Cranbourne's power and housing
Which network are you on?
AusNet runs a Cranbourne zone substation and a terminal station nearby. But United Energy's Langwarrin zone substation supplies Cranbourne South and Botanic Ridge. Your bill names your distributor: AusNet's faults line is 13 17 99, United Energy's is 13 20 99.
An 80s and 90s boom
Industry spreading south from Dandenong drew housing from the 1950s, and building exploded in the 1980s and 90s. Big estates followed in Cranbourne East, Botanic Ridge and Cranbourne South.
More solar than AusNet planned for
AusNet says rooftop solar on its network is running about 25 per cent above forecast, which makes voltage harder to hold in range. Its Cranbourne, Narre Warren and Berwick North zone substations are all in its voltage management program.
A third of homes rented
At the 2021 Census, 33.8% of Cranbourne's occupied homes were rented and 80.0% were separate houses. Every one of those rentals now needs a 2-yearly electrical safety check.
Why solar owners in Cranbourne call an electrician
If your inverter keeps dropping out on sunny afternoons, high voltage on the street is one possible cause. An electrician can check your side of the meter: the cable run, the connections at the board and whether the inverter is set up correctly. If the problem sits on the network, they'll tell you to take it to your distributor.
New, upgraded or replaced solar now needs an emergency backstop, so the inverter has to stay online. On AusNet's network that applies to systems up to 200 kW installed, upgraded, repaired or replaced since 1 October 2024. On United Energy's, a system with no internet connection is held to zero export.
Older boards are the other thread. If your house is from the 1980s, ask which circuits its safety switches actually cover, because boards of that age often protect some circuits and not others. Switchboard upgrades for solar and EV chargers explains what changes.
Inverter tripping: your part and the electrician's
You can
- Note the error code on the inverter's screen and the time it happens
- Find your distributor's name on the electricity bill
- Reset a tripped safety switch once, and leave it off if it trips again
Leave to a licensed electrician
- Testing the voltage at your meter and board
- Any work on the switchboard, cabling or solar isolators
- Fixing the fault and giving you a Certificate of Electrical Safety
If it were our house in Cranbourne
We'd find the distributor's name on the bill first, because it decides who you ring for outages and who approves solar and batteries. Then, if the board is original to a 1980s or 90s build, we'd have it checked before adding a battery, an EV charger or more panels.
