Cheap grid tie solar setup (600W 3kWh/day) 

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?

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 😂

If I had more funds to my avail I would test some of the new hybrid inverters as well. Solar seems the best investment atm.

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.

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 :)

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!

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.

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.

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 ??

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

I think everyone having solar even on rental balconies is the future. These regulations will be adjusted for sure

RIP ping pong wall.

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

now I got panels producing ~400W and the similar WVC600: despite free airflow, shadow and 28°C ambient it overheats at 275W output power already. Crap! What do you get out of it during full sunlight? Mine averages on just 200W!

Use a battery to store excess energy. I saw 2x600w plug and play Panels for just €300,- 2day 🤑

awesome. My ROI estimate seems to be plausible then :-)

nothing happens. the inverter only produces power when it gets a feedback from the mains. it's a security feature and must have in Germany. otherwise you could switch the main breakers off because you want to change a light bulb. but if the inverter wouldn't care about it it would send 230v into the system and you could get electrocuted. so this is not a blackout fallback.

@@gnashermedia Thanks for the reply. I appreciate it. So this is not a backup solution, only a money saving option as long as the mains grid provides electricity. I conclude that having PV as backup it requires a hybrid inverter and batteries.

@@nikolaskallianiotis8622 Happy if I can help. I'm not a PV specialist. So take my 5 cent with a grain of salt. ;). To have a backup system using PV you need a mains integrated system. There are quite a few of there. The idea is that you have solar panels that charge a battery system and also provide power trough this battery system. To be exact the panels feed an inverter. This one charges the battery and provides the mains power support. Then you need a system that checks the mains power. If power is there you charge the battery and feed the rest into your mains and everything that is not used goes into the mains network. If mains power fails, than this system that monitors the mains tells the inverter to use the solar and battery power and it also drops the connection of your house for example from the mains. At this moment you are on a so called Island mode. You are a small island with your own power as long as the battery has power or the sun shines. If the system detects that the mains power is back it switches the mains back into your house and your back to solar supported usage. There are many systems that have this integrated. You need a system that monitors everything and manages the power handling. Those mini PV systems as in this video are only a support to save money and make your own environment friendly power. With a rating of 300 to 600W your can cover most of the standby usage of your devices for example. Instead of a big system you can use a power station or UPS to secure a few devices like computer or fridge etc. against a power loss. In case of a blackout you can also build a micro island. A power station like a EcoFlow River or Delta has Mains and PV input and supports something between 1000 and 2000 Watt output. So if you have something that shall be protected you can plug it into the power station and the power station into the mains. In case of power loss the station takes over as long as the battery lasts. If the blackout takes longer you can use solar panels to recharge the station over the day. That's what I have to secure some essential and vital systems I need. The power station lasts in my case 12 to 20 hours and I have 2x 100Wp panels to charge the station.

@@gnashermedia Great info indeed!!! That's what I need in fact. A backup system for power outages. Now here in Europe and especially in my case, Greece we expect during the summer lots of power outages because for (stupid) reasons not to mention here, we have based our main power generation on Wind Turbines and secondly on PV therefore our coal/gas and hydro generation is now the minority. So my urgent need is to support critical loads with some PV/backup system which won't cost an arm and a leg. Thanks again for your help!

Collect as much as possible energy (resources) yourself instead of being dependent to become a smart meter in Germany.

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.

😳

yes but an open hole will let it breathe

Bit late but.This are on grid inverter.They Need to read Power coming from the house or the will not turn on.what you Say Is what happen with off grid inverter

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

Neutral silicone should be fine, sanitary silicone is no no, it will make the rubber brittle.

a stopgap solution is to prepare a spare portable-inverter, then if power is out you turn off main-switch at distribution box then connect this portable-inverter to household plug. However there's no way to tell if the grid is back up with the main-switch switched-off, so this solution is a stopgap/emergency solution and you must manually set up these stuff each time you want to use it or remove it back again to check for grid power.
