I know I'm going against convention but I wish we could start talking about energy in joules or at least watt hours instead of amp hours. Amp hours were a nice convenience when everything was 12v but as 24v and 48v systems get more common having comparable units would be nice. Still a pretty awesome system for that yurt.
Yeah, amps mean nothing. And even more i have a personal problem with a unit of energy having hours in the name, it makes it too confusing for the everyday joe, watts should be the measurement of energy and watt hours the measurement of work done in an hour, just like measuring liquids is just litres or gallons and then litres per second is the rate of flow. Anyways thanks for coming to my ted talk.
You are probably losing about 20-25% of the power on that long run. If you moved your inverter / batteries to the generator and send 120/240v up the 1000' you would lose much less. Another thing you could do is to step up the AC voltage at the generator end with a step up transformer. The higher the voltage the less losses you have. I think that charge controller can handle over 120V DC of input. The rectifier would increase the AC voltage by approx 1.44X
If you have to cover distance you want the batteries, charger and inverter close to the point of use to ensure power quality. There's a reason the transformer on a grid system is right next to the building not 1000 feet away, you're gonna get voltage drop/losses over distance and you manage that by putting your regulation device close to the point of use for stability. And as a plus this guy doesn't need another building to house his equipment.

250w is enough to power most things that do not create heat in a house! Maybe more. It's like what, 6kw per day? (Minus losses). I would love to have that!
24/7/365 250watts adds up quickly. Like said, the inverter supports a generator so worst case if he loses the water pressure he could use the standby generator
I'm not sure if I would use LiFePO in place of the Pb-Acid being that Lithium batteries cannot be recycled or reconditioned but AGM lead acid can be. I guess if I was running off-grid I would still want another system for backup and that would be a generator of some kind, and if anything, combined heat and power offerings from say Yanmar, Cummins or Honda or even a steam-based system, especially in Winter.
Lithium batteries can and absolutely are being recycled at scale - here in the UK anyway. We have collections at all supermarkets and the materials are put back into the minerals market. The US has Redwood Materials doing similar.
he should really think about lifepo4 because agm have like 60 to 70% real capacity (compared to rated) after fully charged....and they need 110-120% to fully charge (around 85% charging efficiency), so u lose 20% of power u put in and another 10% extra when want to "take it out" meaning in total when u put 1000 watts in , you will have 700 max 800w out + they last only 500-1000 cycles before they start to fail (faster when to warm) , need constant charge to last that long and they discharge on itself overtime .....BUT...are pretty safe Lifepo4 on the other hand will have 100% rated capacity (or more) and will last for at least 10-15 years (depending of the quality even longer before u need to worry) --- most good lifepo4 start to lose capacity after 6000-8000 cycles but will last waaaay more - they will just drop in capacity faster after that in each cycle .... only 2 disadvantages are price (but right now similar to agm if we talking DIY pack) and are not as safe as agm if u overcharge / puncture them Also should be good idea to have higher voltage on the line for less power drop (i would make a hut to store battery pack and send 230v to the hut + use wifi etc with app to monitor it)
I would think that maybe a leaf guard, (used for rain gutters) would also work. Very nice set up, how cold does it get, do you have any freeze issues in the winter?
I'm not an expert by any stretch of imagination. I seam to have read somewhere that lifepo4 batteries can discharge at low temps but need to be above 32f to accept a charge. Need to keep the batteries warm or get "self heated" batteries.
@@TeaBagginsMcGee You need a circuit that reduces charge rate at lower temperatures to avoid damaging the battery. Charge speed should be reduced to under 0.1C under 32F and to under 0.05C under 14F. To be fair, if you insulate your batteries well enough then you shouldnt need a lot of power to keep them over 32F. And as far as I know this is mainly only an issue for charging.

Is this pre- or post- Helene? How did it fare thru that nightmare?

That might be true! I think the power drop was less of an issue compared to having a 1000 foot walk to check on the electrical equipment.
@@DIYVolts Indeed and its likely he has more than enough power anyway given his lifestyle. A potential of 6KW per day in the summer can be plenty.

What’s the pressure at the end of the Y pipe with no turbine running?
24/7/365 250watts adds up quickly. Like said, the inverter supports a generator so worst case if he loses the water pressure he could use the standby generator

Cool setup. 250W continuous is no joke. A residential fridge uses less.
With battery storage this system supplies all the power Eric needs for the yurt.
A residential fridge isn't usually running. They normally use 1-2kWh per day.
If North Carolina Department of Environmental Quality finds this video they'll shut him down.
what regulations is he violating?
Seth from land to house?
nice, just add sea auto level power regulation perfect everyday.
he should really think about lifepo4 because agm have like 60 to 70% real capacity (compared to rated) after fully charged....and they need 110-120% to fully charge (around 85% charging efficiency), so u lose 20% of power u put in and another 10% extra when want to "take it out" meaning in total when u put 1000 watts in , you will have 700 max 800w out
+ they last only 500-1000 cycles before they start to fail (faster when to warm) , need constant charge to last that long and they discharge on itself overtime .....BUT...are pretty safe
Lifepo4 on the other hand will have 100% rated capacity (or more) and will last for at least 10-15 years (depending of the quality even longer before u need to worry) --- most good lifepo4 start to lose capacity after 6000-8000 cycles but will last waaaay more - they will just drop in capacity faster after that in each cycle .... only 2 disadvantages are price (but right now similar to agm if we talking DIY pack) and are not as safe as agm if u overcharge / puncture them
Also should be good idea to have higher voltage on the line for less power drop (i would make a hut to store battery pack and send 230v to the hut + use wifi etc with app to monitor it)
Seth, Is Land to House LLC going away or is this a second channel for you?
I would think that maybe a leaf guard, (used for rain gutters) would also work. Very nice set up, how cold does it get, do you have any freeze issues in the winter?
The temp in that area does get down into the lower teens in the winter. Because the flow rate is around 200gpm it does not freeze easily.
So 4.8 kWh per day. Useable for such a small hut
Yes and that is in the summer. In the winter the power goes up to 400w when there is more water flowing.
That is a typical consumption for a two person apartment. (Without heating) It is plenty!
LiPo prob wouldn't be good there. it gets cold in the winter
It's Lifepo4 nowadays. ;) And they can work normally down to -20 C
@@dnnises when they have a heater right? the chemical makup of that will break teh battery if you try to charge below freezing?
I'm not an expert by any stretch of imagination. I seam to have read somewhere that lifepo4 batteries can discharge at low temps but need to be above 32f to accept a charge. Need to keep the batteries warm or get "self heated" batteries.
@criticaltemperature3343 that's what I read. I do admit it was a couple years ago. But new higher quality pack come with heaters.

He could do wind power
Hydro is constant.wind is not,unless one lives in a place with constant wind,which is not really a place I would want to live.......
He needs a burp pipe
why, do you have gas?

200W is LAUGHABLE small. Sorry NO.
I'm living on 100w solar, 6 lead acid batteries. All needs upgraded but the cost I can't come up with.
Maybe, but it is free 24/7 charge
