Solar inverter wholesale suppliers inquiry cards

What a wholesale comparison still has to confirm

Solar inverter wholesale suppliers quotations only line up when the model string, accessory list and delivery place match. Use the cards as starting names. The factory still has to confirm rated AC power, the DC input window, MPPT channel count, phase, grid voltage and the communication protocol for the unit it offers.

Keep each line of a bill of materials separate. A string inverter, a microinverter and a monitoring gateway can share a project and still need different drawings. If one supplier proposes an alternate frame, mark the change in rating, connector, enclosure rating or lead time before you treat the prices as comparable.

Ask for the datasheet and outline drawing of the quoted model. A family brochure, a certificate for a different power class, or a photo of a similar cabinet is not exact-item evidence. Inspection method, serial traceability and the document pack can be named in the brief even when the sample plan is still undecided.

Optional budget text should show the currency and whether the figure is per unit or for the whole order. Choosing high-end, mid-range, budget or undecided tells us which commercial band to request. It does not mean those factories have been scored.

Interconnection studies, structural checks and installation safety remain with the parties qualified for the site. Our role is to collect the requirement and coordinate factory responses. Read the supplier matching steps, the equipment planner, or the procurement brief before you send the quantity and destination.

Public system primers, including the inverter and grid-services overview from the U.S. Department of Energy, are useful for naming fields. They are not an approval list for any factory on this page. Record the test basis beside any efficiency figure a supplier volunteers, and do not copy a brochure percentage onto the comparison sheet until the exact model is identified.
