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 panel

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 100 watts per hour.

solar flex panel bent

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

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.

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 100 how it installs

The system includes a 100-watt solar panel, a 30-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 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.

Video Transcript for Go Power RV Solar Panels - Roof Mounted Solar Kit - 34272630 Review

Speaker 1: Today we're taking a look at the Go Power! 100 Watt Solar Flex Kit. The solar flex kit is perfect for RVs and boats. Its flexible design can conform to almost any surface, which gives you a lot of options when it comes to mounting the panel. The kit converts the sun's energy into DC electricity and then that electricity actually charges your batteries and ensures that you have power when you need it.The unit features 100 watts, or 5.68 amps of charge power and the kit comes with what you need to keep your batteries charged. It is able to charge up to two batteries at a time. The panel can be installed by adhesive or with mounting screws.

Mounting screws are included. It also has the stainless steel grommets that are already installed to ease installation. The solar panel is durable, allowing a bend of up to 30 degrees.It's a really nice flexible design. It comes with everything laid out here on the table as well as your owner's manuals, but basically you get the solar panel. Again, this is a 100 watt solar panel.

You get the 30 amp digital PWM flush mount solar controller. This is the brains of the unit. You get the necessary installation hardware and you get all of your wiring connectors. Also, you get a fuse and a fuse holder, so it is fuse protected and that is a 30 amp fuse.Then it comes with your MC-4 red output cable and MC4 black output cable. Now the solar controller which is this unit here, this unit regulates current flow from your solar module to your batteries.

This allows you to choose your battery type and charging profile. It has a backlit digital display, so it's always easy to see. Again, this is your brains of the unit. It features different charging profiles such as flow charge, bulk or absorption charge, and equalization charge.It also features an automatic equalize feature that will charge and recondition your batteries once-a-month at a higher voltage to ensure that any excess sulfation is removed. It also features maximum power boost technology.

This allows you to override the normal charging algorithm of the solar controller and it's designed to be used before the end of the day if you know you will require many loads through the night.It can also be used when you just have installed the solar controller to put batteries on a boost charge right away. Now the controller displays voltage, PV-charging current and batter state of charge. Errors will also be displayed so you can quickly identify and resolve any issues. It offers a standard USB connection point right here for delivering five volts to small mobile appliances such as cell phones, tablets and small music players.On the bottom, it also features a connection point for connecting an inverter. The controller also offers battery reverse polarity protection, solar or ray reverse polarity protection, over-temperature protection and over current protection. When it comes to the solar panel, when it comes to the construction, we're looking at a laminate TPT back sheet. Again, it has the stainless steel grommets and the monocrystalline cells.The panel dimensions is 44 and 5/8 inches long from the edge of that end to the edge of this end. It's 21 and 7/16 inches wide by 3 millimeters or 1/8 inches thick. The panel itself weighs about 2.9 lbs., so it's extremely lightweight. Maximum power voltage is 17.6 volts. Open-circuit voltage is 20.8 amps. Short circuit current is 6.14 amps and the maximum system voltage is 600 volts DC.Now, I want to point out that if you're going to be using sealant or any adhesive, that will depend on the roof membrane material and that's why it's not included with this kit. Basically, when you're ready to install it, you need to pick out a good location for your solar panel. You want to get a lot of sunlight. It has your positive and negative cables right here with the quick connects on it.These quick connects will connect to the quick connects on the cabling, so red is positive, black is negative. Then, these cables on the other end, it has the bare wiring. That fits into the control box right here, so you have battery one, positive and negative; battery two, positive and negative. Then right here in the middle, you have the positive and negative connection points for the solar panel which would be your red and black wires included with the kit. Speaker 2: That's going to do it for today's look at the Go Power 100 Watt Solar Flex Kit.

  • Can I Walk on the Go Power Solar Panel?
    It is not recommended to walk on the solar panels when they are installed on your roof. In the installations we typically do here we like to leave some space for folks to walk through should they need to get to different items on the roof. As far as cleaning goes you can use any mild detergent type of soap to clean them on a regular basis. I would stay well away from any harsh chemicals or anything that has any type of abrasive properties. I recommend after doing your wash stage that...
