I was thinking rather that you put them in "native", that would save you from this double comment we are going to say a little "laborious" for you and also for the person watching.

[Remundo]

ah ah ah, I'm glad I helped you I'll know for next time!

It's not a kit but it's DIY:

Currently 5 405Wp panels on Hoymiles HM800 microinverters and Open-DTU gateway (also DIY)
Support placed on the ground DIY manufacturing also from recovered scrap metal.
I still have 4 panels to install to ultimately have 3.6KWp and hope to be able to charge the car "for free". I have already done my first "solar" kilometer but it is not with the current weather that I could do a 100% solar charge.

My immediate problem is managing the injection into the network. For the moment no consuel or CACSI (it's in progress) so I'm trying to manage not to inject anything onto the network. It's a little script on my home automation system which manages the production limit of the inverters, but there are some gaps...
I'm trying to do this under NodeRED to have a more responsive system, but it's a hassle, I know nothing about this "language", if there are any professionals in this environment in the area I would like a helping hand.

buy yourself a hybrid inverter, some have functions so as not to inject anything into the network, but use it if the batteries are empty.

For CACSI it's a mandatory administrative paper, which almost everyone doesn't care about... including Enedis.

I don't know how your inverters work in the event of a network outage... I have a friend who works in an intervention team at Enedis, he is increasingly confronted with tensions present on networks that are theoretically more powered.. Despite the fact that there is no production installation declared on the said network...Now they are no longer laughing and no longer wasting time...Earthing and short circuiting of the three phases... He says that sometimes it's serious...

[Remundo]

All serious injection inverters comply with the “DIN VDE” standard and stop if they lose the network phase.

It is possible that some perlinquinquins use "things" ("Chinese" injection inverters or inverters for isolated sites) which push electrons all the time as long as they have PV to power them.

This is why the certificate of conformity to the DIN VDE standard to which you refer must be provided with the CACSI application.

On my installation it is Hoymiles HM800 microinverters which comply with EN 50549-1:2019, DIN VDE V 0124-100:2020 and DIN VDE V 0126-1-1/A1 VFR2019 ERDF/Enedis-NOI-RES_13E: 2018-12
No worries, they shut off well in the event of a network loss.

Then there are other brands of microinverters, one in particular which is quite fashionable, which normally requires an additional decoupling box to ensure cut-off in the event of network losses. Not sure that all Sunday DIYers bother to buy the decoupling box...

Mmmmmmm... Now?...

It seems to me that grounding (to protect against "wild" production) does not date from today...

I've been self-consuming (or self-producing) for more than eleven years and I've been hearing about this problem (and this practice) for several years now.
