What to expect on the day

Qualified electricians, safe roof access, photos on request, and a clear explanation of your options. We’ll handle DNSP paperwork where required and reconnect monitoring so you can track performance.

Quick checks you can do before we arrive

  • Main switch (solar): In your switchboard, ensure the Main Switch (Solar Supply) is ON. If it trips again immediately, leave it OFF and book a visit.
  • PV array DC isolators: Check rooftop/adjacent DC isolators are ON (handles fully engaged). Do not operate damaged or heat-affected isolators.
  • Inverter screen/lights: Note any flashing lights or messages. Many inverters show Standby/Wake up for a few minutes after sunrise—this is normal.
  • Breakers & RCDs: In the switchboard, confirm inverter AC breaker and any RCDs are ON. If a device won’t reset, leave it and contact us.
  • Wi-Fi & apps: If monitoring is offline, power-cycle your modem/router. Reconnect the inverter to Wi-Fi using its app or WPS (if available).
  • Meter issues: If your meter shows export limiting or grid fault, take a photo—this helps us diagnose DNSP-related issues.
  • Weather & shading: Low output on cloudy days and heavy shade is expected. Compare with a recent sunny day before assuming a fault.
  • After outage: Following a blackout, inverters may take 1–5 minutes to reconnect while they test grid voltage/frequency.
  • Safety first: If you smell burning, see heat damage, or water ingress, isolate the system (turn OFF solar main switch) and call us.

When to book a breakdown visit

  • Inverter shows a persistent fault/error message
  • Repeated tripping of solar breakers/RCDs
  • Production near zero on multiple sunny days
  • Physical damage or suspected water ingress
  • New noises/smells or signs of overheating

Service & Maintenance — FAQs

How often should panels be cleaned?
Most homes benefit from cleaning every 12–24 months. Coastal, rural or high-dust sites may need more frequent soft-wash cleaning to maintain yield.
Will cleaning void my warranty?
No—when done correctly. We use soft-wash methods and avoid harsh chemicals or abrasive pads that can damage coatings.
What’s included in a System Check?
Electrical safety tests, open-circuit/operating voltage checks, inverter diagnostics, array/roof inspection, performance assessment vs. system size, and Wi-Fi/app setup (if applicable). You’ll receive findings and guidance.
What if parts are needed during an Emergency Breakdown?
The fixed call-out covers fault finding and making the site safe. If replacement parts (panels, inverter, isolators, batteries) are required, we’ll provide a clear quote and timeframes.
Common inverter error types to look for
  • Grid faults: over/under-voltage, over/under-frequency
  • Isolation/earth faults: “PV isolation low”, “Insulation resistance low”
  • GFCI/RCD faults: leakage current detected
  • Relay/self checks: “Relay check fail”, “Self-test failed”
  • DC faults: “DC bus over-voltage”, “String mismatch”
  • Temperature: “Over-temperature”, fan failure
  • Communication: “No Grid”, “Meter/CT comms error”, “Wi-Fi offline”
Wording varies by brand/model—note the exact message and we’ll handle the rest.
