Connecting 2 panels/portable solar kits to get more powerUpdated 6 months ago
We do not recommend connecting two AIR GEAR Portable Solar Kits to each other (using a Y-cable), but you can separately connect two kits to one Airstream.
This solution works for Airstream trailers made from 2017 onward, with factory-installed Solar Port on the A-frame near the spare tire handle (except 2023 and later Trade Wind models).
Connect one AIR GEAR Portable Solar Kit through the Solar Port, and another AIR GEAR Portable Solar Kit through the 7-way cable (the cable that connects to the tow vehicle when you're towing). Each of these connection points is connected to the battery, and each can handle a 200 watt solar panel.
On Airstreams 2024 and later, you may need to remove the fuse for the Solar Port (found in the battery box) to upgrade it from 10 amps to 20 amps. Replacing the fuse is very simple. Please download these instructions, which include images to show you where the fuse holder is in the Airstream's battery box.
Note that the amount of net charge you get from the two panels will vary according to sunshine, the current state of charge in the batteries, and other factors.
