Best Solar Panels For A Zamp Ready Trailer And How To Use Third-Party Panels
If you have an RV, travel trailer like an Airstream or a fifth wheel with a Zamp solar port, you can connect solar panels through this port to your 12V RV house batteries.

How big of a solar panel you need to charge your RV batteries depend on a couple of factors, and if you’re not sure what you need I recommend reading my post on this topic, click here to view it.
These Zamp panels are made in the United States with high-quality parts and are compatible out of the box with the Zamp solar port. For this reason, they’re the best solar panels for a Zamp ready trailer.
But you’re not limited to using Zamp solar panels with a Zamp solar port, and that’s what we’ll focus on down below – How do you connect third-party panels to this Zamp solar port?
Best Solar Panels To Use With The Zamp Solar Port

Here are my solar panel recommendations for the prewired Zamp solar port, the links below will take you to the product page on Amazon.com.
Renogy 100 Watt Eclipse Monocrystalline Solar Suitcase – The Renogy Eclipse panel is my top recommendation. It’s a very portable and efficient solar panel that will charge your RV batteries quickly. It comes with a built-in charge controller that tells you state of charge and amperages, a kickstand, and includes a carrying bag for easy transport. Also available in a 200W kit. Both require the iGreely MC4 To SAE 10AWG to make the connection.
Zamp Solar 140-Watt Portable Charger Kit – The Zamp solar panels are good choices since they’re made in the US and come with a 25-year warranty. They’re high-quality panels and have a better kickstand than the others. Compatible with the Zamp solar port right out of the box. They’re also available in 45W, 90W, and 230W. These don’t require any additional adapters.
HQST 100 Watt 12 Volt – Another great option, by a company called HQST. Not as popular as Renogy because they’re less known, but it’s basically the same thing as the Renogy panel above. Requires the iGreely MC4 To SAE 10AWG to make the connection to the port on your camper.
Renogy 100W Portable Kit – I have two of these, and they’re very similar to the Eclipse panels above. Kickstand, charge controller, carrying case. Easy to set up and transport. Requires the iGreely MC4 To SAE 10AWG to make the connection.
Renogy 50W Portable Eclipse – If you only need to charge up your 12V RV batteries to use a water pump, furnace/bathroom fans, LED lights, and light 12V TV use, this 50W panel will be enough. It comes with a charge controller that has a USB port so you can charge phones, tablets, lights, and speakers directly with the solar panel. This panel comes with alligator clips, so what you can do is buy a Kuncan 25Ft Sae to Sae Cable, cut the side with the Sae connector that has a positive male Sae connector, and stick it into the charge controller on the solar panel after detaching the alligator cable wires. If you set it up the right way it can be plugged into the Zamp solar port without using any additional adapters.
What To Think About When Using The Zamp Solar Port
The main thing you must know about the Zamp solar port is the type and its polarity. Polarity means which side is positive and which is negative. The plug used by Zamp is called an SAE connector.
This image from teardrop-trailers.vanillacommunity.com shows it in an easy to understand way.
When you plug a solar panel into this port, you should be able to follow the positive wire going all the way from the solar panel, to the positive terminal on the Zamp port. Let’s call the positive terminal on the Zamp port male and the negative terminal female.
It’s very important that the polarity is correct when you plug it into the Zamp port. It’s easy to follow the wire and make sure it’s correct.
Now, let’s take a look at the adapter we can use to plug third-party solar panels into this port.
The Adapter You Need To Connect A Third-Party Solar Panel To A Zamp Ready Solar Port
What we’re looking for is an MC4 to SAE adapter, like the iGreely MC4 To SAE 10AWG.
This adapter comes with a small SAE polarity switch adapter, so you can switch the polarity. We’re going to use this little adapter to make the correct connection (unless your solar panel has a negative male connector and a positive female connector).
Most solar panels are shipped with MC4 connectors and based on my experience, it’s more common that the solar panel has a positive male MC4 connector and a negative female MC4 connector (every panel I recommend down below do).
That means that this adapter wouldn’t be compatible if you only look at the wire colors, but we can still use it even if the colors of the wire is wrong, as long as we follow the positive/negative wire and make sure it’s right when we plug it into the Zamp solar port.
So, let’s say we have one of the panels I recommend down below, with a positive male MC4 connector, and a negative female MC4 connector.
We’ll plug the positive (red) male MC4 connector from the solar panel into the female MC4 connector on the adapter (the black wire). Then we’ll plug the negative (black) female connector into the red male MC4 connector on the adapter. It feels wrong to connect the wrong colors, but this is how we’ll have to do it.
Now you’ll have the positive wire from the solar panel going through the adapter, to the male side on the SAE plug on the other side of the adapter. Now we need to reverse that polarity, so we’ll use the little SAE adapter included with the iGreely adapter. Now the positive wire from the panel ends up with an SAE female, which is what we need for the Zamp solar port.
Remember, the male SAE on the Zamp port is positive. The female SAE on the Zamp port is negative. When using the solar panels below, there will only be one way to connect the MC4 connectors, but you do have to use the reverse polarity adapter with the iGreely adapter before plugging it into the Zamp port.
What To Think About When Choosing A Solar Panel
I haven’t found any information about the size of any fuse on the Zamp solar port between the port and the wire to the batteries. But since Zamp sells 230W solar panels that generate 12.6 amps, if there is a fuse it must be at least a 15A fuse.
You need to choose a solar panel with a solar charge controller built-in or buy a charge controller separate. The Zamp solar port is a direct connection to the RV batteries, so any solar panel that isn’t a trickle-charger should be used with a charge controller that protects the batteries from overcharging.
The panels I recommend down above come with a charge controller so you don’t have to do any additional wiring on most.
How Long Will It Take To Recharge My RV Batteries?
This is a question that’s hard to answer in one sentence without knowing the size of your batteries and solar panel. I have written a post that goes into this and how you can calculate it, click here to view that post.
Are There SAE/MC4 Extension Cables?
Yes, there are. The Ovitar 16AWG 12Ft Extension Cable (click to view on Amazon) is an example.
I use MC4 extension cables, and you might want to do that as well if you choose a panel with MC4 connectors. I recommend WindyNation MC4 extension cables that come in different sizes and lengths.
Will A Solar Panel Power The Outlets In My RV Camper?
A 12V solar panel connected to your trailer batteries will recharge these batteries, but won’t provide 120V AC power to your outlets.
To use your outlets, you’ll need to use an inverter that changes the 12V DC power to 12V AC power. An example of an inverter like that is the KRIËGER 1100 Watt 12V Power Inverter that has two AC outlets.
You can wire this inverter to your batteries, then plug your camper into one of the outlets with a 15A to 30A adapter, or a 15A to 50A adapter depending on the size of the electrical system in your camper.
