SimpliPhi Power

What SimpliPhi Power does

SimpliPhi Power is an Ojai, California-based provider of lithium-ion battery energy storage solutions, founded in 2001 and operating today as a battery storage brand within the Briggs & Stratton Energy Solutions portfolio. Its core product is the SimpliPHI 6.6 Battery, a Lithium Iron Phosphate (LFP)-based stationary storage unit positioned on durability and longevity, with supporting hardware categories including home hybrid inverters and the EnergyTrak remote monitoring platform for battery and generator telemetry. End applications span residential backup power, time-of-use bill management, solar self-consumption, off-grid living, and grid sell-back, alongside commercial use cases in backup power, energy arbitrage, demand response, and off-grid power.

The business sells exclusively through Briggs & Stratton's authorized dealer and installer network across the United States, with go-to-market supported by installer training programs (Elite IQ Installers Program, Power Academy), a closed-loop LFP battery recycling program, and inverter integration partnerships that broaden compatible system architectures. Customers are segmented into residential homeowners (primary) and commercial businesses, with the dealer channel serving both SMB/individual and commercial buyers. Pricing is not publicly disclosed and appears to be quote-based through the dealer network.

The company is privately held and parented by Briggs & Stratton; its single disclosed funding event was a $2.0 million round in August 2016 from two investors. Headcount is reported in the 11–50 range. Leadership includes CEO Catherine Von Burg and CTO/founder Stuart Lennox. No revenue, ARR, or unit-shipment figures are publicly available, and there is no evidence of in-house AI/ML capability beyond standard product telemetry.
