I'm not complaining, I'm just stating it as a fact.
I mentioned Factorio; I probably should have described it in more detail. There, I can add as many generating devices to the system as I need. If I don't have enough power, I just add another generator to the system and forget about it. I can't do that here. Furthermore, the power sources have priorities. The solar panel has the highest priority, the generator has medium priority, and the battery has the lowest, and they work in tandem. So, if I don't have enough solar power, the generators will start producing the necessary difference. And the batteries act as balancers; if the system is low on power, they discharge and compensate, and if there's a surplus, they charge. The switches have separate input and output, which helps us better understand how it works.
There are also logic gates, but that's a separate topic, albeit a very interesting one.
