Factory sourcing support for microinverter manufacturers
Buyer notes
Each card is a worksheet. The date is the day the note was posted. It is not a ship date and it is not a test date.
Microinverter notes
A quality-inspection checklist for B2B buyers sourcing solar microinverters — what to verify at the source, what to test on your own bench, and which single step most buyers skip that shows up later as a port delay.

Page numbers on this index end with a slash so a later page stays under the blog path. The author line, when it prints, is the desk that drafted the questions. It is not an inspector stamp. A missing author line means the byline was not supplied. It does not create an unsigned certificate.
These notes do not put units on a shelf, do not issue a factory price, and do not certify a manufacturer. Where a sentence and your specification disagree, keep your specification until the supplier you select restates the equipment in a quotation. The contact form is where a gap becomes a brief. Finishing the index does not send that brief.
Park destination, pack, and freight beside the ratings, not inside them. Those lines are why two unit figures can both be honest and still not match. You may add an optional budget later, with currency and a per-unit or whole-order basis. The notes will not compute a saving, because no paired quotations are stored here. Draft from the note, then send one record.
