Title reads like at ad, but this is a new way to reach energy independence. I actually have a small EcoFlow device and it’s pretty good for the price.
I hope this tech can be made available in the US soon.
The cables in your walls are designed for a certain maximum current before they start to heat up. This current is limited by your breaker.
Now if you introduce a plug in solar setup your current is limited by your maximum breaker capacity + whatever your solar setup can generate.
So if I’d use the specs from the article and apply it to a normal dutch home situation: 16A breaker, + 800W at 230V, which means ~3.5A = 19.5A max. which is probably still fine for short durations.
But now some genius doesn’t read the fine print and hooks up 2 or 3 on the same circuit. There is no electrician that tells him that’s dangerous because it’s all self installed and he doesn’t know any better. And all of a sudden you are up to 26.5A and you got glowing, smoking wires in your walls…
Ok sure, that makes sense. This might actually be an issue.
Your breaker will pop. Just like if you were to run a hair dryer on each outlet.
The breaker only sees the current flowing through the breaker though. Not the additional current provided by the solar panels since those don’t flow through the breaker. So it will pop later then that the cables are rated for, therefore introducing an overheat and fire hazard.
Maybe for a same-circuit device that’s consuming more than the breaker can provide? I don’t know enough about this tech but would expect this can be accounted for in some way.
