Frequently Asked Questions

We service Adelaide and surrounding suburbs. If you are unsure whether your location is within our service area, contact us with your suburb and we can confirm availability.

Yes. Helios Electrical Group is fully licensed and insured for the work we undertake. Our licence and accreditation details are listed in the website footer.

No. You deal directly with people who understand the electrical and installation side of the job. Our recommendations are based around the property, the existing electrical system and what you actually need.

Yes. We carry out residential electrical and energy work as well as selected commercial projects. The scope can range from everyday electrical maintenance through to larger solar, battery, switchboard and EV charging installations.

We carry out lighting, power points, ceiling fans, fault finding, electrical repairs, smoke alarm work, safety upgrades, rewiring and general electrical maintenance.

You can see more on our domestic electrical and maintenance page .

Yes. We investigate problems such as tripping circuits, faulty outlets, lighting faults, intermittent electrical issues and equipment causing protective devices to operate.

Repeated tripping can be caused by a faulty appliance, damaged wiring, moisture, insulation faults, circuit overload or another electrical issue. The protective device should not simply be replaced or bypassed without first finding the cause of the fault.

Yes. We can inspect and repair existing electrical installations where practical. If unsafe or non compliant work is identified, we will explain what needs to be corrected before proceeding.

An upgrade may be worth considering if the board still has older protection, limited capacity, damaged equipment, poor labelling or insufficient room for new loads such as solar, batteries, air conditioning or EV charging.

Yes. We carry out switchboard upgrades including modern RCBO protection, circuit reorganisation, surge protection, additional capacity and preparation for larger electrical loads.

More information is available on our switchboard upgrades page .

Yes. Where the property and network allow it, we can undertake single phase to three phase upgrades and coordinate the electrical work required around the switchboard, consumer mains and new equipment.

Three phase can provide additional capacity for larger loads and may be useful for high capacity solar systems, batteries, EV chargers, large air conditioning systems, workshops and other substantial electrical equipment.

Yes. We design and install solar systems around the property, roof layout, electrical supply, energy usage and future plans rather than applying the same system design to every home.

The right system size depends on your electricity consumption, available roof space, roof orientation, network limitations, daytime usage and whether you plan to add battery storage or larger electrical loads in the future.

Often, yes. Existing inverter capacity, switchboard condition, roof space, network approval and the age and configuration of the current system all need to be considered first.

Yes. If an inverter has failed or an older system needs upgrading, we can assess the existing panels, wiring and system configuration and recommend the appropriate next step.

Lower production can be caused by shading, inverter faults, panel or wiring issues, monitoring errors, dirt, system configuration, export limitations or normal seasonal variation.

If something does not look right, see our solar repairs and fault finding service .

Yes. We install battery storage as part of new solar systems and can also assess existing solar installations for battery retrofits.

Visit our battery storage systems page for more information.

In many cases, yes. The best solution depends on your existing inverter, switchboard, solar system, available installation location, electrical supply and whether you want backup capability.

Battery sizing should be based on how much energy you use, when you use it, how much surplus solar is available and what you want the battery to achieve. A larger battery is not automatically the best option for every property.

Only if the system is designed and installed with suitable backup capability. Some battery installations provide selected backup circuits, while others can be designed for broader or whole home backup depending on the equipment and property.

Yes. There are battery and hybrid inverter systems designed for three phase properties. The correct configuration depends on the existing solar system, loads, backup requirements and available electrical capacity.

Yes. We install EV chargers and assess the existing switchboard, electrical supply, charger location and available capacity before deciding on the appropriate installation.

See our EV charging page for more information.

It depends on your electrical supply, available capacity, whether the property is single or three phase and the charging capability of the vehicle itself.

Some chargers can be configured with suitable monitoring or energy management equipment to make better use of surplus solar generation. Compatibility depends on the charger and existing solar equipment.

Not every installation requires it, but load management can be useful where the available electrical capacity is limited or where larger household loads need to be balanced with EV charging.

You can request a quote through our website contact form, by phone or by email. Providing photos, equipment details and a short description of the work can help us understand the job before arranging the next step.

Some jobs can be estimated from clear information and photos, while others require an onsite inspection before a firm quote can be provided. Larger solar, battery, switchboard and electrical upgrade projects generally require more detailed assessment.

Unless stated otherwise, quotes are generally valid for 30 days. Product pricing, rebates, certificates and equipment availability can change, particularly for solar and battery systems.

A variation may be required if hidden faults, unsafe existing conditions, access restrictions, network requirements or additional work are discovered that could not reasonably have been identified before the quote was prepared.

Yes. Helios Electrical Group provides a 5 year workmanship guarantee, subject to the conditions outlined in our Terms and Conditions.

It covers issues caused directly by our workmanship. It does not cover misuse, weather events, pests, unauthorised alterations, pre existing faults or product failures that fall under a manufacturer's warranty.

Manufacturer warranties apply to the individual products supplied. Where appropriate, we can assist with diagnosing the issue and navigating the warranty process.

Contact us with a description of the issue, the property or job details and any relevant photos or fault information. We will review the situation and advise the appropriate next step.
