No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.

System decision

Australian system fit

Only exact, manufacturer-named Australian paths are shown. A shared brand, product family or output rating is not proof of compatibility.

Evidence state

Exact pairing not recorded

Exact pairing not recorded

No exact manufacturer-named inverter, battery or integrated-system pairing is recorded for Australia. This is a documentation state, not a finding that the product cannot be used in a system.

A documented relation does not establish site sizing, network approval, protected-load design, firmware state or installer acceptance. When no exact relation is recorded, compatibility remains unestablished in this catalogue.

Before you buy

Two things to check

Local positionUse a market view to check local availability, approvals and warranty scope.

Ask the installer: Will the exact Sunny Boy Smart Energy 5.0/6.0 model satisfy the site phase, array, MPPT, export-control and local grid requirements?
