- I tested the plan to utilize hourly ETEX power market prices to minimize my power costs. As power storage I tested the Oukitel ABEARL P5000 Power Station. The 120V MPPT solar inverter turned out to be the MVP.

Today the overproduction is so high that you get paid 2cents to consume even with the high grid costs. I hope for more days like that. Updated the sheet to start at -0.02 now🤩
I heard it from a friend as well, which uses tibber. When I got a good power storage, I'll definitively try my best to save money :)
3000€ - way too much , ridiculous considering i get a home storage with 10 kWh BYD cells for 2500€ + connect a 500€ hybridinverter.
the usual scam cause the cells are unknown and no domestic support.
At the end the inverter will dy and I am screwed.
too much money is in the powerstation business , every yt channel becomes a master powerstation reseller and if I see 2 powerstations in a row on a channel i unsubscribe instantly.
In sweden we have cheap (to produc) and clean power. But I still pay $150-$200 a monthvthanks to europe sets the price. So if sweden exports to Germany i pay the same price as germany. Thanks eu
DrZzs might need your help on his project of a magic 2,4 m diameter ball out of 20000 LED or so which sould be able to project the surface of the earth. Look at his sunday evening (MESZ) live stream about the ATLAS project. There must be a big city hall or so in Las Vegas build out of these - i had missed the beginning and saw only the 3d sketches they had done. He will pick up the wooden support structure tomorrow or so and then start the building. He had been talking about a purchase of 4 power supplies for servers each 1200 W or so.
Hope you can get in touch with him as he had mentioned your channel and the table tennis led walls you had done before and inspired him.
I really like the honest review of your plan including providing information about the limitations of your setup. Some other "influencers" wouldnt have done it this way.
You could double up the solar panels: Giving you two strings of the same voltage but double the amperage. The charger will limit the amperage to reach an input of 1000W. But you will get this for a big portion of the day.
Just picked this up for 1800 USD. Hopefully it works for my use. Thanks!
Just a side note. If you had to actually pay for the power bank, and assuming 100% conversion efficiency at every point, no gradual loss of capacity or efficiency, each kWh stored in the battery costs you about 13 cents over the full lifespan, so that's the minimum amount you need to save on every kWh to at least break even.
the coolest done online since the start of online - bro!
I believe it when they say that the battery is good for 6000 cycles if cycled at say 80/20%.
But these type of power stations have a bad record for inverter failure way sooner when used for this purpose as a house battery.
I think they are fantastic for camping and small off grid cabin use or as a back up for grid loss.
But as a permanent house battery you are way better off buying server rack batteries and appropriately sized inverters. Or even better still, building your own batteries to further save cash :)
5kwh of raw battery is about 900€ - you may should consider building some home battery storage project in a diy edition with pylontech battery and a growatt inverter for example
That's a good price. I'm only hesitant to build one because I don't trust myself with the safety. If I burn down the house with a uncertified makeshift solution no insurance will pay.
@@bitlunislab Put it in the garage.
@@bitlunislab You could contact Scott, he built one for his garage. And i got the feeling that Marco is doing the same soon. :D
@@bitlunislab Purchased and insurable or DIY and not, always a good idea to not have have house fire. Place away from house with fire suppression/safety system too. imo
Thanks for the reviews and info, it helps us all.
@@bitlunislab aren't LiFePO4 batteries extremely safe? I though that was the point of LiFePO4, lower energy density, but doesn't burn your house down.
this is a great little plan - shame the grid costs so much in the first place. where I live electricity costs between 7.4c/kWh-15.1c/kWh+fixed charges (5-10.7 euro cents as of today). I'd recommend some rails for your panels ideally so they don't blow away in the wind.
Where do you live?
My budget for mounting the panels is exhausted😂
@@kitecattestecke2303 ontario, canada
At that price point you'd actually make a loss if you tried to store it in a battery.
4:38 "not be very loud"...... ich empfehle einen Besuch beim Hörgeräteakustiker. Das ist die lauteste Powerstation, die ich bisher im Einsatz hatte. Und die Lüfter arbeiten scheinbar immer bei voller Drehzahl, wenn aktiviert. Da spielt die Leistungsabnahme nach meiner bisherigen Erfahrung keine Rolle. Selbst bei 40 Watt Last, ist das eine enromer Lärm.
Thanks for this video! I did not hear about this provider before, very interesting, was always trying to get a cheaper deal in Germany on check24 but my last find turned out to be a massive crook! So I will look into that new option :)
hi bitluni, I have a question please, I am working on an external cutter for my thermal printer ( i want to cut the labels after they are printed) so i need to extract the information containing the length of the label to assure a precise and clean cut of the label.
i successfully sent that information from the printer to my pc via the usb cable ( the information was sent in hex ) is there any way to send the same information to the microcontroller of the cutter ? when i cut the usb cable in 2 and tried to sniff out the signal with an analyser, the pc displays an error regarding the cable, when i remove the analyser things get back to normal
Hi, like your videos. Can you explain what you did try to reach in the video by connecting the inverter to the Oukitel? The inverters needs as input DC rite and output is AC. When you connect it to the Oukitel AC is being put in. Am i rite?
at 4:45, warm air coming out of on a cold day might actually be yousfull for keeping warm, well at least for 5 hours anyway? 🙂
in turkey, unlicensed electricity production from the sun is limited to 25kw.. (kinda) you can sell excess capacity to the grid but you can't oversell (or overload) to the grid. the voltage stays in the limit in a sunny day (~245volt) nowadays...
3:30 are you defragging an SSD?
Without iot the question is, how controlling the power input from the powerbank would work. I can imagine a couple of sketchy solutions, but is there a nice way to do this?
Wieviel Strom verbraucht das Gerät täglich, wenn es ständig am Netz angesteckt ist ( quasi als USV ) und kein Strom entnommen wird ?
can it be charged with solar and grid at the same time ?
You say the balkonkraftwerk is limited to 800w in Europe, but I have never heard of it being allowed to pump electricity back into the grid through power sockets, and while that's ok in Germany, i'm sure this is not a thing in many other countries. For example it isn't here in Ireland, as far as I'm aware, and tried to look into it before getting proper roof solar. Otherwise, great work as always on the videos, this is really good stuff :)
800W is somewhat a tolerated limit and you need to notify your local power "authority". You are not allowed to feed back past your meter into the main grid without a proper contract, as well.
I just hope the governments realize quickly that opening the grid to decentralized power production is the future.
@@bitlunislab hm, to be precise - the limit in germany for now is 600W - 800W is the EU regulation, which is also not yet implemented in all eu member states…
I wonder if it could power a whole home via a suicide cord.
Sure, but you have to disconnect from the grid, else the battery is empty pretty fast.
Why? Just use it in UPS mode.
Get it close to the important loads: fridge, etc and if the power goes down you wouldn't notice.
You legally need an ATS installed on your grid feed to do that, otherwise you'll risk killing line workers during a power cut.
No it wouldn't - it's single phase and not strong enough for the ofen...
@@gsuberland only if you want it to be automatic, manually pulling the main breakers should be fine, shoulnd it?
Maybe an option to exeed the 600W limit, also here in the Netherlands, a PV-distribution board? You can hookup a maximum of 12 panels with this configuration in the Netherlands. Only disadvantage is, you cant have any branches before the PV-distribution board.
yes a "pv-verdeler" is indeed a good solution in the Netherlands. But I think Germany has additional limitations on installation and contracts. What might be legal though is "overpanel" a small grid tie inverter that is limited to 800W on the AC side but can handle much more Wp on the DC side. This will result in a 800w AC for a big part of the day. (please check your German legality)
I have a big PV setup. I get 12ct for deliver to the grid. My electricity contract (100% renewable energy) is at about 40ct. if those numbers would be constant in future the power bank will pay off after about 14000 cycles... I guess this will not be reached, so it will never pay off 😞 (the costs of this system in the link is 3700€, do I get 8% and 400€ combined or how do you get the 3000€ from the viedo)
Needs iot integrations with remote ways to turn of input I want a house power supply , I have solar up to 3000w but power at night is so much and uk rules for selling power are silly and won't let me even with all the documents they asked for , storing and using it would be amazing when I can get home assistant to manage it
You may be able to replace the noisy fans with something better and larger. Noctuas perhaps?
shouldn't be too hard to mod
@@bitlunislab I tried it. The original fans have 6000 rpm and they are working almost all the time at full speed. I replaced the 2 fans that draw air in and cool the AC inverter of the power station. I used the Noctua NF-A8 FLX 80mm model. But the Noctua is too weak, it has only 2000rpm and the airflow was barely noticeable. In addition, the Noctua has rewired cables and a different connector than the power station, so a small modification to the fan connection cable was required.
I ended up putting the original fans back because I was worried that the Noctua wouldn't be able to cool the AC innverter with its poor performance and I could damage the power station.
Power stations have very poor input-to-output efficiencies though, typically only around 65-70%. If you really want to load-shift, you need to do it with discrete, higher efficiency components and you need to keep the C-rate going into or out of the battery at 0.2C or lower.
For power stations, the input stage (charging) - typically 85%. Battery efficiency (at 0.2C) is around 95%, and the AC output stage is about 85%. 0.85 * 0.95 * 0.85 = 0.686. 68.6%, typically. Worse if charging too quickly or running heavy loads.
For a discrete solution, a modern MPPT charge controller is 98% efficient, the battery (at 0.2C, 48V/51.2V LiFePO4) is 95% efficient, and a real micro-inverter like an Enphase (for example, wired into a 240VAC circuit) is 98%. The cheap retail 120VAC microinverters are typically only 80% to 85% efficient (even the ones advertising 90%+ efficiency are usually terrible). You can tell because they get hot or require fans.... a big red flag that the thing isn't efficient.
In anycase, for a discrete solution with good components, the input-to-output efficiency is 0.98 * 0.95 * 0.98 = 91.2%.
Good components would be, for example, Victron charge controllers, 48V/51.2V LiFePO4 batteries (almost any brand), and Enphase or similar micro-inverters wired to 240VAC. Stay grid-tied and just push power during the period that you want to load-shift out of.
Also, depending on the micro-inverter, you might need another charge controller or current-limited buck converter on the output side in-between the battery and the micro-inverter to control the power. That opens another can of worms.
--
A second way of doing load-shifting is to run the solar directly into the discrete solution plus an inverter and run your equipment from that, essentially off-grid but not quite. Then have a programmable battery charger provide load-support to the system from the grid rather than trying to use automatic transfer switches or a UPS to switch the loads when the battery gets low.
This solution works well when the amount of load support required is minimal. i.e. when there is enough solar to run the equipment 24x7 on reasonably sunny days so the load support only kicks in when it's been cloudy too long or during a storm or something like that. Efficiency is higher under these circumstances because during the day the solar more or less runs the inverter directly so the battery round-trip only counts at night.
The load-support is also "ok", since it is also supplying the inverter directly, but the load-support has two conversions (AC charger and the system inverter), so it isn't as efficient as one might like. But it IS a great solution if there is usually enough solar to bridge 24 hours.

Seems like a solid unit besides the inverter size. 2200 watts is a joke for a 5+ KW power station.
The paper I linked shows that lifetime halfs when going above 2C and 25°C. So be sure you got some serious cooling when going 8kW
@bitluni The hell are you talking about? Lol 8kw?
In UPS mode, does the unit have a beeper or some way to warn you if the battery level is low?
I didn't notice anything the two times I drained it completely
Tell us more how you found out about the battery protection!
one should not use a brass standoff to touch a positive 24v pin and the connector housing...
Now we know and learned :). Until next time.
we just need this tech to be acessible for every country, mainly the less affortunate ones
4:00 C-plug?!?! no thay are called Shuko. C-plugs are the small ones on the other side.
diy metal air with KOH or CuSO4 + dilute H2SO4 water electrolyte + graphite electrode as simple feed more battery (steel sheet spool feed)
dont leave the iron/steel in the electrolyte, only feed when its being used, like in a gasoline car, but its a iron-air fuel cell from a sheet spool
Combine that with a wind turbine (small) you will get much more power (free).
"Important tasks" = defrags the hard drive. Man I feel old...
I love when people notice.... too bad I forgot to put the iconic HDD sound there 😂
I use a propane generator as a hurricane ripped my house apart last year
Sounds interesting. I would be surprised if this power station could handle frequent use without its capacitors peeing themselves ... or exploding ...
Es ist sogar auf 600watt Limitiert im Deutschland nicht nur 800watt
12:42 - just roll the tape then, then we don't need to ask 😉😂 you got it on tape, yes? 🤔
unfortunately, I miss the sparky situations often. but the powerbank seems to have a good protection against dead shorts 😬
@@bitlunislab That is great the one cannot destroy the powerbank! 👌 Does it have RCCB/RCB function, as that would be nice, even if not providing protection against your fingers if you plug one in each hole. Then goodbye fingers as they will get cooked 😐 ..as a programmer I would like to keep all 10 digits 😉🤓
Generator 3,7k ;(

430€ electricity bill
Ouch
Zwykłe akumulatory kwasowe "ciężarówkowe" to tani magazyn energii z paneli. Off-grid. Projekt oczywiście stacjonarny ;-)
Just wanted to share my crazy fact.
2999 euro means 425516 nepalese rupees. My average electricity bill is 500 NPR per month. So with the money to buy that device, i can pay my electricity bill for 70.89 years.😂😂
Saving monthly energy costs trough an investment that will pay pack in time and provides free energy is not hoardy imo.
While free energy is nice, this is just a failure of the "smart" decisions made in Germany to combat a non-existent issues! Bravo!
Love it man, have you ever considered using flywheels for energy storage? I've heard some solar farms are using flywheels with magnetic bearings in a vacuum for energy storage, I'd love to see what you could do with your setup!
hmmm, that's actually a great idea. My spouse will hate me when I try to convince her. I mean the bigger the diameter the better
How can a 3500€ power station called to be cheap on a diy channel ?
My LFP cell battery out of EVE cells has cost me about 1500€ and a 3000 W inverter is less than 500€ incl. a woodmade case, so 2000€ in total is way cheaper than a 3500€ powerstation
Looks like the channel is moving as so many channels nowadays are selling crappy goods but remember that even you can be made reliable for damages caused by the products you had avertised as the crypto advertisors had paid already millions for their sbf crypto advertising. And you are facing the same issue especially from american viewers.
And then the cheap powerbank becomes a time bomb as the video is a time bomb
Where is the advertising sign ?
2 brands and 2 campaigns for tibber and the power station- you are in dangerous high waters if you ask a lawyer considering these promoted brands offered payment and free prodcuts cause affiliate links and marketing is #1 advertising and #2 taxable income.
A free delivery of a product will be taxed like income as all those tesla cars had been taxed as additional income in Germany back in the days when tesla rewarded the best tesla affiliate link sellers with free cars. And the that tax bill was a big bummer for them cause most of them could not believe that. Nowadays they get a lottery participation and if they win the car of such a quarter it is lottery win which is tax free like all other lottery wins.
So you have to obeye the german advertising policies, mark the video clearly as advertising for the whole time and you also got in trouble with the country legislation about the question if your channel can be seen as a tv show which would add a lot more requirements onto the channel like child protection questions and what not.
This very, very expensive power stations can become a big bummer for a lot of youtubers once they get behind all the implications. You called it a 3500€ powerstation - which means you will have to pay the taxes for at least 3500€ and on top church taxes.
this powerstation is a whole crap based on the price it costs and even now with tibber prices you can not make money out of that. If you can get the cheap tibber tarif prices you still have to pay the local fees for the power line system of round about 16 cent. Even on the cheapest days your price will be above 12 Cent and considering 20% losses charging the powerstation with tibber power means that you will have to pay 1,2 kWh to later benefit from 1 kWh out of the powerstation. So your 12 Cents are now 14,4 Cents and the average price for new contracts is about 35 cents, so 20 cent is the max you can make a day per kWh used out of the battery, but the usual cheap tibber tarifs I can watch here are only for a limited amount of time during noon while you will try to charge the battery with solar power, right ?
Then your powerstation charge controller is blocked and solar power is also cheaper. Anyway you can only use such battery for 3000 to 4000 cycles and the more they are moved around the lower the capacity duty to micro damages inside the battery cause these powerstations are build out cheap grade b cells that the chinese government has not allowed to be used in cars due to the vibrations there, so vibrations and lifting a battery causes risks and damages otherwise they would not be sold as grade b
If you can make 4000 cycles and can save 15 cent per kWh you might get 20.000 kWh out of the powerstation but I doubt the inverter cramped in such a tiny space will survive that long.
Any how: 20.000 kWh x 15 cent = 3.000€ max. profits if you can save 15 cent per kWh which is not impossible but will take quite a while or in particular about 10 years.
And it will force you to change your and your familys habits to run your home or consumers off grid from the powerstation, lots of cables if you really want to make a profit.
Finally you will hardly reach the 3500€ savings needed to let the powerstation pay off itself or you have to store a lot of energy from the balkonkraftwerk in the battery and even that is limited right now to maximum 600W inverter if connected to the grid so you might need an additional off grid solar panel array but even that would not be enough: You still have to be in the 600W limits legally unless you are going fully off grid which requires to have NO GRID CONNECTION ANYMORE. Then you can do what you want but only within the legal limits - that the city council will have to check. And there are local saftey requirements that describe how you have to protect the modules against the wind and snow and if you check those regulations carefully you will see high and heavy loads of over 40 kg per module - that is why the 50€ black ibu boxes for car garage roofs and so on come with a manual that describe how to calculate the local wind load and how much weight you have to put into the black containers to then mount 1 or 2 panels on top of it. These regulations are part of the liability of every house owner has to take and date back to the permission to build such house.
Thanks for your input. I disclosed any affiliation, but I turned on the YT thing now so people who watch it without audio and subs will see that, too.
This is a DIY channel, but I'm always aware of the dangers of battery solutions. No insurance will pay if the DIY battery will burn down your house unless you certify it.
you looks like a joker, not everyone is so smart than you, Not everyone have time to DIY battery by themself, and there is a safety problem while DIY battery without extensive experience.your comments are more like a fraudulent person coming to deliberately attack the person who chose the power station. Like eg, People who bought gas car deliberately attacked people who bought electric cars, anyone has the right to choose
You should also consider the price of the inverter and solar panels. If you take these factors into account, then you will need decades to recover the money you have spent on the setup. Instead we can keep the money as FD or invest in SIP or mutual funds. This setup makes sense for you as you have got the inverter for free(assuming).
It never ceases to amaze me how little Energy Europeans use. Out house uses between 80-120kwh a day during a Florida summer. Thats around 1.2Mwh and 1.4Mwh a month
That battery pack would last approximately 45minutes powering my home.
I assume your cost calculation would cover more than 5 years. In that case, it would be helpful to include depreciation cost of power bank and solar using straight line method. If Germany kept running their nuclear reactors, you wouldn't worry much about this experiment would you?
It's a highly political opinion. France and Germany should make a deal where Germany supports France in the Summer where the droughts cause nuclear plant to shut down and France supports Germany in Winter when the sun is low.
It happens with the market to some extent but working with an "GWh account" would be cheaper for everyone.
@@bitlunislab That would only work if France can keep their reactors working at all. Part of the reason why electricity was so expensive last winter was, that France was buying huge amounts of electricity, because many of their reactors were down because of unplanned repairs. They found cracks in many of the reactors. Repairing them is very difficult and time consuming. Also, they are still investigating some reactors, so there might be more unplanned maintenance.
That's a fair assumption, but an incorrect one. The standard regulation known as the "merit order principle" states that the most expensive power plant, which is still needed to meet demand, determines the price of electricity. This means that all other, less expensive suppliers can also charge this same high price. And so they did when gas suddenly got prohibitively expensive for a short while.
(Consumer) energy costs in Germany have been among the highest for as long as I can recall. It's definitely been like this even before the accident in Fukushima happened, that lead to the decision to shut down nuclear power plants in Germany.
Yet Germany is a net exporter of electricity still, as per Reuters: "[Germany] also is a net exporter of electricity and even expanded that role in 2022 despite an energy crisis at home."
130 Watt is ja nix 😂
First to comment on this youtube video!
You got paid for the video. The powerbank itself is worth about 3000 . So unless you sent it back or paid for it yourself, that is quite the big payment you received for the review.
Every time i hear a TH-camr say he didn't get paid while standing before thousands worth of equipment sent his or her way for free, i think how stupid do they think their viewers are.
Germany does not have a renewables surplus. Uniper was spending millions a day on fossil fuels during the winter.
Now do the calculations with proper LiFePo4 batteries from China that are at least two times cheaper instead of taking overpriced shitty products from local suplliers for a review. Aliexpress 7,6 kWh battery 1600€ with BMS and all connections.
Thanks.
