Please note that you need an Ecoflow powerstream (which is different from the Stream) to use the delta for charging and discharging on demand. Without the powerstream it will be a backup battery. Unfortunately these powerstreams are no longer available in shops and are expensive secondhand. I just bought one on the german Ebay (.de), where they are still reasonably priced. You will need a german address though to order with shipment or use an international shipping company in between.
The powerstreams were originally sold in 600W and 800W. Apparently the hardware is the same and you can upgrade them for free with a software update to 800W. More than 800W is not allowed through a wall socket.
I donât know if the delta 3 works with this app. I bought a delta 2 with still 100% SOH secondhand. You could consider this as well. It looks less sleek, but had more ports. In the ecoflow app you can see the SOH in the settings.
