Experiences with Caterva Sun battery storage

Why interest-free loan? The storage system delivers 20 KW with a capacity of 21 KWh and is built by Siemens. Maintenance for 20 years as well as installation is included. This results in a break-even for Caterva. The device only pays off when it operates externally. Insolvency risk naturally exists but remains manageable. The storage system is owned by the customer and would, if Caterva actually failed with the control, behave like a "dumb" storage. The yield of the photovoltaic system would be around 80-85%. Only the premium would be lost. But even with one consumption, the unit would pay off within 20 years, with 10,000 already after 13 years.

Who consumes 10MWh in a private household?

Maybe the Kelly Family. But certainly not the average citizen with their 1.6 children. Not even if we also give them a pool for the summer.

Family, 2 children, heat pump, electric vehicle
There is more than enough

That was a good one too. No, it doesn't exist.

How many families does this combination apply to?

I would claim, vanishingly few, until you prove me otherwise.

The combination of a family with 2 (or more) children is already vanishingly rare. Add a new building from the last 5 to 10 years, and it's even less. And then the registration numbers of electric cars. Your 10MWh won't work out.

And such an electric car would still have to be driven 50,000km/year until we eventually reach 10MWh.

If you go back one page, you already have the first one with Matthias 2912...

By the way, the so impossible has happened at the beginning of the year: the shop has filed for bankruptcy. They say they are not out of the game yet, want to restructure ... we'll see.
