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

solar flex 30

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 30 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

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.

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

flex 30 how it installs

The system includes a 30-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. 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 Go Power RV Solar Panels - Roof Mounted Solar Kit - 34272631 Review

Speaker 1: Today we're going to take a look at the Go Power 30 watt solar flex kit with the 10 amp digital controller. This kit will include everything laid out here on the table. One solar panel, the 10 amp PWM solar controller, in-line fuse holder with the 10 amp fuse, 25 feet of cable, all the mounting hardware you need, and a nice set of detailed instructions.Now this is a flex solar panel can conform to almost any surface, perfect for RVs and boats. The panel will allow bending up to 30 degrees. It is a nice lightweight low profile design. And the solar panel is made of a laminate TPT back sheet with stainless steel grommets, and it uses the noncrystalline cells.

It's very easy to install. It can be affixed by either adhesive or screws.Now the other main thing in this is the 10 amp digital solar controller. It maintains the life of your battery by preventing overcharging. This controller will regulate the current flow from your solar panels to your batteries. It uses temperature compensated pulse with modulation charging, does three battery charging profiles, sealed and gel, agm and flooded.

It uses four stage charging bulk absorption float and equalize. Has a nice backlight LCD screen, which will display the charging current, battery voltage, and battery state of charges. Uses maximum power boost technology to let you manually bulk charge at any stage of the charge cycle. Also has battery reverse polarity protection, solar array reverse polarity protection, also over temperature protection, and over current protection. It's very easy to install.

It's flush mountable. Overall wattage is 30 watts. Overall power current is 1.7 amps. Maximum power voltage 17.6 and a maximum power current of 1.7 amps.A few dimensions on these, we're gonna start with the solar panel. The solar panel is gonna be about 24 and 1/2 inches long.

15 inches wide. And since it's flexible it's only about 1/8 of an inch deep. And the weight of it is about one pound. And on the controller itself, the digital solar controller. Dimensions on that, let's put a ruler on it. Length on it is gonna be right at about 5 inches long. Height on it is gonna right at about 3 and 7/8 inches tall. And the total depth on it is right at about 1 1/4 inches deep. But that should do it for the review on the Go Power 30 watts Solar Flex Kit with the 10 Amp Digital Controller.

Ask the Experts about this Go Power RV Solar Panels

  • Recommended Converter and Charger for Single Lithium Battery on 5th Wheel Trailer
    Yes. Because lithium batteries have a full charge voltage of 14.4 to 14.6 volts, your standard battery charger/converter system will not be able to fully charge a lithium battery so you will need to upgrade your system. The Progressive Dynamics # PD9160ALV is compatible with lithium batteries and will work well for your single 100ah lithium battery. The # PD9160ALV is a 60amp converter and since it turns off automatically to avoid over-charging, it will help prolong the life of your new...

  • 12V Power Requirement for Furrion 2-in-1 Range Oven
    The Furrion 2-in-1 Range Oven # FSRE21SABL needs 12V power for its cavity light (the one inside the oven) and for the back-lit controls. The total power requirement for all of the lights is less than 2-amps total, according to my contact at Furrion. She also confirmed the actual gas burner ignition system does NOT require electrical power because it uses a pulse ignition like a patio gas grille. 12V operation at 2-amps would require a 24-watt input. A good option is the 30-watt Go Power...

  • Will 10 Watt Solar Panel Kit Fully Charge a 35 Watt Battery
    It all depends on how many amp hours your battery is rated for and how much sunlight you have available. The Go Power Eco Solar Charging System 10 Watt Solar Panel # 34273836 has an amperage rating of 0.57 amps which means it is just a trickle charge application and is really only meant to keep your battery topped off when your camper is in storage. This should be the case for your 10 Watt panel as well. To make sure you get a solar panel kit that will allow you to only charge it via...
