ᐅ Any experiences with purchasing batteries with more than 1 kWh capacity?

Hello,

we are considering using batteries instead of a generator to be prepared for possible power outages. However, all devices with more than 1 kWh capacity quickly cost a thousand euros or more. The question is whether it is worth it. If the grid ever fails, the investment would probably be worth the cost?!

Regards

How long do you plan to keep going? And what about the electricity?

With an annual consumption of, for example, 5,500 kWh, you have about 15 kWh per day, so with 2 kWh you would last around 3 hours.

Is that investment worth it to you?

Well, if I can bridge upcoming power outages for the most important parts of the house, I will be glad to have taken some action...

Then you have your answer... For me, it is unlikely that there would only be power interruptions if anything happens. It would either be completely off or fully running.

Define your scenario:
- Duration and frequency of power outages
- Critical loads ("the most important")
- Comfort loads

The freezer chest stays cold for up to 2 hours without power. For 3 days, probably not, but then the lack of heating becomes a bigger issue than a spoiled pizza.

As far as I know, there could very well be local outages. Nationwide blackouts in Germany are expected to be comparatively rare events.

Yes, you’re right there. Luxury items won’t be supplied with such a device. That’s logical.
Duration and frequency of power outages – well, who can predict that?
