That is pretty darn cheap for an expandable slightly older generation EcoFlow delta series. ~.30 cents per watt is pretty good for new

Does DELTA 3 have the "Solar Priority" mode?
ChatGPT: EcoFlow DELTA 2
  • EcoFlow added a "Solar Priority" mode via firmware for DELTA 2 – in the app you can tell it to use solar first and only pull from AC once the battery falls below a set threshold, then top it up and go back to solar.
  • Effectively:
    • Solar + battery run your load.
    • If solar is insufficient for long enough and SoC falls to, say, 20%, unit switches to AC charging, then returns to solar priority once it's topped up.
If you want a "set it and forget it" box that does this, DELTA 2 is one of the more mainstream choices.

Yes it does. Has a much better battery than Delta 2 and has better cooling architecture. I bought this 1500 Delta 3 for about $100 less than this deal from EcoFlow direct via temu storefront a few months ago. Gets cycled every single day doing solar arbitrage.
