Get an inverter fault or output change assessed.
Share the warning message and system details with NDR. Discuss fault diagnosis, maintenance and the repair or replacement options for your equipment.
An inverter warning
or a change in generation?
A fault message or an unexpected change in solar output is a reason to check the system. If you use a monitoring app, save the relevant dates and messages. A lower electricity credit on its own does not identify a system fault.
NDR provides solar inspections, performance testing, fault finding and repairs for Gold Coast properties. The team can assess inverter faults and discuss suitable replacement equipment where required. Tell us the system age if known, inverter model and what has changed.
For planned maintenance, share the installation documents and previous service records you have. If the system includes a battery, include that model too so any compatibility implications can be considered.
- Solar system fault diagnosis
- Inverter fault assessment
- Changes in generation investigated
- System inspections and testing
- Solar maintenance enquiries
- Suitable inverter replacement
- Repair or upgrade options
- Existing system records reviewed
Bring the system history
into the repair decision.
Look for a pattern in monitoring data rather than relying on one daily result. Generation varies with weather and season. Error messages, the date the change started and earlier records give the technician useful context for the assessment.
The system condition, diagnosed fault, available components and existing equipment all affect repair options. If an inverter replacement or wider upgrade is proposed, ask what will be retained, what will change and which compatibility checks are needed.
Ask about any attendance, inspection or diagnostic charges before booking; a free quote does not include every technical investigation. Share accessible information and photographs, and leave roof access, covers and electrical testing to qualified people.

What our customers say about NDR.
From our customers
The guys done a great job. On time all the time. Cleaned up after them selves. Explain how everything worked. Could not be happier. Thanks Nathan.
Excellent pricing, high-quality workmanship, and a very efficient installation. The entire team was professional and friendly—from the office staff through to the tradesmen and even the youngest apprentice. Communication was excellent throughout the process, the work was completed to a very high standard, and everything was left clean and tidy afterwards. I couldn’t be happier with the result and would highly recommend them.
NDR are professional, punctual and thorough. I have engaged them twice now, once to install an EV Charger for my client and a second time to fault find a commercial installation. On both occasionsI have been impressed by the quality of Nathan's work and the efficiency of their office.
From the first time I met Nathan he came to visit me at my apartment. We did a walk around. I particularly wanted my old system cleaned but not put under pressure as it was an 18-year-old system. He agreed to that no problem. He was exceptionally knowledgeable in his details of. The air-conditioning units they capabilities warranties installation process complying with body corporate requirements, etc. He wasn’t too pushy or over the top. I genuinely liked his style. We agreed to having 2x 2.5 kW Aircon units Install installed one in each bedroom. This necessitated One unit being wall mounted on brackets as I was on the second floor the second was mounted on my balcony. The team came in at 11:30 am exactly on time and finished around 5 pm fantastic Highly recommend them and Carly in the office was absolutely outstanding.
Nathan and the team were amazing! My partner and I live in a rental and needed our aircon cleaned and with the warmer weather coming we wanted it done asap and they responded so promptly that we had the job done within the week!

Exceptional service from NDR Trade Solutions. Communication was prompt and professional, the booking process was easy and the turnaround was excellent. Nathan and his team arrived on time and did a thorough, meticulous clean of multiple split-system air conditioners. The difference is amazing, the units are spotless, fresh and beautifully deodorised. They were professional, efficient and left everything clean and tidy. We were really impressed with the quality of the service and attention to detail. I'II definitely be having the split systems professionally cleaned annually and would highly recommend NDR Trade Solutions.

I have no hesitation in recommending Nathan and his team for any future installations and would call on him if I needed any extra work. Michael Rogers
Nathan and Corey have once again saved the day by sorting out how to provide ethernet internet to our computers on the first floor which is not close to the NBN outlet.

A few questions,
before you book.
Questions about inverter faults, changing generation, maintenance and the scope of solar repairs.
Do you offer solar panel cleaning, servicing and repairs?
Yes! We provide solar panel cleaning, system inspections, performance testing, fault finding and repairs to help maintain system efficiency and safety.
Can you replace a faulty solar inverter?
Yes! We can diagnose inverter faults and supply and install suitable replacement inverters, including upgrades where required.
Can I upgrade my existing solar system?
Absolutely! We can assess your existing system and recommend additional panels, inverter upgrades, battery storage or a complete system replacement.
Do you offer free quotes?
Yes! We offer free, no-obligation quotes across all our services, including electrical, solar, battery and EV charging.
Why has my solar generation dropped?
Output varies with weather and season, while shade or a system issue can also affect generation. Monitoring history and inverter messages help determine whether assessment is needed. Note when the change began and share comparable records if available; a single low-output day cannot identify the cause.
Does an inverter error mean it needs replacing?
Not necessarily. The code and operating conditions need assessment before the repair or replacement options are clear. Send the exact message and inverter model. NDR can diagnose inverter faults and advise on suitable replacement equipment when that is the appropriate solution.
How much do solar repairs cost?
The fault, system type, components, access and work required determine the scope. Confirm any attendance or diagnostic charge when arranging assessment. Once the issue is understood, ask what the proposed repair includes and whether any related equipment changes are required before agreeing to the work.
Can panel cleaning replace a solar-system inspection?
Panel cleaning and technical inspection address different needs. Cleaning can be considered where dirt or debris is a concern, but it does not establish the cause of an inverter fault or verify the whole installation. Describe both the cleaning need and any performance issue so the scope can be agreed.
How often does my solar system need maintenance?
Check the maintenance guidance supplied with your equipment and installation. The system, site conditions and any faults or damage influence what needs attention. Share your records with NDR to discuss an appropriate scope rather than assuming every solar installation needs identical work at a fixed interval.
What should I send before a repair assessment?
Include your suburb, inverter and battery models, the exact fault message and the date you noticed the issue. Monitoring screenshots and installation documents are useful if available. Only take photos from safely accessible locations; do not climb onto the roof or open electrical equipment.
