Solar Inverter Replacement Camp Hill, Brisbane: System Fixed

Power Conflict: Solar Inverter Replacement in Camp Hill

Is there anything more frustrating than upgrading your home with new technology, only to have it break your existing systems? You buy an electric vehicle to save on petrol, install a charger at home, and suddenly realise your solar panels—the very things meant to power the car—have shut down.

This “tech conflict” is becoming increasingly common as our homes become smarter and more electrically complex. Recently, Fallon Solutions was called to a property in Camp Hill where a resident was facing this exact dilemma. Their solar system, originally installed by another company, had completely stopped working just one week after a new EV charger was installed.

If your solar system has gone silent after recent electrical work, it’s not a coincidence. Here is how we diagnosed the fault and performed the necessary upgrade to get the power flowing again.

The Problem: When New Tech Breaks Old Solar

The homeowner in Camp Hill contacted us with a clear timeline of events: “Check the Solar System – stopped working last week after the EV charger was installed.”

When an Electric Vehicle (EV) charger is installed, it places a significant new load on the home’s electrical switchboard. If the existing solar inverter is older, or if the wiring configuration isn’t perfectly balanced, the sudden change in electrical demand can cause the inverter to trip, fault, or fail completely.

Signs You Need a Solar Inspection:

• Red Fault Lights: The inverter displays a red light or an error code immediately after other electrical work is done.
• Blank Screen: The inverter display is completely dead during the day.
• Zero Production: Your electricity bill spikes because you are charging your car from the grid, not your roof.
• Orphaned System: In this case, the system was “installed by another company.” This is a common pain point; if the original installer is gone or refuses to fix compatibility issues, the homeowner feels stranded.

The customer needed an expert to check solar performance and determine why the two systems weren’t playing nicely together.

The Solution: Upgrading to a 5kW Sungrow Inverter

Upon arrival, our Clean Energy Council (CEC) accredited electrician conducted a thorough solar fault finding process. We needed to confirm whether the issue was a simple wiring error or a hardware failure.

The diagnosis confirmed that the existing inverter had failed and was no longer compatible with the site’s requirements. To fix this, we proceeded with a complete solar inverter replacement.

Here is how we executed the repair:

1. Safety Isolation: We isolated the DC power from the roof and the AC power from the grid to ensure a safe working environment.
2. Removal of Faulty Unit: We disconnected and removed the failed inverter that had been installed by the previous company.
3. 3-Phase Upgrade: The home was operating on 3-phase power (common in homes with ducted aircon or EV chargers). We installed a new 5kW 3-phase Sungrow inverter.
   • Technical Note: A “3-phase” inverter balances the solar power across all three live wires coming into the house. This is crucial for stability when high-draw appliances like EV chargers are running.
4. Grid Connect Setup: We configured the inverter for “grid connect.” This ensures that once the home and the car have used the solar energy they need, any excess power is automatically sent back to the grid for a feed-in tariff credit.
5. Commissioning: We powered up the system, synced it with the grid, and verified that it was generating 5kW of clean energy, ready to charge the EV.

The Benefits for the Homeowner

Opting for a high-quality solar inverter replacement rather than trying to patch up an incompatible unit offers significant benefits:

• Energy Independence: The homeowner can now charge their EV using free power from the sun, rather than paying for grid electricity.
• System Stability: The new Sungrow inverter is designed to handle the electrical load of a modern home, reducing the risk of future trips or faults.
• Warranty Protection: A brand new inverter comes with a fresh manufacturer’s warranty, providing peace of mind that the old “orphaned” system couldn’t offer.
• Smart Monitoring: Modern inverters often come with app connectivity, allowing the user to see exactly how much power is going to the house, the car, and the grid.
