Choosing fresh led lighting equipment?

Question

Do it yourself

I want to organize smart lighting at home, and later transfer everything to solar panels.
There are two main questions:
First, did I understand the logic correctly:
from the sun we power the lighting of the
photo module (12V) -> Charge controller-> battery-> dimer-> tape (12V)
from the sun we power the devices
module (12V) -> Charge controller-> battery -> converter (from 12 to 220) -> consumer (220V)
if you don’t install panels yet, then you will need a converter from 220 to 12 for the tape.
Maybe there is an option to use converters less, because they spend a lot on heat which I would like to avoid. Maybe I missed something
The second question is the devices listed above themselves. I read a lot of articles on habré and forums on topics, but the information is scattered there and most of the articles are 1-3 years old and most likely there is cheaper and more reliable equipment. Share your experience on what to take, what not to.
Solar panel 100W
Charge controller ??A (is it worth taking for each panel / room or buy 1 for the whole house?)
Converter from 12 to 220 (similar to a room or is it better for a house?)
Converter from 220 to 12 ??W is advised everywhere take 1 per piece of tape to avoid fading
dimer (can I use any to control the tape, let's say led lamps can only be special)
well, actually the tapes themselvesmostly 1 color (but I won’t refuse RGB options), for the street (closed) too, if you know.
The question is getting too broad, but the more I read, the more difficult it is for me to make a choice =/
preferably links to ebay, dx, amazon, etc
thanks in advance

Answer 1

And not a few 100 watts will be a solar panel?
One charge controller for the whole house, MPPT is better.
A 12V to 220V inverter can similarly be one per house, but it’s better to dance from the load.
If a refrigerator is planned, etc. , then take a pure sine and with a margin of power.
It also depends on whether full autonomy is assumed or there is access to the mains.
I recommend reading here:
www.forumhouse.ru/forums/162
I put solar panels 2 x 100 watt mono
www.solar-tronics.de/solarmodule/solarmodule-5-wat...
And two panels of my own production.
The entire assembly of 24 volt solar panels is connected through the controller to two 140Ah batteries in series. I also took a 24V inverter in Germany,
www.solar-tronics.de/spannungswandler-24v/wandler-...
but I decided to try welding from it and successfully burned it when trying to cook with 2mm electrodes. In September, I sent it by mail to Russia for warranty repairs, but it still has not arrived in Germany ...
In December-January, the charge almost does not go, because. solar panels are sprinkled with snow (respectively, it is necessary to clean) and a short daylight hours.
I took LED lamps for 12 volts on aliexpress, at discount prices the price is much more humane than in stores (4 times).
If significant power is planned, it is worth looking at 24V or 48V, because. there is less current at the same power and, accordingly, losses are also less.

Answer 2

I took 100 watts as a unit of calculation, everywhere on the forums they write that it is better to take three for a hundred, the price is the same, but it is more convenient to install and transport. Soldering myself, although cheaper, but I won’t undertake it, I’m afraid to spoil it in soldering is rather weak.
Automatic full immediately very expensive. I found such a thing that regulates consumption depending on the production of panels, and draws a shortage from the city, it costs about 10,000 rubles, but I don’t know if they will give it a head of the power grid if they come to check. So far, I have ordered such a thing www.aliexpress.com/snapshot/301517704.html "counter" for one reconnaissance. I will count consumers and figure out how much it takes for each room and connect in turn.
Thanks for the answer, especially for the comment that you should not do solar welding, my father is a welder, he could have thought of it later =)
