I have the Solar Sense with the 2 pairs of CTs. I have a 400A safety switch where the Sense is installed like so: (The Sense CTs barely fit over the 350 MCM copper cables)
This is on the outside of my house. To the right of the switch is the utility meter, to the left is a 400A automatic transfer switch that feeds 2 200A sub-panels in the basement on the other side of the wall (and a 20kw Diesel generator is also connected to the transfer switch, but not at the time the photo was taken).
You can just make out the sense antenna sticking out the bottom of the safety switch. I have a detached shop building located 200 feet away, which contains a 3rd sub-panel, which includes 6 breakers for a 20kw micro-inverter based solar array (80 panels). Here it is:
The 6 20A breakers at the top are for the solar strings, and all the lower breakers are loads in my shop.
So what happens is that EVERYTHING that goes on in the shop sub-panel is going through the Sense solar CTs. So what happens is that anytime a device in the shop uses power, it gets subtracted from the solar total.
So would it be possible for sense to distinguish ingress vs. egress on the Solar CTs and not count the egress (loads in the shop) towards solar production, but instead treat them as loads just like everything I got hanging off the 2 sub-panels in the main building?
