Your inverter app is the difference between noticing a failed string next week versus next spring. Australian homeowners should learn a short daily and monthly checklist: generation vs expected sun, self-consumption share, export volume, fault codes and grid events. This guide translates common dashboards into actions — and explains when to call a CEC-accredited technician instead of guessing.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.

Look at today’s PV generation (kWh), household consumption, grid import and grid export. On a sunny Adelaide or Brisbane day, generation should rise smoothly with irradiance; flatline generation under a clear sky usually means an isolator, string or inverter issue. Compare against yesterday and against a similar clear day last month. Apps differ, but those four flows tell you whether solar is actually displacing imports. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
If you export most of your midday energy at 2–8c/kWh while importing expensive evening power, the financial story is weak even when the app looks “green”. Shift flexible loads — hot water, dishwashing, EV charging, pool pumps — into solar hours. Battery owners should watch charge/discharge cycles and usable state of charge, especially after enrolling in a VPP that may discharge on grid signals. Model bill outcomes with a conservative FiT (often 3–5c/kWh stress-test) and your real weekday daytime load — exported energy rarely beats displacing retail imports in 2026. Photograph your switchboard and roof planes before quoting day to cut variation risk.
Winter in Melbourne and Hobart naturally cuts yield; do not panic on June output alone. Instead track specific yield (kWh per kW installed) across seasons. Sudden drops relative to nearby weather suggest faults. Soiling after dust storms in inland NSW/WA or pollen seasons can also suppress output until a safe clean is scheduled. Use Bureau of Meteorology context when judging “bad” days. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
Modern inverters log over-voltage trips, frequency events and isolation alarms. Repeated grid over-voltage may point to export congestion on your street — a DNSP conversation, not a panel replacement. Midday clipping on oversized arrays feeding smaller inverters can be normal. Screenshot codes before they clear and send them to your installer with timestamps.

Watch usable state of charge, cycle count and backup reserve settings. If the Cheaper Home Batteries Program helped fund the pack (~$372/kWh usable), you still need the battery to cycle productively. A pack that sits full all day and empty all night may be mis-sized or poorly scheduled against your tariff. Adjust modes with installer guidance rather than random app tapping. Size usable kWh to your 4pm–9pm consumption, confirm CEC listing, and keep federal (~$372/kWh usable) and any state battery support itemised — never as one mystery “government discount”. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
Call a CEC-accredited technician for persistent zero generation, burning smells, ground-fault alarms, water ingress signs or communications loss that survives a router reboot. Keep your commissioning documents handy. MrSolar can help you find accredited service partners if your original installer is unresponsive — preventative attention beats warranty arguments after roof damage spreads. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots.
