Currently have a PV system which we are upgrading. The current system contains the following
400 amp Main Service Panel (Square D SU3040D400CB - 200amp Main CB & 200amp CB Sub-Panel)
The Main CB was derated to 175amps when the PV was installed
The Main Service Panel (MSP) is back-fed via a dedicated Solar Meter, Disconnect Switch and 35 panels & Enphase Microinverters & Collector.
Both the Main Service Meter and Solar Meter are identical except for the seral number
In conjunction with the the upgrade, adding 30 panels & microinverters, the solar installer proposed to the Utility (TEP) to place a ConnectDER on the Main Meter Socket. They objected saying the DER is only rated for 200 amps and the meter is currently 400 amp service. So now the question -
Can the ConnectDER be placed on the Solar Meter? This way it is on the 200 amp side of the MSP and would never see more than 200amps.
Here is a link the the MSP (https://www.se.com/us/en/product/SU...aces-40-circuits-25ka-sccr-320-manual-bypass/)
So what's the opinion, can the ConnectDER be installed onto the Solar Meter? Are there any references I can site to the utility and/or installer?
Thanks, BB
