ESS Meter for 120/240V Split Phase - ET340 AV5 or AV2?

Need a quick sanity check on the version of ET340 that supports US split phase (120v/240v).

Victron manual states that the following version is supported & for sale through them: EM24DINAV53DISX

When you look at the actual Carlo spec sheet the voltage ranges do not line up for split phase market.

AV5: 400VLL AC - 1/5 (10)A (CT connection) VLN : 160 V to 480VLN VLL : 277 V to 830VLL

AV2: 400VLLAC 10(65)A (direct connection) VLN : 113V to 265VLN VLL : 196V to 460VLL

I believe for split phase AV2 is needed - spec. sheet (linked to a reseller since the manufacture site is tough to navigate)

Accurate or am I misreading the sheet?

In addition I can find the AV5 for sale but not AV2 and I would need to use a CT sensor and AV2 appear to only support a shunt.

Anyone using the ET340 successfully in a 120/240V setup and measuring up to 65amps? If so what version and what is your setup?

Thanks

I think you would need AV2. Contact Carlo Gavazii sales support, they were very helpful for me. They can assist with placing your order as well if you are having trouble finding this model elsewhere.
