Who has experience with a so-called balcony power plant?
There are now many suppliers of these solar cells, which you connect via a plug, known as balcony power plants. This is now even regulated by law, and these devices are legal up to 600 watts. I'm just wondering: the installation in an apartment is generally three-phase. The inverter is connected to a Schuko socket, so it only feeds one phase. Now, it could happen that there are few or no consumers on this phase in my apartment. So, would such a device be of any use to me?

The counters are salivating counters.
That’s the key point I needed. Thank you.
Hello,
I answered a similar question today, which can also serve as an answer to your question.
Here to use my previous answer:
“I bought a solar – balcony power plant last year and can recommend it to you, it is Growatt, the website:https://de.growattpower.com/
I bought a portable power station and 3x200W solar panel, these solar panels are now charging my power station on the balcony. Since the Growatt Powerstation is not fixedly mounted, it can be transported well so that I can also take it with the camping because it can charge most of the daily electrical appliances. No problems have occurred so far, and I believe that quality is guaranteed.
The installation is actually convenient, who really cannot, can also ask the customer service. Total costs were less than EUR 3000.
But before the purchase you need to know:
Hope my answer helpful for you : )”
Look at the video.

I actually took the guy almost the whole video, with trouble. However, the information content is low. The only important word that has fallen is “saling current meters”. The rest is Gelaber.
Quite arrogant in a “valuation” of one thing, where one does not even know what one seeks conceptually (see your question of content).
Hut, I happen to know the channel and have seen some videos. It’s just like I find it hard to digest. And honestly, he didn’t say a lot about it. Instead of this, he can be used as a phase tester forever.
Yes!!!
I got my bill today.
I only consume half of what I used earlier. It’s worth it.
No matter which phase you feed or consume, the counter salutes it!
Hello,
If you expressly do not want to build an “island installation”, your main advantage is only the combination of energy return feed into the network, or direct removal from the integrated inverter for your own devices.
Balcony power plants are now available in different versions, but you can already test in your apartment which sockets are in which rooms on which phase of house installation if you get something “in-phase”.
And then you have to count on something more worthwhile for you: “feeding, or saving” in the balance of your daily presence.
But I assume that a saved KWh is likely to bring you more than a backward fed KWh.
I decided in a certain core of certain equipment for a pure island solution, to which I currently only lack a sine inverter for the e-scooter and my notebook. The rest goes from the controllers via USB and 12 / 24 Volt = directly to the devices.
In the case of an “island” with a rechargeable battery, it must be calculated differently in terms of back-feeding and saving in depreciation, because the batteries at the island have to be pre-financed for the first time, and there are also degrees of efficiency to be taken into account.

No, I’m not planning an island, not a battery. This seems to me unrefinable in view of the possible savings or yields. It would have been a certain security of supply, but in order for me to do this, I would have to think quite large.
I am not quite clear how such a three-phase counter reacts when, for example, current is taken from another phase at the phase at which the solar cell hangs. Does that work? What does he count?
In the end, only the electricity that I consume myself and therefore not have to pay from the provider brings me financially.
Here, too, you have to expect efficiency, because a “balcony power plant” works with two panels in the rated range iwo only with ~ 12 to 48 volt DC voltage for input into the inverter.
The whole network feed is synchronous monitoring from PV to grid also needs some energy, which makes me roughly from efficiency by about 70 to max. ~ 80 % would start from the network input panel.
But now you have averaged the weather and the daily sunshine of your panels. Where and how you will be able to build your panels with you?
600 WP sound good for the included panels, but in DE they only achieve this in an absolutely clear sky in vertical irradiation.
Partial shading of a large panel already lets the balance sheet break in massively.
This heaven too is already partly noticeable.
Well, I have an “island”, but balcony power plants also only occasionally bring approximately DAS, which is possible in the unchambered and as perpendicular as possible from above through the atmosphere.
My opinion… the Shield will not bring you anything if you don’t have your panels in the best way in your region on the sun.
Then even promised 600 WP suddenly become quite little in the year harvest.
Thanks for the comment. It’s not the same as the feeding.
