Inverter, what should be considered?

I wasn’t planning on getting a storage system anytime soon anyway, but that really deflates the whole storage topic for me even more. 2.6 KW is really not much. 6.5 KW is more like it, but how much more does the storage system cost then?

So, I cook a hot meal almost every evening, and it’s not always the P setting that’s used (which would require over 7 KW, if I remember correctly), but definitely the second highest setting and often several zones at once or oven and stove simultaneously. Then, of course, the TV is already running – no idea what it consumes – 250w? Lights everywhere and the server. Meh...

The most important point would certainly be the confirmation of the ability to deliver at the specified time.

I probably should have named the thread title: "Inverter, what should be considered when designing?" ;)

No, you're right, there are certainly some who haven't yet thought about the fact that there are currently quite significant supply shortages.

I completely agree with you, Tolentino, I have the same consumers and I can already see myself getting annoyed :confused:. I don't even know, does the heat pump still count in there? The controlled residential ventilation? (You could also mention the electric car, although that would bring other problems, so let's leave that out :).) A possible air conditioning? Expandable as desired...

Not everything is always running at the same time and in parallel, but you do get a bit of a feeling of what this could lead to...

All of that, yes. You wouldn't load an electric car from the storage. At least, that should be avoided if possible. Normally, you charge that first and then the storage. Depending on the required routes, you can also drive the five workdays of the week on one battery charge and then fully charge it on the weekend - it depends.

I totally agree with you Tolentino here, I have the same consumers and I can already see myself getting annoyed :confused:. I don’t even know, does the heat pump still count in there?

Expandable at will...

As I said, how often do you use your cooktop in P mode?
Few seconds to minutes.

You don’t charge the car from the home storage.
Heat pump and air conditioning usually not either (but they rarely if ever need over 1kW).

Controlled residential ventilation, server, etc. he of course supplies, they also run at night.
But all that together is then about 200W.

As I said, a storage should be designed as a base load supplier, it can of course also balance peaks but is not primarily meant for that.

It’s always like this: squeezing out the last 10% (self-sufficiency) then costs 80% more. ;-)

Exactly here is the point, the calculation in the video was exactly with this inverter, actually 6.5kW, but at 13A. And he somehow implied that this is the crux.
Could the voltage of 200V at the battery have something to do with it?

What kind of battery did he have?

Yes, but it is sad that the amount of electricity in the storage should actually be enough, but you can't get enough out in one go. And P already needs over 7kw. 7 or 8 (my standard cooking levels) are enough and they already push the 2.6 to its limits. I would just be very disappointed because this is really not an edge case but something absolutely everyday.
