Besides the model number matching, look at the bottom where the connectors are. It's the same as other rebadges like https://www.amazon.com/Inverter-I...B09H4LHMN5
This is assuming the pictures in the listing are representative.
I just convinced myself that I didn't need an AIO unit for my travel trailer...and now this deal is messing with my head!
My server rack & smart home equipment pulls about 600w 24/7 and so I just got 800w of solar panels to offset the cost some.
I have always been a bit of a mad genius with tech and I am no stranger to electricity as a former electrician and electronics engineer.
I could come up with crazy ideas, but specifically for this project I want to create something easy that anyone can do, without technical, electrical knowledge and no risks or violation of electrical code.
Right now, the honest answer is it looks like the Eco Flow Delta 3 Plus will do exactly that out of the box, so I just ordered one and when it gets here I can start tinkering.
The D3+ has 1000w of solar input
a 10ms UPS mode (fast enough for servers and such)
Hybrid charging so it can charge from solar + grid
Between these 3 features I think it will basically be plug and play, using the solar to charge the batteries, and then switching to battery automatically at a certian charge threshhold, but stopping before it drains too far so that the UPS feature is alwasy able to work.
If it doesnt work out of the box that way, I'll find a way to automate it with some smart switches and relays and such.
I doubt I will remember to come back here to share my findings, but I think its a cool enough project that I will probably share the info on YouTube if your wanna watch for it.

This setup makes sense when you want a lot of capacity cheap and need a lot of output, the core of a legit home system but if you just want solar to subsidize your grid power, you dont need a lot of battery basically you will use up all the solar as you generate it, and if not during the day anything stored gets used at night, as long as you never have any solar going to waste based on your input/output ratios your good and a basic D3+ I think will do that perfectly for me.
Is there even such a thing here in the US?

The biggest issue has to do with (and I haven't checked, I have a d2max, so your software may be different) is the inability for the unit to use solar when its on shore power, as the outlet is in bypass mode.
My lab features only allow you to chose when to AC charge and when to Solar charge. It doesn't let me configure beyond that. I believe the newer models may have that, that allows load shaving features. The only feature I have is the generator start/stop.

They look for a line signal, synchronize with the frequency and phase on the line, make the voltage just a wee bit higher (so that it can push into the line so to speak). Your home will then have a preference for that source.
Any excess energy would get pushed back to the grid. If the grid goes down, the signal gets lost, and it disconnects. (no shocking linemen issues).
If you don't have net metering, the energy goes to them for free.
You'll find these inverters all day long on amazon- just search grid tie inverters.

The EcoFlow Power Stream does just this, and I almost imported one and was just going to step it down from 220 to 110, but I would only do that if I was feeding a sub panel with only 110, as my main panel like everyone has 220 split phase and I dont get the warm fuzzies feeding 110 to the panel, while it should be safe as long as you do not meet one of two very rare conditions (multi-wire branch circuts, and 220v appliacnes that are actually multiple 110 in disguise) I would not ever suggjest it as most people dont have a good way to verify they are not going to hit one of those potential problem situations.
I saw people say the Power Stream started to come with a panel connection isntead of the outlet connection, so that might be a sign of changing the design for enhanced safety, and with a few more changes would be something the U.S. market can use.
Since unless you have a HUGE solar setup I don't see much point in feeding to the whole home, I am just going to setup a few isolated self contained systems to power my high demand stuff, as long as I am consuming all my solar power its the same net savings even if only part of the house uses the solar power, and it will be cheaper to impliment and no fear of legal or code issues.
I have an interlock switch on my panel and can pick and choose my circuits as the need rises or lowers so im not stuck with a default set or circuits that are hot with generator power.
The units in Germany as mentioned by madmax sense the hertz rate but also stop feeding for when there is no power from the grid so there is no backfeed. Friend has one in his "gartenhaus" which would be called a tinyhouse here in a 1/8th acre minit garden plot.
Ran some loose numbers and the stuff is still expensive here (for the hardware and low cost of energy) based on the formula below. If I use 20-40kwh per day and just try to supplement a bit it will be sadly more expensive in Germany where a 900W system runs 500$ max.
Energy (kWh)=Power (kW)×Sunlight Hours (h)×Efficiency Factor
Power (kW): The rated power of the solar panel in kilowatts (e.g., a 300W panel is 0.3 kW).
- Sunlight Hours (h): The number of peak sun hours per day, which varies by location (e.g., 4-6 hours in many parts of the U.S.).
- Efficiency Factor: Accounts for system losses due to shading, inverter losses, temperature, etc. A typical value is 0.75 to 0.85.
Example CalculationIf you have a 300W panel, receive 5 peak sun hours per day, and use an efficiency factor of 0.8:
0.3×5×0.8=1.2 kWh per day0.3 \times 5 \times 0.8 = 1.2 \text{ kWh per day}0.3×5×0.8=1.2 kWh per day
- Sunlight Hours (h): The number of peak sun hours per day, which varies by location (e.g., 4-6 hours in many parts of the U.S.).
- Efficiency Factor: Accounts for system losses due to shading, inverter losses, temperature, etc. A typical value is 0.75 to 0.85.
Example CalculationIf you have a 300W panel, receive 5 peak sun hours per day, and use an efficiency factor of 0.8:0.3×5×0.8=1.2 kWh per day0.3 \times 5 \times 0.8 = 1.2 \text{ kWh per day}0.3×5×0.8=1.2 kWh per dayhttps://youtu.be/ut6LA5faRmI?si=

I'm not sure about this specific model but it should be compatible with solar assistant which gives you better control and stats.
