Energy Meter 250A

Hardware

Hi,

Does anyone know oan energy meter for a 250A connection in Belgium that is compatible with Home Assistant?

I should have 2, 1 to measure the PV energy and 1 to measure the main fuse.

Thank you

Kenneth

How many phases? Each 250A or combined? :thinking: Still @230V territory? :face_with_monocle:

What wire thickness we are talking about (regarding fitting ct coil/clamp)? :thinking:

Any particular certifications/labels needed for your use case? :thinking:

So that means the device does not need measure reverse current - correct? :grey_question: :question:

Not sure what the fuse means because an energy meter doesn’t measure fuses :person_shrugging:
It’s probably the grid power/energy you want here, correct? How about reverse power/current in that case?

And what are the wishes regarding integration into HA? Cloud? Local? Wired? Wireless? :face_with_monocle:

Hi,

Thanks for your reply.

250A, 3phase, 400V

90mm2

No certifications or labels needed.

PV energy question: yes, indeed. I only want to measure how many kwh my pv installation generate.

Fuse: Yes, the grid power I want there. Also reverse power at that point. That is why I also want to know how many electricity my pv installation generate, so that I can calculatie how many kwh we use directly.

HA: cloud if possible, wired is ok.

For PV you could use Shelly 3EM pro.
250A grid power is little bit trickier. Often the actual distribution is done with lower amp rating like 100A, even if main fuses are 250A. You could have a look what size of breakers you have in your distribution panel
