3 Phases system in South of France (30KVA)

Hello every body,

This is my last installation of a 3 phases system :

  • 3 MultiplusII 10KVA
  • 3 PowerIn Lynx
  • VM3P75CT
  • EVCS NS
  • 27 KWp 3 phases Enphase (existing installation since 5 years)
  • 2 LiFePo battery 15 Kwh

My tooling prototype to have a perfect alignment :

very nice !!!

Clean install!

Nice dc bus wiring. Just one question Patrick do you run the ac and dc in the same trunking?

Hello @AJM1 ,

The DC circuit don’t run in the same trunking of AC wiring. The DC wiring cross the AC wiring under the M+ at the battery connection only.

Can I ask what are the load disconnectors used?

Hello @kaarliskr ,

These are fuse switch disconnectors equipped with a gG 250VDC 250A fuse from DF electric :

switch disconnector :

fuse :

They have a high breaking capacity regarding the short-circuit intensity of a LifePo4 battery.

Best regards,
Patrick.

Thank you!

Thanks Patrick that is what i actually meant. The reason i asked as in our country the national standards prohibit even that cross over of dc in an ac trunking. We need to keep the ac trunking on the left and the batt and pv coming in from the right( standing in front of inverter) making our trunking system for installers much more complex. And if it should not be done that way a certificate of compliance wont be issued.

Your inatallation very neat indeed.
