What Components Do I Need for Off-Grid Solar?

Solar power systems are quickly gaining traction across the US. Once a renewable system mainly reserved for hot and dry climates, homeowners in rainy and cooler states just weren’t interested. Fast forward about five years and on-grid solar power systems are becoming more and more popular in the northern states. This trend is thought to have started because of lower prices and better technology. Solar panels that perform better in low light environments, such as the Renogy Eclipse, are great contenders for a northern power system because they can perform fairly well even on a cloudy day. With power costs rising, consumers are turning to solar to meet their needs while staying within their budgets. Even though some northern homeowners still aren’t interested in on-grid solar, that doesn’t mean there isn’t a different kind of system to suit their needs.

Off-grid power systems can be used by anyone, anywhere in the US. Since these systems are not excessively large and do not get installed on the roof, they are often a DIY project. Furthermore, they are a perfect go-to item in the event of a power outage, which of course, can happen anywhere in the US. Off-grid systems are also less costly than an on-grid system, particularly because they don’t require professional installation. For all of those reasons, off-grid systems are become must have items on RVs, boats, and campers. Many customers are also choosing to store these kits in their basements or sheds in case of an emergency.

If you’re in the market to purchase one of these kits, one of the first questions you’ll ask is, “What do I need?” To make things simple, Renogy sells several Complete Kits that come with all of the components necessary for an off-grid system. Every off grid system requires solar panels, but that is a given. Each solar panel contains a junction box with MC4 leads. These leads connection to another MC4 adapter kit, which is in turn connected to a charge controller. The size of your system will dictate which Amp size controller you’ll need to purchase. Aside from amperage, you may choose to purchase either an MPPT or PWM charge controller. MPPT charge controllers are more expensive than PWM controllers because they feature better power tracking technology. MPPT charge controllers help extend the life of the battery bank and help create a more efficient power system.

In addition to a charge controller, all off grid systems require a tray cable, which extends from the charge controller to the battery bank. You’ll also need to purchase mounting Z-Brackets if you intend to have the system installed on a surface suck as a boat deck or RV roof. Last but not least, you’ll need to purchase an inverter if you intend to use your off-grid system with regular consumer appliance. That is because the power generated from your system will need to be converted from direct current to alternating current. You may choose to purchase a Tracer Meter, which monitors and displays the solar system’s voltage and current, as well as amp-hour and watt-hour charge levels. However, this component is completely optional.

Here at Renogy, we’d love to make your journey into solar energy as easy as possible. That’s why we’ve created Complete Kits, which do contain all that is needed to set up an off-grid system. Of course, you’re free to mix and match or buy specific components elsewhere, which is what makes this list a must read.

Where to Purchase Renogy Products

If you’ve been researching solar panels, you’ve surely stumbled upon Renogy Solar. Renogy has been in business since 2010, when the company CEO, Dr. Li, began selling solar panels on Amazon and Ebay. We’ve come a long way since the Ebay days, but as our business grew, so did the number of secondhand sellers. While many of these sellers may be approved retailers, it is difficult to know for sure. With all the different vendor options available, you may want to learn where Renogy maintains seller accounts.

To date, Renogy still sells on Amazon and Ebay, but has expanded sales into its own online store (, showroom, and several other online retailers. On Amazon, the Renogy seller account is simply “Renogy.” We sell a variety of solar panels, kits, and accessories on Amazon, many the same items available at On Ebay, Renogy’s seller account is renogysolar. After launching the online store website, originally, we started listing and selling products on a number of lesser-known “marketplace” websites including, Newegg, and Sears. When Walmart started opening its website to third party retailers, Renogy began placing listings on that website as well. However, Walmart has since begun selling Renogy Solar Panels directly.

 Most recently, Renogy started placing product listings on If you start your internet search for Renogy products, it wouldn’t be unusual to find a number of third party, unrelated sellers advertising products. To avoid purchasing a potentially defective or counterfeit product, you should attempt to verify that the seller is an authorized retailer. If you purchase a defective or counterfeit product from an unrelated third party that is unauthorized, Renogy may refuse to replace or fix the product. If you live close enough to our Ontario, California office, you can also stop by the showroom to test the products and purchase in-person. Happy shopping!

Renogy Rover MPPT Charge Controller Product Release

To all of our solar fans out there: if you’re looking for ease of use and sky-high off grid efficiency, then look no further than the Rover MPPT Charge Controller. Like the popular Adventurer and Wanderer controllers, the Rover is the newest addition to the Renogy TravelerTM Series. The Rover comes in 20A or 40A to best suit a customer’s needs. However, unlike an ordinary PWM charge controller, the Rover features MPPT tracking technology. MPPT stands for “Maximum Power Point Tracking,” which allows for an up to 99% tracking efficiency! What really sets this great solar charge controller apart is its error code detection feature. This feature allows you to self diagnose system faults by reading the code on the LCD screen. The body of the Rover is composed of die-cast aluminum for better heat dissipation, and the included cables allow for the measuring of the battery temperature and remote monitoring. Like any other MPPT charge controller, the Rover 4-stage charging: Bulk, Boost, Float, and Equalization. They may only be used with sealed lead-acid, flooded or gel deep cycle batteries.

The 20A MPPT Rover Charge Controller is available for purchase for $139.99 at, while the 40A MPPT Controller is priced at $209.00. Optimize your system efficiency and the lifespan of your battery bank with a new Rover Charge Controller. For more information, visit:

Travel With Renogy Charge Controllers

If you’ve been following Renogy, you’ve probably seen all of the new products introduced in 2016. From new solar suitcases to generators, Renogy has been hard at work designing products to better suit customer needs. When Renogy first launched years ago, it only carried basic 10A and 30A PWM solar charge controllers. While these controllers were inexpensive, they weren’t entirely user friendly and customers often had to call in with questions. It wasn’t long before we figured out that customers would be willing to pay a little more for a better designed charge controller, so we set out to develop a state-of-the-art line of controllers that are both easier to install and use. We decided to call this new line the “Traveler Series,” keeping in line with the company’s outdoors and adventure theme.

The earlier introduced “new and improved” charge controllers included the Adventurer 30A PWM Charge Controller and the Wanderer 30A Charge Controller. Unlike the basic controllers that Renogy previously carried, the Adventurer and Wanderer are compatible with sealed, gel, and flooded batteries. The Adventurer Charge Controller features an LCD display screen that shows the current power generation, temperature, voltage, and charging current. Perhaps most importantly, the Adventurer is designed for clean flush mounting in RVs, trailers, and boats. The LCD and mounting features were not found on many of the first generation charge controllers. Renogy has received a great deal of positive feedback from customers, especially those using the charge controllers in recreational vehicles. The Adventurer 30A Charge Controller is included in all RV Solar Kits and the Wanderer 30A Charge Controller is included in all standard Starter Kits greater than 50W, all standard Premium Solar Kits, and all standard Complete Kits.

In mid 2016, Renogy introduced the Commander MPPT Charge Controller. The “MPPT” stands for Maximum Power Point Tracking technology, meaning that this controller will more efficiently charge the battery bank. This controller is also compatible with sealed, gel, and flooded batteries, making it more versatile than the original MPPT controllers offered by Renogy. In addition to MPPT technology, this controller also features Multiphase Synchronous Rectification for improved system performance. Although it is a pricier option, its tracking efficiency is as high as 99%, while the conversion efficiency is up to 98%. The Commander Charge Controller is offered as an upgrade in the Starter, Premium, and Complete Solar Kits. The Commander is offered in three options: 20A, 40A, and 60A.

Eclipsing Competition: The Renogy Eclipse Solar Suitcase

If you’ve shopped with us in the past, you’ve likely taken notice of our highly efficient 100W Monocrystalline Solar Panels. The standard Renogy Monocrystalline 100W Solar Panels feature module efficiency rates of 15.47% while the 100W Polycrystalline Solar Panels have efficiency rates of 14.56%. These efficiency rates meet or exceed those of other market competitors. Within the past year, Renogy introduced the Eclipse 100W Monocrystalline Solar Panels to its store inventory. The Eclipse line of solar panels feature module efficiency of 18.35%, allowing the panels to be smaller in size and about the same weight as a standard 100W Monocrystalline Solar Panel.  Of course, a smaller panel allows for easier storage and transport, but it still leaves one to wonder how to set up the panel while on the go.

Without a portable stand, one must tilt their solar panel on another object so it can be angled toward the sun. Depending on the environment, it may not be easy or safe to do so. That’s why Renogy developed the 100W and 200W Eclipse Solar Suitcases. Each suitcase includes built-in stands and a built-in 30A Adventurer PWM Charge Controller, making setup easier. Unlike the older PWM Charge Controllers, the Adventurer features an LCD screen for ease of use and improved monitoring. The new stands allow for easier adjustment by tightening, loosening and angling, so you can be sure to place your panel in direct light. At the moment, the 100W and 200W Eclipse Solar Suitcases are sold out; however, more will be in stock within the next two months.

In the meantime, if you’re looking for a 100W Solar Suitcase, Renogy still has the standard 100W Monocrystalline Suitcase- with or without a built-in charge controller. Like the Eclipse Suitcases, the standard suitcases feature stands and a handle for easy towing. For more information on the new 100W and 200W Renogy Eclipse Solar Suitcases, visit:
