Solar System Repairs Coomera, Gold Coast: HVAC Tripping Fix

Power Issues After an Install? Expert Solar System Repairs in Coomera

Is there anything more frustrating than upgrading your home with new technology, only to have it break something else? You invest in a solar battery to save money and gain independence, but suddenly your air conditioning won’t stay on. It turns an exciting upgrade into a daily headache.

This “ripple effect” of electrical faults is all too common when new systems are integrated into existing switchboards. Recently, Fallon Solutions was called to a property in Coomera to assist a resident who was caught in a power struggle. A solar battery had been installed just days earlier by another company, and ever since, the power to their HVAC (Heating, Ventilation, and Air Conditioning) system kept cutting out.

If you are facing a problem with solar system integration or nuisance tripping after an install, you need an expert who understands both solar and general electrical work to untangle the mess.

The Problem: The “Blame Game” and Persistent Tripping

The homeowner in Coomera reached out to us with a timeline that clearly pointed to the new installation as the culprit. “Solar battery installed on Tuesday… since then the switch for the HVAC has been tripping.”

The original installer had returned to the site to attempt a fix. Their solution was to simply replace the safety switch, assuming the switch itself was faulty. However, the power continued to trip.

This is a classic scenario of treating the symptom, not the cause.

Why does this happen? When a high-powered device like a solar battery inverter is added to a switchboard, it changes the electrical dynamics of the home.

• Nuisance Tripping: Solar inverters can generate high-frequency electrical “noise” or minor earth leakage. If the existing safety switches (RCDs) on other circuits (like the air con) are sensitive or incompatible with this new load, they will trip repeatedly.
• Wiring Disturbances: The installation process involves moving wires behind the switchboard. A loose neutral wire or a pinched cable caused during the install can create intermittent faults.
• Incorrect RCD Types: Modern solar batteries often require specific “Type B” or “Type F” RCDs. If the installer uses a standard household switch, it may not cope with the DC leakage currents from the battery.

The customer was left with a battery that worked, but a home they couldn’t cool down—a major issue in the Coomera heat.

The Solution: Solar Fault Finding and Rectification

Upon arrival, our Clean Energy Council (CEC) accredited electrician conducted a comprehensive solar check to bridge the gap between the new battery and the existing electrical system.

Since the original installer’s “quick fix” of swapping the switch failed, we knew we had to look deeper. Here is how we approached the solar system repairs:

1. System Isolation and Safety Check: We isolated the new battery system and the HVAC circuit to ensure the site was safe.
2. Insulation Resistance Testing: We used a Megger tester to check the cabling of the HVAC circuit. This tells us if there is actual damage to the wiring insulation causing the trip, or if it is an equipment conflict.
3. RCD Analysis: We inspected the type of safety switch controlling the HVAC and the battery. We identified that the interaction between the battery inverter and the HVAC circuit was causing an imbalance.
4. The Repair: We reconfigured the switchboard layout to separate the circuits effectively and installed the correct class of protection device that could handle the specific load characteristics of the home.
5. Load Testing: We ran the HVAC system at full power while the solar battery was charging and discharging.

We confirmed that the system held stable with no further tripping.

By diagnosing the root cause—electrical incompatibility—rather than just swapping parts, we resolved the conflict between the two systems.

The Benefits for the Homeowner

Getting a third-party expert to perform a solar repair on a botched install offers significant relief:

• Restored Comfort: The air conditioning is back online, which is essential for comfort in Queensland.
• System Safety: Constant tripping is bad for electrical appliances. Fixing the fault protects the expensive HVAC compressor from damage caused by hard shutdowns.
• Accountability: We provided a clear report on what went wrong, giving the homeowner peace of mind that the issue was technical, not just “bad luck.”

Reliable Solar Storage: The homeowner can now enjoy the benefits of their new battery without sacrificing other home comforts.

Why Choose Fallon Solutions?

One of the biggest risks with solar is that many installers are “solar only” and may lack deep experience in general domestic electrical fault finding. Conversely, general electricians might not understand the complexities of battery inverters.

At Fallon Solutions, we are both. We are Master Electricians and accredited solar installers. This dual expertise makes us the perfect choice for solar fault finding. We understand how a new battery affects your old switchboard, and we have the skills to make them work in harmony. We fix the problems that others leave behind.

Don’t Let The Upgrade Become a Downgrade

Upgrading to solar storage should be a seamless experience, not a trade-off between power and comfort. If a recent installation has caused electrical gremlins in your home, don’t let the installer tell you “it’s a coincidence.”
