Sunsynk 8kW - Micro Inverter Input Test

[Brickman]

Wanted to test the functioning of a Grid Tied inverter as input on the Aux port of my 8k Sunsynk with battery storage.

Ran a temporary cable from my 2nd,  Grid tied, 8kW Sunsynk into my Aux port and simulated a grid outage to run the batteries down to the 96% start up setting.

It worked as described -  the only problem being how the input power is displayed.

On the flow diagram the Aux input shows only 2w when the input was actually around 800w.

That is not the strangest.

When I stopped the test by changing the setting back from Micro Inverter to generator,  the Aux and the UPS displayed 32,700w and 33,300w respectively.

It stayed that way until I restored grid input and then normalized.

Any idea of what it can be ?
