OK, seen. In any case, a ground installation is not eligible for the purchasing obligation so you are obliged to consume everything. Hence the batteries, hence the price of the kit.

I did some calculations regarding my consumption. With 3 kWp of PVs and 15 kVA of batteries, I think I will ensure around 5 months of summer, by switching off the inverter at night and on overcast days. Even with total self-construction it is not depreciable. I admit I have difficulty with this "grail"...

Re: Leroy Sommer based hydroelectric generator with direct current

I have some doubts about the lifespan of the machine... It was for the quick demo, some YouTubers make crates of it, show it the essentials. He didn't make the junction between the propeller sections, it's not the most difficult, there are other videos which show it in more detail...
