Hi William,
Our metered Envoys in North America can only be used with the Enphase 200A consumption CTs (CT-200-SPLIT). Many of the off-the-shelf CT options have an embedded burden resistor and output millivolts. Our CTs output milliAmps and we have embedded the burden resistor on the Envoy board. Unfortunately, you won't find an alternate CT.

I wish to monitor consumption. It appears to me that Enphase offers only one model of CT which may be a bit large for the space I have. The panel is only 100 Amps and thus has smaller feeder conductor than a 200 A would. Does anyone know if one can substitute other manufacturer’s CTs in an Enphase system? As always, thanks for any input. William Miller [Gradient Cap_mini] Lic 773985 millersolar.com<http://www.millersolar.com/> 805-438-5600
