Briggs & Stratton® SimpliPHI 6.6 batteries feature a number of advances that make installation easier. They have self-guiding RapidStak™ connectors that integrate power and communications into a single point without wires or DIP switches. The batteries simply stack on top of one another and click into place, making installation easier and more efficient. Assembling a stack of three can be done in five minutes or less.

They are IP65 rated so they can be installed indoors or outdoors with no additional cabinets required. They can be ground- or wall-mounted inside a garage, shed, utility closet or basement or outside on an exterior wall. Plus, the flexibility of using one, two or three batteries per stack means the system can fit into compact spaces.

In addition, the SimpliPHI 6.6 has full closed-loop integration with leading inverters for advanced communication and broad non-communicating compatibility with any 48V lithium-supporting inverter.

"We are pleased to welcome Briggs & Stratton to our supplier portfolio in the US. This partnership reflects our commitment to supporting our customers with a diverse offering of energy solutions. Our focus remains on supporting solar and energy storage installers with reliable, high-quality solutions that empower long-term success," says Ken Lima, CEO of BayWa r.e.'s U.S. Solar Distribution business.

Section 4.4.1) conducted by Element U.S. Space & Defense.

The SimpliPHI 6.6 battery has a 10-year limited warranty and is guaranteed to retain 75% capacity after 10 years.1 Plus, SimpliPHI batteries are backed by Briggs & Stratton's 117 years of experience in power solutions.
