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 manufacturing methods to create safe, reliable, durable and highly scalable on-demand power solutions. Available for the residential, commercial, military and emergency response markets, SimpliPhi storage solutions have been rigorously tested and passed operational performance requirements by the U.S. Army and Marine Corps. Integral to all SimpliPhi solutions is a proprietary management system that further optimizes the life-cycle, round-trip efficiency rate, performance and durability of its batteries. SimpliPhi PHI 3.5 kWh 48V 60 Amp batteries are Certified to UL 1973 Standard.

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
System monitoring by system control panel or Combox with remote system monitoring by web browser or mobile device app
No cobalt , thermal regulation, cooling, or risk of fire
Extended operating temperature
System control panel or Combox
Solar MPPT for DC-coupled or off-grid installations
Automatic Generator control for additional standby power


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

Disaster recovery customers: Reliable, 98% efficient, non-toxic backup power in the event of a power outage
