What information does an installer need before selecting a battery system?

Outline — draft for review

1. Start with the supply

• Single phase or three phase, and how it is confirmed rather than assumed.
• Main switchboard arrangement and available space.
• Network and export requirements that apply to the site.

2. The loads the customer actually wants covered

• Everyday consumption versus the loads wanted during an outage.
• Which loads are motor-started, and why that matters to power rating.
• Separating "nice to have" from "must stay on".

3. The physical site

• Where the equipment can be mounted, and the clearances required.
• Cable routes and distances between inverter, battery and switchboard.
• Ambient conditions and anything affecting the location choice.

4. The solar side

• Existing array details, or the planned panel model and quantity.
• Roof orientations, shading and available area.
• Why string design is confirmed by the installer, not the supplier.

5. Compatibility checks

• Matching battery voltage architecture to the inverter.
• Controllers, bases and accessories that are required rather than optional.
• Documentation to request from the manufacturer where anything is unclear.

6. A short pre-enquiry checklist

• The compact list to work through before sending us an enquiry.

Writer's notes: supply-only framing — design, installation and compliance sit with the licensed contractor. No invented compatibility claims; verify against manufacturer documentation. Australian English throughout.
