Professional inspection, testing and troubleshooting for residential and commercial solar systems that are underperforming, showing faults or need an electrical safety check.
Solar System Maintenance & Fault Finding Victoria
When your solar system needs attention
A solar system may continue operating even when one string, panel group, monitoring connection or protection device has a problem. A sudden change in generation, repeated inverter warnings or an unexplained increase in electricity use should be investigated rather than guessed at.
Maxim Energy provides practical fault finding and maintenance across Victoria. We assess the system as installed, explain what we find and recommend repairs only after the cause and scope are understood.
Low or inconsistent generation
Investigation of unexpected production drops, string imbalance, shading changes, monitoring data and other performance concerns.
Inverter or monitoring faults
Assessment of inverter error messages, shutdowns, communication problems and systems that appear offline in the monitoring app.
Electrical safety concerns
Inspection of accessible cabling, isolators, protection, connections and visible damage where a fault or safety issue is suspected.
What a maintenance visit may include
- Review of the reported fault and available monitoring history
- Visual inspection of accessible system components
- Inverter status, settings and recorded fault checks
- DC and AC electrical testing where appropriate
- String voltage and current comparison where accessible
- Assessment of isolators, breakers, labels and connections
- Identification of damaged, failed or incompatible components
- Testing after repair or corrective work
- Clear explanation of findings and recommended next steps
- Advice when network, meter or manufacturer support is required
- Assessment of older systems before battery or EV integration
- Documentation of work completed where applicable
The exact tests depend on the system design, site access and fault symptoms. Roof access, replacement parts and specialist manufacturer work may require a separate scope.
Common solar faults we investigate
- Inverter not producing or repeatedly restarting
- One string producing less than another
- Earth, insulation or isolation faults
- Tripped solar circuit breakers or protection devices
- Monitoring app offline while the inverter is operating
- Loose, weather-damaged or deteriorated components
- Unexpected electricity bills after a system change
- System issues after switchboard or meter work
- Older inverter replacement assessment
- Solar checks before adding a battery
A diagnosis before a replacement
Replacing an inverter or panel without confirming the fault can leave the original problem unresolved. Our approach is to separate monitoring issues, network conditions, equipment faults and installation problems before recommending corrective work.
With more than six years of solar and battery experience and over 1,200 installations, Maxim Energy can also assess how an existing system may interact with a future battery, backup system or EV charger.
Solar maintenance FAQs
How do I know whether my solar system is working properly?
Compare recent production with similar periods and check the inverter or monitoring app for warnings. Weather and seasonal changes affect output, but sudden or persistent drops should be investigated.
Can you repair a system installed by another company?
In many cases, yes. We first confirm the equipment, system condition, access and fault scope. Some warranty work may need to be handled by the original installer or manufacturer.
Does an offline monitoring app mean the solar has stopped?
Not always. The inverter may still generate while its Wi-Fi or communications are offline. The inverter display, status lights and electrical testing help distinguish a monitoring problem from a generation fault.
Do solar panels need regular cleaning?
Not every system needs routine cleaning. Roof angle, local dust, bird activity and visible soiling matter. Cleaning should be assessed safely and must not be treated as a substitute for electrical fault finding.
Can you check my solar before adding a battery?
Yes. We can review the existing inverter, switchboard, metering, available circuits and system condition before recommending a compatible battery solution.
What information should I send before booking?
Photos of the inverter, switchboard and any error message, plus the inverter brand/model and monitoring screenshots, can help define the likely scope before attendance.
Need help with a solar fault?
Send us the system details, fault message and any useful photos. We will review the information and advise the next practical step.
