I've also discovered an interesting problem with my folding 160 watt panel when combined with the 95 watt roof top panel.

When the roof panel is in the shade & I set up the folding panel in the sun (one of the reasons I purchased it), the folding panel controller never goes into the boost mode, instead it only charges at the float levels.

It is annoying to see a panel that is capable of putting out 8.5 amps only producing an amp or two in full sun. While I don't have an easy way to prove it since it is difficult to disconnect the built in panel, I suspect the problem is the two controllers fighting each other, with the roof top panel putting out enough voltage to convince the portable controller that the batteries are full.

My solution, when I get back to NY, will be to bypass the folding panel's controller & combine the panels feeding either the GoPower's controller or purchase a different controller that is better matched to the Interstate battery charging requirements.

Is that when you hook your folding panel directly to the battery or when you 7 pin into the pig tail?

It is through the 7 pin connector - I use that because I have a battery monitor that I use to determine the output. When I have a heavy load on the system & both panels in the sun, the portable panel does put out 8.5 amps.

When the time comes that you by-pass the folding panel's controller and choose to use the GoPanels controller will you be using MC4 connectors or the 7 pin?

That's bizarre, but maybe not a problem for paralleling - Escapes with the 95 watt panel obviously don't have the panel frame connected to the trailer frame, and apparently the panel frame is live compared to the trailer ground... good thing it's only 12 volts! The key is apparently to not connect either panel frame to the trailer frame.

The choice of connectors is still out, but it won't be the 7 pin since I'll want to feed the input of the controller.

I'd like a waterproof chassis mount connector since it won't be in use when I'm just using the built in panel. I've used & like the Neutrik SpeakerON connector and it is sealed, but no cover. The problem with most chassis mount connectors are they are outlets, not inlets, which I would prefer with a solar panel. I'm still looking...

If you are referring to cable connection, the item you could use is a flanged inlet. It looks like the male end of a drop cord, but it is recessed into a housing. I use them on my solar controller to connect the array to it. A standard drop cord between the array and controller is simple. The wiring at the controller either parallels or series the panels as necessary. I use a morning star mppt controller which takes up to 75V open circuit.

Jon, Have you been able to test bypassing the folding panel's controller?

PS: I really enjoy reading your trip reports.

Jon, If you have yet to find a connector, how about one of these? They have them on Amazon as well but the image is not as good.

Marinco 150BBIW.RV White 15 Amp Power Inlet

Must be what Strawberry mentions.

So, what is the solution to adding a second panel and having them work together vs against one another?
