High ac input consumption on 10000va

We are running a client on ESS with AC out2 as not critical programmed, we are seeing a value of 2.5-3a/HR @230v the moment the input contact activate. This is a lot higher than the intended self consumption mentioned. We would like the know why this is. We do have a grid meter et112 installed set at 20w. The ccgx can't manage the drain from input below 450 w. Please assist,,,:setup 48/10000/100*2 & mppt 250/100/48 smart, bmv 700 -standard 500a shunt, ESS, ACout2 activated and de-activated with assistant. With vrm

Hi @Meiring

Where exactly do you see / measure this current?
What is the VRM name / identifier?

The current is measured on the main incomming AC from the utility.

There after sit a ET 112 to see and try prevent gridfeed since we are not allowed to feed back. The ccgx does not read this high however. You may ask my manager/direct saal@solargysa.co.za or on my profile meiringpretorius@gmail.com on the vrm site. It is under Koos Snyman, Parys South Africa. Kind regards and thank you for the feedback so far. Meiring

Hi @Meiring

Ok, indeed on the grid-meter this current is not measured, so how do you measure this?

Do you thing the grid meter is faulty?

This input current could be an indication of high reactive power and low power factor, it's not certain it is active power. As far as I know, the CCGX reports only the active power.
