What an 8 year old failed battery bank looks like under thermal imaging

Recommended Posts

Hi Guys,

New to the forum and i thought i'd do an interesting post, or at least try to.

This is just a test setup I threw together so please excuse all violations,  ideally you'd need balancing to connect them up in this way, also some proper earthing, fuses and oh yes, not a pile of wood next to an open inverter XD.

It's interesting to try analyse what you see here but yeah, clearly there are dry cells and i presume sulfation for the hot spots, you can also see the electrolyte levels in some. The bank was in daily cycling use but i doubt it saw any real deep cycles (due to the setup). It was set for a daily equalization charge and too high of a float voltage so ultimately gassing killed it. But hey 8 years is still respectable for a semi deep cycle.

Cheers

I wonder if this is not a service that one can render for checking battery banks?

And I am not above paying ... :)

What could it cost, and how do you handle sites all over the country?

Hah, thinking big already, I like it :)

But I recon costs would be quite high if you got some certified bloke to check your system. Me of course not having said certifications thinks its unnecessary :D 

Honestly though, i've ran some ads a while back and had zero interest, so i can only assume people don't know what it can do for them, maybe think of it as a gimmick.

I think anyone's best bet is to get a flir one for your phone and charge your friends in beers. Speaking of which if anyone on the forum would like, id be happy to come over and lend it to you, provided of course you're not too far away. The price would be some beers and compulsory eskom smack talk.

cheers

Now let me guess ... even though I have the beers, you are too far away? :D

Checked the prices of the camera's ,,, eina!

Hey TTT, i can pop over sometime with my camera, if you cover transport costs.

Its not quite the same resolution as Weasel but still good at 240 by 180 (Fluke Ti27) and thermal sensitivity at 0.05 degrees C.

I also don't have any certification but it's fun to play around with.

Lekker spanner in the works, you all living elsewhere and not voting right!!! :D

BUT, another idea has now been planted ... busy germinating, from CPT. :P

Now to find a camera in CPT, with someone who wants to make the effort earning a few rands to screen batts so that we can learn and see if we can find problems this way, BEFORE the banks are destroyed.

I would imagine it may take a while to learn the caveats on what to do with the information presented, to then check regularly that the batts are now happy.

Hey Chris, i am going to take you up on that offer. :D

Hey TTT i am keen on screening batteries, maybe a joint venture?

Wonder if it is possible to scan PV panels for defects?

yep you can certainly check panels, its a bit tricky with the emissivity and reflectivity of glass so its better to check them on the back which is of course a problem once they've been mounted.

Panels and batts ... what do you propose for a JV for I have 2 people in mind that can maybe handle it in CPT, being either in solar industry OR supplying batteries. 

The camera's ... that is a costly problem, not?

Why do you not have a chat to solar installers, and do that as a service to THEM, and they to their clients?

I chatted to two solar companies / installers and they did not seem to think that the client would want to pay the extra costs. 

Needless to say i am not the best at marketing myself.

Also the training is very expensive at about R20 000 / level (3 levels available in Jhb nothing in CT)

That's interesting thanks. Will have to investigate further.

The cameras are quite expensive, but the phone attachment (FLIR One) goes for about R5000 - 640 x 480 and 0.1°C resolution.  I'm just waiting for supported device confirmation...

You can buy another Axpert for that price. :P
