Wrong Load Usage on Solis S5-EH1P5K-L

[TiagoGomes]

Since you got a new 100A to 100mA (1:1000) CT installed, I guess all you have to do is set the CT (or CT1) to 100A in your SDM120 menu.

It makes sense because the first time I saw the CT value (I'll assume it came like that from the factory and that the company that did the installation didn't change it), it was already set to 100A (meaning it was ready to work with the original CT). But yes, I confirm that my CT (or CT1) is set to 100A, and now I’m sure that the consumption and export/import values to the grid are correct.

The previous CT you had was 100A to 33.3mA (1:3000) equivalent to 300A to 100mA, so perhaps it could have worked by setting CT to 300A in the menu to correct in the other direction... if that value was available from the list.

Yes, 300 was indeed one of the available values I could set for CT1. However, I’m glad I asked the company to install the original CT, this way there’s no doubt that the recorded values are correct, whereas if I had kept the old CT, even if I set CT1 to 300, I would always be unsure whether the values were accurate.

Just a "tiny" difference in the values... (Both days with the same PV value)
- With the old CT


- With the new/original CT


Well, once more, thank you so much for your help @peufeu !!
I'm 100% sure that without your help, I would have never discovered the problem on my own.
Take care!
