Overview
Simpliphi AmpliPHI 3.8kWh Battery
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.
SimpliPhi Power’s AmpliPHI 3.8™ Battery 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 for industry leading 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 75 batteries, the AmpliPHI integrates seamlessly with Sol-Ark and SMA, with other inverter brands being added soon.
Features:
- CHEMISTRY: Lithium Ferro Phosphate (LFP), safest Lithium Ion chemistry available. No cobalt, risk of thermal runaway or fire
- OCPD: Built-in accessible 100 Amp DC breaker On/Off switch
- BMS: Built-in Battery Management System with Communications
- COMPATIBILITY: Compatible with Sol-Ark, Victron, SMA (pending) & Schneider (pending) Inverters
