Can I add a battery to my existing solar system?

Potentially, The answer depends on your existing solar system, electrical infrastructure, equipment and energy requirements. An assessment is needed to determine whether battery storage can be appropriately integrated with your existing setup.

Do I need to replace my existing solar system?

Not necessarily. An existing system may still be suitable for continued use or upgrading. The right approach depends on its configuration, condition, capacity and how your electricity requirements have changed. We assess the existing system before recommending an approach.

My solar works during the day but I still have high bills at night. Can you help?

Yes. This is one of the situations where a solar and battery upgrade assessment can be useful. If your solar generates electricity during the day but your property consumes significant electricity after sunset, battery storage may be one option worth investigating.

Can I upgrade an older solar system?

Potentially. Older systems can vary significantly, so the system needs to be assessed before determining whether an upgrade is appropriate. Depending on the circumstances, the right approach could involve additional equipment, battery storage, electrical work or replacement of some components.

Can you assess my existing solar system?

Yes. Oz Home Energy can assess suitable existing solar systems as part of a solar and battery upgrade enquiry.

How do I know if a battery is suitable for my existing solar?

Your electricity consumption and solar generation are important factors. If you export significant solar during the day and consume electricity later in the evening, battery storage may be worth investigating. A recent electricity bill can provide useful information for an assessment.

Will a battery eliminate my electricity bill?

No specific result should be assumed. The outcome depends on your solar generation, electricity consumption, battery capacity, usage patterns and grid electricity requirements. Oz Home Energy does not publish unsupported savings guarantees.

What size battery do I need?

Battery capacity should be considered in relation to your energy use and existing solar system. A larger battery is not automatically the right solution. The appropriate capacity needs to be assessed based on your circumstances.

Can I add an EV charger to my existing solar and battery system?

Potentially. An EV adds another electricity load to the property, so the existing solar, battery and electrical infrastructure should be considered together. Oz Home Energy can assess EV charger requirements as part of a broader energy upgrade.

Switchboard Upgrades

Switchboard Upgrades Sydney - Safer Electrical Infrastructure for Your Home or Business

Lower energy bills start here.

Your switchboard is at the centre of your property's electrical system. When you add significant electrical equipment such as solar, battery storage or an EV charger, the existing switchboard may need to be assessed to determine whether it can support the new requirements.

Oz Home Energy provides switchboard upgrades in Sydney for suitable residential and commercial properties.

We are a licensed NSW electrical contractor — Licence 382607C — with an installer-led approach focused on safety, reliable workmanship, practical recommendations and reasonable pricing.

A switchboard upgrade is not automatically required just because you are installing new electrical equipment. The existing switchboard and proposed electrical load need to be assessed first.

Our goal is simple: understand what your property needs, explain the options clearly and carry out the required electrical work properly.

Start Your Energy Assessment

What Is a Switchboard Upgrade?

A switchboard upgrade involves modifying or replacing components of an existing electrical switchboard to better suit the electrical requirements of a property.

The switchboard distributes electricity throughout your property and incorporates protective electrical equipment.

Over time, a property's electricity requirements can change significantly.

A home that once had relatively modest electricity consumption may now have:

Air conditioning
Multiple major appliances
Solar Battery storage
An EV charger
Additional circuits
Home office equipment
Other significant electrical loads

Commercial properties can experience even larger changes as businesses add equipment, expand operations or introduce new energy systems.

An assessment determines whether the existing switchboard is suitable for the proposed work and whether an upgrade is required.

Signs Your Switchboard May Need Attention

You Are Planning a Major Electrical Upgrade

If you are adding solar, batteries, EV charging or other substantial electrical equipment, your switchboard should be considered as part of the project.

Your Switchboard Is

Older

An older switchboard may warrant assessment, particularly if you are planning additional electrical work. Age alone does not determine whether an upgrade is required.

Reduce Reliance on Grid

Electricity

Generating electricity at your property can reduce the amount of electricity you need to purchase from the grid when your solar system is producing energy. The actual impact depends on your energy consumption, solar generation and when electricity is being used.

Make Better Use of Your

Roof

Your roof may provide an opportunity to generate electricity directly at your home or business. We assess the property and relevant installation requirements rather than assuming every roof is suitable for the same system.

You Have Limited Electrical Capacity

If your property has increasing electrical demand, the existing infrastructure may need to be assessed.

You Are Renovating

A renovation can introduce new circuits and electrical loads. This can be a suitable time to assess the existing switchboard and broader electrical infrastructure.

Take Greater Control of Energy Costs

Electricity costs are an important consideration for many households and businesses.

Solar can form part of a broader strategy to manage how your property generates and uses electricity.

Build Towards a Broader Energy System

Solar does not necessarily need to be viewed as a standalone project.

Depending on your circumstances, your future energy requirements may include battery storage or EV charging. Considering those requirements early can help you make more informed decisions about your electrical and energy setup.

You Are Unsure Whether Your Switchboard Is Suitable

You do not need to diagnose the problem yourself. If you are planning an electrical or energy upgrade and are unsure whether your switchboard can support it, an assessment can establish the relevant requirements.

Generate Electricity During Daylight Hours

Solar generation occurs when sunlight is available. This can be particularly relevant for homes and businesses that use electricity during the day. Understanding when your property consumes electricity helps determine how useful solar may be for your circumstances.

When Might You Need a Switchboard Upgrade?

An EV charger introduces an additional electrical load to your property. Before installation, the existing switchboard and electrical capacity should be considered. Some properties can accommodate the charger without major switchboard work. Others may require an upgrade.

Solar connects into your property's electrical system. Depending on the existing switchboard and installation requirements, electrical work may be required to accommodate the new system.

Battery storage introduces additional electrical equipment to your property. The existing switchboard and electrical infrastructure need to be considered as part of the installation.

Older switchboards may have been designed around electrical requirements that are very different from those of a modern home or business. That does not automatically mean the switchboard needs to be replaced. An assessment can determine what work, if any, is appropriate.

Your property may have gained new appliances, equipment or additional electrical circuits. If the electrical infrastructure no longer matches the property's requirements, a switchboard assessment may be appropriate.

Understand Why You Need the Upgrade

Tell us what you are planning. It could be an EV charger, solar system, battery, renovation, additional electrical equipment or another project.

Assess the Existing

Switchboard

We consider the existing switchboard and relevant electrical infrastructure. The objective is to understand what is currently installed and how it relates to the proposed work.

Identify the Electrical Requirements

We determine what the proposed new equipment or electrical work requires. This allows the existing infrastructure to be assessed against the new requirements.

Explain the Recommended

Work

If an upgrade is appropriate, we explain the relevant work and why it is required. If an upgrade is not necessary, we can explain that as well.

Provide a Project-Specific

Quote

The quote reflects the actual electrical work required at the property.

Complete the

Upgrade

Once approved, the agreed switchboard work is completed with attention to electrical safety and reliable workmanship.

Review the Completed

Work

The completed electrical installation is checked and relevant information is explained.

Residential Switchboard Upgrades For Sydney Homes

Modern homes can have substantially greater electrical requirements than many older properties were originally designed to accommodate.

Adding solar, battery storage or EV charging can increase the importance of having appropriate electrical infrastructure.

However, a switchboard upgrade should not be recommended simply because a property is old.

The correct approach is to assess the existing switchboard in relation to the work you want to carry out.

Oz Home Energy can assess suitable residential switchboard requirements and explain whether an upgrade is appropriate.

Start Your Energy Assessment

Commercial Switchboard Upgrades

Businesses can have significantly different electrical requirements from residential properties.

Commercial equipment, larger premises, solar systems, battery storage and EV charging infrastructure can all affect electrical demand.

A switchboard assessment can help determine whether existing infrastructure is suitable for proposed commercial electrical work.

For larger projects, submit the project details through our commercial enquiry service.
