Selecting exact models, checking compatibility, MOQ, datasheets and destination-market documents.

What role does Rongkai play in a solar project?
Rongkai helps international buyers and project teams turn an energy requirement into a clearer equipment and delivery scope. We coordinate PV modules, inverters, battery storage, mounting systems and related accessories, then help align the relevant model information, documents and delivery inputs. The exact manufacturer, model, document scope and commercial terms are confirmed for the specific project or order.
Which solar products can you source in one order?
We can coordinate modules, on-grid, hybrid and off-grid inverters, battery storage, mounting structures and balance-of-system accessories. A mixed order is only confirmed after model availability, MOQ, packaging and shipment compatibility have been checked.
How do I make sure a document matches the product I want to buy?
Use the exact model number, not only a series name or power rating. Confirm the document revision, voltage configuration, grid version, connector or battery interface, and destination-market scope before placing an order or submitting documents to an authority.
Can you confirm whether modules, inverters and batteries are compatible?
We can help collect the relevant specifications, but final system compatibility must be checked against the exact electrical design and the manufacturer instructions. Share the full BOM, site application, voltage, battery configuration and destination grid requirement for review by a qualified installer or engineer.
Which certificates are needed for my destination market?
Requirements vary by country, product type and project. IEC, CE, TUV, UN38.3, MSDS and test reports are not interchangeable and do not automatically satisfy every import, grid-connection or tender requirement. Send your destination country and required standard before quotation so we can check the available model-specific documents.
Where can I find datasheets, manuals and published certificates?
Use the Downloads centre to search the current official brand documents by model, series or document name. If a required file is not published there, send the exact model, document type and destination market so we can help verify the current applicable document.
Is there a minimum order quantity (MOQ)?
MOQ depends on the manufacturer, model, packaging and shipping method. For a mixed-container or multi-SKU order, each line must still meet its packaging and supplier requirements. We confirm MOQ and any consolidation constraints in the quotation rather than assuming one rule applies to every product.
