Product-family photographs are illustrative and may show particular brands or older models. They are not advertisements for stocked items or evidence of authorised OEM distribution. Exact part numbers, product origin, availability and certificates are confirmed only in an actual supplier quotation.
Ask for the approved single-line diagram, modules/inverters, string layout and DC equipment list. DC switching and protection must be verified by qualified engineers.
| Factor | Specification to send | Technical note |
|---|---|---|
| Design voltage | String maximum open-circuit voltage in design conditions | Confirm cold-temperature voltage and equipment ratings. |
| DC protection | Appropriate DC-rated isolation and overvoltage devices | AC-rated switching cannot be assumed suitable on DC circuits. |
| Connectors | Manufacturer mating compatibility, seal and contact | Avoid mixed-brand mating without documented compatibility. |
| Complete BOQ | PV string drawings, module and inverter schedule | Equipment sourcing does not imply engineering design or installation. |
Only when the manufacturer explicitly rates that device and connection arrangement for the relevant DC circuit.
No. Mechanical similarity does not establish approved and safe mating compatibility.
This is material sourcing. Design, certification and installation services must be separately arranged.
Attach a product specification, BOQ or datasheet by email if needed. Provide as many of these details as you have:
