My camper has a 190w Go Power panel on the roof with its appropriate contoller. Additionally, there is a Zamp port on the trailer, wired through the controller so I can add a portable panel if necessary, which I now want to do . . . My roof top panel specs:
Pm 190w
Vmp 20.4V
Imp 9.3A
Voc 24.09 V
Isc 9.98A
I've read that if you add a different panel to the system, if the Vmp of the panels differs too much, then the entire system is dragged down in efficiency. I have a little information, but . . . no actual knowledge about this . . . so, are there issues if I add a panel with a Vmp of around 18V to the system . . .
Also, the Zamp port is wired with "reverse polarity". I assume there is an adapter that will allow it to be used with non Zamp branded products. True?
There are numerous 100 to 200W folding suitcase panels available and they vary widely in price. Most have Vmp numbers around 18V.
Recommendations?
TIA
