Installation help; two parallel main panels

installation

#1

I have single phase 200 amp service with two parallel main panels. I want the Senses CT sensors around the wires that feed both panels; Rather than purchasing a second Sense unit.

The fed wires disappear into conduits at the bottom corners of panels ( see picture ) and lead to the meter. Good news is that right behind the panels on the exterior wall is the meter ( see picture), but it’s sealed and I need the utility to come and open it and place the senses CT sensors around the feeding phases.

Can the sense be installed this way?

The Sense uses 240v. Does that voltage need to come from the panel the CT sensors are installed in? Because that will be an issue for me. Being that I have to parallel panels.

Have any of you dealt with this setup at your home?

Have any of you dealt with this setup at your home? How is it working for you?

Anyone?

No idea, but I don’t see why wouldn’t work. You will be putting the CTs on after the meter, correct?


#4

Yes just after the meter; just before the two service mains split into the breaker panels

Which neutral bar will you tie the Sense meter to?

Which neutral bar will you tie the Sense meter to?.. I didn’t think about that. I guess whichever panel i decide to pull the 240 from.

So I called the utility Co and they said it will cost over $400 to have them come out and do a disconnect at the transformer and then open my meter to put the CT sensors around the mains. What a joke. I’m pissed.

Looks like I have to purchase a second Sense unit.

Yup - way cheaper!

So, using two Sense accounts. I’m gonna have to log out of one and log into the other to get data. And of course get push notifications from whatever account I’m logged into at the moment.

Does anyone know how long it will be till two Sense monitors can be joined under one account?

I ordered my second monitor this morning. I hope the Sense team is working on the ability to join two or more monitors under one account.

@jmbetcourt, unfortunately I don’t have a specific timeline for multi-monitor functionality quite yet but it is something that we plan to tackle in the new year.


#11

Really enjoying having double sense monitors installed. Can barely wait for the ability to joint them both under one account.

I didn’t realize I had Parallel Pannels until I went to install sense. Lucky for me the split to the boxes was in a box below my two pannels. So I installed a breaker and the sense in one of the boxes, and put the clamps on the main lines coming in before they split to the boxes. Everything seems to be working fine.

I can see a change when I turn stuff on and off from both boxes.
