I agree in transport applications it's important and the heating hack makes all the difference, cheers

Yes, we will get round removing the board, busy time of year on a small holding, cheers

Exactly, driven by corporate strategies to drive profit, cheers

Yes, KZfaq search leaves plenty to be desired, maybe next time. I experiment so that you don't need to. Please subscribe, cheers

Thanks for your thoughts Jason, hope you;re a subscriber, cheers

Hi, I knew the unit was duff, especially as the 80A fuse was blown. Yes a limited current supply would have prevented the blue smoke dragon. The main part was removing the top with a hot air gun. cheers

@@TheInfoworks Look for "RIDEN Power supply" They are cheap and fantastic things with lots of decimals, current limit etc. Easy to power directly from 12V or 24V battery. Makes it isolated and portable. I have the RD6018 RD606 and tiny RK6006. The RD6006 is the best for electronics with 4 decimals current reading.

Thanks for the comment, yes the video is to share the info and help promote self reliance, cheers

Hi, that's grand news and if you apply the second rule of solar then they will last for years, cheers

Thanks for sharing your experience, many people have recommended Epever. My Old Victron multiplus just keeps chugging away, but we never stress it. Applying rule 2 of solar, cheers

That's tough, I teach, check the polarity, mark it with tape, then check it again. Never imagine it's right, cheers

Did the same to one of mine. You'd think it would have polarity protection like cheaper ones

Interesting the smoke came from one side, we will be looking in good time. We run a 48v system so there is no rush, cheers

having seen inside this could be possible but what would it do to the varnish on the coils?

@@TheInfoworks the prop’ alc’ and your question just gave me a nudge to times past re: sterilising electronic gear, ( don’t ask🫢). As I remember aftEr much experiment we used formalin and pure alcohol ( customs licensed - >70%) and sprayed very fine mist/ fog. The normal formaldehyde which is quite vicious in its own right was not the problem on circuit boards but the minute drops of liquid ( with the higher water content ) keeping the minute junctions wet long enough to corrode , just thinking out loud 🌝

@@TheInfoworks stratgic displacement of the ipa is the key. Pouring ipa into the enclosure is obviously not recommended. A syringe much like what medical people use

Hi, the melt test sounds a good idea, I going to try that with a heat gun. The problem with heat is the capacitors all packed together in potting. I doubt they would survive as the contact pins are not very strong. Keep watching, cheers

Hi, thanks for the comment, I'm thinking vibration proofing when in boats or vehicles, cheers

yy its gross weight this coils, or transformers, it helps for more mechanical robust and cooling too, disasembly is hard, i see open it for use heat for lid and then little bit strenght and it happens

Hi, I seem to get on well with Steca units, especially the Tarom series, cheers

Interesting, yours are obviously early models, this is definitely plastic and this is probably why the heat method worked, cheers

I notice that all the screws have a dab of glue, but the potting is rather excessive. I sort of understand the reasoning, but there must be a better way, cheers

Please tell me more if you would, im about to go in on mine. I've got the BlueSolar 100-50 that has an aluminum cover instead of a plastic one.

Thanks for your thoughts, yes it's not normally just one component and so greater knowledge is required, cheers

Hi, this came to me in an interesting pile of "bits". I understand the anti vibration but actually using it to glue the top on is difficult to justify, cheers

@@TheInfoworks Gluing to the top makes perfect sense, since the components are heavy, they need some thing to react against to keep them from vibrating. Very few people are capable of repairing DC/DC converters, maybe replacing FETs but when they go usually they are not all that fails. But without schematics its even harder. But a better mechanical design could have been done, but that would add cost and complexity, every consumer wants the lowest price and to by it on sale. On the other hand if they did not want you to take it apart why did they put screws in it? As I said not knowing the history of the MMPT who knows how it was abused, over voltage, over current, over temp, not grounded properly or factory defect, who knows.

@@TheInfoworks Agree. Making it unserviceable with "glue" is a crime. I think it is to save the coil from heating, but I would rather have a fan than a device filled with glue.

@@universeisundernoobligatio3283 They could be glued to the board. I think it is to get rid of heat from the coils and the capacitors as they offer quite high current for extreme users. But it makes the device impossible to service.

@@tofo2 The potting does not need to be so robust, the 100 - 50 came apart with no damage. The should be a better way to prevent coil vibration. I'm working on removing the cover on a 250 - 70, video soon, cheers

Yep, well get there, cheers

hi, I fixed this controller in a later video, cheers

Hi, at least it did come apart, but damage could occur. as you will see I've fixed another of these after a successful cover removal, cheers

Sometimes you just have to experiment to move forward, cheers

Brilliant, thanks

It's also noteworthy that while other Victron equipment uses a 8p8c connector it't not Ethernet (the protocol used for computer networks). They have VE.Bus (which I think is RS-485) and VE.Can. The VE.Direct port is a standard UART connection. This is known because if you look up "Victron Energy open source" they have actually release quite a lot of information about all of their protocols to the public.

Hi, welcome, I wouldn't pay money for it as there is commonly a cascade effect to component failure, meaning that it's not a single component. If you are an electronics wizard then maybe entertain it, but otherwise be careful and have no expectations of fixing it, cheers

@@TheInfoworks great advice! I'm sure they overpowered the solar input but who knows these days

@@TheInfoworks also wanted to say cheers on the pottery! Do you show vids of that as well? I'm introducing my kids to throwing and am looking for the right clay! I thought my soil would suffice but it's not right so we went to the closest store and bought the only one they sold but it's still not what we need

Yes, there's a whole playlist on my pottery adventures (ceramics) otherwise check out Andy Wards ancient pottery, cheers @@Laurel-Crowned

Hi, those 150/ 100 are impossible to take apart without major damage, so unless it's a software issue then I'm not hopeful, video on the opening up soon, cheers

Oh yes, but from the inside, cheers

Am building a large bank of recovered auto batteries for storage and to sell as a side business. Charging from solar at 48v and want to try your light bulb trickle charging method on my 12v battery recovery system. Having good results with pulse desulfation devices and 2 amp charger but would like to go direct from 48 v without electronics. Any suggestions from you or the viewers will be appreciated as this a work in progress . I am aware that auto batteries are not suited for deep discharge so I am building a large capacity so as to use less than 25 percent of capacity. These batteries have been purchased for scrap price so when they are used up they can go to be recycled and money spent will be recovered. Thanks for all you do.

@@teddycunningham7568 Good man, thinking sideways, no point deep cycling batteries as you just have to charge them up. Apply the first rule of solar and you will be on the right side, cheers

@@teddycunningham7568 any experience with glass mat or gel types ?

@@pollywollydo Forget gel, but AGM are fine if used as buffers and not deep cycled. If you deep cycle the life is about 4 years, cheers

@@pollywollydo the a.g.m. and gell are responding well to pulse desulfation device with trickle charging . Am buying scrap batteries any that do not have 12v after charging overnight are traded to my local auto parts store core pile where I only take home batteries holding 11.5 v or more . I often bring home 4 to 8 and have about 80 percent sucess rate after a week of trickle charging with desulfator.. working towards a bank of 100 or more batteries at 48v and a smaller 12v bank to process new arrivals.

Cheers

Hi. I agree with you that full potting would be a disaster, also form the previous comments there is a vibration dampening benefit for controllers used in trucks etc. Is this the best compromise, maybe not, cheers

That does it.

I hear it will, but what will it do to capacitors and the like? This seems to work and that I did not care if it turned out total destruction, cheers

@@TheInfoworks was thinking more of a few bleed holes in the case and flood with a few cc’s of acetone merely to release the “ lid” it’s going to be a type of technology which is going to be needed down the line with Tesla type battery repairs 🌝

Hi, do you think it needs one in this situation, interesting, cheers

just think for a momentif you would be comfortable joining the wires together for a dead short - if you are comfortable with this level of power in the wires, and any additional damage to the circuit, no need for a fuse - if not, you can limit any additional board damage or melted wire insulation by the addition of a fuse. I know this is a low risk, but, for something different imagine the recent japanese earthquake, or some other distracting emergency event (heart attack?) resulting in the pair of unfused wires remainig connected. (yes I know low risk ...)

John, it's an experimental dab, not a screw connection @@johnallen3555

Hi, this was a good led which FET could have failed, see the next video, cheers

Maybe, or as another viewer pointed out, it's an anti vibration feature when these units are fitted in trucks and boats. Still at least we know now how to get around it, cheers
