#Boekel

Sorry this time in english.

My 3fase Ess system 3x 48v-5000 multi plus parallel connected to grid

Also the SMA pv inverter is parrelel connected,

2x Energy meter one on the grid connection one on the SMA,

CCGX to control the system

Set the correct grid code

Everything is connected and working only the multi's won't send Any battery power (100% charged) back to the grid, also on the ccgx there is no pictogram of the grid only pictogram of A-C loads.

Did the grid connect at all?

If you look at the Multi's (under 'devices' - 'multi') is AC-in detected?

If AC is measured, my first guess will be the incoming phases not connected in the right order.
