I made this connector so that I can use the suitcase on other Vehicles if I want to.

It is a two pole SAE connector. Others use the waterproof MC4 connector. So you would need the panel(s) through an adapter into your Zamp connector, after which you would have to insert a controller prior to connecting to you battery bank. Alternatively, you would go from your panel(s) to an external controller and then to you bank.

I was going to install a controller inside the trailer however the Zamp ready plug on my trailer is pre wired to the battery system I would have to rip the wall out to get to it on the inside of the trailer.

The adapter I made to plug into the trailer was very simple. From the "Zamp" SAE connection on the trailer I made a plug with a SAE connector on one end and MC4 connectors on the other end. I also put a MC4 fuse link connector on it.

I have 2x90 watt each suitcase high efficiency Chinese panels that cost less than $130 each delivered. A slightly upgraded 30 amp controller was less than $30. You will spend some money on the connectors and cables. Then it's an SAE to the port on the RV wall. You have to protect the controller and could Velcro it to one of the panels if need be.

You can also get 10-20 amp simple controllers on eBay for very little money.

The Renogy 100 Watt suitcase was around $250 compared to the Zamp 120 Watt suitcase that cost $600+ and Renogy has upgraded the controller they use from a 10 AMP to a 30 AMP (better controller).

This isn't the way I had planed to set it up but in the long run I think it will be better as I can still use the suitcase with any other vehicle or system I want to other than the trailer..
I should correct one thing in my last post the Extension cable I used is 10 gauge not 8 gauge.

I just purchased a 2016 bullet. I was told it was solar ready and that was it. They didn't even tell me it was zamp solar ready. I found that bit of info online.

As has been previously mentioned, it will work with any solar panel that feeds a controller. All that's needed is the SAE adapter to connect the battery output terminals of the controller from the panels to your trailer.

Can't wait to receive my Forest River Mini-lite 1905 so I can trace the circuitry and advise the solution implemented.

It will probably be from my panels' MC4 output to an adapter to the SAE connector on trailer. Then install a controller inside the trailer from the SAE input. Then, from the controller to the batteries by the existing cable from the SAE connector to the batteries. That way I can still use my panels with the solar generator I've built for my house. Stay tuned.
