Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Dry camp in a 15' - 25' motorhome, van, or Airstream and want this "Goldilocks" option to get just the right amount of power for your setup
  • Split your time between campgrounds and boondocking and need a system that equips you for either
  • Like getting a kit with all the parts needed but already have an inverter

No, if you:

  • Usually park your camper or RV in the shade, in which case portable panels would suit you better
  • Are intimidated or unable to get onto your rig's roof to install and adjust the panels
  • Worry about drilling into your roof

If you are an energy-conscious RV owner, the Go Power Overlander solar charging system provides clean, renewable power and independence from the grid. This kit comes with everything you need to charge your RV batteries with sunlight. Using 3 solar panels, this system collects solar energy to create DC power that passes through a solar controller to charge your RV batteries.


How It Works


Collecting Solar Power

go power solar panel

The charging process starts with the solar panels, which install on the roof of your RV. When solar energy interacts with the silicon cells in the panel, it generates a flow of DC electrical current that charges your RV's batteries. Each of the monocrystalline cells is made from a single crystal of silicon, so the electrons that create the current have more space to move, making this panel more efficient than one with polycrystalline cells. And in optimal sunlight conditions, the panel produces 570 watts per hour.


solar cells

The silicon cells are set between a cushioned backing material and tempered solar glass to withstand the elements. The glass has low-iron content to provide exceptional transparency, which ensures maximum sunlight collection. Finally, the panel is framed with anodized marine-grade aluminum to resist rust and corrosion.


go power adjustable arms

An adjustable mount kit (sold separately) can increase your solar panel performance by angling it for maximum sun exposure. This kit replaces the panel's existing brackets and allows it to tilt at 3 different angles. This also improves solar charging during winter months when the sun is lower in the sky.


Charging and Protecting RV Battery Bank

go power solar controller

The solar controller prevents harmful overcharging by adjusting the power generated by the solar panel before it reaches your batteries. It uses pulse width modulation technology to regulate the output through pulses that provide a consistent charge. Typically, this type of technology is a good fit for smaller systems with lower voltages.


Using a multistage charging system, the controller automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel, AGM, flooded/wet cell, and lithium batteries.


Charging Modes

  1. Bulk: This mode charges at the full rated load for a quicker recharge time. As the name suggests, this is where the bulk of the charging happens. It typically charges the battery to at least 80% capacity.
  2. Absorption: This mode provides controlled voltage to ensure a full charge. Once the battery reaches between 80% to 90% capacity, the absorption state will kick in and start charging at a regulated voltage. In each charging profile, this mode is set to last for 30 minutes after the bulk charge is completed.
  3. Float: Once the battery reaches full charge, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
  4. Equalization: On flooded/wet cell batteries, this mode activates to prevent stratification and sulfate buildup during extended float cycles. These two issues can damage a battery by causing the accumulation of acid at the bottom of the battery and hardened sulfate crystals on the battery plates. This mode is especially helpful when your battery is going unused during storage.

With Maximum Power Boost Technology, you can simply press a button to activate Bulk mode for the highest charging voltage. This lets you quickly top off your battery bank before the end of the day by capturing as much power as possible.


solar controller terminals

This solar controller is built to charge two battery banks and has terminals for a primary and secondary battery. Your primary battery will receive the full current until it is completely charged. Then, your secondary battery will start to draw the charge current.


solar controller digital display

The backlit, digital display acts as an information center for your solar panel output. It shows the charging current, battery voltage, and battery state of charge. It also allows you to input your battery type and choose a charging profile. Additionally, a built-in USB port on the front of the controller provides a convenient outlet to charge your cell phone or tablet.


It includes a Bluetooth function that lets you connect the controller to your smartphone or tablet with the free Go Power! Connect app. With this app, you can wirelessly view the same live battery information included on the display. Also, you can control your battery profile and toggle Maximum Power Boost Technology mode.


Lastly, the controller includes several built-in safety features to help protect your equipment. The charging process will shut down if the controller starts to overheat and when an overcurrent is detected. Also, if the battery or solar panel is wired incorrectly, it activates a reverse polarity alarm.


How It Installs

overlander how it installs

The system includes 3 190-watt solar panels, a 30-amp PWM solar controller, MC4 cables, and all the necessary installation hardware.


  1. Solar Panels: The solar panels install anywhere on your RV roof with included mounting feet and hardware. To maximize sunlight collection, it is important to install the panel where it avoids shadows cast by objects, like an air conditioner or vent. The panel uses MC4 cables to connect to the solar controller. These cables can enter the RV through the refrigerator vent or using a Go Power cable entry plate (sold separately). The cable entry plate provides a covered housing and uses a quick connect setup for the MC4 cables.
  2. Solar Controller: The solar controller flush-mounts to a wall inside your RV. The manual includes a mounting template with measurements to ensure proper installation. It is wired to the solar panel using MC4 cables. Then, the battery bank is wired to the primary terminals on the controller. If you are using additional batteries, they can be connected to the secondary terminals. The included 30-amp fuse is installed between the solar controller and battery for additional current protection.

Note: This kit may require more wiring and additional parts depending on your RV setup.

Review from a similar Overlander Solar Charging System in RV Solar Panels


I have had the overlander solar package installed now for 6 months. My Jayco Greyhawk had the go power wires pre installed so the installation was very easy. My only regret was not buying two 190 watt panels. As for 4 star rating, did not have it long enough to justify 5 stars.

I have 2 deep cell lead acid batteries, the instructions are not very clear which to choose, sealed or flooded. Presently selected on flooded type and I think that maybe the controller is overcharging them, due to corrosion on the positive terminal.

Review from a similar Overlander Solar Charging System in RV Solar Panels


The solar kit was exactly as represented in the description. The ability to watch a video of an installation was very helpful even though the installation was not that complicated in our case since our trailer was prewired for it. Be sure to order butyl tape and sealant to make sure the installation is waterproof. Answering questions and prompt delivery is a definite plus for working with etrailer.

Review from a similar Overlander Solar Charging System in RV Solar Panels


I love my Go Power Solar system. Before getting it my coach battery would drain down even though I had everything turned off. Now when I go to the storage yard ,even after a extended period of time, my coach and chassis batteries are at 100%. I recommend the Go Power Overlander Solar Charging System RV Solar Panel.

Review from a similar Overlander Solar Charging System in RV Solar Panels


Prefer to give zero stars. My review is not in regards to the product but for etrailer.com & their lack of customer support.

Received damaged product as shown in images. Shipped in factory package with zero additional effort to maintain product integrity. Glass panel inside a cardboard box inside a cardboard box... what could go wrong?

Called to report damage & asked to submit photos. Done & no response. Two days later & 60+ minutes of hold time and get no support other than preprogrammed customer service BS. No one can actually provide info as to when replacement will be sent, why it cannot be expedited as a damaged replacement & inconsistent feedback on what to do with damaged product - I guess I'm on the hook to pay for disposal?

I used to be an ardent supporter of etrailer.com & referred them often. Used to be phenomenal support but now is nothing more than a typical corporate entity... "please hold for the next available service agent who has no idea how to interact with a customer other than reading from the corporate manuscript"

Review from a similar Overlander Solar Charging System in RV Solar Panels


I love this kit and it is used to keep the coach battery charged and topped off. The panels are installed on the roof (second panel purchased). I also like the Bluetooth monitoring system that hooks to my cell phone. When I'm dry docking, it charges the battery back up after a night of running the Furnas (gas).

Review from a similar Overlander Solar Charging System in RV Solar Panels


Super setup. The instructions were very clear and it was relatively easy to install especially if your unit is pre-wired for the Go Power solar. The price was $[XXX] cheaper than the dealer quote for the setup and I save a couple hundred dollars in labor. etrailer gets my vote for excellent service and price.

Review from a similar Overlander Solar Charging System in RV Solar Panels


Solar Panel works. Everything went well. etrailer is great. So why not 5 stars. The app that comes with the controller is junk. No other too say it. You need the app for some setting resets. I have spent more time on this, than 10 installations. The app actually caused me go with another brand solar panel for my portable one. I wish etrailer carried other brand options. I wrote this after 4 weeks of trying to this figured out, just to make sure I have tried everything I know.

Review from a similar Overlander Solar Charging System in RV Solar Panels


I love "go power" the second unit that I have installed. It not only charges my house batteries but it also charges my coach battery. The system install is easy and straightforward enough. high quality workmanship and well-thought-out kit. Running the wires was the hard part!




by:

Review from a similar Overlander Solar Charging System in RV Solar Panels


We installed these solar panels on our 2017 Forest River Sunseeker in June 2019. We love them! We dry camp regularly and never worry about low batteries or running the generator. It is well worth the investment!




by:

Review from a similar Overlander Solar Charging System in RV Solar Panels


The solar panel was just as expected. The install was easy, (as soon as I figured out how to run the wires from the roof to the battery compartment). Take your time, and you don't need to install the control panel in your rig. I installed it in the battery compartment, then I installed the APP on my phone.

  • Can a 2nd solar panel be added to Go Power Portable Solar Panel to charge 3-100ah Lithium batteries?
    You technically could add a second Go Power Portable Solar Panel with Digital Solar Controller - 200 Watt Solar Panel # 34282610 to power your travel trailer's lithium batteries, however, this would require some custom wiring to the controller as Go Power doesn't sell a kit to make this process quick and easy. The better option would be to upgrade to a system that is more capable of charging your 3-100ah lithium battery bank, and for that I recommend the Go Power Overlander Solar Charging...
