Just a little disclaimer for anyone wondering, this is an early prototype to test the feasibility of the chosen topology. !!! UNDER NO CIRCUMSTANCE should you use this as it is to DELIVER POWER into the grid !!! !!! It is an NON-ISOLATED topology, meaning that the entire inverter as well as the connected solar panels are LIVE at all times !!! !!! Without special precautions that efectively isolate your grid and eliminate any risk of energy flowing outside, operating this inverter is HIGLY ILLEGAL in most countries and can be easily DETECTED by the power company if you have a modern digital power meter (analog ones will just spin backwards) !!! I uploaded it to share ideas and hopefully get some useful feedback from anyone in the comments. Thank you for your understanding!

That's some impressive sequence/chain of development! Good work!

Hezký analogový řízení, jinak na ty hliníkový desky doporučuju předehřev na plotýnce, jinak se to velmi špatně pájí protože fakt dobře odvádí teplo. Bylo to jako učit se znova pájet, když jsem s tím pracoval :) Možná nevýhoda je velká kapacita spojů proti hliníku, na silovku je to dobrý, ale kdyby tam bylo i řízení, tak je třeba ten hliník spojit s gnd, aby se to nepřenášelo zpátky do vstupů.

Díky za tipy, nejspíš to celý budu pájet plotýnkou s trochou horkovzduchu na připájení cívky. Kapacitu rozhodně prozkoumám, ona by se takhle i hodila jako blokování navíc.
