Help with photovoltaic decision

The last thing I am interested in regarding photovoltaics is power outage security, to be honest

I’m not getting any younger either, but I can’t remember a power outage lasting longer than 5 minutes. The equipment I can use 24/7/365 and actually do is worth every penny to me. The world is just that different.

It would be great if you could combine both. That is, when bidirectional charging finally arrives and you can save yourself the extra storage. It is so nonsensical to have another storage installed in the house when a sufficiently large storage is right outside the door. And all because politics isn’t getting its act together.

My car, which I am getting next Wednesday, can do that. I just don't have a suitable wallbox (there is only one provider). And I also can't use it additionally, because my employer pays for the electricity charged at home.

There are probably already more suitable wallboxes, Google says.

There are probably more suitable wallboxes, says Google.

Only one that communicates properly with VW and is approved. But as I said, it’s forbidden for me anyway.

Hi,

I always thought the same:

It is so absurd to have a storage system installed in your house when there is a sufficiently large storage right outside your door.

Besides the obvious sluggishness of German politics (the main problem right now is probably that the authorities do not know how to treat the case "Someone is allowed to charge their car for free at work and then uses the employer's free electricity at home" for tax purposes), the problem is also not trivial technically. Unlike an internal home storage system, your wallbox is not connected to your inverters but directly to the power line. In other words, if you want to supply your house via the wallbox, you first have to completely disconnect from the power grid. Otherwise, you feed the contents of your car battery into the public power grid and end up with an empty battery in the morning.

And with that, you face the same problems as with implementing an island solution. Automatic switching, uninterrupted... that is not easy.

Best regards,

Andreas
