Query regarding metering accuracy

[HirenThumar2702]

Good day, Support Team

I'm working on a single-phase Panel meter. Which provides import and export of both energy sources on Modbus

For metering purposes, we are considering the STPM3x family of ICs (STPM32, STPM33, STPM34).

I've attached one image from which we expect accuracy from the STPM3x metering IC.

I have some questions about the metering IC which I mentioned.

1. I did not find the export energy data register. So Does this Ic is provided? 
2. As per the attached accuracy table. Does this IC is suitable?

If this IC is not suitable as per our requirement so kindly suggest another metering IC.

Thanks
