Existing System Upgrades

Improve, expand or modernise your existing energy system

Your current solar, battery or backup-power system may be able to support additional capacity, newer equipment or improved system performance without starting again from the beginning.

Battery-capacity expansion
Inverter and equipment replacement
Additional solar generation
Upgrade Potential Retain what still works and improve the components limiting your current system
Existing system Review, retain, replace or expand

Not every component needs replacing

Existing equipment can first be considered for condition, capacity and compatibility with the proposed upgrade.

Upgrade Options

Different ways an existing system may be improved

The right upgrade depends on the current equipment, system capacity, property requirements and the specific limitation you want to address.

01

Add battery capacity

Additional compatible battery storage may extend backup duration, support more essential equipment or retain more energy for later use.

Discuss battery expansion
02

Replace or upgrade the inverter

A newer or larger inverter may be considered where the current unit is ageing, undersized, incompatible or limiting the wider system.

03

Expand solar generation

Additional panels may increase daytime generation where suitable space, inverter capacity and the existing installation allow it.

04

Improve control and performance

Monitoring, system configuration, circuit planning and supporting equipment may help improve how the complete installation operates.

Existing System Review

Your requirements may have changed since the original installation

Increased electricity usage, new appliances, business growth or longer backup requirements can place demands on a system that was designed for an earlier need.

When an Upgrade May Help

Common reasons customers consider changing an existing system

01

Backup time is no longer sufficient

The batteries may no longer support the required appliances or expected backup duration.

02

Electricity usage has increased

New appliances, equipment or operating requirements may exceed what the original system was designed to support.

03

Existing equipment is ageing

Older batteries, inverters or supporting components may no longer provide the required performance or reliability.

04

More solar energy is required

The property may have additional space and a greater need for daytime generation than when the system was first installed.

What We Consider

The existing system needs to be understood before changes are made

Upgrade potential depends on more than the individual component. The wider system, property demand and compatibility requirements should also be considered.

Current Equipment

Models and specifications

Inverter model, battery type, panel capacity, control equipment and installation information can all affect the possible upgrade.

System Demand

Usage and essential loads

The appliances, equipment and circuits that need support help determine the additional capacity or equipment required.

Compatibility

How the components work together

Voltage, communication, capacity, battery chemistry and manufacturer requirements can influence whether components can be combined.

Homes and Businesses

Upgrade support across residential and commercial systems

Existing systems can face different limitations depending on the property, equipment demand and how energy is used during the day.

Residential Systems

Improve backup and solar capacity at home

Household systems may need additional storage, greater solar generation or newer equipment as electricity usage changes.

  • Longer backup duration
  • Support for additional appliances
  • More daytime solar generation
  • Replacement of ageing components
Commercial Systems

Expand capacity as business requirements grow

Commercial systems may need to support longer operating hours, additional equipment, site expansion or higher essential loads.

  • Additional battery capacity
  • Expanded commercial solar generation
  • Higher inverter capacity
  • Equipment and control improvements
Help Us Understand Your System

Send the right details with your upgrade enquiry

Existing-system enquiries are easier to review when the current equipment and the desired outcome are clearly explained.

01

Equipment photographs

Include clear photographs of the inverter, batteries, panels, distribution equipment and visible product labels.

02

Model numbers and capacities

Share the model numbers, battery capacity, inverter rating and solar-panel information where available.

03

Current system limitation

Explain whether the concern is backup duration, generation, capacity, equipment age or another performance issue.

04

Desired upgrade result

Tell us what additional appliances, circuits or operating requirements the upgraded system needs to support.

How It Works

From your current system to a suitable upgrade direction

The process begins with understanding what is installed, what is no longer meeting your needs and what you want the upgraded system to achieve.

01

Send the system details

Share photographs, model numbers, current capacity and a description of the required improvement.

02

The current setup is reviewed

Existing equipment, system capacity and potential compatibility limitations are considered.

03

An upgrade direction is identified

Components that may be retained, replaced or expanded can then be identified and quoted.

04

The upgrade moves forward

Equipment supply and upgrade arrangements can proceed once the recommended approach is accepted.

Compatibility must be confirmed before adding or replacing equipment

A component with the correct capacity is not automatically compatible with every inverter, battery, control system or existing installation.

Frequently Asked Questions

Common questions about existing system upgrades

Send us the current equipment details for assistance with a system-specific upgrade enquiry.

Ask About an Upgrade
Can batteries be added to my existing system?

Additional batteries may be possible, but the existing inverter, battery type, voltage, communication requirements and current configuration first need to be considered.

Can more solar panels be added?

Additional panels may be possible where the inverter, existing solar configuration, roof space and wider installation support the proposed increase.

Can the inverter be replaced without replacing everything?

It may be possible to retain compatible batteries, panels or supporting equipment. The existing components and proposed inverter first need to be considered together.

Can you help if another company installed the system?

You can still submit the existing equipment details, photographs and upgrade requirement for review. The possible next step will depend on the condition and configuration of the current system.

What photographs should I send?

Include clear photographs of the inverter, batteries, product labels, distribution equipment, solar panels and the wider installation area where possible.

Do you assist with commercial system upgrades?

Yes. Commercial systems can be considered around operating hours, critical equipment, current capacity and future growth. Visit our commercial solutions page for more information.
