Replacement Inverter

I apologise in advance if this has already been covered before, as this is my first post.

I have solar panels and house battery set up, and my solar ran through an Elster Generation meter.

Batteries ran through a Emlite M22, this meter was ignored, because I only needed Generation readings provided by my Elster for Fit purposes.

Due to complications with my set up. I have had my solar inverter and batteries taken out of my loft and repositioned in my garage. A 3 day job, but a very professional installation.

The Hybrid inverter which came with my batteries has now been commissioned, the old Elster meter removed and everything is running through the Emilte.

Complicating matters is that the wifi dongle on inverter will not connect to my wifi, despite multiple attempts and efforts to do so. Consequently, I have ordered an ethernet dongle and cable. Hopefully to be connected this coming week, once it arrives.

Now to the real issue. I am on the original Fit tariff. Just Generation payments, no export, other than the half generation total.

With this Emlite EML M22 (ECA2.nz V1). I cannot identify pure Solar Generation figures. I have tried to follow the logic of Import/Export and Net. But none of these readings come close, to what I have been producing and what I have had forecasted.

In fact the Net figure moves up and down.

I would just like to know how I find my true Generation figure so I can report it for my FiT readings.

Hopefully, someone here can steer me in the right direction.

I can provide readings from my install date if that helps.
