Photovoltaic system with hybrid inverter without internet connection?

Well, it depends. As long as the main line for fiber optic/cable is already laid, there can definitely be people with different priority levels who get it faster. For example, my neighbor moved in 6-8 months earlier, but I had cable internet first... Hehehe.

Just a short feedback here.

Thanks for the tip about the mobile router. We bought it at Lidl for little money + a 3GB prepaid card. This setup works perfectly. The photovoltaic system was put into operation on 20.06.
Yield as of today - 525 kwh.

So far, almost the entire yield has been fed in. In about 10 days, we will start the screed heating program. I hope that by then at the latest, the earlier installation of the system will really pay off.
