AmpliPHI™ 3.8 Battery
The AmpliPHI™ 3.8 Battery utilizes advanced Lithium Ferro Phosphate (LFP) chemistry that eliminates cobalt which reduces the risk of thermal runaway, fire propagation, operating temperature constraints, and toxic coolants to deliver more efficient, safer and reliable energy storage. Designed and built with versatility in mind, the AmpliPHI 3.8 Battery 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, making it an ideal solution for battery replacement, expansion of existing systems, or as a new installation for residential and commercial systems, on and off-grid, scalable up to 60 batteries.
