Load seems to increase by around 0.5kwh when exporting from batteries

Any idea why this would happen? Nobody in the house, no heavy-load extra appliances switched on, yet the load seems to go up when exporting.
Before export, Discharge is 1.0KW, Total Load is 1.0KW nothing in or out from grid.
Export begins, Discharge at 4.0 KW, exporting at 2.5KW, Load goes up to 1.5KW at the same time.
I would expect to see Discharge at 4.0KW, Export at 3.0KW and load stays at 1.0KW or similar?
Any Ideas?

BEFORE EXPORT at 17:38

EXPORT STARTED at 17:39

I get the same with my system.
Guess it takes a bit more juice to convert all that extra DC to AC for exporting.
I can see it happening on the Android Inverter Monitor app (it reports inverter load).
When max exporting, the inverter takes about 400W, normally it is around 100 or less.

I get a similar "loss" with my GE kit.

3.6kW DC discharge raises the houseload by about 300W.
This is conversion losses DC to AC, most of which is heat, which is why inverters typically have big heatsinks to dissipate it.
