Air-water heat pump current consumption and data

So this means that especially with storage, 70% is strongly recommended?

If it clearly saves money and the inverter manages it correctly (meaning it doesn’t cut off early and then charges the battery), it can be used. The experts are called upon here. But despite intelligent charge management (e.g., distribution of charging power over the day), the battery can’t compensate for everything because it eventually becomes full, especially on sunny days when you are more likely to hit the limit.

So does that mean that especially with storage, the 70% are strongly recommended?

No, storage is generally not recommended. Economically it's nonsense, as it is still far too expensive (currently about a factor of 3 away from profitability) and ecologically bad, since they have to be manufactured with great effort and the stored amount of electricity PLUS the charging losses PLUS the operational losses are not available in the grid to replace coal power.

This could change in 10 years. But as of now, the only reason for storage is: hobby.

(Before someone comes at me now with a Senec/Sonnen-Cloud storage brochure: No, they calculate incorrectly.)

BUT: I can comfort anyone who is now sad because they wanted storage after all. Most of you already have one. Many even two. And in a few years it will be three or four.
These are: hot water storage, screed, first and second car. You can easily stuff 10 kWh of electricity into the first two. That should be enough for the night. And there are no electric cars with less than 50 kWh anymore.
What the additional 5 to 10 kWh in the basement (for almost as many thousands) are supposed to do... I don't know.

No, storage is generally not recommended. They are economically nonsense, as they are still far too expensive (currently about a factor of 3 away from profitability) and ecologically bad, because they have to be manufactured in a complex way and the stored amount of electricity PLUS the charging losses PLUS the operational losses are not available on the grid to displace coal power.

You are probably right there. In my case, the decision that no storage will be installed, not even Senec, at least as you already said, is not current. However, my concern was to understand another aspect of 70% soft or hard. And if someone has storage, that would be an additional pro for 70% hard, correct?

No, that is wrong.
For self-consumption systems with surplus feed-in (which most on the roof probably have), 70% soft only really makes sense from about 7kW module power with south orientation.

Ok, thanks to you. I will probably have to deal with it more closely soon. In my case, it will probably be around 11 kWp...

Ok, thanks. I guess I'll have to look into it more closely soon. In my case, it will probably be around 11 kWp...

The orientation can also be relevant for what the best solution for you is. But every (reasonable) solar installer provides sensible advice on that. Hard/soft/feed-in management, etc. My solar installer, for example, didn’t want to sell me a storage system at all because it wouldn’t be profitable for me – and that from a salesperson! There is also reasonable consulting ;)
