How to disassemble the MPPT Victron?

I disassembled MPPT Victron in this way. I had to do repairs inside because there was a broken component

See They Made IT So Hard To Fix Thanks For The Video

I posted this video on Victron's Facebook group, it was not approved by the admin. LoL 😆😆

Merci beaucoup pour cette vidéo très instructive.
Mon MPPT 250/100 ne s'allumait plus. Je pensais que c'était les fusibles. Le hic c'est qu' ils sont à l'intérieur bien scellés!!! Pas très judicieux tout ça! Il fallait donc l'ouvrir.
Malheureusement en démontant le boîtier à coup de gros tournevis sur les bords, j'ai dû me résoudre à arracher du PCB, 4 bobines et 8 condensateurs (250V 330uf). Bon, ça se remplace et se ressoude sans problème.
Ce qui est sûr c'est qu'il est impossible de faire fondre ou même ramollir cette satanée résine.
Une fois déposé, j'ai pu desceller sans chauffer les 8 condensateurs HS et les 2 petites bobines à resouder; mais pas les deux grosses bobines centrales: je dois me résoudre à découper le boitier comme sur la vidéo pour ensuite les ressouder sur le PCB.
Pour la réparation je dois donc:
1. remplacer et souder les 8 condensateurs;
2. resouder les 2 grosses bobines centrales après découpe comme sur la vidéo;
3. resouder les 2 petites bobines sur les côtés;
4. remplacer les 2 fusibles de 70A qui étaient bien grillés (c'était la panne en fait!);
5. et il y a un MOSFET explosé à remplacer aussi (ce qui a fait sauter les fusibles je pense)
Bref je pense que ça vaut le coup de réparer ce contrôleur de charge au prix que ça coûte.
En espérant réussir la réparation.

Thanks!! IRF14321 mosfet. 14mOhm, 150V, isolated package for direct contact to a big shared heatsink. The 150V advertised limit has no wiggle-room whatsoever. If your solar panels go over 150V, these mosfets will work as zener diodes and heat-up and thus die quickly unless the firmware prevents it. Two buck-converters maybe, low-side having more mosfets. 4nF input per mosfet, 0.4nF output.

[@solusiHarisman]

Ya sincronous buck conveter

[@jirkas229]

i have lifetimemax on 150/100 154v and no problem :)

[@solusiHarisman]

Ok

It seems Victron are trying to be the Apple of solar power. Very repair unfriendly.

[@solusiHarisman]

Lol

[@andreassiebenmorgen2403]

Did you have the measurements of an mppt 250/100? I will try to open mine…

[@solusiHarisman]

I haven't had any repairs yet

[@Josemarquez-nu2sn]

This one brings two toroids, disabling one toroid will keep it working. I have a Victron and I also burned a MOSFET and the Toroidal coil. can you help me

[@solusiHarisman]

But the power a half

[@Josemarquez-nu2sn]

@@solusiHarisman I understand if I disable one of the torodes I get half, my mppt is 250/100, that is, it will only work at 50 amps. I find it difficult to fix the toroidal suffered a big burn, let it work like this while I fix the other toroidal. rewind the toridal that you recommend my friend. thank you. for his answer.

[@solusiHarisman]

Toroid is 70 uH

[@romanmorozov4520]

Can you try to warm up this gel? Maybe it was worth reheating the case for some time in the oven and the lid would be removed?

[@solusiHarisman]

Please try. if successful report here please

[@romanmorozov4520]

@@solusiHarisman Unfortunately, my victron is waiting for a decision from the victron supplier, they don’t even want to check what’s wrong with it yet, it always shows a low voltage at the input of the panels after only 4 months of operation, and all three lights sometimes flash 8 times. I don't dare open it, but if you have leftovers from your Victron, you can try heating the gel to different temperatures, 100, 200, 300 degrees, and see what temperature it softens. Perhaps some temperature barrier needs to be overcome.

[@solusiHarisman]

@@romanmorozov4520 the gel is made of heat-resistant epoxy. Bind the capacitor and inductor windings. We know the heat resistance of the capacitor is only 125 degrees Celsius. So it's not possible to be heated above 125

[@romanmorozov4520]

@@solusiHarisman In that case, we can say that Victron are inhuman assholes who sell their controllers at 5-10 times their cost, while making them unrepairable. If I had known they were doing this, I never would have bought their controller. It's better to avoid such scoundrels.

[@andreassiebenmorgen2403]

@@solusiHarisman maybe you can sacrifice the capacitors instead of the housing, and replace them after heating the expoxy to open it?

Do not buy those solar converters, simple...

Bonjour je souhaite avoir votre contact pour une réparation si possible merci ?

[@matthiasjoseph]

How do you know where the coils are? Surely they have different locations on each model..

[@solusiHarisman]

clearly between the coil and the capacitor above there is an empty. Cut it first so that the position of the coil can be seen for different types

Very low grade workmanship. I use low temp heat gun on front face for approx 5 minutes , screw the base to a work bench and lever off gently, use more heat if needed. All you have done is completely wreck the unit. Not a job for home handyman of apprentice.
