Maybe some of you have seen the short report on SWR about the Senec batteries that literally went up in smoke. Unfortunately, my wife saw it too. The battery (Varta) is installed in the basement and is waiting for final installation by the electrician. She is starting to get cold feet and doesn’t feel comfortable having it installed. What do you think about this? Of course, it’s clear that any battery device can catch fire or explode, or that there is a higher risk of an electrical fire somewhere else. But I can’t deny that it is still a very large lithium battery that is almost impossible to control if it catches fire due to a short circuit or defect.
I’m asking for advice on what precautions can be taken or what your thoughts are on this. Does anyone know if in case of an incident this would be covered by the home insurance policy or if it needs to be reported separately?

Why? Should we? The battery doesn’t generate any heat…Seriously? Every battery I know gets warm when it is charged or discharged heavily. And they become less efficient when they get very warm.Bausparfuchs schrieb:
Therefore, I find it a bit surprising when a 28 kWp system produces only 4.5 kWh. There isn’t much to be surprised about with all-day rain and not a single hour of sunshine in November...
Today 29.3 kWh.

But of course, the sun can’t shine everywhere.

In November, here in the Rhine Valley in the southwest, we already have several rainy days. Since yesterday, there has been thick fog all day. Today, we produced an impressive 3.3 kWh (3.3 kWh), which I find remarkable considering the dense fog. The system capacity is just under 10 kWp.

Does it get its own climate control?Don’t go into defense mode right away—I’m asking honest questions and don’t intend to embarrass you or anything. I’m genuinely interested in your answers and experiences. I also don’t have space in the house and have already thought about where and how I would place a battery. Wrapping it in insulation (in my case, a garden shed) was an idea too. That’s when I encountered the problem of overheating.
But if you don’t have issues with that, it probably isn’t that serious?
Otherwise, a climate control system might not be a bad idea. It wouldn’t need to cool to a comfortable 20°C (68°F) like a normal air conditioner but just prevent the temperature in the insulated box from going over 40°C (104°F)… then you could also do without a frost guard and only have the climate control inside.
Are there air conditioning units that allow such a wide temperature range? Like doing nothing between 5°C and 40°C (41°F and 104°F), heating below 5°C (41°F), and cooling above 40°C (104°F)?
That would be interesting…
