ᐅ Photovoltaic Battery Storage – Market Overview and Fire Risk

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?

On the AC side, this means using a battery inverter, which is the standard. I have a BYD HVS 10.2 with an SMA Sunny Boy Storage inverter in the basement.

The storage system we are planning uses lithium titanate (LTO) cells. They do not catch fire even if mechanically damaged and remain fully operational at -40°C (-40°F). Disadvantages: low energy density by volume and high cost.

I built my storage room inside the garage… It isn’t connected to the house. So it can burn down if it wants to (-;

Is the garage heated, meaning warm and dry enough?

Frost protection … and the storage tank is insulated … a garage doesn’t usually get that cold … plus, the storage tank is designed for that.

Or are you planning to park your electric car inside the house? How else would that work?

Most electric cars preheat the battery either before or during charging. I haven’t heard of this being done with home energy storage systems yet.
