What Fault Finding Customers Say

★★★★★
"My inverter had an error code I didn't understand. Response came out same day, diagnosed an earth fault, and coordinated the fix. Back up and running in 48 hours. Saved me so much downtime."
Thomas M.
Business owner, Cottesloe
★★★★★
"System wasn't generating anything. Response's thermal imaging found a failed panel with a hot spot. They explained everything clearly and replaced it. Generation is back to normal."
Sarah J.
Property owner, Mosman Park
★★★★★
"Our system dropped from 5kW to 2kW in a week. Response ran full diagnostics, found a DC cable fault, and had us generating at full capacity the next day. Professional and fast."

Common Questions About Solar Fault Finding

What's the cost of solar fault finding? +
A full diagnostic visit costs $199–$399 depending on your system size and complexity. This includes thermal imaging, electrical testing, and a detailed report. The diagnostic fee is usually waived if you proceed with repairs through us.
Can you fix the fault on the same day? +
It depends on the fault. Simple fixes like a tripped RCD or a blown fuse we can handle same-day. If a panel or inverter needs replacement, we coordinate parts and schedule repair within 1–3 days.
What testing methods do you use? +
We use thermal imaging (infrared camera), DC voltage and current testing, insulation resistance megohm testing, earth leakage detection, and inverter software diagnostics. All tests are non-invasive and safe.
How long does a diagnostic visit take? +
Typically 2–4 hours depending on system size and complexity. We'll inspect panels, test inverter, measure DC voltages, check wiring, and take thermal images. You'll get a detailed report before we leave.
What if you can't find the fault on-site? +
Rare, but if the fault is intermittent, we'll set up remote monitoring or schedule a follow-up test. We'll provide hourly logging data to pinpoint when the system fails and why.
Do you work with other installers? +
Yes. We can diagnose systems installed by anyone and work with your original installer for repairs. We're vendor-neutral and all our reports are transparent.
