ᐅ Fire Risk of Photovoltaic Batteries: What Are the Installation Options?

There are no special dangers with gas heating systems either. And yet there are certain regulations. I’m not trying to demonize batteries either; on the contrary, I’m planning to use one myself. But especially here in our region, there are regulations and requirements for EVERYTHING. Except for this? Hence the question.

I still don’t understand what gas heating systems have to do with storage systems...

But the statement regarding that is simply wrong.
Gas heating systems carry very real dangers. They constantly burn fuel, producing heat and exhaust gases. Both pose a real risk to people if not properly managed.

In electrical storage systems, chemical processes occur that do not pose a danger.

Except for the gas line inside the house or within the gas heater itself. It hardly gets more specific or "special" than that. Even the smallest leak can turn your home into a smoking crater in a matter of seconds.

Here in the neighborhood (gas infrastructure installed about 40 years ago), where I currently have a direct view of the house, there was actually a gas line leak in the basement several years ago. It was so severe that the entire neighborhood smelled strongly of gas. So, the fire department was called—my brother was there at the time as well—and when they arrived, what did the chief do first? Ring the doorbell! The house was still standing, and the rest of the neighborhood was fine, but the chief ended up losing a 100-liter (approximately 26-gallon) barrel at the next summer event because of it.

The fact that things turned out just fine this time doesn’t mean it was safe.

Oh, now there’s another argument being made to discredit gas heating 😉

Natural gas is quite easy to detect thanks to odorization. Heat pumps have also caught fire due to technical faults.

Gas accidents get immediate attention because they make it into the media. A house explosion appears on major news programs, while a heat pump fire might only be reported in the local paper.

And if it’s not the storage tank, it’s the inverter. That can catch fire too.

There have even been houses burned down because of a faulty toaster. This discussion doesn’t lead anywhere. Let me state this clearly: there are no specific regulations on how to install the battery storage. For me, that means it should be placed where there is space and it makes sense. It should go without saying that you shouldn’t run a power cable across the room. Installing it in an unheated extension also doesn’t seem very practical.

Once again: If there was an increased fire risk, the insurance companies would have already taken action. But they have not. These companies employ smart people whose entire job is to assess risks all day long.
