Zamp solar port 40A inline fuse 2022 Travato 59G

[Borgs]

Has anybody replaced their 40A inline fuse on their Zamp solar 3-port roof cap ?


My 2022 Winnebago Travato 59G's rooftop solar panels are not charging my house batteries. The single side-port for aux solar panel works when I used that, but the roof top's 3-ports do not.... so the fuse in that line must have pop. Zamp Solar said there should be an inline 40A fuse, but I do not find these among the (campervan) house fuses. Winnebago customer support does not know either where the 'engineers placed' the 40A inline fuse.


I checked both rooftop solar panels and they are giving 24V & 18V respectively going into the Zamp 3-port, but when measured at the (solar) input of the Zamp solar controller panel, there is no voltage.



Anybody know where to look?

I’ve been told there is a fuse inside the 3-Port combiner box on the roof. But, I don’t know that from personal experience. I can’t imagine how that fuse would blow. The Travato isn’t large enough for enough solar panels to be installed to surpass 40-amps.
