Like your information. Only thought that comes to mind. Mounting electrical terminals on to wood have risk. Since humidity, accidental roof leak or even a hard driving wind/rain storm, can get the wood wet. Not sure if you are in a desert, but I could never do this.

[@GBear]

Welcome aboard. Yes, I am in a desert, and the battery room is weather proofed so rain won't get in. Also note that all wood mounted connections are low voltage. (12vdc) the 120/240v stuff is all in electrical boxes and conduits. Thanks for your concern, though.

[@miguelsalami]

You can connect your dump load wires to a hot water heater heating element to heat water instead of sending it to a heating element that causes more hot air near the electronics & wastes energy. Thanks for sharing your setup & knowledge.

[@GBear]

That's true, but as I said before in prior comments of the same subject, I live in the desert and don't need any more hot water. My tankless propane water heater only is used a couple of months a year, and very little at that. The heat produced in the battery room, is usually in the winter and helps keep my batteries warm through that time, making them more efficient.

[@miguelsalami]

@@GBear Gotcha but for someone wanting to go Solar & heat their hot water tank for free using the dump load & a different heating element in their hot water heater works quite well. Speaking of batteries have you done any vids on battery maintenance for lead acid types?

[@GBear]

@miguelsalami Yes, before I actually moved out here, I had made a hot water barrel heater for my outdoor shower, but once I got here, I realized it was a waste of time. As for an actual video dedicated to battery maintenance, no I haven't. I have mentioned topping off with distilled water every couple of months, cleaning terminals, etc.

dumpload controllers with solid state relays SSR have a longer service life , well if the solenoid is switching on and off Alot because the turbine is in a good wind location the mechanical relays can get stuck on due to the result of endless arcing so many point out, Very Good video for beginners, one of the best ive seen.

[@GBear]

Thanks for the input! Yes, there are better systems, but keeping a mechanical solenoid cool is key to longer life. If you have the money, go with the relay unit, though.

[@stoneledgetinyhouse]

The dump load controllers with SSR you speak of are they the ones on the market that only use the AC 3 wires coming in then rectify & control the output to either battery or resistor/dump load? I am trying to take DC from a DC motor wind turbine (DIY) & divert it from the batts once full.

[@GBear]

A 3 wire PMA needs a rectifier to convert its ac output to DC, DC can then go to the battery and a digital diverter will keep the battery from overcharge by diverting excess to a dump load resistance.

Thanks for the video, I have been trying to get info on how to size the wind generator. My off grid system has 3x100 amp lithium battery and 2.1 kw max solar... I need extra when no sun for days but I have plenty of wind.

[@GBear]

Welcome aboard Ed! Ok, let me simplify the sizing for you. Since wind generators seldom put out their rated value for a consistent time due to fluctuations in the wind, get the highest rated one you can afford. You'll still need either a diverter or a good Midnite classic controller, the latter being the better choice. Not all controllers can be used for wind, but the Midnite classic is designed for it and is very efficient at it. Take into consideration when going with wind power, max output at what wind speed? Also, 3 bladed units are a better design than 5 or 7 blade units, but size and shape make a difference also. The tower or mast height and strength. My little KT5 PMA has pulled a 300+ pound concrete anchor out of the ground in 60+mph wind. Guy wires need to be steel rope able to handle 3000-5000 lbs of stress in high winds also. Then consider access to the PMA for maintenance. Simple things like bird poop can throw the balance off, causing excessive wear. That brings me to another thing...be sure to check your hub and blade balance before installing them on the PMA for best performance and output. Lastly, consider where the PMA will be located and the distance from the battery bank. Wire size and PMA vs PMG are affected by that distance.

@@GBear great vids g-bear. My question is more about solar. I’m still stumped on how to divert solar power after batteries are charged. Like to heat water. Is there a simple diverter system that can be triggered by a timer or voltage that doesn’t involve using the batteries. One person mentioned it being necessary to have a switch or relay before the charge controller to prevent micro cycling batteries. Im still very new to all this. Thanks

[@GBear]

Hi Spot On. Welcome aboard! Yes, there are ways to divert excess power to heating elements. Below is a link to one type, but the element included with this unit is for air warming. You would need to buy a water heater element in your voltage and subsitute it for the air heater element. I'm not promoting this particular charge controller, just showing you what is available. amzn.to/3yzDi8s You didn't mention the size, output, or even how much wind you get at your location, so I couldn't be specific on what you need or should expect from the setup.

@@GBear I appreciate the help, and thanks! it’s a small solar setup for a shed. I’m really just looking for direction on the concept tho. Interesting charge controller! i just want to make sure that the dump load doesn’t pull from the batteries and micro cycle them as some KZbinrs mentioned some will. Do this “d” terminals carry the power right from the panels or will they pull from batteries? I haven’t seen charge controllers with a “d” symbol on them before

[@GBear]

@@marceloadrianmendodelacruz5451 yes, there are hybrid controllers that handle both wind and solar. I prefer not to use them from experience. I had to cycle through the controller to distinguish between which was producing what. By separating them out I am able to see those numbers at a glance.

[@helpmikey]

curious will it not damage the battery if you feed the output of the rectifier direclty to the battery ? . Again I am not expert on this just asking to expand my knowledge. do you still need a voltage regulator to match the proper charging voltage of the battery ? feed the output of the rectifier to a voltage regulator or PWM or charge controller ? thanks

[@GBear]

Welcome aboard! First, let's start with the basics. You should not attempt to charge, let's say, a 12v battery bank with a 24v turbine. Think of it like you car. You wouldn't replace the alternator with one that outputs higher voltage, right. Now, yes, you 'could' do it using a specific charge controller, a transformer, etc., but it would complicate your system and life, while costing you more. As far as connecting the bridge rectifier straight to the batteries, yes it will damage the batteries unless you also add a 'dump load diverter' to handle overcharges. You could also use a Midnite Classic charge controller set up for wind power conversion, which is the best option, as this allows you to fine tune and adjust the input for best efficiency.

[@pulesjet]

Good Informative Video Sir. I have both in the works. 12V and 24V . The wind system being 24V. Most likely will be going with 24V only at some point. No Obstructions here so I can get away with the turbine only being 10Ft above my roof line. The main disadvantage of using a DC 2 wire Wind Turbines is DC voltage they produce requires heavier gauge wire and does not travel distances as well as AC or Three Wire systems can. They work for stuff like boats but for home use Best to just avoid the things. Well it's Semi Official. ​Wife works at Wally World and they was informed today to expect the shelves to start being short. The warehouses are feeling the pain. So if there was a Chines product your in need of at Walmart you might want to think about grabbing it.

[@GBear]

[@richardschofield2201]

Enjoyed the video. One thing (probably of many) that I haven't figured out yet is how is the voltage from the pma regulated. I assume the voltage will vary with wind speed but you need a nice steady 14.5v to charge the batteries.

[@GBear]

Welcome aboard. Yes, the voltage is quite variable from a PMA due to wind speeds. The best way to control it is through a Midnite Classic controller after the bridge connector. I still have mine 'old school' style where the bridge rectifier connects to the battery bank and a dumpload controller monitors voltages in the bank and dumps it if it exceeps capacity. I was going to upgrade to a Midnite Classic controller bit the economy made finances go south.

[@meltonenterprises6761]

I built my own vertical windmill with a treadmill motor. Now I'm just here to see about the control system for the battery bank.

[@GBear]

You'll need to determine the treadmill motor output voltage and wattage, and whether your output is AC or DC. With AC you'll need a bridge rectifier that not only converts the AC to DC, but steps the voltage down to your usable battery bank level. You can't charge a 12v battery with 60 volts DC! With DC (PMG) you will also need a step down transformer, but not a bridge rectifier.

[@GBear]

Oh, and welcome aboard!

[@meltonenterprises6761]

[@evil17]

Good vid & explanation of ur system G Bear. Wouldn’t it makes sense to use ur dump load to make hot water or at least a pre-heater for a hot water system, but use ur excess solar power from ur controllers as well, as soon as ur batteries are full SOC have the controller divert any extra power to ur hot water system. I have a 50ltr hot water system that operates this way on a stationary 40’ bus, a 24v system, 3kw AIO inverter, 2.5kw pv panels & 10 kwh lifepo4. I can run microwave, 2.5kw split air con, H/W system, everything off Solar & heat water for the family of 4 showers daily while fully charging batteries. I have a 24vdc multi power element (300w, 600w, 900w capable) for the H/W system but never fitted it as I use the inverter with a AC voltage/dimmer control so I can adjust the output to the 240vac 1800w element I installed previously, instead of the 3600w element it had standard. I can use the controller to vary the power usage of the H/w system if its cloudy or for other reasons. For my house I have a 5kw AIO 48v system with 10 kwh of pv (grid tied) & 30 kwh of lifepo4, I only use about 20%-25% battery SOC a night on either system generally, higher voltage systems are much more efficient if ur going to use an inverter, & use a step down (or up) converter for lights & light loads to save on wasted inverter idle power usage. Lifepo4 batteries are a game changer now days in so many ways & using a decent shunt ,means you can know very accurately how much power is going in, out & still available. They were PWM controllers u were trying to think of , it stands for ‘Pulse Width Modulation’, but Im sure u know that. Cheers

Hello G Bear, thank you for the very informative video. There are so few of these videos going into wiring details. I had a few questions as we are also installing a turbine, but this is in Wales UK. I am learning as I go along so please bear with me. The setup is a 5Kw turbine, standard three-phase (three magnets), 300 yards from the house. 48v batteries with a 5kw controller. I have laid 2 x 10mm cables from the turbine (instead of 3) does the controller now have to be located at the turbine site as it has a three-cable ac input? Or, could a rectifier be put next to the turbine to convert to the two cables? Any advice is appreciated, Dan

[@GBear]

Hi Dan, welcome aboard! Since 2 rectifiers can't be used on the same PMA, you would need to mount the controller at the PMA. The problem is, if you do that, then you need to use larger diameter wire from the controller to the load. The reason we choose a PMA over a PMG is to save on conductors (wiring size). It looks like your best option is to run a third wire from PMA to controller.

[@digitaldreamer5481]

GBear, another alternative to dumping your excess power, feed that extra power into a secondary 14 volt battery bank by using a combination of 6v & 8v golf cart batteries, which requires more current for charging. I’ve been using BatteryMINDers 2012’s for all five battery banks except one AGM bank that uses the BatteryMINDer 2012-AGM model. My golf cart batteries and AGM’s are between 10-15 years old and only need to add acid once a year. I use two banks for Ham radio that requires 13.8 volts. BTW, a PWG also works as a pulse/desulf charger but I like that BLS-12N and I will see if I can buy a couple of those.

[@GBear]

Welcome aboard! I do have plans for a second battery bank, but was thinking more along the lines of 48v as a backup.

[@fishhuntadventure]

Umm you should never shunt of dump into anything that could run out of capacity. You could kill the turbine or your batteries or both or all three: catch things on fire. (10:20 looks a little fire risky to me)

[@damianroth4265]

@@fishhuntadventure won't the dump load controller just divert the power when the main battery bank is full?

[@GBear]

No. It will turn on when the battery bank is over full, but the AIMS and the Midnite Classic also prevent overcharge, so the dump load never activates any more.

[@damianroth4265]

@@GBear GBear, thank you for the reply… it seems your video didn´t just enlighten me, but also a huge pouch of people!

[@tadhuey5051]

Great video!! I'm in te .idle of a diy turbine with a dc motor. You helped a lot. may I ask... the turbine obviously produces different amounts based on the strength of wind at the time. Does this matter for chargung the battery? Like if its putting out 200 volts into a 12 volt system will that be ok? (I do understand it can over charge so it needs the dump load) I'm more curious if there's a range of voltage or current it must fall under so it doesnt damage the battery or does this only matter for the gauge of the wire to be able to transfer and not burn up? Hopefully that question is understandable. Anyway ty very much.

[@GBear]

Hi Tad! Welcome aboard! Normally, a turbine is purchased to match the voltage of the battery bank, ie; 12vdc PMA/12v battery bank, 24vdc PMA/24v battery bank, 48vdc PMA/48v battery bank. The voltage output of the PMA is very important! If your PMA produced 100v and was connected to a 12vdc bridge rectifier it would blow up. Remember, a DC bridge rectifier is comprised by connecting 4 diodes in series to change the alternating current to direct current by forcing the 3 input wires to all flow in one direction. This produces heat, and lots of it, that's why the rectifier needs a heat sync. The major downfall of small DC PMA'S is they may start producing electricity at low wind speeds, but that voltage is too small to charge a battery bank. To produce the 13+ volts needed, a 12v-1685 watt PMA needs about a 15mph wind. This means it is pretty useless to most locations/applications, as not many places have constant 15+ mph winds, 24/7/365. I hope this info helps.

[@anthonypape6862]

You need a charge controller like the midnight classic in between your turnbine and battery bank It goes Turbine >rectifier>charge controller>battery bank>invertor>main breaker panel.

Hi Thanks for all the tips, wondering if you can explain how you spilt the dual solar panel loads due to the size of the controllers Thanks Ross Tga NZ

First, Welcome aboard! So, I connected 2 of the 305 watt panels in series, (positive to negative), and did the same to the other 2 of the 305w panels. This doubles the voltage output from 40voc to 80voc per set. Then using a 2 to 1 MC4 splitter I connected those two sets in parallel, (positive to positive, negative to negative), this keeps the voltage at 80voc, but increases the amps from approx 10 amps to approx 20 amps. Then I up the gauge of wire from 10ga to 8ga from the splitters pos and neg directly to the Midnite controller which has already been connected to the 12v battery bank. The VOC input can peak at 80voc/20aoc, just over the 50% mark the Midnite 150 can handle, but the MPPT balances it to somewhere around 65v/25a input, meaning I can add another 4 of the 305w panels connected in the same way and safely stay within the allowable parameters. Then I connected my old 100w panels in series groups of 4 each, and parallel 3 strings (groups). I brought the pos/neg leads times 3 into 2 bus bars, then a single pos/neg to the Renogy controller which was also already connected to the battery bank. The Renogy has a max input of 112voc which I stayed under, and the amps are around 20 per string (group), so approx the same input as the 305w strings. I hope that helps you understand, but if not, let me know and I will do a walkthrough video for you.

Welcome aboard Fred! Thanks.

[@khalidatiq8518]

Very informative Thanks for this. Question.. What is the use of pma and pmg

[@GBear]

Welcome aboard! A PMA (3 wire) is an alternating current device which requires an external rectifier to convert the alternating current (AC) to direct current (DC) for connection to the battery bank . A PMG has a rectifier built in, so only 2 wires come from the unit, directly to the battery bank. The PMA can use smaller gauge wire than the PMG which saves money, but also having the rectifier built in means you would need to bring the PMG down to replace the rectifier if it burns out.

Where did you get the hinge for bottom gas pipe

[@GBear]

Actually, I found it in some dumped junk in the desert.

[@themadmailler]

Question. I'm looking at the KT5 on their website, they say in high wind gusts it can produce up to 68V peak on the 12V model. It looks like their rectifier is rated to 1600V, but what would happen to the batteries? would it just trip the load dump solenoid?

[@GBear]

Yes, but solenoid dump load systems are no longer used. Digital diversion units are the new wave. I live in a high wind area, but have yet to see more than 60amps and 880watts, and that was with 45mph winds. That's 14.6v. I was told the same thing as you, but can't figure out what they are talking about. A 12v PMA is a car alternator, and it would never put out more than 14.7 volts, even if you were driving 120mph with 5k rpm on the engine. I think they hype the product to sell more product. I bought their meter unit to monitor output and it failed in a short time. They gave me all kinds of crap about how it was my fault, etc., then it mysteriously got lost in the mail and I was out the money and the meter. I bought a Chinese meter and it has been working fine ever since.

Welcome aboard, Noah! If you live inside city limits, they usually aren't allowed. They need to be high up, especially around multiple buildings that would affect air flow.

[@GBear]

@Noah Riding The higher up you put them, the better they work. Solar is a much better bet for camping, as you don't always have wind, but the sun is pretty reliable. Turbines are supplemental providers, and shouldn't be relied on as the main source of power. After all, who wants to camp in 40mph winds?🤔

[@bobdobalina838]

Great stuff, thank you! so basically the power from wind is going straight into the batteries ( disregarding the rectifier) not using something like a charge controller like the solar does, correct? Would this same setup translate to hydroelectric, no? (Pelton wheel being spun by water) lastly, where did you get that display showing power and voltage? Or what did you Google for?

[@GBear]

Welcome aboard! Yes, 3 phase AC power comes in from the PMA (turbine) goes through a bridge rectifier to make it Single phase DC, then through the "high precision wattmeter", then through a breaker to the batteries. Then a dump load unit or digital load diverter is applied to the battery bank to prevent over charge.

You should mention with the solar wire the gauge could be less if the panels are wired in a series vs wired in parallel (more amps require thicker wire vs more volts and less amps and letting the mppt controller convert the higher volts to amps at the controller)

Hi Graham, welcome aboard. They need to be connected to the bank at different locations, and should be set with the same parameters. Also, only one should have the 'equalization' feature turned on.

I found the same thing when I tried to read the Chinglish instructions. I don't recommend using that controller for your PMA.

Im making a diy wind turbine from a single phase dc motor. Do i need to add a controller between the turbine and battery and if so, what controller should i look at? Thank you for the great video!

[@GBear]

Usually a DC turbine can be connected directly to the battery bank, but first you need to do some tests to determine maximum output of the generator to be sure it is in range for your batteries. Too low an output, your batteries won't charge. Too high an output and it will damage the battery. Using a controller, you will also need this information. If output is around 13vdc, you would charge a 12v battery. If output is around 39v, you would charge a 24v bank, etc. If connecting directly to the batteries, you would need a dump load diverter to protect from overcharge, and an inline diode to prevent backfeed to the motor. A charge controller should come with both features built in.

Hello from the UK. Have you ever tried running a 24v turbine with a 12v battery bank, former forklift batteries 6 x 2v each. I can't find much on it. I've tried this and didn't get any power from the turbine, 15w max. Was brand new. I tried it with the controller and also bypassed that and used rectifier only, again nothing even in strong winds. Would you have any idea if it could be the controller not up to it (I used the one it came with) or it just won't work. Just thought I'd ask in case you tried it. Thanks for this video, very detailed and picked up lots of tips.

[@GBear]

Sorry, for my last response, I read your question backwards. Haven't had my coffee yet.😉 A 24v PMA would have a way to high output to use on a 12v battery bank and could damage the batteries. That would be like plugging a 120v fridge into a 240v outlet. Again, you could use a step down transformer, but not efficient. It is possible that your turbine is not PMA (permanent magnet alternator) and actually a standard alternator that requires electricity input to produce output. In that case, the 12v input would be too low to activate the alternator.

[@hardylioness]

@@GBear ha! No problem. Coffee is fuel, for sure! It was a recommendation from another KZbinr. 500w turbine 24v 5 blades for a 12v set up but I found it didn't output anything. OK, thanks for your answer and analogy. That helps. J : )

Yeah, the one thing to remember with turbines is, If it is rated 500w with a maximum speed of 60mph wind, what they are actually saying is you need a 60mph wind to get 500w. But for basic electrical in wind and solar, you should ALWAYS match voltages.

It also lied about its capacity claiming 32000 watt surge capability, the in fine print right on the inverter it says it won't handle a pump motor 1200 watt surge. Long story short, avoid Chinese made inverters. I have since switched to an AIMS split phase low frequency inverter and am loving it.

I'll need more information in order to guide you correctly, or you can call 877-878-4060 for more info on the Alte prewired system. They can actually configure a system to meet your needs. Note that there are 2 types of turbines. PMA & PMG. PMA is an alternator type with 3 wires, all the same color and needs a bridge rectifier to convert AC to DC before connecting to a charge controller. Also, you need to be sure the size of the turbine output won't exceed the voltage input specs of the Midnite, so you may need the Midnight Classic 200 or 250, full controller, (not an SL).

I enjoyed watching. Please I have some questions

Hi G Bear. I have a question for you. I'm looking to get near offgrid battery storage. At the moment I'm looking at a total of 1000AH in total. 4 batteries 12volt. Set up to give 24volt. Will this be enough for a small house hold. The batteries will set me back 2000€ for the 4. What do you think.. will that be enough to run my home. I would appreciate your input. Thanks Bear! I have watched this video 4 times and sheared it to people who have the same interests. Great stuff!!!

Hi Peter, Welcome aboard. Short answer, probably not. I really don't have enough information to make an accurate comment. I suspect your household items are 220-240 VAC from your monetary symbol. To properly size the battery bank you first need to total the number of watts needed to run all your household items. There are many charts available online to help you size your battery bank and solar size. If it helps any, I run my small cabin on a 12v battery bank made up of 18 each 6v deep cycle golf cart batteries, connected to make 12vdc input to my inverter. I recently added 4 more larger batteries. The first group totals 2007ah, and the second group is 740ah, total=2747 amp hours. This configuration runs all the basics, and will run a window air conditioner in the daytime with the 2900 watts of solar input, but won't handle electric heating units, toasters, microwaves, etc after sunset.

Wel it's a good starting point 1000amp at minimum. Its called: (sonnenschein Gel Deepcycel battery). I have a 3kw three-phase vertical axle turbine (Makemu.it) no solar panels. i guess it's a question of trail and error. Thanks for your support Bear. The smart battery big brands have 8kw battery storage at minimum 5000€. Expensive purchases. Keep safe.

@@peterjoseph2803 wind is good for a back up, but solar panels are king for daytime power.

Dear G.Bears We thank you for your clarity of your videos ,very clear speach of yours ,and properly technical placement of all the aspects concerning what else....Energy. I have one question .We all know that somehow china is the center of our planet for most of the things that we all days we need.One thing that strikes my mind is the Wind Generator issues.They shout 1,5 KW 2 KW etc and there are plenty of videos that they measure their output and the result is so dissapointing to the thechnical world.I really wonder how Not even one [to my knowledge] has not tried to create a wind generator from a truck Alternator which they really have good output but of course need long wings and strong wind.I will continue searching around for an honest wind generator in regards its cost.Also instead of having dump load for the wind generator to drive the cable to the appropriate Resistance of a water boiler so.no energy is being lost cause actually heats up the water inside the boiler. Everybody knows that there are professional people that they construct resistances to your needs AC DC 5 volt 20 volt 100 volt .u just name it.....Best regards.

As someone new to this, with a basic electronics knowledge from school, any learning resources you’d recommend to build up base knowledge on all this?

[@GBear]

KZbin can help along with hands on experience. Welcome aboard!

When you need to replace your batteries do you think you will go with Lifepo4 batteries? They are getting cheaper all the time. Thanks for the video.

[@GBear]

Welcome aboard! Not sure about that. The extreme temps out here are not good for LiPo

[@JR-xw5dk]

If you have some strong young and very good friends an earth bag structure might be an option. Maybe one for the batteries and one for the other equipment. The equipment room could heat the battery room. Eg4 now has a self heated battery, I think it is 13kw and is about $4000. Maybe a suggestion for someone starting out that could be expanded on. Maybe a subject for your new paid channel. We could see some deflation in batteries after we get through inflation going down. Again thanks for sharing.

[@GBear]

@@JR-xw5dk Thank you for the information. I'll at least do my research so I know what I'll be dealing with in the future.

[@JR-xw5dk]

Not anything I have tried but just something I thought about. If you can get the right thickness of wall you might get it warm enough for the winter and then cool enough for the summer. Maybe do earth bag work shops. Get people to pay you to work for you. 😂

[@GBear]

@@JR-xw5dk lol, thanks. I'll keep that in mind.

[@LEETAVES]

i have set up for my office and one set for the freezer and frig. the 24 will be for the air

[@GBear]

Too bad you are on the other side of the country, I'd love to help you with the setup, but from here, I worry about your safety while Jerry-rigging power. Where do you set up your panels? The Gustapo will spot them and throw you in the cooler.🫡😆

[@GBear]

So what are you using for an inverter? You would need separate ones for 12v or 24v. Also the wattage and pure sine or modified sine wave makes a difference.

[@LEETAVES]

@@GBearihave 1500watt pure sign wave for the office i have 1000 pure sign wave for the freezers i have a3000 pure sign wave they are relibles for 24v i have a 25000 i have high dollar charge controllers tristar but don,t whant to mess them up they all have dip switches for setting
