Features to know about
Add More Solar Charging Without Replacing Your System
If you're spending more time camping without hookups, adding another solar panel can give your batteries more charging power during daylight hours. This 200-watt monocrystalline panel expands an existing Go Power Overlander, Solar Elite, or Weekender ISW system. You can add charging capacity while continuing to use the Go Power equipment you already have.
Connect to Your Existing Rooftop Panels
The included solar branch connectors let you wire the additional panel in parallel with an existing Go Power panel. Mounting hardware is included for attaching it to your RV roof. Before adding more solar capacity, check that your existing charge controller can handle the combined output of all the panels in your system.

Unit arrived on time with no damage as it was well packed. Super easy (plug and play) to add to my existing 200w GoPower Solar that was factory installed on my Jayco travel trailer. In fact, the panels are identical. I wanted to fill out my 600w capability, but wanted to check the panel out so I only ordered 1 panel. Just placed an order for another unit.

- Recommended Solar Panel Expansion Kit that Works w/ Go Power GP-PV-200M Solar PanelsHey Greg, welcome back! The Go Power Overlander Expansion Kit - 200 Watt Solar Panel item # GP76AR includes the Overlander panel. It's a bit different than your current Go Power GP-PV-200M panel, however it is compatible. The solar panel included with the Go Power Overlander Expansion Kit item # GP76AR is a 200 watts with a slightly lower 9.6 amps. Yours has 9.62 amps. It measures 59-1/8" long x 26-5/16" wide x 1-1/2" deep which is identical in size. The included connectors will plug...
view full answer... - Sealant For Installation Of Go Power Overlander Expansion KitHey Chris! Yes, Dicor Self-Leveling Lap Sealant # DC94SR is a great choice for installation of the Overlander Expansion Kit # GP76AR. You will also want to pick up some butyl tape # DC38SR. The butyl tape will go under the mounting brackets, and you'll apply the Dicor over the screws and around each mounting point. This will create a flexible, weatherproof seal that helps keep water out. I actually installed this same kit on my own trailer, which you can see below. However, if your trailer...
view full answer... - Attaching Go Power Overlander Expansion Kit to Roof of Apex 253RLS CamperHey Dale, it looks like you ordered the Go Power 200 Watt Solar Panel Kit part # GP76AR which does come with 4 z-brackets. I do like what mentioned using the aluminum square tube as well as riveting the other side to the roof. This would for sure hold it to the roof. You wouldn't need more than the included 4 z brackets. What battery do you have in your RV?
view full answer... - Go Power 200 Watt Solar Panel with 30 Amp MPPT ControllerWelcome back Scott, The 200 watt panel you need is actually the one you are looking at, the Go Power Overlander Expansion Kit, part # GP76AR. It gives you the 200 watt solar panel without including another controller, so you can pair it with the Go Power PowerTrak 30 amp MPPT Solar Charge Controller, part # GP32QR. I like going with the MPPT PowerTrak 30 amp controller here because it is able to optimize the power coming from your solar panels instead of using a traditional PWM controller....
view full answer... - Solar Panel Expansion Kit for a Brinkley Trailer Solar SetupHey Kevin. Thanks for the information and congrats on the new trailer. Two of the Go Power Overlander Expansion Kit item # GP76AR is exactly what you need to expand your solar setup to 600 watts. These panels pull 9.6 amps each so your 30 amp MPPT solar charge controller is going to be plenty capable of handling the extra load. It looks like Brinkley uses Rich or Furrion solar panels. Both of these use the standard MC4 connectors, which is the same type of connector the item # GP76AR...

This kit works with the Overlander, Solar Elite, and Weekender ISW systems.

view full answer... - Expanding Solar on 2024 Jayco Greyhawk 31FHey Reed! Your 2024 Jayco Greyhawk 31F came standard with a 200W solar panel and dual solar controller, but Jayco doesn't specify the exact controller model in their published information. If you can send me the model number from your solar controller I can verify exactly what you have and how much solar it can handle. If you have the 30A Go Power controller that is commonly used with these systems, it can handle up to 600 watts of solar. That would allow you to add two more Go Power Overlander...
view full answer... - Butyl Tape and Sealant for Installing an Additional Solar Panel on a Grand Design RVHi Rob! Yes, you’ll want to pick up butyl tape, part # DC38SR, and self leveling sealant, part # DC94SR, to complete the installation of your additional solar panel part # GP76AR. The butyl tape helps seal underneath the mounting feet, while the self leveling sealant seals around the mounting points to help keep water from getting into your RV’s roof. For adding a second 200W panel to your Grand Design, your existing 30A solar controller should be able to handle the additional panel,...
view full answer... - Adding Additional Solar Panel To 2025 Grand Design Imagine Hey Matt! Yes, you can add another panel to your setup using the Go Power Overlander Expansion Kit # GP76AR.

The kit includes the branch connectors to wire the additional panel in parallel with your existing panel along with the mounting hardware. You'll want to pick up some butyl tape # DC38SR and self-leveling sealant # DC94SR to complete your installation. How long are you typically camping off-grid?
