Deviation between SolarEdge consumption data and PVOutput values


#1

The production is spot on:

e.g Aug 4, 2019

https://pvoutput.org/intraday.jsp?id=52387&sid=47624&dt=20190804

PVOutput:
1326,854 kWh

SolarEdge
1326,854 kWh

Perfect.

However, also the SolarEdge modbus energy meter is installed for the consumption;

PVOutput:
1127,778 kWh

SolarEdge:
1170 kWh

3,6% difference?

On another installation I see a similar difference.

What can it be and how to solve it?

Best regards.

SolarEdge API only provides consumption at 15-minute intervals which will affect the total amount over a longer period of time.


#3

Ok, but solar production is also provided at a 15 minute interval and that one is perfect.
