Yes normal, there is no shunt measurement in the phoenix (so the system tries to calculate the value instead), which is why you have added the BMV for accuracy.

Also unless you have a DC system and an extra shunt for measuring it, disable that tile. Everything in and out of the battery is reported by the BMV.

update .....


ok , i not like a 1000$ equipment have this error for measure.....

i have a carlo gavazzi meter et112 , and sometimes the error is about 40-50 w. Also measured with clamp meter.

Is possible avoid reading AC power for phoenix inverter and show measures of the carlo gavazzi meter et112? i configured the et112 as a "ac load" and it no show in the vrm portal.

For showing in vrm portal i have configured as a grid meter but show for duplicata in ac load and ac in.

Any idea? thanksss
