If you are an energy-conscious RV owner, the Go Power Solar Flex charging system provides clean, renewable power and an extra boost to your batteries while you are on the road. This kit comes with everything you need to charge your RV batteries with sunlight. Using a flexible solar panel, 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

The charging process starts with the flexible solar panel, which installs on the roof of your RV. When solar energy interacts with the silicon cells in each 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 these panels more efficient than one with polycrystalline cells. And in optimal sunlight conditions, the panel produces 35 watts per hour.


The silicon cells are set between a laminated backsheet to withstand the elements. The panel is low profile and bends up to 30 degrees to suit the shape of your RV's roof, making them more aerodynamic than traditional solar panels.


Charging and Protecting RV Battery Bank

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.


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.


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

The system includes a 35-watt solar panel, a 10-amp PWM solar controller, MC4 cables, and all the necessary installation hardware.


  1. Solar Panel: The solar panel installs anywhere on your RV roof with included mounting 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 terminals on the controller. You can also install a fuse or circuit breaker (sold separately) up to 10 amps 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.

Video Transcript for Review of Go Power RV Solar Panels - 35 Watt Flexable Solar Charge Kit - GP64ZR

Hi there I'm Michael with each trailer.com. Today we're going to take a quick look at this Go Power Solar Flex Charging System. This is going to provide an off-grid charging solution for your 12 volt battery systems. Now, depending on how big your battery bank is, how much power you typically use when you're off the grid, this might just work as like a trickle charger for you. It might not fully charge your batteries, but it will put a little bit of extra electricity in there so that you can stay off the grid longer. This does have this 35 watt flexible monocrystalline solar panel.

That's going to use the sunlight to charge up your RV's batteries. Now that monocrystalline material is part of the the higher end. So it's going to be a really great option for you. If I we're to use an analogy, I would say the monocrystalline is one solid piece. So it's more like your solid wood versus some of the less expensive, cheaper style polycrystalline, which is more like a particle board kind of mentality of piecing together other parts.

So this is a really nice quality. It's going to do a good job of absorbing that sunlight and converting it to energy for you. This does have an IP rating of six seven. So it's going to do a good job of holding up in your different weather conditions. It's going to withstand water, vapor, and dirt.

This will provide 17.5 volts of electricity. So it's not going to be enough for your 24 volt system, but it will do a great job of charging up your 12 volt battery systems. As far as our dimensions go, this is right about 24 3/8ths of an inch long by 14 and 15/16ths of an inch wide and roughly 1/16th of an inch thick. So very flexible. You can bend up to 30 degrees.

So depending on where you're needing to get this mounted should be very easy either with the included screws and hardware or a with some sealant or something like that, to get it mounted on your roof. Something along those lines, it's only about just slightly over a pound. So definitely very portable. If you wanted to use it as a portable option for you. Then we're also going to get this 10 amp PWM solar controller. This is going to act as a mediary or sorry intermediary between your solar panels in your battery. So it's going to make sure that that solar power electricity flowing from your solar panels, going to your battery is not going to harm your batteries. It's going to make sure that your your batteries are well taken care of. So it's going to not only convert the solar power to a safe consistent power source for your batteries, but it's also going to monitor your batteries to make sure that it's charging them appropriately. So it's got it's got a automatic multi-stage charging system. So it's going to go from bulk mode. If your battery is really low, it'll kind of just rush all full load to the batteries that fill them up quicker. When it's gets to about 80% of its charged capacity, it will then switch to the absorption mode, which is a little bit more controlled voltage, so that you're not going to overshoot your goal and overcharge the batteries. Once they're fully charged, it will go into the float mode, which will help to maintain. So as a little bit of power is lost, it will put that in and just kind of make sure that it stays fully charged. There's also has the equalization mode. So if you have a flooded wet cell battery, that's going to prevent stratification in your battery. When the battery is being unused for a longer period of time with that float mode it's going to help to eliminate that stratification. So it's going to do a really good job making sure that everything works the way it's supposed to. Very easy to get set up. You can see we've got the little prongs here are the openings here so that we can just easily put in our power cord going in from our solar panels and then have cords coming out going to our battery. Tighten those down with a flat head screwdriver and lock them in place. And so this is going to do a really good job for you. It will also display your amperage, voltage, and battery capacity there on the screen. As far as getting this mounted, it's pretty lightweight and compact. It's about 5 and 7/8ths of an inch wide by 3 and 7/8ths of an inch tall and only roughly one and a quarter of an inch deep. So a really nice option there. They're also going to include two of these 25 foot M4 cables that will plug right in to your solar panel, depending on how much cable you need. You can potentially cut this and use the extra to go from your charged controller down to your battery. They do also include a 10 amp fuse kit. So that gives you an extra little option there, as well as mounting hardware, zip ties, hardware for getting your solar controller mounted. So pretty much everything you're going to need except for the batteries. Like I said, this is going to just be a 35 watt solar panel. So it's possible that you can add on solar panels if you need more power coming in. That's very likely depending on your your power needs and that sort of thing. We do have help articles here at etrailer.com to help you know, depending on your energy usage, how big your battery bank is that sort of thing, how many solar panels will need or can use. But this is going to be a really nice kit to help get you started. If you're looking for very flexible, lightweight option this is going to be a great option for you, but we do have other kits available as well, as well as individual components. So depending on your needs, we should have you covered. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..

system installed and worked fine. Put it on top of an old airstream, with corrugated plastic for thermal insulation, panel failed after 9 months, go power handled warranty on replacement, easy process. I have a new air gap system, but i've read that many brands of flexible panels can just fail. some people have had flexible panels working for a while.
