Founded in 2002 as LibertyPak/Optimized Energy Storage, SimpliPhi Power designs and manufactures energy storage and management systems that utilise lithium ferro phosphate (LFP). Based in California, SimpliPhi products combine the LFP energy storage chemistry with proprietary cell and battery architecture, power electronics, Battery Management System (BMS) and assembly methods, for use in the residential, commercial, military, emergency response and film industries. SimpliPhi Power promotes its proprietary management system that further optimises the life-cycle, performance and durability of its batteries.
The 3x SimpliPhi batteries installed at the Battery Test Centre are connected to a SolaX X-Hybrid inverter which charges and discharges the battery.

Testing update: Following the publication of the Battery Test Centre Report 4 – March 2018, SimpliPhi requested a review of the inverter setpoints that were being used for the SimpliPhi battery under test in the trial. SimpliPhi has since advised ITP that the setpoints we have been using are not consistent with SimpliPhi’s revised setpoints for this product. As such, the existing SimpliPhi batteries have been cycled beyond 100% depth of discharge causing excessive wear and tear on the battery pack and resulting in significant capacity fade. This over-discharging of the battery undermines the validity of the capacity fade analysis performed under this. As such, ITP’s test results for the SimpliPhi battery up until now should not be considered a true reflection of the battery’s expected performance.
ITP is dedicated to working with SimpliPhi to provide an accurate representation of their batteries’ capabilities. SimpliPhi will replace the existing batteries with a new set and will be providing an up to date installation manual along with the integration guide for the PHI 3.5 battery and inverter that will be used in the trial to ensure that the new batteries are correctly configured with the inverter.
