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
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.
