Wrong Load math calculations with PV inversor in iammeter aplication

hi,

I think the iammeter aplicattion is doing the wrong math when an invertor is added to the grid system.

I have two meters. 1 connected to the grid and other connected to my solar invertor. when I'm producing -886W and grig meter is reading 359W the apllicaton shows that my load is -1245 W. this means that the math its doing is -886-359=-1254W wicht is wrong. the correct math sould be -886+359=-527W.

I'm I right? can anybody help?

thanks?

HCoutinho.

sorry,

its all good. My mistake. I instaled the PV CT in the opposite direction L->K instead of K->L.

Now it is ok.
