Cheap grid tie solar setup (600W 3kWh/day)
Вставка
- Опубліковано 30 вер 2024
- I needed an upgrade for my solar setup since the utility bills got outrageous. The cheap grid tie inverter is easy to setup and saves me 1€/day now. I tested the microinverter and it's working fine making 3kWh/day with two 300W panels. The highest output I measured with my clamp meter at was 2A AC which corresponds to about 520Watts. That's nice because I didn't spend a penny for the mount. The app allows to control the output so you can limit it if you need.
New merch is here! merch.bitluni....
In Germany the inverter can't exceed 600W so be cautious: www.vde.com/de...

Hey! where did you get the panels from?
your link shows flexible ones from Ali but that doesn't seem to be the ones you are using
Unfortunately the panels are long gone. Basically any link I would put there would expire fast currently. That flex panel link is just a proven source, since a friend bought these. It's more suitable for balcony installations. You can get hard framed panels for 150€/350W atm with some waiting time. Don't feed the scalpers
@@bitluni The flex panel is 12V, but the microinverter says its input should be 22-60V. Would I need two panels in series to make it work?
And now hope that you don't get a Beaufort 11 storm any time soon! If I would just lay them down like that on my roof, they would not last a week.
Just fix them with some garden stones as weight that's how the solar panels are normally fixed on a flat roof.
@@Tom-ku8bu or by mounting them with sedum mounts, eco friendly too
The single panel like shown in the beginning lasted several storms in the past 3 years without moving anywhere. Last storm was Zeynep with speeds around 150km/h. Those panels are quite heavy. The wind always comes from the front of the garage since it's the luv of the hill I'm living on. There is no gap for the air to go underneath the panel this way. I guess it doesn't cost much effort to just screw it to some slat and put some extra sand sacks to hold it better in place. I'm too lazy though 😂
Nice work Bitluni.....I wonder, aren't you worried about losing the entire solar panels etc next time a big wind storm comes through?
That will be more content. 😂
Where I live the wind would help you get them down for cleaning, usually the same day.
This is a real concern, especially since bad weather is becoming more common in germany. We had quite a few "storms" recently.
sorry to say that maybe you are from Netherlands or UK but this is nothing to worry about in most part of Germany.
The cheap micro inverters often have insufficient filtering resulting in many spurious harmonics and failing to comply with EMC regulations. They are by far the most problematic consumer RF noise source now a days.
True. I had to switch the inverters off while testing the $16 HF SDR thing.
And are those inverters save and comply to European safety rules (like switching off during grid maintenance or high voltage)?
@@peli71 exactly!
My trust of products made of Chinesium doesn't extend to mains voltages!
Great stuff. I did something similar but you need to consider WIND. At some point you will have strong winds from the wrong direction. I used stainless steel wire to strap the panels to a fix point. Before this, wind moved all my panels but I was lucky. No damage but only due to luck.
Having the mains on the roof is still safer than having high voltage DC (many panels in series), which easily can start fires if not wired properly or exposed to moisture and therefore producing arcs. As long as your protective earth is working (testing the breaker) everything will be alright when a fault does occur
I appreciate your safety footwear... 😏
Now in NL: 3200 watt allowed on a seperate group, or wasmachine group with a" pv divider, breaker" added.
widowmaker cable? presumably the inverter is grid-tied so should shutdown if unplugged, but ...
wusste garnicht das du aus der gegend von darmstadt kommst :-D
Due to the increase in energy prices, I do not use the lighting in the toilet ... But I have to wash the floor more often ...
Du kannst übrigens mehr Module anschließen, solange der Wechselrichter nicht mehr als 600W durchlässt.
Use a battery to store excess energy. I saw 2x600w plug and play Panels for just €300,- 2day 🤑
Can i plug two more inverters on diffrent phases and have 3 phase inverter? Will it work? Do i need to connect inverters togeather with data cable to have nice sine on 3 phase or not?
iv had one 250watt panel on my garage roof here in UK for 8years with a Replus micro inverter been great no problems, i refused a smart meter i told them the meter ant that smart as it will charge me for power, for pushing power back to them . i have also put an aluminium cross piece on penal and weighted it no storm has mover it an inch yet. as far as getting to trouble as long as you don't have an analogue meter spinning backwards then no problem ,if you are doing DIY a few panels only is the way to go ,as it grid tie say 400 or 500 watts then thats best way to go you will be using most of that output. A word on cheap Chinese invers they don't last long ,Enphase is the best you'll probably get a life time out of them, i got 6 months form cheap Chinese one , i'm on 8th year Renesola Replus micro inverter but i can't find them anymore as i have jest got another 235watt panel, Enphase are expensive ,may have to bite the bullet .
Question, are you not worried that the Alibaba supplied mobile phone app is riddled with spyware and the like. From what i have read there is always a pretty significant chance that china created hardware that relies on centralized server for proxying of data can have spyware, data collection, etc, and you will never know. I believe there was a scandal recently of MANY baby monitors that were Chinese made and that people's information and private videos were being farmed.
I buy a lot of Chinese made electronics, but am very leery of any non-established brand product out there that is asking me to connect my phone to their servers.
Thoughts on this?
Easy install and well explained. You could increase your harvested energy if you tilt the panels a bit more. Especially in winter.
With panels just sitting on the roof I would be worried about high winds picking them up and blowing them away/breaking them.
We had really hefty storms this year already and it didn't move. I put the one the wooden blocks later. These things are heavy
Nice. We're not allowed to do it ourselves in the UK. Well I mean if you wanted to do it legally then you would need an "MCS" approved installer to do it. I have two solar arrays and I wish I had space for more, so I recently put one on my shed roof and used an MPPT charger to charge two LiFePO4 batteries and then I run everything in my shed workshop from that.
It seems like we're in a similar situation on the other side of the channel. The government provides many nice things like tax breaks on solar panels (10% instead of 20) and financial aids but of course there's a problem: the whole installation has to be done by a pro which negates all of these nice advantages.
I believe you actually can do this youself without MCS approved but your not allowed to get any FIT/SEQ (paid from the energy exported or generated). Also you are limited on what size you can connect to the grid. You do need to let your DNO know however but shouldnt be an issue for small installations that are compliant with safety standards
I've seen nothing that suggests that this is not accepted in UK. The installers with MCS approvals might want you to think otherwise, of course. But then they are limited to 5kW systems whereas those that do not feed back into the national electrical grid can be any size that suits the project.
nice video, I've done the same for the last 2 years, 600 watts at 24volts and 100watts at 12volts into battery storage and then into grid tie, pay only for 1Kw or their abouts a day (40P). It's the way to go, switch my gas boiler off too so pay nothing for that either
Very cool!
Hey, but when you use the battery, doesn't the inverter just send energy to the grid? Or is there someway to deal with that??
it's cheaper to just plug in like in the video using grid-tie micro-inverter, no need for battery or charge controller.
@@leps75 if you connect grid-tie-inverter in parallel with charge-controller then the battery will not feed into the grid (method 1). Alternatively, if you connect grid-tie-inverter to the battery you can automatically connect/disconnect the grid-tie-inverter using a Relay with an on/off signal coming off from the Load terminal on the charge-controller (method 2). Alternatively, there's a larger pricier charge-controller that combine all 3 device into 1 (method 3) .
@@xponen that is true, but solar works during the day, when most people are out. It's when the sun comes down and we all get sucked into are electrical life and there is no solar...
A battery allows you to shave that peak rate.
* Most people are getting suckered with lfp fake battery info and high prices.
So yes. They could use la for 100 times less.
@bitluni to the rescue there ??
Yeah, lets limit the energy people can put back into the grid during an energy crisis.... thats logical.... governments need to stop trying to protect the profits of the power generation/supply companies and allow people to be more self sufficient and actually offer more efficient energy generation.
Sure, until someone has their jerry-rigged 4kW system go haywire and fry all their neighbors inverters at the same time.
Having standards and regulations for the national grid is kind of important.
@@hultaelit I didn't say that there shouldn't be a standard, I said it shouldn't be limited to 600W ! other countries can export several kW to the grid if they choose.
It depends on the grid. If the grid voltage is already high then you won't be able to put any power back into the grid. It's not just about protecting profits, there's serious practical limitations too.
Those 600W things are a legal way to attach your DIY solar to the grid. Some legislations do not specify if the 600W are per phase or not. Makes 1.8kw. Inspectionless, no permits, no fees. I get paid only 8ct kwh for feeding the net, but i save 24ct kwh on my own consumption. Germans save up to 40ct/kwh. If you run an AC this is the way to go.
Those limitations won't last long as the crisis will peak next winter. However there are possibilities to limit your output to the grid to basically 0 with specific inverters. I'd like to try that once I have some spare funds
Please correct de title and use the appropriate units :D
Cheap grid tie solar setup (600W 3kWh/day)
Unfortunately setups like that are illegal here. I can however use a transfer switch and run individual circuits off solar.
You can build something like this, hidden, no legal (who cares), but posting it on youtube with full adress? Good way to gain interest of the network provider and other authorities. BTW: The rest of the wiring in the shed is also terrible :-) The trouble starts if somethings goes wrong, eg. a fire starts. The insurance may no pay. This is the danger of "non official" installations. 🙂
@@hesspet Many of the North American meters in their default configuration will charge power exported the same as if you were drawing from the grid.
@@eDoc2020 Not true. Disinfo from the energy provider. The old style elecromechanical meters will run backwards.
@@pepethefrog7193 I don't think I've seen an old-school meter in use for over a decade. I'm specifically referring to the Itron meters which have been in my area for close to twenty years. I'm getting my information from the technical manual for the meter as presented in its FCC filing.
😳
Du könntest ein bisschen was gegen die HF störungen machen die die teile abgeben ... damit habe ich nämlich extreme probleme ... ein einfacher Netzfilter hat es leider nicht beseitigt, wäre bestimmt ein Video wert
Your workshop look like it's built as a bunker!
The one foot of poured reinforced concrete roof gave it away :)
If it only was just as waterproof .. it's dripping all the time inside... but it's a rental so I don't spend a penny on fixing that
@@bitluni Flat roof and no asphalt cover to stop the water, does that :)
Hi, I have the same electric car. Waiting patiently for your solar charging video :-)
Hi. I live in Germany. What steps did you took to become a smart meter and what was the cost? I'm thinking to do the same... Thanks
Collect as much as possible energy (resources) yourself instead of being dependent to become a smart meter in Germany.
Dude, you’re funny as hell! Which part of Germany are you at?
From the video and the description it looks like you know the difference between kW and kWh well. Please keep it right in the title as well.
I couldn’t quite work out if you were planning to mount the unit flat under the panels and trust that the seals hold ? In the past mounting vertically and leaving a small moisture exit point at the bottom edge has worked for my outdoor projects. Sometimes a small piece of gauze helps stop bug visitors. Good luck!
yea, every night the device will be cold and suck in outside air, after many years the accumulated condensate will have no way to get out.
Hello mate,
Excellent video!!
One question, is it possible to give the direct link to the 700w microinverter that you bought in Ali, please? Because the first link that you have in the description it’s no going directly to the microinverter!
Thanks
Hi, are the inverters still working? I'm reading/hearing /seeing very mixed experiences with these invereters.
Please fix the wrong unit in the title (kW/day) ☹️
Nach dem VDE Link von dir ist man erst mal bedient! Typisch deutsch 1000 Auflagen damit alles schön umständlich und teuer wird. Bist du Elektriker, laut dem VDE gedönns wird das verlangt. Dabei kann das doch jeder halbwegs begabte. Hast du den 2 Wege Stromzähler? Wenn ja ist der normal schon vorhanden oder hast du einen neuen benötigt? Wurde eine spezielle Steckdose zum Einspeisen verwendet, wenn ja wie hoch ist die abgesichert mit wie viel Ampere? Diese ganze Zertifikate welche laut VDE benötigt werden, haben die Teile von AliExpress doch nicht.
how many panels would you need to recharge an EV car forever? is it feasible?
the only problem is the EV car companies can brick your car remotely at any time
a youtuber in Australia,Sydney said he need 8kw solar panel.
I put 2 250w panels on my shed roof a few years ago, and it has already made over 1.6MW of power in that time. Not bad for £100 of panels and a £70 inverter :).
I brought the DC down from the roof into the shed, where it goes into a DC circuit breaker, that way I can connect whatever I want to it without climbing onto the roof which was never really designed to have people standing on it.
Hi I am living in Germany as well.
may I ask if I want to have more power, can I take few sets of 800w system without any trouble?
I have many wall power plug sockets in the house😂😂😂
Don't use silicon in conjunction with rubber seals...
Neutral silicone should be fine, sanitary silicone is no no, it will make the rubber brittle.
bought one WVC600 LIFE it is connected to a 350w 60-120cell panel and the blue light keeps flashing.. I don’t know what to do. advice please.
I also never connected to any internet.. is this necessary?
Id wish i could only use 2 panels, 3 Computers 24x7 x750wh are the main consumers and that @ 35c
luckily we have 30 panels giving 80KHW at sunny summertime days.. good for 11000 KHw per year. ROI two-three years currently
awesome. My ROI estimate seems to be plausible then :-)
You should definitely make the panels resistant to wind / storm. If you are unlucky, on strong gust is enough to blow them away.
400 euros? Wow! .. I thought I was paying too much for electricity in my country.. Last month I paid the equivalent of 50 euros for 350kwh
i wish the us had such allowances for adding small panels with smart inverters. saw a video in california how a homeowner had to pay 20k for a contractor to install a ghetto 3kwh system with no storage on shelby churches channel. maybe $1800 worth of solar but she had to pay 20k for licensed install and permitting. really destroys the pay back period. i recently installed 200wat of flexible panels on my ev since there is no permitting needed and EV electricity is one of the most expensive. very simple setup wired into the 12v system but still offsets the consumption of the highvoltage battery. surprised no one else has really done this oneline. 11-18mo payback period. couldnt get such returns investing
I am curious if there are systems that come with an inverter each? e.g. so I could buy one or two panels + inverter and later upgrade with another 1/2 panels + inverter? I like the idea of having more modular setup's that can be improved over the years rather than paying for a large system all at once (and risking that they all fail at once if something goes wrong)
Crazy that the solar panels are just sitting on the roof. I guess you don’t worry about strong winds from hurricanes where you live.
these things weight a ton. They only look so light because I'm so strong 😂. We have winds over 100km/h here regularly nothing happened so far. If it does someday it will be content :-D
Bro energy costs are so high where you live....here in Florida its about 14 cents per kWh
Hi sir euro1 a day , that means your ROI
Is approximately 1 year
Is that true sir
That's amazing if true
Please clarify,
Thanks
Its interesting how your country arbitrarily limits how much power you can produce, while not outright preventing it completely. Energy dependance, slave to the energy overlords ;O Does your Micro inverter prevent Islanding?
The gasket doesn't cover everything - this is what you get when you buy from China. Imagine - the people who designed this hate their job and live a miserable life.
Im not sure what's the average temperature you have during the summer, but if it is pretty hot, you might want to add some extra gap between the panel and the roof to get a few more Watts.
Hi!
I have a question so if i plug in straight to the socket what is fused by livingroom sockets...i only will get power from inverter on that fuse circuit or the whole house ?
Something to note here is that the regulations don't apply if are completely off grid. But since the regulations are still kinda dumb the entire building is not allowed to have a grid connection. Just proper separation is not enough.
Beware of solar panels at low angles. The water pools on the corners, and if some water finds its way between the the insulation layers, the PV cells corrode. Bye bye solar panel.
you dont need micro inverter on free standing house stupid only 600 watt german ore EU law
going set up 5 kw solar panels that do dont need pay from grid why stay thailand
honestly ac wiring in water is safer than high amperage dc. also heat is the biggest factor in compromising working lifetime. keep it cool.
JESUDOM ist keiner seriöser Verkäufer. Nichts vom diesem Verkäufer kaufen.
JESUDOM is not a reputable seller. Don't buy anything from this seller
Can't u use the a
AC output of the micro inverter and connect it to a 4gang extension lead so I get AC power without conecting to the grid and batteries please let me know as I need to do testing outdoors
Not bad. Prices have gone up for this hardware and they're problems known .. where the micro invert melts.
They are at scalper prices as the 1200watt was £89. I thinks it's £289 now??
But they break fairly quickly.
(There is a website by model number for the problems)
These plug and play.... Ish systems I was going to do as my solar low budget. But they are too dangerous/risky.
The mounting not good.. if you have mastic base.then the solid packing foam (like neoprene) and then fix it down to the joist.
The law here allows on 20cm angle from a roof. Which is sad as 20 degress is the summer, but 20 off vertical in winter can make 50% difference. I guess the dictators don't want people taking or saving money.
Keep the updates going.
And I think 300w panels are the limit to the device some one has said.
Also du sprichst als Muttersprache deutsch… also kann ich endlich Kommentare auf deutsch schreiben.
ach was... wo hab ich das verraten :-D
@@bitluni nun ja, das Interface war immer auf deutsch.
Cant u just ise the AC output from the inverter and connect it to a power strip and use the ac power without using batteries or conecting to the grid?
hi, what is the app you are using? the app i have with my inverter is rubbish ! want to see if you app will work with my unit
Check the heat! My 300W inverters go into thermal throttling when mounted this way.
I think everyone having solar even on rental balconies is the future. These regulations will be adjusted for sure
This is a such hillarious nonsense in compare to a dirt-cheap nuclear energy.
Great video... makes me hungry again ;-)
Is the AliExpress Solar Panel a panel that is not a waste of money?
Did you really bought the 700W one with App support which ist illegal If you connect IT to the grid ?
Lots of troubles ahead considering that the local Power provider would force you to remove it at all due to exceeding the 600W AC limit.
It is not about 600V DC it is about the Impact on your grid in your house.
That is hard coded and no chance for discussion
Therefore your Video could be demonetized.violating local Rules and in a hazardrous Environment.
I'm also not sure If this one also had the issues of a bad pure sine wave which the channel Volt ampeere lux had investigated last year
how is the microinverter? still running? thanks
Nice aliexpress delivery reconstruction 😂
You can sell your solar power with your own installation in Germany? Here in France you need to pay for a “professional” installation to get the right to sell your produced energy. Thanks lobbies
I think that's what he eluded to around the 600W limit and needing professional install for more. Grid tie systems in most countries require pro install too like in UK and plug-in inverters are not legal at all here / fixing a plug on the end of the wire from the inverter also not legal. Power companies will make you sign a contract if you're going to get paid for it (or net metering, whichever) and they'll want to see install certs. This was the same at my friends house in NL too.
@@silverismoneyIt's ridiculous. Just install whatever You want, who the fock cares? Do You have inspections or what?
@@nitrgnlab9400 I get paid for my generation so I had to show them proof of qualified installation and testing. Of course anyone can do what he does in the video themselves too. Someone comes to read the meter every 2 years but no inspections as such no.
It is possible to sell the power, but not worth. The
In France there are commercial systems to do this. They market on the basis of being plug and play, no installation required.
I just finished to installed two 420 W panels on the wall of my house. I've bought all separately like you because of the high prices of kits. I had a APSystem micro inverter that seems to work only in certains security condition. For now I'm just at the step of connecting all things together and see if all is properly working!
In France you have to declare to the network manager company that you are going to install a micro inverter and be able to send in the public network the excess of electricity produced and so you have to give them a proper certificate for the micro inverter. It's why I didn't bought the one you get because no certificate was available in French... they only accept them in French!
So I hope this will work properly as I thought! Thanks for sharing your experience.
Does this work if you already have solar edge PV system installed (i mean the one with DC strings). I wonder if I add additonal micro inverter to my grid, can it damage my main PV when there will be surplus from micro inverter?
I bougth the same model, but the 3-pol AC connector only offers soldering the cable to it. Did you get the connector separately or do you have link?
3kWh/day please.. not kW. Sorry this is being confused often and adds to confusion for newcomers.
I read several times that those WVC micro inverters are known for not giving the full power output, although it could be panel compatibility issues.
As a continuity review: are you seeing 600w continuous output in the central hours of a sunny day? Danke
Is it not dangerous plugging it into a socket. Presumably that socket is one which if you plugged something in, it would power it? So you are putting power in, via something that gives power out?
Can you please add a command to clean display in your esp32 VGA out library. As it will be very useful for displaying moving data on screen.
Not scared that the wind takes your panels?
Get a small hybrid inverter from China, May be later you can add small battery bank. There are some models which has an export limit function
I also just got one of these WVC inverters with wifi, which can be controlled with the "cloud intelligence" app. Can''t find anyone having reversed the API to integrate it with homeassistant. Do you by chance plan on writing your own firmware for the inverter? I chose this model for having the option to throttle the output, as I have it connected to a battery instead of directly to solar.
what happens if the power from the network goes out? dont you need some kind of isolation switch?
Most of the microinverters need the grid power to generate, in the moment the grid get disconected they stop generating.
They don't work without the 50/60Hz from the grid. There are however hybrid inverters that you put between grid and your installation that will switch automatically
Man building some off grid batteries are probably worth it at $.50 a kwh with those other limitations and just run some loads off that system and if power goes out you still have power
you guys are using our KAIDENG brand inverters👍👍👍
I'm just curious, if you plug the inverter AC output into the wall circuit, would it affect the incoming AC coming from the grid? Short-circuit? Or does it somehow regulates itself?
you use 225kw per month??? jesus
Are you not afraid one hard wind blow makes these panels go up flying?
3 kWh / day *
Hi, thinking ahead…… have you managed to work out how to get this micro inverter working if there is no voltage present on the main supply…… in the event of a power outage?
How can you tell how much of the 3kW a day your producing is getting consumed by you or getting sent back to the grid?

Nice little setup, don't forget to bolt the panels down somehow, or they could go flying in a storm!
I've just got myself another 6 panels and all the mounting gubbins to install on my house roof... Just trying to talk my brother into assisting!
BTW, I don't know about your panels, but on mine it said that they're warranty is void if they don't have at least a 10 degree slope on them (I assume for drainage).
Given your location, ideally you would want more anyway.
Sehr nice. Ich will mir auch 600W bis 1kW aufs Garagendach legen für eine 600Wp "Balkonkraftwerk". Ich bin auf dein Video bzgl. laden vom eAuto gespannt. Mein ICCB zieht min. 600W. Ich glaube nicht das ich das mit den Panels bzw. dem Inverter abdecken kann. Aber da es die selbe Phase ist (Garage), kann ich dadurch vielleicht im Sommer 75% durch die Panels abdecken und den rest aus dem Netz halt beziehen.
Ich habe den gleichen in der 1200W Version der bei 600W schon sehr heiß wird. Deiner wird nicht alt werden, die Kondensatoren werden zu heiß.
Deshalb montiere ich die Inverter IMMER in der Garage, dort ist es kühler. Zudem ist der Wechselrichter NICHT wasserdicht, auch wenn das drauf steht, wirst schon sehen.

Great video, we need this 600W rule as well here in Bulgaria. Are You not worried of strong winds blowing your panels and possibly hurting someone?
Does the micro inverter feature an "NA-Schutz"? Isn't it required to have some sort of protection either by a special plug or some sort of protection mechanism?
What is energy crisis? 🇷🇺
And I like cheap 😄 Me too🙈
Your neighbors are waiting for the next storm, then the gods brings them free solar-panels💯
Great demo on how to do it but how do you keep your grid tie secure? I have looked in to this plug and play, and some "experts" mentioned that this will lead to having electricity in the grid even in case of electric shock or short circuit. Is this true and is there a way to get around this?
Its also a good idea to get more pannel power with only a 600w inverter to be under the limit and get more during the mornig and evening.
With these aliexpress inverters i also got issues with the powerline ethernet i guess they got bad emf
How would these compare to the enphase micro inverters? One single enphase micro inverter is in the same price range, however Enphase micro inverters are meant for 1 panel i think, these can handle 2 of them.
