Has anyone sourced or used alternative CTs of same specification to those supplied with VM-3P75CT energy meter successfully? The 10mm diameter is fine for smaller cables e.g. 16mm2, but for larger 25mm2 or 35mm2 a 16mm or 24mm frame size CT would be great. I would suspect they exist but there isn’t…

This is the used CT: https://nl.mouser.com/nl/ProductDetail/KEMET/C-CT-0810?qs=doiCPypUmgFbdNX%252Bmy9Z2Q%3D%3D It’s mentioned in the manual: 3.1. Installing and wiring the split-core current transformers - 3. Installation Note the following when installing the split-core current tran…

@M_Lange thanks for sharing this information. I didn’t spot that link! From the Kemet datasheet the specs are provided. [Screenshot_20260713-161345] It does seem challenging to find a similar alternative with bigger diameter. However I see in the same Kemet model range a 120A CT is available wit…

For your application there is a new version: the VM-3P5A. Basically the same meter with a generic CT input. Any CT that has a nominal secondary current of 5A is applicable (and that is a big pool!). In the setting you can set the primary current. The news has been out since about 2 months. I’m not …

There was a news about the 3P5A? Can’t find it. No it still can’t be ordered.

I did know about it… but I can’t find anything in my old mails. It is mentioned in the blogpost about Intersolar on June 17th. And in May in a thread here.

Ah, ok so it’s this blog post. [image] Intersolar Europe 2026 - Victron Energy Come and meet us on stand B4.150 on June 23rd, 24th and 25th at Intersolar 2026 – the world’s leading exhibition for the solar industry which takes place in Munich. Ask questions and get hands-on with our reli…

I believe Victron originally suggested a release in Q1 of 2026. That’s clearly been and gone, so has Q2 so I’d imagine it’ll be pretty soon. regarding the kemet clamp, I’ve been using it for a while and it performs identically to the supplied clamp as far as I can tell. I do not exceed 80amps so ca…

My last information is July, so basically now, but it’s not in the Q3 price list and not in e-order for distributors. I guess there is another delay for a few weeks.

Yes the 5A CT Meter will be much better solution once it becomes available. For now it’s possible to work with the current VM3P75CT. Larger 120A CT has arrived. Some photos for size comparison; [PXL_20260723_155134242~2] [PXL_20260723_155149933~2] Unusual that the direction K>L appears reverse…

Continuing the discussion from Victron VM-3P75CT Energy Meter Alternative CTs Larger Frame : The tech specs and the manual state that for that model it is rated for 75A 80A max. Thata pretty official statement as the the device limits. What more is needed? 2.1. Features - 2. Introduction …

There will be a new VM-3P5A soon that supports all standard CT with 5A.
