Specification
Ask each factory to restate rated AC power and the DC input window for the quoted model, including how many MPPT channels are actually offered.

CurrentWorks Procurement helps EPC teams, solar installers, and equipment distributors describe a commercial solar inverter before factories are asked to quote. The desk does not stock inverters, sign interconnection papers, or treat a family brochure as proof for a named model.
A lower headline unit price is not comparable until these four fields describe the same commercial solar inverter request. CurrentWorks Procurement does not publish a savings figure.
An illustrative buyer worksheet might say 100 kW rated AC power, a 600-1000 V operating DC window, 6 independent MPPT channels, and 480 V three-phase. These are draft requirements, not a compatible configuration or test result. Ask the supplier to confirm the inverter’s maximum DC voltage, operating and short-circuit current limits per MPPT, strings per channel, and enclosure rating; the project engineer compares them with the array. Central or string conversion can reduce equipment count, while module-level conversion can support per-module operation and monitoring. The Department of Energy inverter overview explains these architectures without approving a product.
Ask each factory to restate rated AC power and the DC input window for the quoted model, including how many MPPT channels are actually offered.
State units or systems and whether spares, DC disconnects, or communication gateways sit on separate lines.
Align currency, packaging, freight, taxes and duties, warranty basis, and what commissioning is excluded.
Request the datasheet and dimensional drawing for the quoted model. A product-family leaflet does not identify the exact item.
String layout, roof equipment pad, and the AC voltage the building already uses.
Central or string architecture, DC collection, and the enclosure environment at the pad.
Limited equipment space, phase, and how monitoring should report each canopy.
Grid voltage, protocol, and whether a hybrid interface is even in scope.
Open the project-use questions or read the procurement brief.
Name the commercial rooftop, ground-mount, carport, or electrical-room context, then the connection point. A product family label alone does not tell a factory which configuration to price.
Write the required value, an acceptable range, or “open for the quoted model.” Ask the supplier to state the test basis rather than copying a neighboring power class.
No. The desk coordinates quotations. Stock, lead time, and listing status are answers the proposed supplier gives for the exact model.
Optional. Give an amount or range, the currency, and whether it is per unit or for the whole order. Premium, mid-range, budget-friendly, or undecided describes your cost and service priorities, not a verified factory grade. No existing quotation is needed.
Datasheet, outline drawing, and any safety-listing or quality-system file the supplier claims, each tied to the manufacturer and model number. ISO 9001 or a UL/ETL file is evidence to request, not a credential of this desk.
Code review, structural checks, interconnection approval, and safe installation remain with qualified parties. Record every deviation in rating, connector, protocol, or accessories.
Include the application, ratings, quantity, US destination, and requested timing. Drawings can follow after the desk replies. This form does not create a purchase order.
Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements.
