I have a single phase 15kw system with three MultiPlusII inverters in parallel. There is no grid meter. The system is linked to four 150/100 MPPTS, with ESS set with battery life. I have noticed that recently the VRM Portal and the Cerbo shows that the incoming grid power (AC-In L1 Watts is in the region of 1.4-1.7kw, but the AC Input is 222Vx-3,5A (-777W) and the Wattage on AC-In L1 is showing 1755W, which is way higher. The Same is true for the output. What is causing this completely incorrect reading on the Power?
I have ESS set with a GridPoint of -200W, but the system continually shows a draw of around 1.4kw.
I have attached images from the Cerbo GX.
