Open Sentinel and read your installer the code.
Download Sentinel and open it on a computer on the same network as your inverter. It shows a six-character code — read that code to your installer so they can connect. Nothing is shared until you tap “Let your engineer look at your system” on your own screen, and anything that changes a setting needs a second, separate tap. Both permissions run out on their own.
Mac (macOS 11 or later): on first launch macOS shows a “cannot verify” prompt — open System Settings → Privacy & Security, scroll down, and click Open Anyway. The first time it searches, macOS also asks to allow access to devices on your local network: that one matters, because your inverter is a device on your local network and Sentinel cannot find it without it. If you tap Don’t Allow by mistake, turn it back on under Privacy & Security → Local Network.
Windows 10/11: unzip and run Sentinel.exe; on first run click More info → Run anyway. Sentinel needs Microsoft’s WebView2 runtime to draw its window — that’s already on Windows 11 and nearly every Windows 10 machine, and if it is missing the app offers to fetch it. If Windows blocks it flat with no “Run anyway” option, that is Smart App Control, which only allows signed apps and cannot be told to trust one: use the Mac app for now, or ask us — a signed version is on the way.
Both prompts appear because we haven’t yet bought a code-signing certificate, not because anything is wrong with the download. We’d rather say that plainly than have you wonder.
