Power reading variation on 3080t bidirectional meter vs. power reading of Microinverters

I have installed my 3080t bidirectional meter for a split phase system by setting the Ctriato to 2 and after restarting the power of the microphone vs the bidirectional meter is not the same, it gives me 20% less

This is an interesting question.

Please let me know how you do the comparison (the key is how to keep the comparison at the same time points?).

1 how do you get the instant power reading from the microinverters? (please provide the photo to illustrate how do you read the data from the inverter, and confirm the refresh frequency )

2 how do you get the instant power reading from IAMMETER`s product?

If you read the data from IAMMTER-cloud, the data refresh is 1 min ,not timely
Recommend using this API to read the instant power value

Gracias por su pronta respuesta.

Aclarando tu consulta:

1 ¿Cómo se obtiene la lectura instantánea de la potencia de los microinversores? (proporcione la foto para ilustrar cómo lee los datos del inversor y confirme la frecuencia de actualización)

Resp. La actualización es en el mismo intervalo de tiempo, en ese caso 1:26 pm puede verificar en la foto de la aplicación web de escritorio, la captura de pantalla de la aplicación móvil de los

microinversores 2 ¿Cómo obtengo la lectura instantánea de energía del producto IAMMETER?

A través de la aplicación web de escritorio.

En consecuencia, surge mi preocupación porque si ves la medición de los microinversores, la potencia de salida de la casa es:

Arrelgo #1 = 678w
Array #2 = 458w
Array #3 = 226w

Total Micro= 1,326w

Total indicando IAMMETER = 920w

Diferencia de lectura 442W que representa el 33% de la generación.




Hi:

First ,the data displayed on the dashboard below refreshes only every 5 minutes and represents the sum of the three-phase power values, making it unsuitable for accurate comparison.



Second,

If you enable the "CTCratio" and set it two "2", it means the inverter would be adual phase balanced output ,why there are three different power output in your picture?

I think the data below is three inverters output , not three phase of one inverter, yes?

"Arrelgo #1 = 678w

Array #2 = 458w
Array #3 = 226w"

If so ,you do not need to set the "CTCratio" ,just keep the value to 1. And use the 3phase of WEM3080T to monitor the 3 inverter`s power output.

Then you can use this page to compare each phase power reading with individual inverter power output.
