Can Solar Power Inverters be Repaired?

Whether an inverter can be repaired often depends on the brand. Many manufacturers have closed down, making parts inaccessible. However, in many cases, simple components like fuses, plugs, or cables can be replaced. Leading brands may also allow the unit to be sent back to the manufacturer for refurbishment.

Sometimes, a “faulty” inverter only needs a professional reboot or a firmware update. In other cases, we may recommend a complete replacement. Every day you spend with a faulty system costs you money on your power bill. Our solar electricians will provide the best advice on whether to repair or replace.

“A 2025 Adelaide solar health check report found that nearly 70% of reported inverter faults were actually caused by external issues like moisture in rooftop isolators or degraded DC wiring.” — SA Solar Industry Standards 2026.

Common Causes of Inverter Failure

While many customers call us for a new inverter, the inverter itself is often not the primary problem. Common external issues that cause an inverter to shut down or show an error include:

Faulty Solar Wiring: Degraded DC cables or loose connections.
Failed Rooftop Isolators: Water ingress into isolators is a leading cause of system failure.
Damaged Panels: Broken plugs or micro-cracks in the solar cells.
Environmental Factors: Damage from hail, lightning, or power surges.
Incorrect Installation: Inverters installed in direct sunlight can overheat, voiding the warranty.

FAQ

Solar Inverter Service & Repair FAQs

An isolation fault usually means there is a leak of electricity to the earth, often caused by moisture in the wiring or panels. You should turn off the “Solar Supply Main Switch” in your switchboard and call us. We aim to attend within 3 hours to perform a safe insulation resistance test.

Most manufacturer warranties cover the cost of the replacement unit itself, but not the labour or “call-out” fees for a technician to remove the old one and install the new one. We can assist in processing your claim and provide a clear upfront quotation for the labour involved.

Inverters are electronic devices that generate heat while working. If they are in direct sunlight, they can’t cool down effectively, which significantly shortens the life of the internal capacitors. If your inverter is poorly located, we may recommend relocating it to a shaded area during a replacement.

If the manufacturer has gone bust, we generally cannot source proprietary internal parts. In these cases, we usually recommend upgrading to a modern, high-efficiency inverter with a fresh 10-year warranty, such as a Fronius, Sungrow, or SMA unit.

We offer same-day quotes for inverter replacements. If the unit is a standard model we have in stock, we can often have your system generating power again within 24 to 48 hours.
