Me to Dave..... Since my MPPT

details/options with Sunpower Support thru their local distributer/installer SWEP.
The factory is here in the Philippines
, so they should hopefully provide some clarity. (but small marine
applications void warranty and confuses land focused installers)
My layman’s understanding at this point… is that the “N” Series modules are not designed for positive ground and therefore become less efficient, when negative ground .(How much we need to confirm?)
Could be that they can still be wired positive as Dashew did with his E20/327’s… and work at optimum rating but that needs to be confirmed
See Dashew’s blog on how he wired positive… and some of the comment concerns…from others

Definitely appreciate input from anyone like Cotemar who has installed the Sunpower Panels as to how they wired them?
