@@derrickjohnston-iq3en yup it would

true u get what u pay for

yes only if you have a midnite classic 150 controller you can run 24v turbine in 12v battery mode.because its a true mppt c c.the chinese c c are volt specific cause there there not a true mppt they are voltage specific and will not work

@@offgridgarage Thank you very much for your answer. It is really appreciated!! I had hoped for another answer because the midnite classic is very expensive. But I am also happy that I haven't wasted my money on a nonworking mppt. (I have not bought the turbine yet!) I like the idea of having a 24V turbine on a12 V battery to improve the low wind capabilities. But maybe I will have to accept running 12v/12v to keep the cost of the project down...

yes

In my testing these wont work on larger turbines.you will need a midnite classic charge controller for wind turbines

the old add on screen room came with it.i cut that roof for the bunk ends folded over the edges used a box stapler stanless steel staples and put reflectex in between the layers

i cant say for sure but i would say yes it would work ratter well for micro hydro i cant see why not.

you will not be disapointed but u need the rear sattelites

hello steve on the i1500 48v turbine with 24v battery bank im running 4 over 8.remember the classic 200 is mppt converting the higher voltage to higher amperage the same as solar does.voltage is 4 8 12 16 20 24 28 32 36 40 44 48 52 56 and 60 amp are 30 38 46 54 62 70 78 86 94 102 110 118 126 134 142 and 150 its a strait curve.specs on the turbine are 30 amps max 150 v ocv.so i doubled the amps in my curve as the battery bank is half the the turbines voltage to get full potential whats you battery bank voltage and your turbine specs i will give you the best curve

this bike is a a power house the most roudiest bike ive ever drove.giver a shot in 2wd it will send the bike sideways on dirt roads.your lookin for power this is it when needed.trail riding is smooth too if easy on the throtle.if your lookin for power look no further its fast too be careful this bike will kill you if you dont respect it. its a bad ass power house unreal.

the idea is to have a fully charged battery.turn on air conditioner with radio is only 380 watts so create more power than you can use.if the sun is shining and batterys are full charged it simply stops taking a charge.as you know pop ups get hot in summer like an oven if you cant use the charge when full charged turn on free air conditioning an radio an crack a cold beer off the grid is priceless.

you can look it up online

He may need not get more 3amp, but 3amp multiple by 600v is 1800 watts, which is plus or minus 33 amps at 48v

the bus bars come directly from the batterys bypassing the bms from lvd.ts 60 direct from batterys bypass bms as well useing the rectifier gives higher false readings if turbines spinning up.so i connect directly to the batterys for those reasons.all cc have been calibrated as well so not to trigger dump load falsely.

i have not tried that controller with solar but yup spot on 24v 800 watt.top voltage is 80v so if your panels exceed that togather in series ocv it will destroy the controller.however 2 400 watt panels in paralel should be fine.but i have not tested that .i would wire 2 in paralel and be watchful the first sunny day

yupper still going strong lol.getting ready to fly the new i2000 soon will have more data to come shortly

The i2000 is 48v only I think. Are you going to run it into a 24v bank ?. Should do really well. An alternative to MPPT, albeit imperfect is to run into a lower voltage battery bank. So you'd get low wind generation. All very interesting!

48v turbine 48v battery lifepo4 using a classic 250 cc and ts60 for dl but im still up in the air as to 3 blade or 5 @@nhikoid

@@offgridgarage strongly advise 3 blade. Tried 5 blade which starts spinning earlier but with notably less RPM. Far better output with 3

ya i too am a 3 blade fan so i will swop the i 700 3 blade to the 5 blade was feeling lazy but i absolutly agree @@nhikoid

you can use a 3 phase bridge rectifier with a 48v turbine on a 48v battery bank if your using flooded lead acid batterys ok with a dump load.but not on lithium batterys safely.

@@offgridgarage Thanks Reggie , thats exactly my plan , i have sealed lead acid batterys and three single phase Rectifiers ( works out cheaper to use three single phase ). Ill keep you posted how it holds up when i get it up , its on the side of a mountain in the west of Ireland so we shall see .

they are false labeled some dont work rate out of the box others are wrong voltage buyers beware

turbine will free wheel and self distruct.diversion controller is important.i700 will hit ratted speed 700 watts just need the wind to drive it.

in higher winds it can hit 800 watts and will but needs 50 kmh wind

@@offgridgarage ye I have some experience with that 😂 my controller started sending 35-50v to my 12v devices, an expensive mistake, that's a nice battery bank you have !

with the 3 longer blades 107 cm the i 700 best day was 2 kwh per day for 2 days in a row using the cheap chinese controller 24v at my sons camp.the charge controller is still going strong lol

@@offgridgarage 107cm damn that's pretty long, I'm running 750mm only and 650mm, I think I get more wind that you most I've seen out of my "500w" was 5.2kwh in one day but it was a very very windy day.

it is only good for small turbines 400 watt 12v max 800 watt 24v max ceiling voltage is 80v so it is not a true mppt will not work with bigger turbines on startup it will lock them out meaning not allow start up

I bought this exact mppt controller and it was trying to shove the input voltage from the turbine with no mppt control into the battery and if it wasn't for the BMS protecting it from overvoltage I would have had a fried battery, specs say it can handle up to 80v on the 3 phase turbine side but it wasn't being regulated to 24v on the battery side. Had to return as it was clearly not quality controlled and dangerous - not to mention when it worked for a brief time it performed worse than a bridge rectifier setup.

​@@offgridgaragefor me it didn't even handle a 48v 500w turbine

With a rectifier and diy controller you will have the comfort of knowing that your turbine is always directly connected to your battery bank so that turbine voltage is always clamped down to some extent. With those cheap ebay/ali/amaz controllers you just can't be sure what's going on and could end up with very damaging voltages. Maybe there are good ones out there but there are so few subjective reviews of these online. I hope to be persuaded otherwise cos MPPT is the best method for optimising performance.

@@DomX2008 i havent tested the 48v with that charge controller.the 48v one i ordered was set back to 24v settings and tested with the i 1500 it locked out the turbine from turning so i sent it back and got a midnite classic.as i was to far to stop now.to be safe with lifepo4 i will only use mppt chargers and a dump load installed.i dont think the bms will handle the bridge rectifier long term as its unregulated

you sure can if using a bridge rectifier it will work just fine.however an mppt charge controller can yield 5 times more output.most importantly be sure to have a dump load in place to protect your turbine and your batteries

@@offgridgarage Thanks for responding - much appreciated. I already have a Tristar 45A Diversion Charge controller which is mppt and 500W 48V dump load - installed for the 200W VAWT turbine I am replacing - but those may need upgrading for the i700 I guess.

yes it will 400 watt 12v max or 24v 800 watt max

I cant see why not but an educated guess would be a lost 50 percent i cant say for sure as havent tested that theory

My guess is yes at 50 percent loss

24v into 48batt It would work but your cut in voltage would be too high. Lots of spinning in good winds with no charging. Would work in high winds but you'd miss out on a lot of power gen. Wouldn't advise you do this.

I was going to subscribe and see if he had further updates. I do not see anything yet - 5 months later.

cant live with them cant live without them

good to know that i too get those same results with 48v i 1500 on 24v bank however i was wondering how much top end i was loosing but in my lower winds there is no no top end so i cant get what not there was interested in seeing more top end in my testing with the 48v i 2000 on 48v bank will answer my own questions.lol and i will post it when its flying.thanks for the update

@@offgridgarage just a thought...when your turbine raises battery voltage to "full", does your BMS disconnect the battery. This would make the turbine freewheel with zero loading (not good at all!, especially if the BMS waits for ,say 10 seconds , in a storm before reconnecting). So you'd need to have your dump load controller set to start dumping excess current before the BMS disconnects. I'm on lead acid but thinking of upgrading to lifepo4 and this is something I'm researching. Maybe a safeguard could be a small cheap 12v "slave" lead acid with a second volt sensing relay (£10 to £12, ebay) normally open, but would close to fire a second relay to start dumping current.

@@nhikoid that is correct solar stops at 27.4 wind continues on till 27.6 tristar 60 dumps all power through diversion load a 1500 watt heater holding batterys down to 27.6 so the system is always loaded.i dont trust ssr but tri star 60 pwm are bullit proof

@@nhikoid i had bad luck with ssr i dont trust them ts 60 is bulletproof

the holes from stator wires put at bottom in case water does get in it will pass through

getting 1.5 kwh per day in low wind while still testing.the 700 is almost keeping up with the 1500 but its higher elevation suprising results lol

i too had the same problem test it with a 3 phase bridge rectifier you will see that controller is braking the turbine not allowing it to spin up.you need a differnt mppt charge controller

@@offgridgarage Do you have one you recommend for life po4 batteries?

@@armandogdgdgh3163 all though expensive i will only use midnite classic 200 mppt charge controllers for wind there worth every penny.the sl unit is for solar only be sure its not the sl model.these controllers are the best ive seen an will protect lifepo4 batterys when set to the right values.you can gain up to 5 times more kwh.

these charge controllers have a 80v max ceiling voltage however i had the same problem in a 24v battery bank it would not allow the turbine voltage to exceed 30v on spin up or cut in than applies the brakes.these controllers are only usable with small turbines 500 to 800 watts max that is my findings as well.i used another charge controller for the 1000 watt turbines or higher.false labeled from china.they simple hold back the turbine to protect the controller

yes you can run them to bus bars without problems thats how i like to do it as well.just be sure the wire size is correct to handle it

I am having the same problem with this charge controller. I haven't used the original charge control because i rather the digital reading but am going to try it tomorrow. Only putting out 1to 15watts max

ya the speck voltage and ampage is from ista breeze data.so the classic convertes the higher voltage into ampage nice controller

That's some great information right there! Are you using only a rectifier to feed the energy from the 3 phase AC 24v turbine directly in the 12v battery bank? I'm considering getting the 24v i1000 from ista breeze for my 12v battery as well. The cut in speed and rotor diameter is what's killing the output of my other 400w smaller turbine; I can get close to it's rated output with a commercial leaf blower or an usually windy day (25-40 KPH) but get zero power output as the wind in my area is constantly right below the cut in speed (10-15 KPH) . Thanks!

@@samuhell14 Direct from rectifier.

Should add, I think the i1500 has a nicer power curve than the i1000 or the i2000 for lower winds. That in combination with using the 24v model with your 12v bank should give a nice early cut in.

Thank you very much for the clear answer! The main reason I can't really go higher than the 1000w model is the electrical installation itself, I went overboard with 6 AWG wire for my punny 400w turbine but with the Ista Breeze I'm pushing the ampacity of the circuit and voltage loss will be a bit over 5% with 50 feet of wire. And frankly, I don't want to deal with unearthing the electrical conduit and fiberglass insulation in the roof again :3
