Compatibility with a hybrid inverter?

[poldim]

I currently considering putting in a hybrid inverter. Does anyone know where the best place to mount the CTs would be?
Any chance the solar CTs are able to read the DC from the panels if they are placed in position #4? Otherwise there is no way for sense to know how much solar was generated.

The post linked below may help you decide. As I understand it, there is no place to put the CTs that doesn’t miss something.

Multi-monitor and progress?

Your’re right - Panel2 has no way of knowing whether power is coming from grid or solar and the mix between them, So Panel2 stuff should be correct. The problem is that Panel1’s monitor has a fixed calculation to treat IPanel1 + Isolar as Itot1 (correct), and IPanel1 when negative as To Grid, and when Positive as From Grid (wrong). The real from and to grid needs to be done by combining Ipanel1 and Ipanel2. [Screenshot 2024-05-13 at 1.11.47 PM] ps: I finally drew out the setup and there are r…

With a battery, you add at least one more current flow in and out of the system. Sense is only really built for two current flows (x 2 legs) so you’ll never be able to see everything happening in a battery system w solar.

CT’s can not read DC current ,so that location isn’t possible.

Good point - the energy flow inside a hybrid inverter is DC, to and from the battery.

Thanks all, looks like I can’t use Sense for this system.
