It depends on your energy usage, how much excess solar you currently export, and your evening consumption. Households that use a lot of power after sunset and have strong daytime generation tend to benefit most, since a battery lets them use their own energy instead of buying it back. During the consultation we review your usage so you can decide whether storage makes sense for your situation before committing. Battery rebates can change the numbers: eligible installs may qualify under the federal Cheaper Home Batteries Program and the WA Residential Battery Scheme.
In most cases, yes. Whether a solar battery integrates smoothly depends on your current inverter. Some systems support battery add-ons directly, while others need a hybrid inverter or a separate battery inverter to manage charging and discharging. We check compatibility during the on-site assessment and recommend the most practical approach for your existing panels and equipment. A DC coupled battery connects on the solar side of a hybrid inverter, while AC coupling connects on the household side, and we confirm which suits your system on site.
Most residential battery installations are completed within a single day, though this varies with system complexity and whether inverter changes are needed. The work includes mounting the battery, wiring, integration with your solar setup, and commissioning. Power interruption is kept brief, and we test everything before handing over and showing you how the system runs.
Modern solar batteries need very little day-to-day attention, but periodic checks help maintain performance and catch issues early. We recommend keeping the unit clear of obstructions, monitoring charge behaviour through the app, and arranging occasional health checks. Regular maintenance ensures connections stay sound and firmware is current, keeping your stored energy reliable over the system’s lifespan.
Only if it is set up for backup, which not all installations include by default. When configured for backup power, the battery supplies essential circuits during a grid outage, keeping key appliances running. The capacity you have and how it is wired determine what stays powered and for how long. Let us know if outage protection matters and we will factor it into the design.
The right size depends on your evening energy use, how much surplus your panels produce, and whether you want backup capability. Oversizing wastes money on energy storage you never fill, while undersizing means you still draw from the grid at night. We assess your usage patterns and solar output to recommend a capacity that balances cost against how much energy you can realistically store and use.
The main factors are the battery’s storage capacity in kWh, whether your existing inverter can work with a battery or a hybrid inverter is needed, and how much switchboard or backup wiring is involved. Where the battery is installed and how far it sits from the switchboard also matter. We assess these on site and give you a written quote before any work is booked.
