Solar feed-in rules for three phase Residential

Leon-4019 — Sun, 28 Sep 2025 06:54:23 GMT

Hi, I have a 10kWh 3-phase home inverter with AGL in Brisbane.
Can someone please advise whether the AGL daily export is combined across all phases (10kWh at 8c max), or for each phase (3x10=30kWh at 8c)?

While not 100% sure Leon, I'd bet it just the max 10kwh overall at the special FIT, before it drops to the lower rate.

You know the advantages of 3 phase it seems, keeping in mind some 10kw inverters will only export at 5kw anyway.

Do you have flexible exports up there ?

We can export between 1.5 and 10kw (per phase), and the upper figure is usually what exports seem to be here in SA where I am.

Hi Lester, thanks for your input. I believe my Sungrow SH10RT is limited to 10kWh FIT, whether it's for one or shared across all phases.

Seems that is the max export output, which is per phase.

It can be limited by settings, which are set to the DNSP's requirements.

Eg. I think you are Energex ?

Google . . .

In Brisbane, standard Energex export limits are 5kW for single-phase and 15kW (5kW per phase) for three-phase connections, but these can be increased with an export-limited inverter or by joining Energex's Dynamic Connections program. The Dynamic Connections program allows for more flexible, higher export limits, sometimes up to 10kW per phase, but it can be automatically reduced during grid congestion or emergencies.

This is like our flexible exports with SAPN in SA, and I guess your solar people had you connected with your 'dynamic connections' progamme up there ?
