The Northern Rivers was an early adopter of solar, which means a lot of Byron systems are now well into their second decade, and the inverter is almost always the first thing to go. If yours is flashing a fault, showing an error code or has simply gone quiet, Tom Sexton’s local team diagnoses and replaces inverters across Byron Bay and the Northern Rivers, including systems we did not originally install.
Panels routinely outlive their inverters. An inverter works hard every daylight hour in coastal heat, humidity and salt air, and after ten or more years of that, faults stop being worth repairing. Worse, many of the companies that installed the region’s early systems are gone, leaving orphaned systems with nobody to call. We take those calls every week.
The warning signs are usually clear: fault lights or error codes on the display, a monitoring app that has gone silent, or a power bill that has crept back up to pre solar levels because the system has quietly stopped producing.
A straight like for like swap is sometimes the right call, and when it is, we say so. But an inverter replacement is also the natural moment to think about batteries, because a hybrid inverter installed now can save you paying twice later. Tom quotes every replacement with an eye to future battery compatibility: if a hybrid model costs a little more today but makes a battery a clean bolt on rather than a rework, you will see both options priced side by side and the reasoning in plain English. No pressure either way, just the trade off laid out.
Not every dead display means a dead inverter. We start with a proper diagnosis: the inverter itself, the DC isolators that fail notoriously often in coastal weather, and the condition of the array feeding it. You get a straight verdict on what has actually failed and what it costs to fix. If the whole system is at the end of its useful life, we will tell you that too, because putting a new inverter on tired panels is sometimes money down the drain.
Where an inverter lives affects how long it lasts, and Byron punishes bad placement. An inverter cooking on an unshaded western wall, or sitting in salt laden airflow, ages years faster than one mounted in a garage or on a protected southern wall. When we replace yours, we reassess the location rather than automatically reusing the old spot, and on flood prone sites we mount it high, a practice we apply across the region and cover on our Northern Rivers page.
Tell us the symptoms, and the inverter model if you can read it. Photos help.
We confirm what has actually failed before anyone spends money on hardware.
Like for like and hybrid battery ready options priced side by side, fixed in writing.
Most replacements are done in well under a day, tested and producing before we leave.
New app monitoring set up on your phone, so the next fault never goes unnoticed.
Inverter replacement pricing depends on the size and type of your system, whether you choose a standard or hybrid model, and the condition of your isolators and switchboard, so we do not publish a one size figure that would only mislead. Tell us your inverter model over the phone on 0420 141 078 and we will give you a realistic range on the spot, then fix it in writing after a site check.
If your panels are also more than a decade old, a full replacement system can be better value than a standalone inverter swap. Our current 6.6kW systems start from $6,990 installed before rebates, with new panels, new inverter and fresh warranties across the lot. We will price both paths for you honestly.
Not necessarily. Some faults are grid side, some are failed isolators, and some are genuine end of life. That is why we diagnose before we quote hardware. Send us the model and the code when you call and we can often tell you over the phone whether it is worth a repair, a warranty claim or a replacement.
It depends on whether a battery is realistically in your future. If it is, a hybrid inverter now means the battery later is a clean addition instead of a second inverter project. If it is not, a quality standard inverter is the cheaper and simpler fix. We price both options side by side on every quote so you are choosing with real numbers, not a sales pitch. Our batteries page covers what the storage side looks like.
Yes, we service orphaned systems every week, it is one of the most common calls we get. We inspect the whole system, not just the inverter, flag anything unsafe or non compliant from the original install, and once we have replaced the inverter you have a local business behind it for the life of the system. Get in touch and we will take it from there.
