Something like Ecoflow Powerstream would be nice

SolarFlow looks to be a nice solution although there are some issues at the moment which hopefully will be solved soon.

But SolarFlow isn't compatible to Superbase power stations. Ecoflow as competitor to Zendure introduced Powerstream which is compatible to some of their power stations.

It would be nice to get something similar from Zendure to use the Superbase power stations in the same way.

Yes, you can plug solar panels to the Superbase but the solar power wouldn't be used if the Superbase is also plugged to the AC input for UPS mode. And if the Superbase is fully charged the solar input is shutting down. So you can't use the more solar power you probably can get for other devices.

The SBV shutting down AC output when fully charged is actually a bug which they have tried to mitigate in a firmware update several weeks ago. However it isn't fully fixed and is still occurring every few days at least on some devices. As a workaround, setting the maximum state of charge limit to 97% usually helps. This in turn might lead to inaccurate state of charge reporting, and the issue may still reappear, so it clearly isn't a good final solution, but I hope that one day the developers will learn how proper battery management works and will fix the underlying firmware bug. I've sent them a detailed report of what the root cause of that issue is and how it can be fully fixed, but I haven't heard back about this for several weeks now. Some way to allow AC input to only be used when the battery is running low would also be great and they promised in an email that this would be implemented later this year, but I'm not very hopeful that they will get that right, given all of the other battery management issues. The real killer in the comparison to EcoFlow's approach is that the SBV can't be used with a grid-tie inverter, and I don't think that will ever change. It would require the introduction of an SBV-specific grid tie inverter, which requires a lot of certifications, which they obviously didn't even want to bother with for SolarFlow, sacrificing a lot of efficiency and risking compatibility issues. We've seen how that decision played out.

I don't have issues with AC output. My SBV works in UPS mode without issues having Limited the battery charge to 90 % and 400 W AC charging.

true, but we could use the xt90 from the satellite battery to connect a grid tie inverter, so some messure are possible....

I don't think these work if the satellite is connected to an SBV.

rex

it is an output, no different than other outputa on the battery. I see no reason it will not.

my understanding is that the circuitry used for the XT90 port on the satellite is repurposed for crossfeeding between batteries when they are linked. at least it doesn't work as a solar input anymore once the they are linked. At first I thought that my device was faulty, so while diagnosing I configured it as an output and I think that didn't work either. Only later I found out that this happens whenever the battery is linked to an SBV (or another satellite - in that case, the XT90 will work only on the satellite that has the master role).

thanks for the info, support told me in Q1 2023 that I could connect solar inout simultaneously to sbv and satelite while they are connected. so another "quality" support and guidance from Zendure support

Yeah I was under the same impression when I made my purchase decision, however it evidently doesn't work. Is this fixable? Perhaps. It might be possible to make firmware clever enough to to only repurpose that circuitry while actually crossfeeding, but perhaps there are hardware limitations preventing that. Difficult to tell without schematics or at least teardown photos of the device. Support didn't even bother to answer my questions about this, they just closed that ticket without any reply at all.
