Greens' subsidies on solar

[harm_less]

My friend cant put out anymore than 5KW on his street because his street cant handle it he tells me.

That is the case in regard to most lines companies but more accurately the 5kW maximum is per phase. For properties with 3 phase power connections they can double up to 10kW (or beyond if you are brave enough to accept the volatility of export prices based on the wholesale electricity market as >10kW aren't able to export under domestic terms).

The 5kW cap per phase is to avoid unbalancing the local grid phases which poses a potential risk to supply infrastructure. In our case we have 9kW all connected to one phase and the inverter is set up to throttle back our export to 5kW maximum. We work towards consuming as much as possible via EV charging and HWC diversion to avoid our 'excess' generation (which is exported to the grid) reaching 5kW.
