What is a SAJ home battery?
A SAJ home battery stores electricity for use when you need it, as part of a compatible solar and electrical installation. In a solar home, it can capture available generation that exceeds daytime consumption and supply stored energy when solar output falls.
A complete SAJ installation brings compatible storage, power conversion and control equipment together. The selected components determine charging, discharge and the available backup arrangement.
For your installation, consider the battery, inverter, monitoring and backup arrangement together. A capacity label alone does not explain how the whole system will perform.
Choose a SAJ system by model, capacity and installation scope
SAJ battery enquiries can involve several components. The battery stores energy; compatible inverter and control equipment determine how that energy interacts with your solar panels, home and electricity supply.
Ask ADS Solar to identify the exact product series and model numbers. A family name or rounded capacity label is not enough to establish compatibility, output or backup capability.
Battery configuration
Confirm the module count, nominal capacity and usable energy. Ask whether the proposed arrangement supports future expansion and under what conditions.
Inverter and controls
Confirm the power rating, electrical phase arrangement and how the equipment connects to your solar. Storage capacity does not establish inverter output.
Backup equipment
Identify any additional equipment and electrical work needed for backup. Ask which circuits and appliances are included in the proposed design.
Different SAJ product series can have different installation requirements. Do not assume battery modules or inverter models are interchangeable. Request the current Australian technical documents for the supplied equipment.
How to choose the right battery size
Start with your evening and overnight consumption, available surplus solar and backup priorities. A large battery can be underused if your solar rarely generates enough excess energy or your household uses little electricity after sunset.
Review actual usage
Use bills and available interval data to understand when your home imports electricity. Seasonal heating and cooling can change the pattern.
Check charging opportunities
Compare daytime solar surplus with the capacity you want to charge. Roof orientation, shading, weather and daytime loads affect what remains.
Allow for backup reserve
Energy held for an outage may reduce what is available for daily use. Discuss the balance between everyday savings and backup duration.
For example, a home using 7kWh overnight has a different storage requirement from one using 17kWh. These are usage examples, not package recommendations. Include losses, operating limits and planned future loads in your assessment.
What can change your SAJ installation price?
Electrical work
A switchboard upgrade, longer cable route or additional protection can change the labour and equipment required.
Existing equipment
Your current solar inverter may need to be retained, replaced or integrated through a different arrangement. Ask the designer to explain the proposed approach.
Backup priorities
Supporting selected circuits and supporting larger household loads can require different configurations. Confirm the equipment and costs before proceeding.
Check my property’s installed priceCan I add a SAJ battery to my existing solar?
Potentially, but compatibility must be assessed first. The assessment should identify whether your existing inverter can remain and which connection arrangement is suitable. A SAJ battery is not a universal add-on for every inverter.
- Inverter model: provide the exact make, model and approximate installation date.
- Solar array: confirm system size, condition and generation history where available.
- Electrical supply: identify single-phase or three-phase requirements.
- Switchboard and location: assess space, access and necessary electrical work.
- Backup goals: identify the circuits you want supported during an outage.
Ask the proposal to explain which equipment stays, what is added or replaced and how the completed system will operate.
Will a SAJ battery provide blackout protection?
A suitably designed SAJ system can provide backup, but performance depends on the compatible inverter, battery configuration, additional equipment and selected circuits. Whole-home backup should not be assumed.
Refrigeration, selected lighting, internet equipment and suitable power points are sensible priorities to discuss. Air conditioning, electric heating, pumps and EV charging can demand much more power.
Energy capacity and output are different
Kilowatt-hours (kWh) measure stored energy. Kilowatts (kW) measure the rate of power delivery. A battery can have charge remaining while the connected appliances exceed the available output.
Request a written list of supported circuits, excluded appliances and phase limitations. Also ask whether, and under what conditions, solar can recharge the system while the grid is unavailable.
How long can backup last?
As a simplified calculation, 10kWh available to a steady 1kW load represents ten hours before losses and system limits. Higher loads use energy faster. Actual duration varies with starting charge, reserve settings and appliance use.
How solar and battery storage work together
Daytime generation
Your solar panels supply available household demand. Excess generation can charge a compatible battery within the system’s limits.
Evening use
Stored energy can supply the home as solar output falls. The grid can still supply electricity when demand exceeds available battery power or energy.
Monitoring and settings
Review the monitoring provided with your selected system. Ask how to interpret energy flows and balance reserve settings with everyday use.
For a complete installation, explore solar and battery packages and residential solar solutions. Compare 6.6kW, 10kW and 13kW solar systems against your roof and energy profile.
Plan for future energy use
Include planned electric cooking, heating, cooling and vehicle charging in the design conversation. Your future demand may differ from the pattern shown on today’s bills.
If you are considering an electric vehicle, explore our EV charging solutions. Charging while solar is generating may suit your routine and reduce the amount of energy that needs to pass through the home battery.
For battery expansion, ask about compatible modules, installation space, inverter limits and the manufacturer’s conditions. Future upgrades require confirmation for the system already installed.
Understand savings, incentives and warranty terms
A battery can reduce purchased electricity when stored solar supplies energy you would otherwise import. The benefit depends on tariffs, export payments, charging opportunities, losses and the amount of battery capacity used each day.
Ask for an estimate based on your bills and total installation cost. A fixed annual saving or universal payback period cannot represent every household.
Confirm any proposed incentive
Your quotation should identify any incentive included in the calculation, its eligibility requirements and any participation conditions. Do not assume every system qualifies or that the same offer applies across all states.
Check product cover and battery performance cover separately
Request the Australian warranty documents for the exact SAJ inverter and battery supplied. A battery performance warranty is different from product warranty cover: their durations, remedies and conditions can differ. Review capacity-retention requirements, operating conditions and claim procedures. Ask separately about installation workmanship coverage and support contacts.
