OK. I am starting my research with PV (solar) inverters/chargers that work offline (meaning no cloud, no internet needed, LAN (local network) is fine) but not off-grid :) I hear good things about the Victron Multiplus series that seem to work that way: https://www.victronenergy.com/inverters-chargers/multiplus-12v-24v-48v-800va-3kva and the Multi-RS Solar that adds MPPT: https://www.victronenergy.com/inverters-chargers/multi-rs-solar@[email protected]
@fedihouse If you know (from experience) about similar devices that charge and feed power without phoning home all the time, feel free to add them to this thread. I will collect them on a page at https://fedihouse.eu
@fedihouse Not very surprised to find out that such inverter/chargers exist in quite a few niches. The marine sector, for example, has a need for such configurations. On-grid when harbouring but offline on the sea. Also: RVs.
@fedihouse And before you suggest devices, please make sure you know they work without internet connection. Ideally from experience. Throwing devices around that you've only heard of but not used isn't really helpful :) I am collecting devices that fit the requirements in an issue thread at https://codeberg.org/jwildeboer/fedihouseMirror/issues/2#issuecomment-8046989 where you can also add yours, if you prefer it that way.
The Penguin of Evil@jwildeboer @fedihouse Stuck a comment on the github one but worth noting that Deye==Sunsynk==Sol-ark for different voltages and sales markets.
Also you need to distinguish between "off-grid" and "not grid tie". Here (UK) people make extensive use of non grid tie but grid input inverters in things like outhouses or small setups because there's not yet any 800W plug in solar setup (technical reasons to do with ring mains and our plugs, plus political reasons to do with stupidity)

My Goodwe GW3600NS worked fine without internet-access. https://brnrd.eu/misc/2019-03-23/killing-the-internet-of-shit.html
It died earlier this year, and I'm just about ready to find out if the new GW3600DNS works without.
The goodwe python package extracts all data just fine

The only IoT device in my LAN is the inverter (ca. 400V DC to 230V@50Hz AC) for my solar panels. I don't like devices that do not/can not update in my network. Now that the website I used to pull the measurement data from is changed (and thus broken) I decided to reverse what the device does and build my own service.
donburi@jwildeboer @fedihouse Solis S5 series. Although the installer fitted the wifi dongle that connects to China, it runs perfectly well with it pulled out.
And, as it happens, with my home-automation controlling it.
Pino Carafa@jwildeboer @fedihouse oh I'll be following THIS conversation
John Carlsen 🇺🇸🇳🇱🇪🇺Recently someone mentioned the Anker F 3800 and its expansion batteries.

Martin Williges@jwildeboer @fedihouse My Kostal Plenticore G2 works offline, grid tied. Plenticore G3 ist able to work without grid (maybe limited time?). Also, Open API for easy interfacing (iobroker, openWB etc).
Updates via web interface from downloaded file ist possible.
Downside: Kostal Cloud ist a mixed experience (recovering from an outage on 2025-10-27 Not done yet). Grid parameters are not changable as a normal user.
