Not sure where to start? Talk to our team
Understand your quote
What affects your battery quote?
Explore five factors that shape the system we recommend.
01 / Battery size
Start with how much energy you use after sunset.
Your evening usage, solar generation and backup goals help determine suitable storage capacity.
- Evening usageHow much electricity you use after sunset.
- Solar generationHow much surplus solar may be available to charge the battery.
- Backup goalsWhich appliances you want to support during an outage.
Battery capacity is one part of the overall system design.
02 / System connection
How the battery connects affects the equipment required.
A hybrid system and an AC-coupled battery connect differently. The appropriate approach depends on your existing equipment and the proposed system.
- Hybrid approachCombines solar and battery management through compatible equipment.
- AC-coupled approachMay allow storage to work alongside an existing solar inverter.
- Installation requirementsCabling, controls and backup equipment depend on the design.
We assess the connection approach for your particular system.
03 / Existing inverter
Your current inverter helps shape the upgrade.
Its model, age and compatibility influence whether it can remain or whether different equipment is needed.
- Model and compatibilityCheck the exact inverter and supported battery options.
- Age and conditionConsider the existing equipment as part of the upgrade.
- Upgrade approachAssess retention, replacement or a suitable AC-coupled solution.
A clear photo of the inverter’s model label can help our team assess options.
04 / Single or three phase
Your electrical supply influences the system design.
Single-phase and three-phase homes have different design considerations, particularly when planning backup.
- Supply typeConfirm the property’s electrical connection.
- Equipment selectionMatch the proposed inverter and battery system to the property.
- Backup coverageAssess which circuits and phases the design can support.
Our team can help identify your supply type; do not open electrical equipment.
05 / Backup needs
Decide what you would like to keep running.
Backup capability depends on the selected equipment, system design and available stored energy. It is not included automatically with every battery.
- Priority appliancesIdentify essentials such as refrigeration, lighting and communications.
- Power requirementsConsider running demand and appliance starting loads.
- Backup durationDepends on usable stored energy and what is operating.
Whole-home backup requires a specific assessment and is not guaranteed.

Straightforward answers
Your battery questions, answered.
A few practical things to know before choosing a system.
Still have a question?
Talk to our teamOften, yes. The suitable approach depends on your inverter, existing solar system and the battery you choose. Our team can assess compatibility and whether an upgrade is needed.
Only if the system includes suitable backup equipment and is configured for backup operation. The appliances it can support and how long they can run depend on the system design, available stored energy and electricity demand. Not every battery installation includes backup.
The right capacity depends on your electricity usage, when you use it, available solar generation and backup goals. A recent electricity bill and information about your current solar system help our team assess suitable options.
Service life varies with the battery model, usage, operating conditions and care. Manufacturer warranties may specify years, cycles, energy throughput and retained capacity. We can explain the terms for the system you are considering.
Follow the manufacturer’s instructions, keep the surrounding area clear and monitor any alerts. Arrange qualified support for faults or servicing, and do not open the battery enclosure or work on electrical connections. Requirements vary by system.
Our team will contact you to discuss your usage, existing equipment and goals. We may request a recent electricity bill or equipment photos before recommending options and confirming any assessment needed.
No. Battery installation should be carried out by a qualified professional for safety and correct performance. Incorrect installation can damage the battery and may void the warranty.
Our qualified technicians fit and test the battery, connect it correctly to your panels and inverter, and guide you through the approval process with your energy retailer.
