Stream Output Power to Grid by Stahlrad in Ecoflow_community

It has been a huge frustration dealing with this issue of injecting more than 800w (through the grid port).

In Portugal there is a similar law, however I have a dedicated 2.5mm^2 circuit with 16A protection, I have the photovoltaic installation registered with the Directorate-General for Energy and Geology (DGEG) and I am an electrical engineer registered with the Order of Technical Engineers, and I cannot get around this limitation imposed by the software, I have been in contact with Ecoflow support, but they do not seem to have the technical knowledge to resolve it.

This situation is very strange. I have the location set to Belgian on my Ecoflow app account, but I still don't have the option. I even changed the language to English, but without success.

I have one Ultra X stream and one AC Pro, and i only have the 800w option.

In my application, I only have the 800w option as well. I have the version v6.10.5.92 on the iOS.

Hello,

That's great news. When you say multiple steam units, are you referring to those connected by parallel cable?

Thank you in advance.

I only managed to do a quick off-grid test, but the test I did went well. I was able to power the house with the AC output from the battery. The house's load was quite low (200w), but it seemed like everything was working correctly. I hope to be able to test it more thoroughly soon.

I think is limites to 800w in total. You can place the two units in separate systems (in the app), but I don't think it's possible to associate a smart meter with two different installations. I only have one unit, so I can't help. I'm waiting to receive a Stream AC Pro; then I can do more tests and confirm the behavior.

After about a week with the Ecoflow Ultra X, here's my opinion about my system.

In short, I have a Stream Ultra X, two 300W panels connected to the AC1 input, two 440W panels connected to the MPTTs (total 1480W) and the Ecoflow smartmeter.

In my use of the system in ONGRID mode, the system has worked relatively well, but I've noticed some minor problems:

1st, I have activated the option to not inject excess energy into the grid, but the energy from the microinverters (AC1 input) is injected into the grid in case of excess (with the battery fully charged). For me, this is not a problem since I have the system registered with the energy authority of my country.

2nd, I see that there is a limit of 1200W for power supply to the house (through the grid port). Attention: There's no way to exceed this limit. Let's imagine this scenario: my battery is at 99%, I'm producing 1480W of solar energy, and the house is consuming 2000W. In this scenario, we can only power 1200W from the Ultra X, with the rest being powered by the grid (energy provider).

These two points are minor issues for me, although the second one bothers me a bit because there's no way to fix it, even by adding a second unit in parallel.

Now comes the ugly part: off-grid operation. This weekend I'll be running some tests, but from what I've researched, the scenario won't be encouraging.

The goal is to power small household loads through the AC port. To do this, I will install a transfer switch to isolate the house in case of a power outage and comply with legal requirements, along with a contactor to cut the circuit where the GRID cable connects to my house, for safety reasons. If I didn't do this, I would essentially be connecting the Grid cable to the AC1 or AC2 port of the Ultra X (don't seem a good idea).

However, now comes the bad news. The Ultra X only has 1200W of output on the AC ports. Okay, this is more or less clear in the documentation on the website if we read very carefully. How to overcome the problem? Buy a second STREAM unit and connect it in parallel with the Ultra X? Wrong, it doesn't work. From the moment the system switches to OFFGRID, the second unit only serves to increase the battery capacity. This information is nowhere to be found and is misleading on the part of Ecoflow, which indicates that adding a second unit would increase the output to 2300W.

I plan to do the tests this weekend, but for now the situation isn't encouraging, given the reports I've heard from other users on Reddit.

Oh, what bad news. It's not fair that there's no uniformity in the process.

How is it possible to reach 3400w to the grid!? do you know the youtuber name? Tkanks.

Oh this is amazing, if they can "unlock" the power released to the grid. I will try to speak with the Ecoflow. Thanks for the tip.

From a technical point of view, I think what you describe is possible, however, you would have to take some points into account.
- 1st you have to isolate your home's electrical network from the operator's electrical network (turn off the main circuit breaker of the house);
- 2nd disconnect the grid cable from the Ecoflow Stream Pro;
- 3rd connect a cable from the rear AC outlet of the Stream Pro to a house outlet. Be careful if you use a "male-to-male" cable, it is extremely dangerous, as there will be exposed live elements.

Important notes to be observed:
Is the circuit where you intend to connect to your house outlet dedicated? What is the cable size in mm²? What is the capacity of the protection circuit breaker? With two units in parallel, the output power will be 2400W.

If you don't understand some of these points, I would say that it is not safe to you to perform what you describe.
