I haven't seen these short leads on a module yet. I would not buy these modules due to MLPE needs. They might be viable with Tesla's MCI RSD solution, but I can't see making up custom cables for each panel of even each row of a ground rack. These must be for a specific segment of the market.
Thanks for posting so I can be aware before I buy any new modules. Looks like those are Jinko, which is distributed pretty widely here in Florida. I wonder if they have these short leads.
