We service non-grid-tied DC-AC inverters and selected drive/industrial and marine inverter-chargers. If unsure, send the model number and a photo of the rating label.
- No AC output or intermittent output
- Unit trips, fault codes or beeping
- Overheating, fan not running, thermal shutdown
- Electrical noise, hum, or burning smell
- Blown fuses, GFCI/RCD nuisance trips
Tip: If the inverter has failed, avoid repeated power-on attempts—this can worsen damage.
Every repair starts with structured intake and visual inspection. We test power stages, drivers and control boards, then verify under load with thermal soak. Safety and performance are checked to manufacturer specs where available.
- Intake: model/serial capture, visual inspection, isolation and safety checks
- Component-level diagnostics: MOSFETs/IGBTs, gate drivers, rectifiers, capacitors, transformers
- Control & protection: sensors, feedback loops, firmware fault paths
- Full-load bench test: resistive/inductive loads, waveform and ripple analysis
- Report: findings, parts replaced, test results, warranty
Standard diagnostics in 2–5 business days depending on queue and parts availability.
We replace failed semiconductors and passives with quality parts, address thermal issues, and reinforce weak points identified across models.
Indicative pricing (AUD):
- Diagnostics & quote: $120–$180 (credited against approved repairs)
- Typical DC–AC inverter repairs: $220–$650 + parts
- Drive/industrial inverter modules: $380–$980 + parts
Standard turnaround: 5–10 business days after approval. Priority service available on request. All repairs include bench test results and a 90‑day warranty on replaced parts and workmanship.
Online-only service. Please ship your inverter after receiving confirmation. Include: contact details, symptoms, accessories (if relevant), and safe packaging.
