SimpliPhi Power’s AmpliPHI 3.8™ Battery with communications utilizes the safest Lithium Ion chemistry available, Lithium Ferro Phosphate (LFP). No cobalt or explosive hazards that put customers at risk. By eliminating cobalt, the risk of thermal runaway, fire propagation, operating temperature constraints, and toxic coolants are reduced.


The AmpliPHI features a Battery Management System (BMS) with closed loop communications pre-configured with Sol-Ark inverters that reports SOC and other critical real-time data, optimizing the value of storage and functionality within balance-of-system equipment. Combined with our proven overcurrent protection (OCPD) and accessible 100 Amp DC breaker On/Off switch, installation time is reduced and safety is increased during set-up for residential and commercial systems, on and off-grid. Designed to scale up to 40 batteries, the AmpliPHI will offer pre-configured communications with other inverter manufacturers, to be announced soon.
