If you are an energy-conscious RV owner, the Go Power Solar Flex 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 5 flexible 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

solar flex panel

The charging process starts with the flexible solar panels, which install 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 panels produce 500 watts per hour.

solar flex panel bent

The silicon cells are set between a laminated backsheet to withstand the elements. The panels are low profile and bend 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

mppt 60 amp solar controller

The solar controller prevents harmful overcharging by adjusting the power generated by the solar panels before it reaches your batteries. It uses maximum power point tracking technology to compare solar output to battery voltage and converts that output to an optimal amperage. Typically, this type of technology is a good fit for larger systems with higher voltages. This kit also includes a fixed-mount remote and Bluetooth dongle that install inside your RV.

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 lithium, sealed, gel, and flooded/wet cell 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.

mppt solar controller remote

The fixed-mount remote with 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 allows you to input your battery type and choose a charging profile. The remote also lets you use 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.


Additionally, a Bluetooth dongle lets you monitor the controller's settings and data from your smartphone or tablet using the Go Power Connect app. It is compatible with iOS and Android devices.

The solar controller can only accommodate either the fixed-mount remote or the Bluetooth dongle. It is unable to use both simultaneously.

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 500 how it installs

The system includes (5) 100-watt solar panels, a 60-amp MPPT solar controller, a circuit breaker, a solar disconnect, MC4 cables, and all the necessary installation hardware.

  1. Solar Panel: The solar panels install anywhere on your RV roof with included mounting hardware. To maximize sunlight collection, it is important to install the panels where they avoid shadows cast by objects, like an air conditioner or vent. The panels use MC4 cables and branch connectors to connect to the solar controller. These cables can enter the RV using the Go Power cable entry plate. This provides a covered housing and uses a quick connect setup for the MC4 cables.
  2. Solar Controller: The solar controller vertically mounts to a wall near the battery compartment. It is wired to the solar panel using MC4 cables. Then, the battery bank is wired to the terminals on the controller.
  3. Solar Controller Remote: The remote flush-mounts to a wall inside your RV. It simply plugs into the solar controller with the included cable.
  4. Solar Disconnect: The solar disconnect installs between the solar panels and solar controller. This device lets you shut off power to the solar controller for maintenance.
  5. Circuit Breaker: The circuit breaker is installed between the solar controller and battery bank to protect your equipment.

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

  • Can an AC Unit be Powered Solely from Solar Panels
    You can use a solar panel unit to help power your AC unit but since AC units pull so much power you would have to have a very large solar panel unit and clear skies to power it. To properly provide power to your AC you would need an AC/Dc panel like part # PD4045KA, a battery bank (preferably deep cycle), a large solar panel kit like part # 34275012, and either access to shore power or using a set of generators like part # 333-0003-2-0007.

    The 500-watt Go Power Solar Flex Kit with Digital Controller # 34275012 can be expanded to increase its capacity to 1000 watts. I confirmed this with my contacts at Go Power. You would simply purchase two of the 500-watt kits # 34275012 and link their separate 40-amp controllers, each of which handles the output of 5 panels. You would end up with a spare remote display but that is the only item that would be a duplicated. You would not need any other parts. This would give you a total...

  • Solar Power System for Going Off-Grid
    There isn't a particularly simple answer for a solar powered system to go off-grid, because it is totally dependant on how much power you will use per day. I have added a link to a help article entitled "How Much Solar Power Do I Need" that I recommend checking out. It depends on how many amp-hours you use per day and how big your battery bank is.

  • Is 100W Solar Panel Kit a Good Match for Dry Camping 5-7 Days in the Desert
    Location does help so don't discount that entirely, but it has more to do with how much sun you'd be getting than it does with how hot and dry the location is. With that being said, the Goal Zero Boulder 100 Briefcase Solar Panel # 287-32408 produces around 35 amp-hours a day in the best conditions (no clouds or shade gets in the way and the panels are facing direct sunlight) which should be enough if you only plan on using some smaller appliances.

  • Recommended Solar Panels for Class A Motorhome with Two 6 Volt Batteries
    In order to achieve 350+ watts of solar energy you would need a larger battery bank as you would overload the solar controller with only two batteries. The Go Power Solar Flex Charging System part # 34275012 for example provides 500 watts of solar energy but requires a six battery bank. The Go Power Overlander Solar Charging System part # 34282181 which provides 190 watts of solar energy is the most you can run with a two battery bank.
