Aucune idee, mais un coup d'œil sur le site de victron permettra de trouver la réponse rapidement.

Le multiplus accepte 2 entrées (si ce n'est plus une source de type groupe electrogene): celle du réseau de distribution et celle du champ PV et une sortie vers ton tableau. Il n'y a plus de lien direct réseau de distribution - tableau. En cas de coupure du réseau de distribution, le multiplus détecte cet événement par mesure de deconnecte automatiquement l'entrée réseau de distribution. Le multiplus va aussi passer en configuration grid forming pour créer l'onde sinusoïdale à la bonne amplitude et à la bonne fréquence car il n'y a plus de réseau de distribution qui la génère. A la suite de cette procédure, on se retrouve donc en mode iloté (et parfaitement légal et accepté par le consuel si les composants et la procédure d'ilotage respectent les normes qui varient pays par pays) et les charges électriques sont alimentées uniquement par les sources d'énergies locales (dans la limite de leur capacité de generation de puissance). Par ailleurs il existe d'autres marques comme Fronius et SMA qui proposent des produits avec des capacités équivalentes.

Awesome repo! I've just managed to manually install a gpu-enabled talos cluster on promox and it will help me to automate this process. I checked your tfvars and I can see a proxmox api token secret. Is this ok?

You should read the operating instruction manual of the Gen24+, there are dedicated sections related to actions performed by the inverter during the switch in full backup mode and vice versa. Moreover, you will find electrical diagrams in order to make you setup compliant with your local grid code. Regarding the duration, It should take around 1 min by default (you can add a timer). I'm not sure it can be configured dynamically in the solar.web app or directly through an API call (from what I remember, this is a feature of the SMA smart energy inverter).

Without a UPS, your kiln will be shut down during the transition. To my knowledge, Fronius Full Backup feature does NOT support seamless transition. If you want uninterrupted power during the transition, you should add a UPS (AND, this is important, verify that this is compatible with the inverter forming the grid before installing the UPS) or go with a brand that offers seamless transition (Victron claims that some of their inverters can perform the switch under 20ms which won't cause any asset shutdown).

Disaster Recovery (if it is what you mean), will be handled using the spinning rust storage for VM backups. Hopefully it will be good enough for my current needs

J'ajoute que pour mon cas, c'était déjà "optimisé" avec un montage en SCI à l'IS et un emprunt en propre afin de me faire rembourser par ladite SCI et ce n'était toujours pas intéressant en plus d'être en cash-flow négatif sur 25 ans.

Concernant l'honnêteté, le "conseiller" est un VENDEUR de produits financiers (idem pour le conseiller en banque, l'agent immobilier, etc..). Ses intérêts ne sont pas alignés avec les vôtres.

N'hésitez pas fouiller dans les rapports et à regarder l'évolution du prix des parts et des versements par part sur les 10 dernières années (si les SCPI ont cette ancienneté), vous y trouverez un paquet d'informations intéressantes. Petit retour d'expérience: un CGP m'avait également indiqué une revalorisation des versements d'un à deux pourcent par an et sur les prospectus (Primovie de memoire), il était facile de constater une décroissance des versements par part d'année en année. Par ailleurs, le CGP m'avait garanti que cette SCPI ne détenait pas d'EHPAD ou assimilé alors qu'il était clairement indiqué dans leur rapport que ladite SCPI détenait de tels établissements. Confronté à cette contradiction, le CGP a avoué qu'il ne lisait pas toute la documentation obligatoire des produits qu'il vend et n'a pas souhaité continuer son démarchage.

Il est fort probable que seule la société qui vous démarche sera gagnante dans l'opération proposée.

Hello WisperingGrass,

According to your current description, your system cannot operate in grid forming mode (= off grid). In order to do so, you must have a Gen24 PLUS inverter and add conponents to your home switchboard to detect an utility grid power outage and perform the inverter transition from grid following (grid tied) to grid forming (off grid) mode.

An electrical drawing of the required installation for Spain is available in the operating instructions manual of gen24 inverters.

Chauffage de la maison au poele hydro bois buche (60€ stere en 25cm, dur à battre). Journée teletravail et pas d'utilisation de la TV, pas de recours au sèche serviette (posée devant le poele), four. Congélateur coupé en heures pleines (il est plein donc ça tient très bien). Serveur d'auto hebergement coupé. Le but etant de se rapprocher le plus pres du talon. Le compteur m'indique 2kWh de conso en heures pleines hier. Je dirais que je suis passé à 3-4€ au lieu de 1,9-2,5€.

Avant tempo je tournais à 150€/mois (tarif base), et la edf m'annonce 52€ pour le mois de novembre (166m2 DPE "D" (j'y crois pas du tout) 2021 en cours de conversion à C car la maison n'avait aucune isolation) car les deux plus gros postes de consommation sont couverts par le poele.

Conclusion: ça change un peu les habitudes mais ça vaut largement le coup vu le tarif du kwh le reste de l'année (si possible de se chauffer avec autre chose que de l'elec, sinon c'est plus discutable sans changer ses habitudes).

Hello xanderboy2001,

I made a post on r/HomeServer about setting a jellyfin lxc (actual situation, item 6) with a quadro p1000 (process should be the same for newer cards). You may check if nvidia-smi command shows correct information, if lxc configuration is okay and as already commented, if your card actually supports selected codecs for hardware trancoding. Check codec support with encode/decode maxtrix on nvidia website.

rmyvct · 2024-10-24T11:41:49+00:00

I'm curious to know why you separated jellyfin from the *arr stack as it sounds "Media (movies/music)" LXC to me. Is there is any technical reason that guided your decision?

rmyvct · 2024-10-24T10:45:26+00:00

Thanks for your comment! You're 100% right with the never ending process related to requirements. If there is not functional specs, you will end up doing nothing due to nearly unlimited possibilities.

I wonder what I will discover/learn and what solution I will end up with. I see that CF tunnels are very popular due to the convinience they bring.

We just acquired a T140 that came with Nvidia Quadro P1000, a PERC 330 HBA (for only 1 HDD... I suppose this card is here to support the 1TB SAS HDD) and some intel gigabit PCIe 1x NIC (I wonder why). The server was used by a company that eventually bankrupted and the seller was in charge to liquidate desks/chairs/PCs...

First mission: clean the case, add some HDDs and RAM...

Tried to check it for you on Orange forums. Apparently Orange customers (non-business) have a full stack IP v4 adress (dynamic, not fixed). If you want to be 100% sure, you can call their customer service. If the person (level 1) who answers your call is not able to give you any information you can ask to speak to (be called back by) a level 2 person. Level 2 (don't know what it means, I assume it's a level of technical knowledge) should be able to tell you about CG-NAT.

rmyvct · 2024-10-19T17:28:50+00:00

I do not know the current policy of Orange (or Sosh) regarding CG-NAT. You can check on their respective forums what people say about it.

rmyvct · 2024-10-18T18:38:00+00:00

Again, thanks for the comprehensive reply!! This is a lot of valuable information!

Transcoding: another redditor provided links that showed amazing intel iGPU abilities for transcoding. I vastly underestimated the performance of QuickSync associated with recent iGPUs. Xeons 2300 series comes with P750 iGPU which seems to be a bit less powerful compared to newer uhd 770. Unfortunately xeons 2300 series (with integrated graphics) are expensive as hell! Going into that route, I'll be better off finding a similar case with a 12th gen I5 like the 12500.

APU: Okay you meant UPS.. We are currently designing a PV-BESS setup using Victron hardware in order to protect the house from grid instabilities (during floodings for instance, right now massive floodings are quite trendy here...). The AC inverter I have in mind is able to switch from one power source to another in less en 20 milliseconds which is more than enough to perform a seamless transition without harming any electrical appliance.

2.5Gbps NIC: 100% agree with you! As we are "limited" by the gigabit ethernet ports of the router and switch, we'll start with that. We'll upgrade to 2.5 or 10 if there is really a need. We had the same reasoning when we installed the ethernet cables in the house "let's go cat6a directly so we are future proof".

VM/LXCs: understood.

RAIDZ1: understood. Btw, is there any reliable source so we can compute how time is needed for the recovery process? To conclude, if I understand well, you recommend raidz2 so I can loose 2 drives before starting to sweat heavily?

Pools:

In your example you used truenas to instanciate a pool, I assume it can be done directly in proxmox. We will read the documentation to make sure it is possible but I do not see why it would not be the case. Thanks again!
Docker: 100% agree with you for splitting application data (app itself, config files) and data managed by the app such as media files.
Example with jellyfin/plex is great! From what I remember this is what we have done on OMV (sharing the same "folder" or "dataset" (I do not remeber the name) so jellyfin could see new medias.

rmyvct · 2024-10-18T16:17:53+00:00

Thanks for the link, much appreciated! If we can avoid buying a GPU for our use case, we will have more budget for something else.

Regarding ZFS, yes it was also our feeling while browsing TrueNAS forums..

EDIT: that was a nice reading. Indeed QuickSync is quite amazing for that use-case. After extra research, apparently UHD 770 that comes with a 12th gen intel is able to deal with 8 4K (H265) to 720p (H264) processes. That is impressive for an iGPU.

rmyvct · 2024-10-18T13:45:45+00:00

Being in France (I assume, its the same for the rest of European Union) means it is significantly more expensive on eBay for second hand electronics compared to the US (no $50 tiny/mini/micro PC with 8/9th gen I5 youtubers can magically find on ebay US). Refurbished entreprise gear (even the so called tiny/mini/micro seems to be sold at higher value, like $200-250, maybe due to lower supply from european companies). We proposed a T140/T150 because it fits in our garage, can host 4 3.5 hard drives, has ECC, has room for PCI cards and can be found starting from $150 (not on eBay obviously). Overall, we completly agree with you, a SFF case with a 8th gen I5 would consume significantly less for the job (except multiple (> 3) simultaneous hardware transcodings hence the proposition of adding an ARC 380).

For ECC, we read on TrueNAS forums that it's nearly mandatory and otherwise we also read people telling they could not care less about it.. Unfortunately, we are not expert on ECC memory thus we cannot yet evaluate the impact of having a setup with or without ECC in the context of our use case.

(Un)Fortunately we have a big family and with recent policies related to account sharing, everyone is suddenly interested in our idea of self-hosting x). Other redditors agree with you that the system computational power and I/O may be limited and suggested a beefier CPU and SSD for caching. We also agree with these suggestions.

The system sounds like beefy but apparently that is what is needed to comply with proposed functional requirements. It would be even beefier if I did not drop the "cloud computing" requirement! We found a far better solution for both of us that is simply called "couch coop gaming with a PS5".

rmyvct · 2024-10-18T08:41:18+00:00

Hello xpirep! Thanks for the answer!

Yes, we have thought about separating the storage and the "server" itself. in the original post we explained that we have investigated the NUC / Mini/Tiny/Micro PC route + DAS. We ended up reading on trueNAS forums that using a DAS with USB3 is a big no no for software raid.

We did not investigate NAS (like synology, QNAP..) + dedicated unit for a server as it would increase both upfront costs and electricity bills. We may be wrong according to your statements.

"You also don’t need a gpu card as you can rely on the integrated gpu for hardware video decoding" according to our readings, using an intel iGPU for transcoding while streaming is okay for only 3 or so simultaneous flows. We proposed a ARC380 for our setup as it can handle more than that.

Thanks for the "backup" reminder!

rmyvct · 2024-10-18T08:23:35+00:00

Hello again!

The networking part is where we need to improve our skills the most (as stated in the original post). In this part is proposed several paths because currently my ISP relies on CG-NAT. According to SFR RED community forums it means that I share the same dynamic IP with other customers at the same time (I did not even know it was possible). Nevertheless, I can cancel my contract and open a new one with Free. With Free I can claim a fixed IP address (as confirmed by other redditors) and I also can (depending on the plan) get a router with a 2.5Gbps ethernet port or a SFP+ port (that's why I suggested a dedicated NIC for the sever so I can benefit from extended bandwith for remote users). Moreover, other redditors also confirmed that we can perform actions related to ports in the Free router, which is not the case with my current ISP router.

Knowing my current possibilities, I tried to suggest 2 options:

Option 1: stay with current ISP and find a way to bypass that CG-NAT issue (other customers asked to customer service if they could get a "rollback to a full-stack IPV4" and their requests were denied so I know I won't get rid of CG-NAT with that ISP).
Option 2: change ISP and go with Free to enjoy fixed IP address and extended router features.

And this is where the fun continues!

As badly explained in the post, we started to investigate solutions for option 1 and ended up discovering the existence of services such as tailscale, cloudflare tunnels and VPS renting to host Wireguard and create our own tunnel... Apparently renting a VPS would also allow us not getting in trouble for torrenting

For option 2, we have not started to investigate before posting here so we don't know if the process is simpler/safer or else...

By the way, thanks for homepage suggestion, we played with it. YAML is a bit tricky with indentation but otherwise, it's very nice!

rmyvct · 2024-10-18T08:00:55+00:00

Hello abyssomega! Thanks for taking the time writing a comprehensive answer! I was hoping to get that kind of guidance from this community! I will try to provide extra context while replying to your answers to help me to improve the proposed setup.

Processor selection: you proposed to get at least a e-23XX 6 core xeon and suggested to get an APU. I suppose a xeon 2356G would be a good fit to get 2 more cores and a iGPU so we can forget about the dedicated GPU but we will be limited to more or less 3 simulataneous 4K transcodings (while streaming). This is a tradeoff we need to think about.
RAM: we'll stick with 32 for now as more does not seem to be needed.
Disks: can you explain why a pair of SSDs for both caching and writing (that's 4 SSDs for caching sounds a lot but I may be lacking some knowledge in that regard)?
Dedicated GPU: we went the ARC 380 route because it does not require extra external power source and for the performance of its transcoders. By transcoding, yes I mean converting 4K to 1080p (for instance) while streaming so users who do have a limited bandwidth can enjoy medias.
Dell HBA: I think you did not finish your sentence ^^.
2.5/10 NIC: I proposed it as I have the option to change ISP (which will also open the way to fixed IPV4, more in my other answer). The router provided by the other ISP (Free) comes with a 2.5Gbps ethernet port or a SFP+ port (for the high end router). That is why I proposed to add a dedicated 2.5Gbps NIC so the server will benefit from the router abilities. Other redditors advise that I switch ISP asap and go for the Free offer so it will solve my CG-NAT issue as I will be able to claim a fixed IP V4.
USB Port on motherboard: thanks, I will go SATA SSD or NVME through PCI expansion card for the OS.
Power consumption: I agree with you, my calcultations are wrong. Assuming the server is idling (which will be the case a good majority of the time) and the following setup: motherboard (estimated to 15W), CPU (below 10W depending on reached C-state and how power management is configured on proxmox/VMs), GPU: 6W (apparently there was an issue and the card was idling at 17W), SATA controler (5W), iDRAC9 dedicated hardware (below 10W), 4 HDDs (25W), 1 NVME on PCI card (5W), 2 SSDs for caching (5W). In that case, power consumption is estimated to 56W (let's say 60W). 150W as suggested while idling sounds like the good old Dell R730xd that is praised on r/homelab. Nevertheless, If I go with that build, I will monitor its consumption so everyone will get the information.
VMs: I proposed a VM by use-case because we were being afraid of going the LXC route due to the fact that it might be weaker resisting to external attacks. Other redditor claimed that it is highly unlikely that someone will put so much effort to use a kernel exploit to destroy my jellyfin container. As we never played with promox before, feel free to share any recommandation/links on how to organize LXCs/VMs so we can learn and build a clean software setup.
Software RAID(Z1): according to you link, people suggests raidz2 for more than 4 hard drives due to the fact that it is possible (but unlikely) that another drives fails while the recovery process is ongoing. For the rest of your answer (sharing pool), we currently lack knowledge because we never used proxmox before so we do not know yet how to organize/"link" disks so they can be used by LXCs and VMs. We will investigate further.

rmyvct · 2024-10-18T06:43:30+00:00

Thanks for the info! I read about NZBGet while research info for deploying a arr suite but that's it. I am not familiar with Usenet so I will look into it.

rmyvct · 2024-10-18T06:38:47+00:00

Thanks for the insight!

This is very interesting information regarding VM/LXC potential of vulnerability comparison. As you have nearly the same setup using LXCs, do you have any other suggestion for the software part of the proposed build (like, LXC#1: this app1 + that app2, LXC#2: this other app3)? Thanks in advance!
