Hydro and Wind Power

Can Phoenix VE.Direct work without batteries ?

I have a micro hydroturbine which gives a variable cc voltage between 40 and 70v and up to 1kw of power. I wonder if I can connect the Phonenix Inverter VE.Direct 48v 1200VA directly to the hydro turbine for producing 230v AC to act as an electrical generator for my off-grid solar inverter which is connected to my batteries and the house.

During the winter, there are days where the solar panels don't produce enough energy and a I have plenty of water running through the creek.

In short my question would be: could the hydro turbine be a battery in disguise for the Victron inverter and produce AC as an electrical generator would do?

Thanks in advance.

Victron Multiplus II, 2 x MPPT charge controllers, FreedomWon LiFePO and 48V DC Wind Turbine

Hi there,

I have the following setup:

- Multiplus II 48/5000

- 2 x SmartSolar MPPT 250/60

- FreedomWon 10kWh with BMS (Absorption and Float = 55.8V)

- 1500W Wind Turbine with its own controller 48V

When the sun goes down and the system is using battery power, I want the Turbine to supply power to the system (obviously when there is wind). I am not sure that this is actually happening. So my first question, can I use a SmartShunt to monitor the DC current coming from the Wind Turbine and then also display those values on the CCGX? And my second question, what would be the best settings for the wind turbine controller, as the controller cant communicate with the battery BMS?

I would appreciate your assistance.

Thank you

How to connect a windturbine (primus air 40) to monitor through venus OS. Bmv-712

I am confused please assist.

I have a BMV-712 with its shunt.

I have installed a Primus Air40. 24v windturbine and there wind generator control.

This gives me voltage, current and combined power accumulation. It also has a MCB and a brake.

I have had alot of back and forth with Primus as they insist that I need to wire the the positive and negative directly to my batteries positive and negative on the bank.

From Victrons side, I understand that all of the loads negatives should be connected to the shunt. This is to get reading.

Yesturday i got my PI with touchscreen running Venus. I am not sure if I can see anything from the turbine.

Currently the turbine is wired as Primus insisted I have it. Directly to the battery bank.

what is correct?

To the shunt or direct?

Hope someone knowledgeable can advise

Wind Turbine integration to 12v victron set up

Hi All

We currently have a 12v off grid solar setup with two 100/50 mppts that just doesn't keep up over the winter. This system is controlled and monitored with a Cerbo GX. Weve decided to add a Rutland 914i turbine with a hrdi controller as it appears suited to the weather conditions, high winds due to living on an open moorland.

If the hrdi controller is connected directly to the system would this interfere with the solar charge? Or would it be beneficial/work to have the hrdi battery output connected to 12/12-30 or 24/12-30 dc to dc charger either with or without an additional battery between the hrdi controller and the 12v system were looking to charge?

Help! I need somebody to help me with a hydro feed into an existing storage setup.

Hi all,

Are you all well? Hope so.

I am posting my questions and queries here as I am hoping to find fellow renewable energy enthusiast who will be able to help or at least point me in the right direction.

I'll cut to the chase but if anyone wants to read the rest and help I would be exceptionally grateful.

I am looking for someone in the UK (or elsewhere I guess) who has had experience in installing a pico-hydro set up. I need help on choosing the right type of turbine and how to wire it into my existing battery-storage system without frying it or anyone who happened to be standing nearby!

Here is some more detail.......

I have an existing off-grid solar system, with battery storage and capacity of about 11.98 amp hours @48v. It serves me really well as I don't use very much on a daily basis, but there is a generator as backup when the sun doesn't shine. I am completely stand alone and there is no scope for feeding any energy back to the grid as I am very remote (and nor would I consider it).

All is well here then...

However, I am fortunate enough to have access to a large head of water, a suitable drop of about (as it stands) 25m and a flow rate (when it isn't raining) of about 20l/ps, I have had a couple of engineers from a commercial-scale, local project tell me there is a lot of merit of installing a turbine as, if done properly, I would get anywhere from 500w to 2.5Kw from the flow.
(A point to note is that all of the above is on my land and my installation wouldn't have any impact on any other local water ways, so I don't want to get hung up on any legalities or permission things).

I am desperate to find someone who can help me on this. I am no electrical engineer but from my own knowledge, research, input from others I am certain there is merit in doing this - I think it would be a travesty not to try and exploit it as much as I can. I may only use around 700l of diesel a year for the generator, but if I can halve that then from an environment POV, I personally think it is worth it.

Finally, I am not looking to do this on a shoestring budget. Before I bought this place last year I factored in spending some money on the hydro. Therefore for the right help I am willing to recompense someone appropriately.

I am optimistic that one of the other 7.4bn of us on this planet someone can help me see this through. If anyone wants more info on the existing Victron stuff that is already in please I can let you know.

Thank you. Paul

Home hydroelectric videos


I have a pond (approximately 17 feet deep, 250feet x 100feet…measured many years ago, water rights information shows 5 acre feet). It has a 6 perhaps 8 inch drain that goes through a dam. The drain is reduced to 4 perhaps 2 inches (haven’t been down there in years) with a large shutoff valve. The valve when open creates a lot of pressure (PSI???…much greater than average home pressure…I’m thinkIng close to fire hose pressure). From what I’ve seen on line, this setup (after generator installed, etc.) could possibly be enough pressure to generate enough power to run my house (average). I’m not looking to generate more than a few hundred watts right now (money, time, complexity), but just wondering what steps to take to get this started. I haven’t come across any videos with step by step instructions (clear, concise) regarding install, products, etc. Looking for both DYI and commercial options.

I’m posting a short (vague) question to get things started. Happy to add more details if necessary.

Charging Lithium Batteries with Wind Turbine (In addition to my PV + Victron controller)

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.

Off Grid with Stand By generator

I have some simple questions that I have not been fully able to flush out in all my research and am hoping that someone will be able to give definitive, simple straightforward answers so I don’t make a costly mistake. (1) Of all the inverters what will be the best option for an off Grid Setup with a back up generator. I can see several options but I am not sure if I should be using a Quattro or and MultiPlus II. I want the generator to back stop the system in case the renewables are not enough to run the system and the batteries are getting low. I will be using a combination of Hydro, Wind and Solar.


  1. Max current out put 300A (200 A house panel and 100 A Shed Panel)
  2. Output Voltage 240V to 120V
  3. Generator activation when batteries hit predetermined low level
  4. Battery Charging from Generator
  5. Battery Bank 48VDC

I have attached my rough design on what I plan to do. The battery bank will be built out of LifePo4 batteries creating a 48VDC system and storing around 9600 ah. The batteries will have an average normal discharge rate 320 A per hour with a peak over 1000a but will need to be under 10 mins.

  1. If the batteries are full and wind/hydro/solar are still producing power
    1. Does the MPPT prevent the extra power from over charging the batteries?
    2. If so what doe the MPPT do with the extra power? I known in some hydro system they have a burn off resister.
  2. Can multiple Autotransformers be placed in parallel? I have seen several references in post about needing multiples, but no one has explicitly said they can be used in parallel. I need to have a 200A circuit of 120V L1, L2 for the house.
  3. Is there any reasons why a Solar Charge Controller could not be used with a wind turbine if properly sized? They hydro turbine I plan to buy have been tested with the Victron MPPT(s) and they even recommend a model to be purchased based on what I buy from them. The wind turn bine has no suggestions from the manufacture.

Victron 100/20 SmartSolar as hydro charge controller

I have a small hydro setup that I'm trying to get up and running. I've purchases a victron 100/20, awaiting for it to arrive.

My generator currently produces 62v DC after being rectified from 3 phase AC when running with no load. The generator is a motor off a segway es2 scooter - rated as a motor for 300 watts constant/700 watts peak @ 36v input.

My water source is very steady, there are no seasonal variations as I'm taking only a very small fraction of the total water source.

So, my thinking was that I had no need for an MPPT controller, and a cheap PWM controller would do nicely.

However, I'm running a 24v battery bank, so a PWM controller limits the motor RPM so it generates ~28v. This seems suboptimal.

Using an MPPT controller, it should spin at the top of the power producing curve, somewhere between 28v and 62v, and then convert the excess voltage to current, which is its primary appeal for me.

My questions are:

1. Are my assumptions correct?

2. Given my free-spinning, no-load output is 62v dc, and the victron 100/20 controller is rated to 100v input, I should have no need for a diversion/dump load, is that also correct?

3. Can I assume that the most power I should get from this motor is about 300 watts, as that's it rating when used as a motor? Or can it produce more as it certainly can produce more volts than its rated 36v.

4. Using a PWM controller, to optimise I would want to find a runner (propeller/impeller inline in tube, I'm not using turgo/pelton) that provided maximum torque at the RPMs it runs at 28v, while making sure it never drops below 28v (I can print new runner designs, so this was my planned optimisation route). Using MPPT, I have more flexibility as long as RPMs remain in a range to produce over 28v on full load, and remain under 100v with no load. Is that correct?

Apologies if the questions are basic, this is my first hydro build, it's been fun so far, but I have much to learn.

I understand the victron controllers are designed for solar, and hydro isn't supported, but I see a number of people on here who are using them as hydro controllers, so thought I might get some useful information here. Many thanks!

Phoenix inverters with wind turbines: remove battery low power switch off setting

I have 4 different wind turbines (Tesup) with 4 charge controllers (1 x 12Vdc, 3 x 48Vdc).

These 4 charge controllers are connected with 4 Victron Phoenix inverters, to produce 230Vac:

a Phoenix 12V/250W inverter for the smalles wind turbine, a Phoenix 48V/800W, a Phoenix Smart 48V/2000W and a Phoenix Smart 48V/3000W.

Problem is that of course the wind is not always blowing, so the input from the charge controllers is often very low power, or times even 0 power. And these Victron inverters are so smart they see this as an empty battery.... So they give a few times a 'low battery' alarm, and then shut off completely. How can I change this setting to 'Simply keep producing 230 Vac with any power you are fed' ? A MK3-USB cable is on it's way ;)

MPPT Charging for Hydro. Victron 150v Blue solar not finding correct Maximum power point

Hi all. i have been running my off grid cabin on hydro for over a year now. i have been useing a tristar mppt controller and fixing the correct voltage in order to load the turbine correctly. this voltage is around 50v under load. That is the ideal speed to load the turbine to in order to catch the most energy from the water. that 50v equates to the turbine moving at half the speed of the water leaving the nozzle, this is the optimum relationship between nozzle volicity and rpm.

Now i have had lots of problems with morningstar and decided to try a victron blue solar controler. I planned on useing the mppt controler to find the best voltage instead of me needing to fix the voltage to 50v. I have plugged it in and at first i found that is would be all over the place and not find a voltage and stick to it. It would sometimes get close to the right voltage but then do another sweep and loose it again. I put this down to the fact that it is acting differently from solar and could do with some large capacitors to smooth it out. I have done this now and tested it and it isnt all over the place anymore but it thinks the maximum power point is at 30v and it simply isnt. The maths says it is at 50v. i have been using it for a year at 50v and that has giving me the most power. (I have done endless testing) But for some reason the blue solar controler seems to think the maximum power point is at 30v My question is why? and has anyone got an ideas? It will sometimes do a sweep and the voltage goes up and as it does the wattage produced goes up to. but then it just goes back to the 30v again. at 30v i am loosing alot of my efficiency because that relationship between nozzle velocity and rpm is off.

Thanks for any help.

MyPv Ac-Thor AC coupled off-grid system settings

Hi All,

I'm planning off-grid system with PV and wind turbine. Based on the initial research I think that MyPv Ac-Thor is able to work as a dump-load for the wind turbine. I would also like to include a hot water boiler as prime excess power load.

I found this page https://www.victronenergy.com/live/actor_offgrid but there is no information about how to configure AC PV Inverter.

If I "define Frequency start value 50.1Hz and the Frequency end value 51Hz" in Quattro and Ac-Thor my guess is that AC PC inverter should have some offset e.g. start 51Hz end 52Hz. If all three have the same range PV Inverter will lower it's output so there won't be excess power for Ac-Thor, am I right?

I would like to use dump load only for wind turbine after boiler reaches target temperature. I'm not sure if this can be achieved using only one Ac-Thor.


Two units with following configuration seems to make sens:

1. First Ac-Thor 50.1Hz - 51Hz -> hot water boiler

2. AC PV Inverter 51Hz - stop

3. Second Ac-Thor 51Hz - 52Hz -> dump load for the wind turbine

Am I missing some better solution?

Thanks for your help!

AC connect 3kW wind turbine Victron Quattro System

I have a Off-Grid Quattro 10kVA with AC Connected 3kW Fronius Primo solar inverter and 4kW of solar panels. Frequency shift is used to manage battery overcharge. System works great in summer but we are expanding for winter with additional solar, and a wind turbine. We will AC connect an additional 4kW Fronius and solar array. For wind, we are installing a 3kW 60V AC turbine that will rectify to 48V DC and this feeds to a grid tie wind controller/ inverter (China Supply) that will synch to the AC Bus. The controller will dump power to dump resistors to protect the turbine from over speed/ voltage/ frequency.

However, i am concerned the Wind controller inverter will not spill turbine power (trigger dump resistors) when the AC Bus frequency is shifted by the Victron Quattro (High batrery voltage). Logic tells my the inverter would disconnect on high AC Bus frequency and send all power to dump resistors, though I cant be sure and manufacturer info is sketchy.

My question is whether it would be possible as a back-up to use one of the quattros Programmable relays to trigger when the AC Bus frequency is shifted to say 53hz. In this way I could trigger dump resistors to spill wind turbine power when it is not needed for House Load or battery charging.

Problem with Victron MPPT in parallel with wind controller

We have the following 48V Victron setup:

  • Multiplus II
  • 150/35 MPPT
  • CCGX
  • 48V, 260Ah SLA array

As an experiment we are trying to add some wind power to keep the batteries topped up at night and in bad weather etc. The wind controller unit is setup to have a higher cutoff than the Victron and during testing we are putting about 4-5A into the battery array. The unit is simply wired in parallel with the DC bus.

The Victron MPPT seems to behave as expected as it approached the set-point (current backs off to less than 1A) until it switches to float mode.

What appears to happen when the Victron switches to float is that it gets confused by the other charging source and switches back to bulk charge mode. This is then dumping the full 35A into the battery and taking the bus voltage up to ~55V, until we pull the plug to stop it.

So we are wondering if there is something in the MPPT configuration options that would enable us to stop the Victron from behaving like this

I could put a 600V to 120V step-down transformer between the hydro generator and the Quattros but this would reduce efficiencies.
