SimpliPhi Power designs and manufactures efficient, non-toxic and enduring energy storage and management systems that utilize lithium ferro phosphate (LFP). Based in California, SimpliPhi combines non-hazardous LFP chemistry with its proprietary cell and battery architecture, power electronics, battery management system (BMS) and assembly methods to create safe, reliable, durable and highly scalable on-demand power solutions. Available for the residential, commercial, military and emergency response markets, SimpliPhi Power storage solutions have been rigorously tested and passed operational performance requirements by the U.S. Army and Marine Corp. Integral to all SimpliPhi Power solutions is a proprietary management system that further optimizes the life-cycle, round-trip efficiency rate, performance and durability of its batteries. SimpliPhi Power storage system components are UL certified and the PHI 3.5 kWh 24V and 48V 60 Amp batteries are ETL Certified, UL 1973 Standard.

SIA (Standard Interconnection Agreement) customers: ESS allows for solar PV power to be self-consumed, curtailing PV production to prevent the export of power to the grid. Compatible with both string inverters and micro-inverters. NEM (Net Energy Metering) customers: add standby power and peak-shaving to a new or existing net-metered solar array Off-grid customers: ESS with 4.8 kW Solar MPPT combines power generation and energy management in a single package

Pre-programmed ESS for backup power, peak-shaving, and self-consumption of solar PV

Internal transfer switch automatically disconnects from the grid during power outages and provides standby power for critical circuits
Outdoor rated enclosure can be free-standing, or pad-mounted
Advanced LFP batteries with a 10,000 cycle / 10-year warranty
98% round trip efficiency
