Panels alone do not establish backup capability
Outage operation depends on the inverter, storage, switching arrangement and system design. Confirm which circuits the proposed system will actually support during a grid interruption.
Discuss the essential circuits
State what you need to keep running and what can wait. Heavy starting loads, refrigeration and air conditioning need specific assessment rather than an assumption based only on an inverter class.
- Confirm essential and excluded circuits.
- Ask how recharging works between outages.
- Discuss safe operation and changeover with the installer.
- Keep the handover instructions accessible.
