The root problem, as always, is that it has been normalized that devices in your house, accessed from your house, need cloud access to do this, or even to function all.
Metrics from an inverter, once upon a time, would have been a local web server in the device. Maybe with QR code printed on the device so the typical smartphone user could access it. Firmware updates ought to be physically "opt in" - like stick a USB stick or MicroSD card into the device and push a button.
Not some mysterious cloud that through legal issues, malice or sheer incompetence, can reach in and modify or delete functionality without warning.
My dishwasher has a little nag light to remind me I haven't connected it to my Wifi yet. I never will. It washes dishes just fine.

Or just a regular serial port! For example, IEC 62056 [0] provides a fairly trivial standardized way to interact with an electricity meter using an IR reader head. Even easier, the DSMR standard outputs serial data via a 5V RJ12 connector [1]. You can connect that to a PC with a $5 USB-to-serial adapter, directly to a Raspberry Pi, or to one of a dozen $20 cloud dongle thingies.
Just mandate a serial interface, and the inverter itself doesn't need any kind of web interface whatsoever.

Opt in security updates is generally bad. It means 99% will never ever get one.
Opt in for major functionality, that is fine.

No security updates needed if the device isn't connected to the internet in the first place!

Yes and no. Depends on the exploit.
If the washing machine is already vulnerable than you'd want a security update.

If the washing machine isn't connected to a network through what mechanism do software vulns become relevant?

If the washing machine can connect to WiFi then that's already a vector point of transmitting a payload by connecting to it.

I don't think that makes a whole lot of sense unless you're proposing bad actors are going to break into my house to...connect my dishwasher to wifi.

If opting out of security updates for your dishwasher is bad, then your dishwasher is shit.

Yeah, but what if a “security update” breaks functionality?
None of the IoT devices we own have had an update that fixes a user facing bug, but most have had critical updates that break existing functionality.
