TL;DR: Your retailer's app shows what your smart meter recorded: total household consumption, grid imports, and exports. Your inverter's app shows only what the panels produced. You need the first one to answer the question that matters, which is when you are buying grid power despite having solar.
Two Apps, Two Different Numbers
This trips up most new solar owners.
Your inverter app, whether that is Fronius Solar.web, SolarEdge, Enphase Enlighten or another, reports generation. It knows what came off the roof. Without additional hardware at the switchboard it does not know what your house consumed or what went to the grid.
Your retailer's app reports what the meter recorded: consumption, import and export, in 30-minute intervals. That is what you are billed on.
Generation alone tells you the system is working. It does not tell you whether you are using what you generate, and that is the number that decides your bill.
What the Smart Meter Actually Does
An old accumulation meter records one total and needs a person to read it. A smart meter records in 30-minute intervals and reports automatically, separating import from export.
That separation is why solar installations trigger a meter change. An accumulation meter cannot properly distinguish power flowing out from power flowing in, so feed-in credits cannot be calculated correctly without one.
The data goes to your retailer, and most retailers make it available through their app and web portal.
Getting Connected
- Confirm you have a smart meter. Your bill will say, or the meter itself will have a digital display rather than a spinning disc. If you have solar, you almost certainly have one.
- Download your retailer's app. AGL, Origin, EnergyAustralia, Red Energy and most others have one, free to their customers.
- Log in with your existing account details. The same credentials you use for online billing.
- Find the usage section. Labelled Energy Insights, My Usage, Solar Monitoring or similar depending on the retailer.
- Check that solar is flagged on your account. If exports are not showing, the account may not be configured as a solar connection, which is a phone call to fix.
Third-party monitoring platforms exist but rarely integrate directly with Australian retailer data. Most require their own hardware clamped at the switchboard, which is a separate purchase and a separate installation.
What to Look For in the Data
A useful app gives you daily and interval breakdowns of consumption, import and export in both kilowatt-hours and dollars, with historical trends and, ideally, alerts.
Live data is a nice feature and less useful than people expect, because most retailer feeds run several hours behind. Interval history is where the value is.
The First Thing to Check
Look at your data within the first month after installation.
You are checking one thing: that export is recorded as export. A meter wired so that exported power registers as consumption is not common, and it does happen. It shows as an unexplained jump in imports on sunny days, and it is far easier to correct while the readings are recent.
While you are there, confirm the feed-in credit is appearing on your account at the rate your plan specifies.
The Second Thing to Check
Find the hours when you are importing despite having solar.
For most households the answer is between 4pm and 7pm, when generation has fallen away and everyone is home. That is your target. Once you know how many kilowatt-hours land in that window and what you pay for them, you know whether the fix is shifting a few appliances or adding battery storage.
Using the Data to Cut the Bill
Shift the movable loads. Dishwasher, washing machine, pool pump and EV charging into the hours your solar panels are producing, typically 10am to 3pm. Every kilowatt-hour you self-consume avoids your import rate, which is three to six times your feed-in rate. Most appliances have a delay timer; set it once.
Find the constant draw. Look at your overnight consumption, when nothing should be running. A high baseline points at something drawing power around the clock, and the second fridge in the garage is the usual culprit.
Check your tariff against your pattern. If you are on time-of-use, the app shows exactly how much of your consumption lands in peak. If it is a lot and you cannot move it, a flat rate may cost you less. If it is little, time-of-use is working for you.
Decide on a battery with evidence. Consistent high evening imports and consistent daytime exports is the pattern a battery fixes. Size it to the evening import figure the app gives you, not to your daily total.
Where It Falls Short
Data latency is normal. Some retailers update several times a day rather than continuously, so treat the app as a tool for spotting patterns rather than watching the kettle.
The data is also aggregated at the meter, so it tells you the house drew 3kW and not what drew it. Circuit-level monitoring needs additional hardware at the switchboard.
If you switch retailers, the history usually does not follow you. Export anything you want to keep before the account closes.
Key Takeaways
- Your inverter app shows generation; your retailer app shows consumption, import and export. You need the second one.
- Smart meters record in 30-minute intervals, which is what makes accurate feed-in crediting and time-of-use billing possible.
- Check within the first month that export is being recorded as export, and that feed-in credits are appearing at the right rate.
- Use the interval data to find when you import despite having solar, then target those hours with timers or storage.
- The data is aggregated at the meter, so it identifies when you use power, not which appliance used it.
