BRIGGS & STRATTON ENERGY SOLUTIONS INTRODUCES MORE POWERFUL, MORE AFFORDABLE HOME BATTERY SYSTEM

SimpliPHI® 6.6 Powers Homes Through Power Outages, Creates Energy Resilience

For homeowners looking for reliable, quiet, emission-free backup energy, Briggs & Stratton Energy Solutions is introducing its SimpliPHI® 6.6 Home Battery System. This innovative new battery is more powerful, more affordable, more versatile and more compact than other systems. The SimpliPHI 6.6 uses advanced lithium ferro phosphate (LFP) chemistry and can provide enough power to get a home through a "typical" outage.


Briggs & Stratton's new SimpliPHI 6.6 battery delivers 6.65 kWh of energy and can be installed in stacks of one to three. For increased power, a system can be scaled to six stacks of three with the 18 batteries delivering 119.7 kWh with maximum continuous power of 84 kW.

With the average power outage in the U.S. lasting 5.5 hours1, a one-battery SimpliPHI 6.6 system can meet the needs of many homeowners by delivering more than 10 hours of power at 50% backup load*. The SimpliPHI battery system can be used as an alternative to a standby generator, offering additional installation flexibility and versatility.

In addition to providing backup power during a utility outage, the SimpliPHI 6.6 battery system can be used during peak utility rate times or with demand response programs to lower utility bills. The system can supplement solar energy or be paired with a generator for off-grid power.

"We're breaking new ground with the SimpliPHI 6.6 battery and are continuing to innovate and help homeowners achieve energy resilience and independence," said Tom Rugg, SVP & President - Briggs & Stratton Energy Solutions. "We're also focused on affordability. The SimpliPHI 6.6 battery is 25% less expensive than our competitors, and that is before tax incentives."

The SimpliPHI 6.6 battery stack is extremely versatile and gives homeowners multiple installation options. It is outdoor rated so it can be installed indoors or outdoors with no additional cabinets required. The system can be ground- or wall-mounted inside a garage, shed or basement or outside on an exterior wall. The flexibility of using one, two or three batteries per stack means the system can fit into small spaces.

Aesthetically, the SimpliPHI 6.6 features a sleek design and is more compact and lighter than other systems. Each battery is 17.3" tall by 28.6" wide by 6.7" deep.

On the technology front, the SimpliPHI 6.6 uses LFP chemistry that's been proven to be safer and less prone to thermal runaway. In fact, SimpliPHI batteries have been used around the world for more than a decade in some of the harshest environments. In 2010, the U.S. Department of Defense used SimpliPHI batteries to deliver mission-critical power on Forward Operating Bases in Iraq and Afghanistan.

The LFP chemistry allows for 6,000+ cycles @ 80% DoD with an end-of-life capacity of 75%. An increased discharge rate of .7C to 1C delivers more storage capacity per hour. In addition, an expanded temperature range allows for full operating/discharging rate from -20 ºC to 55 ºC and full charging rate from -10 ºC to 50 ºC.

Tested and certified to the most stringent standards, the SimpliPHI 6.6 battery is UL 1642, UL 1973, UN 3480 and UN DOT 38.3 certified and has gone through UL 9540A fire safety testing. It recently secured its UL 9540 Edition 3 certification as a standalone DC ESS.

The SimpliPHI 6.6 battery is compatible with the SimpliPHIⓇ 6kW hybrid inverter, Sol-Ark® 8K, 12K and 15K inverters, as well as other leading lithium supporting inverters.

How It Works

Each SimpliPHI 6.6 battery system starts with a ground or wall base. The batteries are placed one by one on top of each other and click into place with RapidStak™ technology. Each battery stack is topped with a battery controller. The controller has a series of four lights that indicate the amount of power available from 25% to 100%. Each battery has an individual green light that illuminates when it's powered.

Once the battery installation and commissioning are complete, homeowners can monitor and manage their Briggs & Stratton SimpliPHI 6.6 battery system through the EnergyTrakTM mobile app. All EnergyTrak data is securely stored in the United States.

Briggs & Stratton Energy Solutions is currently taking pre-orders for its SimpliPHI 6.6 battery system.
