Grid connected Multiplus II with 10x PylonTech US2000C and a Fronius 8.2-1 on the AC-Out1 (which is connected to the rest of the house). Could someone tell me what the best way is to integrate the Wind Turbine into this sytem ? Should i buy another AC Inverter from Fronius? Can i connect a 2nd Inverter that TESUP offers at the AC-Out1 in Parallel to the Fronius ? Would it be better to connect their DC inverter directly to the batteries ? I have no idea what parts i should source for this project so any help is greatly appreciated. Please feel free to link/offer me alternative Turbines.

Best regards,
Oliver

• Hi.

I have a 45kva victron system with 3 x 15 kva invertors.

Have 1x 60kw blue nova battery

85x 330 solar panels.

I need to change the incoming charge of the system.

When i have no power and need to run generator to charge the battery it charges at about 12000 watts.

This is a 3 phase system.

How can I change and which setting is it so that it can charge quicker than 12000 watts?

I have a 60kw generator and it needs to run properly I currently charge system and switch on all electrical items and still not able to keep generator happy.

It can be raining and I have to switch on irrigation pumps to keep generator happy.

Surely I can change setting on victron to take more current?

Thank you.

Hi all,

Cerbo GX with ESS with DVCC

MultiPlus ii

SmartShunt

2x MPPT 100/30

24V battery bank (8x 6V FLA in series/parallel)

I have a 500W turbine which I want to integrate into the Victron system. This currently has a simple 24V controller. How should I go about safely integrating this with the existing system? Do I need to make any special considerations or can I just connect the controller output to the battery bank?

Many thanks.

Hello I have an AC generator powered by a hydro turbine. I need an interface 1140 but I can't seem to order one of the 2 remaining in the global inventory. How do I get one? Has it been replaced by another part?
