Solar repairs & servicing.
Inverter faults, blown isolators, systems that stopped producing or never produced what they should — we diagnose and fix any grid-connected solar system in Bendigo, no matter who installed it. CEC-accredited, fully tested, properly re-commissioned.
Common Bendigo solar faults — and how we find them.
Inverter faults and shutdowns.
The inverter is the part most likely to fail — it works hardest and runs hot through Bendigo’s 40-degree summers. We read the error codes, check for over-voltage trips (common at the end of long rural feeders), test the DC and AC sides, and tell you whether it’s a reset, a board repair or a replacement. A new string inverter for a standard home is usually $1,500–$3,000 supplied and installed.
Blown DC isolators.
The rooftop solar DC isolator is a notorious weak point on older Victorian installs — water ingress cracks the housing and the isolator fails or, in the worst cases, arcs. We replace failed isolators with a current-compliant, properly sealed unit and check the whole DC string while we’re up there.
Underperforming systems.
If your bills haven’t dropped the way they should, the system may be underperforming rather than dead. We test each string’s voltage and current against spec, check for shading from new tree growth, look for failed or mismatched panels, and confirm the inverter is actually exporting. Often it’s a single bad string dragging the whole array down.
Isolator, meter and connection issues.
Loose terminations, a faulty AC isolator, or a meter that was never configured to record solar export all quietly cost you money. We check the full connection path from panel to meter and rectify what we find — and where a meter reconfiguration needs Powercor, we lodge it.
Indicative 2026 pricing.
- Diagnostic call-out + minor fix: $150–$450 (isolator reset/replace, re-termination)
- Replacement string inverter (standard home): $1,500–$3,000 supplied & installed
- Full system health check & report: from $180
- Under-warranty faults: we help you claim it — often no cost to you
Why we don’t cut corners.
A faulty solar system isn’t just lost savings — arcing isolators and degraded DC connections are a real rooftop fire risk. As a Clean Energy Council accredited installer we diagnose to the root cause, repair to current AS/NZS 5033 and AS/NZS 4777 standards, and re-commission the system properly. We quote before any chargeable work — no surprises.
If your old system is beyond economic repair we can talk a fresh solar install or adding battery storage. Local detail for Strathdale. Need a fix now? Get a free assessment.
Solar repair FAQs.
Why has my solar system stopped producing?
Most often an inverter fault — a tripped or failed DC isolator, an over-voltage shutdown, or a dead inverter. Other causes: a faulty string, new shading, or a meter issue. We run a full diagnostic (error codes, string testing, isolator and meter checks) to find the real cause.
How much does a solar repair cost?
A diagnostic call-out and minor fix is typically $150–$450; a replacement string inverter $1,500–$3,000 installed. If it’s under warranty we help you claim it. We always quote before chargeable work.
Can you service a system another company installed?
Yes — much of our repair work is on systems whose original installer has vanished. As a CEC-accredited installer we diagnose, repair and re-commission almost any grid-connected system to current standards, whoever fitted it.
