Yes. Covered and they drop you afterwards.

Dozens of homeowners say insurance companies lowballed or denied roof damage claims from hail
The I-Team has heard from 75 people in the Chicago area and Northwest Indiana who say their insurance claims for roof damage from hail were either lowballed or flat-out denied.

If my previous comment wasn't fully descriptive, I am talking about fire not water, weather, and other hazards.

Depends on the insurance agency and agent I guess.
I would think since you didn't intentionally set your house on fire, it would be covered. It was an accident.
How many appliances or thing in your house do you use that isn't UL Listed? That would be a cool thing to look into

Well you can find it if you actually LOOK. There are plenty. And there is no difference between denying for fire or weather. It's still denying coverage people pay for.
In coast guard safty classes dealing with gasoline engine boats we were taught how gas can explode or not explode in other cases.. ( basically the right oxygen mix is needed..) fire can happen much easier…BUT . If the mix is correct and gas is vaporized it is scary how many sticks of TNT power are contained in a small amount of gasoline , much less a whole gallon..
I say it could easily destroy a good size house , if not blow the whole roof off and lay the walls down .
lot of variables must come into play but it’s easily possible.
Click baiting the title has become the norm on most of the MSM now days…
I'd say this particular situation was a natural gas explosion from my experience. I have dealt with several of them back when I was on the fire department. And that area where the batteries are is not showing signs of any explosion from within the cabinet. A gasoline explosion would be a possibility but this doesn't appear to be one of those.
You have a good eye it seems ..….This was 4 or 5 miles across the mountain about 4 years ago in a very upscale niegborhood…
a small landslide , they say, ruptured a gas line , caused a leak in the lines feeding the house and kaboom while the owners were home.. both died on the scene..
this was a very big nice home… total bummer if ya ask me..

Well it's kind easy actually. There would have been obvious signs of burning on the cabinet the batteries are in. Plus looking closer they actually look pretty good for going through an explosion. There is zero obvious burning anywhere however. When gas lines rupture and explode they will burn only at the line. Usually it will actually blow the fire out as in the one your photo shows. No more fuel no more fire. And instantaneous explosion is what occurred in your photo and the one in Germany appears to have been the exact same thing. When I was a teen is was going somewhere one early morning and as I drive past a pizza shop I see the owner going in the door with a cigarette in his mouth and as he opened the door, kaboom! The building blew up. No fire at all after the original explosion but you could hear the gas coming out of the line into what used to be a building. The owner died. Cinder blocks were thrown across all 4 lanes of road. Pretty scary stuff and I had a new appreciation for natural gas after that morning.
that’s a good question…I have no idea… still a bummer…

You can distinguish a natural gas explosion from hydrogen?
Common sense actually. If a battery had exploded you would see it in that photo. Zero signs of a battery explosion, and I mean zero.

I don’t think venting gas would require a battery explosion.

This whole discussion has been a fascinating. It's all over the map!
I am personally interested in designing my systems for events that happen at the margin. It's those moments that I want things to work the most. Heat, electricity, etc
I have no idea how well all of the battery cells I purchased recently are built. Possible that they crack, have a manufacturing defect? What about the BMSs?
What IS interesting and important to me, is what could happen if something goes sideways. And, a LOT of things seem to go sideways on a regular basis. Why are so many people in this thread getting their pants in a wad because some are thinking through the potential next evolution of battery safety?
One of the things I started thinking about when looking at the earlier posts about the battery study (I did not read it yet) was, what if any "tells" are there that we can easily / cheaply look out for to detect a run away cell / event? These little ESP32 boards are so cheap and easy to program...could we not monitor cell voltages to detect a run away and then open a disconnect device and/or turn on a venting system/alarm?

A typical BMS does that already. In order for thermal runaway to occur in LFP, an external heat source is required - at which point your BMS will shut everything off. If the cell voltage in a cell suddenly drops, the BMS will shut it all off. If a cell voltage goes too high, the BMS will shut it all off. So any energy going in or out of the battery will be cut off in case an anomaly cell event occurs.

Thanks. But, if the BMS fails...then? I know all of this is unlikely, but then again, my house burned to the ground a few years ago. I didn't think that was likely either. It had nothing to do with batteries, solar, or anything other than an unlikely chain of events.
Shit happens.
I am wondering if there is a simple means to detect and deal with an off-gassing event.
Indicators:
over/under cell voltage
ambient temp
gas level detection
Solutions / Aids:
steel / fireproof enclosure
battery disconnect
passive pressure release
active venting
I have 8 batteries to put together. This type of stuff was already on my mind. I have no idea what happened to this guy's house. But, I do believe that LiFePo4 batteries, while very safe for the most part, can be very dangerous in the right conditions. I am curious what might be easy ways to detect if any/all of those conditions are present.
I am already considering things like a 200a contactor on each battery...more sensors is not a huge deal for me.

Best thing to do: don't have the batteries in the main house. In my case, they are in the same building where the wood boiler and water filters are located. No matter what technology you put in place to detect things: it can fail. So how many redundancies is enough? Each battery is fused, the charge controller and inverter configured properly to disconnect on over/under voltage, the BMS as a protection device, and cells not charged to more than 3.5V or so. If the building is then ventilated properly (as it should) there is nothing more you can do except get insurance that covers everything should things go wrong somehow.

Design correctly! Then maintenance regularly! These two things will mitigate most issues. There are always accidents.

Catch, make or grow everything you can.
Plus one +1
That’s why , as I stated in previous posts , all of my gear and batts are in aluminum trailer ,
18 ft away from any structure… panels are 50 ft away…
The only connection to where I live or sleep is the RV factory 50 amp shore power cord..If ever see the trailer aggressively smoking out of the seams or cracks , ( conditionally) I probably won’t be opening or trying to stop it..giving it more oxygen won’t solve anything…I will go get a beer , grab a yard hose to stop any spreading but that’s all…
and no , I have no insurence at all on any solar stuff ..
Some times it just ain’t a good day…
