Hello,

there are frequent concerns about the potential fire risk posed by batteries in photovoltaic systems and how difficult they can be to extinguish. I would be interested to know where you have installed your batteries and what precautions you have taken in case of fire. Photos are also welcome!

Thank you!

That was probably me 🙂 It’s a Sungrow SBR096 battery with 3 modules at 3.2 kWh each. It can be expanded up to 8 modules. One module weighs about 33 kg (73 lbs).
The "three-module tower" measures approximately 625 mm (25 inches) wide, 545 mm (21.5 inches) high, 330 mm (13 inches) deep, and weighs around 100 kg (220 lbs) including the base and cover.

We have the same one, just the "four-module tower" =)

Are there regulations about where it can be installed? Can it be placed directly next to the heater or under the electrical panel—in other words, basically anywhere there is space—or do certain clearances have to be observed?

No, it doesn’t matter. The only guidelines come from the manufacturers regarding the distance, meaning the maximum cable length between the inverter and the battery. Generally, a battery does not like to freeze, so it should not be stored in very cold conditions.

Distance requirements only apply to the electrical connection boxes and distribution boards in the respective main distribution board (MDB).

Would you say that the statement "the topic of photovoltaic batteries (similar to heat pumps) in private households is still relatively new in our regions, and building regulations have not yet caught up" is accurate?

No, we would not say that.

You have often read already that LiFePO batteries do not pose any special risk and therefore do not require separate consideration.

You have already read many times that LiFePO batteries do not pose any special danger and therefore do not need to be treated separately.

There are no special hazards with gas heating systems either. Yet, there are specific regulations in place. I’m not trying to demonize the battery—in fact, I’m planning to use one myself. But here in our regions, there are regulations and requirements for EVERYTHING. Just not for this? That’s why I’m asking.
