question

Wrong setup in Energy meters or PV inverters in Device list? The listed position has to be consistent with the physical topology. A schematic would help...

thanks a lot, I will check setup

I changed a setting and new PV is ok but the AC load watts is not correct. It changes equal with the PV invertor watts. L1 watts is wrong at the AC loads.

Is the CT measuring the AC loads in the vrm portal? The electrician said he extended the ct with a longer cable. If there is something wrong with ct what will happen?

When pulling out CT then we have the following dashboard : seems a lot better.

So what does CT exactly do? Direction of the CT is ok.

Assuming the two Energy Meters are correctly linked to the Multi the CT is not necessary and will make its brain hurt. The Multi's internal CT is sufficient to measure the current difference going into/out of it.

Plugging in the external one will make it think it is seeing the same thing, but it is actually measuring L1 Grid which is why the calculated load (= Grid In + PV generation - current into Multi) equals the PV reading.

Please check in the advanced menu. Seems to be a VRM problem.

thanks, the problem is solved now.
