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?

Don’t get defensive right away, I’m asking honest questions and don’t mean to embarrass you or anything. I’m genuinely interested in your answers and experiences. I don’t have much space in the house either and have already thought about where and how to place a battery. Wrapping it in insulation inside my garden shed was also an idea. That’s when I came across the problem of overheating.
But if you haven’t had any issues with that, I guess it might not be such a big problem?
Otherwise, maybe air conditioning wouldn’t be a bad idea. It wouldn’t need to cool down to a comfortable 20°C (68°F) like a regular air conditioner, but just prevent the temperature inside the insulated box from going above 40°C (104°F)... and then you could even skip the frost protector and just have the AC inside.
Are there air conditioning units that can be set over such a wide range? Like doing nothing between 5°C and 40°C (41°F and 104°F), but heating below 5°C (41°F) and cooling above 40°C (104°F)?
That would be interesting... I just started using it recently... and mine is standing in the garage. I can imagine it would probably get too warm in the garden shed, but in the garage?
I’ll report back during summer... if necessary, I might have to remove the cabinet door in summer.
Mist, I made the mistake of switching electricity providers too early out of panic... I was afraid they wouldn’t accept me anymore. Now the old provider increased the price to 33 cents and the new one to 43 cents, grrrr.

WilderSueden18 Nov 2022 22:35I doubt that the air conditioning pays off. It shouldn’t get above 40 degrees Celsius (104°F) in the garage, just as little as inside the house. A closed insulated box is of course a completely different matter; in that case, you’d probably overheat the battery if the garage warms up in summer and the battery is then used extensively. I would definitely open the box during the summer.
I would like to order the BYD Premium HVS 7.7 storage system now. However, I am concerned that it may not be compatible with my SMA inverter (STP10.0-3AV-40). I haven’t been able to reach anyone at SMA, and my installer is currently unavailable. Why does compatibility have to be an issue again? In BYD’s compatibility list, only the SMA SBS and STP SE models are mentioned. Does this mean I ultimately cannot use this battery?

RotorMotor1 Mar 2023 11:26SMA has only recently started offering hybrid inverters, which are inverters that can connect not only photovoltaic modules but also batteries.
The hybrid model is the SE; if you don’t have that, you will need a separate inverter for the battery.
Whether this makes sense or not remains to be seen...

Does that mean I can’t use this battery after all? I asked my solar technician. Your SMA inverter is the blue box, right? So, the "non-SE" version? If that’s the case, it’s not compatible. You need the "white box," which is the "Smart Energy" model for BYD HVS and HVM.
I have the STP 10.0 myself along with a BYD HVM, and I was a bit worried at first, but I was offered the "SE" version.
