Perth solar fault diagnosis and repairs
Solar Repair Perth
Australis Solar provides solar repair services for Perth homes and businesses experiencing inverter faults, low or zero output, monitoring errors, damaged wiring or solar panel problems. Our accredited in-house installers and licensed electricians assess the inverter, array, isolators, switchboard, metering, monitoring and connected battery or backup equipment before recommending the appropriate repair, replacement or upgrade.
We service Australis Solar installations and can assess many systems installed by other companies, subject to safe access, brand compatibility, documentation, parts availability and the condition of the existing system.
Provide the inverter fault code, system brand and monitoring screenshot where available. We will use this information to determine the appropriate next step.
Recognising a solar system fault
When should you book a solar repair?
A fault is not always obvious. Some systems stop completely, while others continue generating at a reduced level or lose their monitoring connection. These signs warrant further investigation.
Inverter fault code
The inverter displays a red or amber light, warning message, isolation fault, grid error or another recurring code.
No or low solar production
Your system is producing nothing or substantially less than expected for the weather, season and installed capacity.
Monitoring is offline
The monitoring app has stopped updating, contains data gaps or no longer matches the inverter or electricity meter.
Switches keep tripping
A solar circuit breaker, safety switch or isolator repeatedly trips or cannot remain in its normal operating position.
Visible or storm-related damage
You notice damaged panels, exposed cabling, moisture, pest damage or a problem following a storm or building work.
Unexpected Synergy bill increase
Grid consumption has increased without an obvious change in household usage, suggesting the solar system may not be offsetting energy as expected.
Do not remove equipment covers or touch damaged cables. If there is smoke, fire, arcing, melted equipment or immediate danger, move away and call 000. Follow the documented shutdown procedure only when it is safe to do so. Read the WA Government solar PV safety guidance.
Whole-system fault assessment
What our solar repair assessment covers
Solar faults can involve more than the panels. Australis Solar examines the connected components and available performance information to identify the likely cause rather than automatically replacing the first component showing an error.
The assessment scope depends on the fault, system design, roof access, equipment condition and whether solar, battery storage, backup or energy monitoring equipment is connected.
Components and information we may assess
- Inverter status, fault history and operating data
- Solar panel strings, connectors and accessible cabling
- AC and DC isolation, protection and switchgear
- Switchboard condition and relevant circuit protection
- Metering, current transformers and monitoring communications
- Export controls and connected energy-management equipment
- Battery gateway and selected backup circuits where applicable
- Roof access, shading, physical damage and array condition
- Production history, energy usage and recent Synergy bills
- System age, serial numbers, warranties and manufacturer support
Fault diagnosis and practical solutions
Common solar repair services in Perth
The correct solution depends on what has failed and whether compatible, manufacturer-supported components remain available. Australis Solar will explain whether the system can be repaired, requires a component replacement or would be better addressed through an upgrade.
Inverter fault diagnosis
Assessment of inverter errors, shutdowns, grid faults, communication problems, external protection and replacement compatibility.
Panel and string faults
Investigation of underperforming strings, damaged modules, connectors, cabling, water ingress and accessible array components.
Low-output assessment
Comparison of system production with the installed capacity, roof layout, shading, seasonal conditions and available monitoring data.
Monitoring and metering faults
Troubleshooting of monitoring connections, data gaps, Wi-Fi communication, meters, sensors and inaccurate energy-flow information.
Battery and backup integration
Assessment of compatible battery, gateway, monitoring and backup-circuit faults connected to the solar system.
Repair or replacement planning
Clear advice on component repair, inverter replacement, system upgrades, switchboard requirements and future battery or EV goals.
Not sure what has failed?
Send the fault code, inverter model and available photos through the booking form. We will determine the appropriate assessment pathway.
From fault code to tested solution
How the solar repair process works
We begin with the information already available, then determine whether remote troubleshooting, manufacturer support or an on-site electrical assessment is required.
Submit the fault details
Provide the property address, system age, equipment brands, fault code, photos and monitoring screenshots.
Initial triage
We review the information, check likely warranty or manufacturer pathways and confirm whether a site visit is appropriate.
On-site assessment
A licensed electrician investigates the relevant solar, electrical, monitoring, battery or backup components.
Repair, test and explain
We outline the available options, complete approved work and test the affected system functions before handover.
Chargeable work, replacement equipment and additional approvals depend on the fault, warranty status, system condition and agreed scope. A diagnosis does not guarantee that every older or unsupported system can be economically repaired.
Making a practical long-term decision
Should you repair or replace an older solar system?
A targeted solar repair is often appropriate when the fault is isolated and the remaining system is safe, compatible and suited to the property. Replacement may provide better value when equipment is obsolete, faults are recurring or your energy needs have changed.
A repair may be suitable when:
- The fault is isolated to a serviceable component
- Compatible replacement parts remain available
- The array and electrical equipment remain in suitable condition
- The existing capacity still meets your energy needs
- The repair preserves a practical and supportable system
Replacement or an upgrade may be better when:
- The inverter or other equipment is obsolete or unsupported
- The system has repeated or multiple component failures
- Replacement parts are unavailable or incompatible
- The existing system is substantially undersized
- You are preparing for battery storage, backup or EV charging
Need more than a like-for-like repair?
Australis Solar can design an upgrade around your Synergy bill, roof, shading, actual usage, switchboard, backup needs and future battery or EV goals.

Solar repair questions
Frequently asked questions
These answers explain the usual first steps. The actual fault and available repair options must be confirmed from the system information and, where necessary, an on-site assessment.
Why has my solar system stopped producing?
A solar system can stop or reduce production because of an inverter fault, a tripped protection device, a damaged cable or connector, a panel or string issue, a metering or monitoring problem, shading, or another site-specific fault. A monitoring app that is offline does not always mean the system has stopped generating, so the inverter, meter and production data need to be checked.
What should I do if my inverter shows a fault code?
Photograph the screen, record the exact code and time, and check the owner manual for safe user-level guidance. Do not remove covers or attempt electrical repairs. Send Australis Solar the inverter brand and model, fault code and monitoring screenshot so we can determine whether remote troubleshooting or a site assessment is appropriate.
Can Australis Solar repair a system installed by another company?
Yes, Australis Solar can assess many systems installed by other companies across Perth. Whether we can complete the repair depends on safe access, brand compatibility, documentation, parts availability, system condition and whether specialist manufacturer support is required.
Is solar repair covered by warranty?
Warranty coverage depends on who installed the system, the workmanship warranty terms, the product warranty, the fault cause and the system age. For Australis Solar installations, we will review the applicable records. For third-party systems, the original installer or manufacturer may need to manage the warranty claim. Any chargeable work should be confirmed before proceeding.
Can a faulty solar inverter be repaired?
Some inverter issues can be resolved through configuration, communications, external protection or component work, while other failures require inverter replacement. The practical option depends on the fault, inverter age, manufacturer support, compatible replacement models and whether the existing solar array remains suitable.
Do you repair solar batteries and blackout backup systems?
Australis Solar can assess faults involving compatible battery storage, gateways, monitoring and backup circuits connected to a solar system. Backup capability varies by system, and not every battery supports whole-home backup. Brand support, warranty status, installation condition and parts availability will affect the available repair options.
How much does solar repair cost in Perth?
The cost depends on the fault, system size, roof access, testing required, replacement parts, warranty status and whether network or switchboard work is needed. Provide the system details and fault information through the booking form so Australis Solar can confirm the appropriate assessment and explain any chargeable work.
