For this Enphase equipment you can parallel another set of CTs to the same terminals on the Envoy/Gateway. Measure the other 200A breaker with the additional CTs.

Thank you for the information , would the CTs installed on the line side of the 200 amp breaker measure correctly ? one set of parallel load off meter goes thru a short nipple into 400 amp panel and connect to 200 amp main breaker that feed the breaker busbar ,the busbar does have two lugs at the bottom ,all breakers spaces in panel are being utilized . The first set of CTs are installed on the load side of the 200 amp breaker that feed the 200 amp panel mounted beside 400 amp service, again Thank you .
