Carlo Gavazzi requirement: 3 phase, individual phase balancing OVER 100Amps - has anyone done this?

Hi Victron Genius's! I am in New Zealand where the revenue metering is done on a PER PHASE basis - not like the rest of the world which seems to be Net Metering.

For ESS installations below 63A we install the ET340 and the system runs along nicely.


However Lately we are getting mor enquiries for larger commercial systems where the mains are over the 63A limit and often over 100A per phase...


QUESTION: Is there a Carlo Gavazzi metering solution we can use?


Or do we have to try to extend the CTs.. and put up with a 100 A limit on the 100A:5mA CTs..?

Hi,


you use a Carlo Gavazzi meter with separate CT's, these you have to buy locally as Victron doesn't have them in stock.

“the EM24DINAV53DISX, which uses Current Transformers and can therefore work in systems > 63A per phase, has been tested and works. Note that this model is not stocked by Victron Energy, we recommend to purchase it locally.”
