Deviation between SolarEdge consumption data and PVOutput values


The production is spot on:

e.g Aug 4, 2019

1326,854 kWh

1326,854 kWh


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

1127,778 kWh

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.


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