  • I installed an 24 kWp solar system on my residence this summer. Before I decided on a company I called in offers from 6 companies with the explicit wish that no Chinese or American compnents are used. Only one company took that wish seriously and actually made me an offer using only European made hardware, they were 16% more expensive than the cheapest offer but ultimately got my business. I specifically want to be able to have power in a crisis which is why I also got a large battery installed, all of that would be no good if some malicious state actor could just disable my system.

    My inverter is actually from Fronius and the company had issues getting it online at first because the setup was relying on Microsoft Azure which is blocked on my network. We got it working by installing the initial firmware update locally though. Afterwards we disabled all remote control features and I firewalled everything so it can’t connect to the internet. The installer company will contact me if there are any important firmware updates but otherwise my system will stay offline.
