List the equipment you want to run
Include quantity, running watts where known, daily operating hours and any loads that must remain on during an outage. Photos of appliance labels can be useful for the assessment.
Explain your backup expectations
Separate “powering everything” from “keeping essentials on”. Discuss whether your priority is daytime energy use, night-time backup or a particular business-critical load.
Share existing-system details
If you already own an inverter, batteries or panels, gather model numbers and installation documentation. Do not assume new components will be compatible.
Plan safe property access
Discuss roof access, shading, proposed equipment space, landlord permission where relevant and any restrictions on installation work. A structural or specialist assessment may be needed.
Ask about the output of the assessment
Clarify any visit fee, what will be checked, what documentation you will receive and what assumptions remain provisional. A useful next step is an itemised proposal with clear inclusions and exclusions.
Continue planning
Estimate your appliance energy use, explore the system components, or prepare an enquiry.
