At Shop Solar Kits, our selection of Simpliphi batteries is among the highest-rated items we carry. So, naturally, we field a lot of questions about the company and its offerings. In this article, we dive deep into the ins and outs of SimpliPhi Power and highlight some of its best products. 

Who is SimpliPhi Battery?

SimpliPhi Power is a lithium iron phosphate battery manufacturer based in the United States. Stuart Lennox founded the company. At the time, he was a designer in film and television. With a combination of high-quality products and Lennox’s ties within the entertainment industry, many small off-grid power applications in equipment and sets used SimpliPhi's early products in many Hollywood productions.

Notably, SimpliPhi’s batteries are famous for powering the lighted suits in Tron Legacy and the three-dimensional moon in the background of TBS’s Conan. Today, SimpliPhi is an internationally recognized brand that sells a few lines of lithium-based electricity storage solutions.  

How Long Has SimpliPhi Been in Business?

SimpliPhi has been in business since 2002, first operating under the name LibertyPak. In 2010, founder Stuart Lennox teamed up with Catherine Von Burg to create the Optimized Energy Storage (OES) product line. The pair rebranded the company as SimpliPhi, which references the Greek mathematical symbol Phi, known for balance, symmetry, and simplicity.

Where are SimpliPhi Batteries Made?

Simpliphi manufactures and ships its products from facilities in Oxnard, California.

Why Should I Buy a SimpliPhi Battery? 

For most people, a SimpliPhi battery is a large investment, so it is crucial to understand the benefits of purchasing one. Above all, SimpliPhi batteries are high-quality products with great warranties, rightfully recognized by some of the industry’s leading names. 

High-Quality Products

SimpliPhi batteries utilize a Lithium Iron Phosphate (LiFePO4 or LFP) system, a specific type of lithium-ion technology.  The LFP batteries from SimpliPhi are optimized with proprietary cell architecture, power electronics, BMS, and manufacturing methods that allow for lightweight and attractive installations.  

In most cases, you can replace an old acid battery with a similarly sized SimpliPhi LFP battery. In doing so, you enjoy a maintenance-free electricity storage experience that is lighter and more efficient that also offers a higher discharge capacity.  

Industry Leading Warranties

When you purchase a SimpliPhi product, you can rest easy knowing that your battery is guaranteed to last. Although the lifespan may differ slightly between its products, most SimpliPhi batteries have 10-year warranties at 90% capacity (up to 5,000 cycles) or 80% capacity (up to 10,000 cycles). For specific SimpliPhi product warranties, read the downloadable product documents on its website

Highly Recognized Products and People

Although there are many lithium-ion battery manufacturers, few are as well-recognized for the quality of their products as SimpliPhi. Solar Power World awarded SimpliPhi with honors for the “Top Solar Storage Products” for both small and large-scale applications. Additionally, the company’s CEO participated in an exclusive accelerator program for social entrepreneurs sponsored by the U.S. Department of State.  

What are SimpliPhi Power's Most Popular Products?

Whether you are a first-time DIYer tinkering with a few hundred watts of solar energy or you need a full-home, utility-grade power system, there is probably a SimpliPhi battery for you. Below, we showcase some of the most popular batteries from SimpliPhi’s product lines.  

PHI Core Power Batteries

SimpliPhi’s “PHI” brand batteries are great for storing energy in a 12V, 24V, or 48V solar energy system. The batteries do not require ventilation, cooling, or thermal regulation and can easily drop in to replace an existing lead-acid battery. They use non-toxic and non-hazardous recyclable materials and are compatible with all industry-standard inverter/charger controllers.  

The 2.7kWh “low profile” model PHI battery is an extremely sleek, lightweight, and compact model that is great for RVs or stacking multiple in-home units. Both the 24V and 48V models are 17.5 x 14 x 5 inches and weigh only 61 pounds. PHI batteries have an operating efficiency of 98% and can discharge their entire watt-hour capacity without damaging the system.

PHI High Output Batteries

If you need more power, SimpliPhi also manufactures high-output batteries that discharge at more than double the amperage of its other batteries. Take, for example, this 1.2 kWh battery, which has a continuous output capacity of 160 amps. Combined with the right inverter, this creates an immense amount of power potential. If you have any questions about your particular solar system, feel free to contact us. However, if you plan on utilizing SimpliPhi’s industry-leading batteries, we highly recommend using one of its all-in-one systems, such as the AccESS.  

AccESS™ Schneider and Sol-Ark 

It doesn’t get much better than the SimpliPhi AcceSS when it comes to home power storage and delivery, AccESS systems feature outdoor-friendly casing and have everything you need for the best home solar experience. The smart system features either a Scheider or Sol-Ark inverter and automatically disconnects from the grid in a power outage. Day to day, you can program it to optimize self-consumption of battery power to minimize any dependence on grid-powered energy.

Each AccESS system comes with an easy-to-use remote monitoring system, and you can install it with a built-in MPPT solar charge controller. Because no two homes are the same, we sell AccESS systems with several different capacities and capabilities. Depending on your needs, we recommend:

Big Genny Batteries 

Big Genny Batteries are a portable source of AC power designed to bring a large amount of electricity to a remote location during an emergency or blackout. The portable power station is packed with a 1,240-watt-hour battery and a 1000 watt inverter, making it possible to run lights, fans, and small appliances for hours simultaneously.  

Each Big Genny battery has a hard-shell, weather-resistant case with a collapsible handle and wheels for easy transportation. The system also has two built-in AC wall plugs as well as two USB ports for powering a variety of devices.   

To charge a Big Genny, you can plug it into your home’s power outlet or connect it to a generating source of energy, like wind or solar. If you want an all-in-one purchase, the Big Genny Emergency Kit comes with a 200W foldable array of solar panels, making it possible to use the system continuously.  

Little Genny Batteries 

As you may expect from the name, a Little Genny Battery is a lot like a Big Genny Battery but smaller. In fact, it’s a lot smaller. The Little Genny weighs only 12 pounds (5 kg), under a third of the weight of the 45-pound Big Genny.  

This small size means that the Little Genny has a limited storage capacity of just 322 watt hours and a maximum output of just 300W. That said, in a pinch, the unit can provide nearly 50 hours of cell phone charging, 30 hours of 10W LED lights, or even seven hours of power for a small refrigerator.  

Likewise, the Little Genny Emergency Kit comes with an 80W foldable solar array weighing a mere 4.8 pounds. With 300W of continuous output capacity and a total weight of about 16.8 pounds, the Little Genny Emergency Kit is a great solution for a continuous supply of solar power for phones, tablets, fans, and more.  

Final Words

Simpliphi is a leader in high-powered solar storage for a reason. It makes quality products at affordable prices and is located right in the United States. Simpliphi has built its reputation on products that look great and are very efficient and reliable. If you still have questions, don't hesitate to reach out!
