Give the exact solar component model, labelled electrical ratings, connector type, dimensions, and included parts. Photograph the specification plate and keep the maker's documentation with the stock record rather than estimating performance from appearance.
Compatibility depends on the full system, not a single voltage or plug. Ask buyers to confirm design with a qualified installer, and compare connectors and ratings against the equipment they already use before describing a match. Keep any adapters visible and state when they are not included in the offer. Check the unit for transit damage before listing, and distinguish tested output from a specification printed by the manufacturer.
Do not promise household output, savings, or system compatibility from a component listing. Disclose any test limits, retain supplier evidence, and check relevant standards or safety requirements before offering a unit with uncertain origin or ratings.
