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]

@jwildeboer @fedihouse Victron inverters are, in my experience, noisy as hell. I would not have one in the house — would want it in an outbuilding or somewhere reasonably sound-damping. Models in EU may, of course, be different (I'm in S Africa).

I have a 5kW Deye inverter, and I've only ONCE in 2½years of operation even heard it at a whisper when we had it under near-max load. My setup is completely off-grid and not networked in any way.

@jwildeboer @fedihouse
For clarity, most/all of the Deye inverters are cloud-optional and grid-capable (but not necessary).
