Direct answer
South Africa combiner box RFQs should state string count, system voltage, protection layout, enclosure IP rating and whether the order includes cable and connectors.
For backup-heavy markets, PV combiner boxes are often part of a wider electrical BOS package, so we review them with DC protection and AC-side needs.
