Frequently Asked Questions
Common questions from installers, distributors and EPC contractors evaluating Treasol as a photovoltaic connection product supplier.
Is Treasol a PV connector manufacturer?
Yes. Treasol is the solar connection product brand of Dongguan Treasun New Energy Technology Co., Ltd., a photovoltaic connector manufacturer established in 2009 in Dongguan, China.
Our manufacturing operations cover product development, molding, connector assembly, cable processing, wiring harness assembly, inspection and testing.
What photovoltaic products does Treasol manufacture?
Treasol manufactures PV cable connectors, panel connectors, branch connectors, fuse connectors, diode connectors, PV junction boxes and solar wiring harness assemblies.
Electrical ratings, cable sizes, protection levels and certification scopes vary by product model. Customers should evaluate the technical specifications of the exact model required for their application.
Are all Treasol products TÜV- or UL-certified?
No. Not every product model or configuration carries the same certification.
Depending on the specific model and configuration, available documentation may include TÜV Rheinland or UL certification, a CE Declaration of Conformity and RoHS compliance documentation.
Before ordering, customers should confirm the exact product model, electrical rating, cable range, certificate number and applicable certification scope.
What quality inspections are performed on Treasol products?
Treasol applies quality control procedures from incoming materials through production and final inspection.
Depending on the product model and applicable requirements, inspections may include contact resistance, dielectric withstand voltage, electrical performance, insertion and withdrawal force, locking performance, pull-out or tensile performance, environmental testing and final product inspection.
Testing requirements vary according to the product specification and certification scope.
Does Treasol provide OEM and customized PV connection solutions?
Treasol can evaluate OEM and customized requirements for connector configurations, solar cable assemblies, wiring harnesses, product labeling and packaging.
Feasibility depends on the technical requirements, order quantity, tooling requirements and applicable certification scope. Changes to materials, dimensions, cables or assembly methods may affect whether an existing certification remains applicable.
Can I order samples, and what is the MOQ?
Sample availability, MOQ, sample cost and lead time depend on the product model, configuration, certification requirements and packaging.
Standard connectors may have different requirements from customized cable assemblies or OEM products. Please provide the required model, estimated quantity and destination country so that our team can confirm the applicable commercial terms.
What information is required for a quotation?
For an initial quotation, please provide:
- Product model or intended application
- Cable size
- Estimated quantity
- Destination country
If available, you may also provide the required voltage and current, certification, mating connector information, connection configuration and required delivery date.
These details help us confirm the appropriate product configuration, documentation and commercial terms without requesting unnecessary information. Contact Our Team
Does "MC4-compatible" mean the connector can be mated with any MC4-type connector?
No. Physical fit, an MC4-type interface or matching voltage and current ratings do not by themselves establish cross-brand mating compatibility.
The exact connector models, manufacturer documentation, mechanical interface, cable compatibility, certification scope and project requirements should be verified.
Where no approved cross-brand mating combination is documented, use a verified mating pair from the same manufacturer. Read our PV Connector Compatibility Guide
