System power generation Result was created by DAWON KIM
Hi! , I have additional questions.
I do not know why negative values ​​are generated in "System power generation". The power generation of the system is generated from the inverter? Is it negative because the battery is used? And I think the overall power generation is low, so I wonder if this amount of power generation is the general amount in the house.
I am not Sure of my intervention.

Hi Dawon,

"System power generated" is power at the grid connection point. For systems with batteries, negative power indicates the battery is being charged from the grid. It may also indicate grid power for inverter power consumption at night.

Best regards,
Paul.
