CCGX V3.55
Build date 20250403132010

Battery 2xPylontech 5000 fully charged

PV invertor Aurora One PVI-3.6-TL
connected to AC output 1

AC output 2 is always on. Not sure this is important.

grid code G98/1Amendment 6 (16A max)

Normal operation with Solar power battery fully charged

NO solar Loads powered from grid NO inverting

NO grid Inverter starts and powers loads

Any ideas where i may have gone wrong.

One thought my loads are usually quite low.

How did you set ESS on the GX?

[Llygad (Colin)]

Yes with the CCGX

[chrigu]

Yes, but which setpoint did you set to which setting, which ESS mode, is self consumption set to all loads, is there a feed-in limt, so on

[Llygad (Colin)]

Where is self consumption set I don’t see this?

[chrigu]

Ah, yes, CCGX with VenusOS 3.55, that might be the cause for that setpoint to be missing. It would be between Grid Meter and Multiphase regulation. Im not quite sure then.

Is your gridcode allowing for DC feedin from battery?
Does the behaviour change if you set Multiphase to Sum of all phases?

As a sidenote, are you sure that your AC PV inverter is capable of running in island operation connected to the ACout? Does it support the necessary frequency-power-curve?

[Llygad (Colin)]

Yes grid code Allows DC feed in but not using DC MPPT generation at present.

I’ll try Multiphase, see if that helps.

[Llygad (Colin)]

Multiphase dose not alter the situation.
