So this (4.7mm) is a "12 volt panel cable" and the Nomad "Super Charge" is a "6 volt panel cable". Is that correct?
Why not list them that way? For a while I was getting excited that the Guide 10 et all could take in any voltage panel ("6-12")
And still wondered if the panels (esp 3.5 and 7) had a blocking diode (being paralleled to the higher voltage panels). That due to the "inefficiencies in interconnecting".
The most adjacent answer indirectly clarified that by listing the connectivity of ports (eg 12V port from Nomad 7 for the 4.7mm cable).
So that explains all the inneficiences - and why a simple piece of wire - the Super Charge Cable - works for Nomad X to Guide 10 - The Guide 10 is built for 6V nominal panel whereas everything else (Sherpa +) is built for 12V nominal panel.
Solar can certainly be confusing - and I'd bet that's why no direct mention of panel voltages and how that relates to interconnect. But people will do inefficient things without. How about a table?
