1.3 – Product Overview
The SimpliPHI deep-cycle Lithium Ferro Phosphate (LFP) Battery is optimized with proprietary cell
architecture, power electronics, Battery Management System (BMS) with communications, manufacturing
materials and processes. This assures the highest grade and quality, longest cycle-life, greatest efficiency and
freedom from material impurities, toxicity and hazardous risk. The SimpliPHI Battery is modular, lightweight
and scalable. It provides power security and seamless integration of renewable and traditional sources of
energy in conjunction with or independent of the grid.
1.3.1 – Battery Management System (BMS)
Each SimpliPHI Battery contains circuitry that protects the LFP cells from damaging conditions
(overcharge, over-discharge, extreme load amperage, etc.). If pre-programmed BMS values are
exceeded, the protective circuitry will shut down the flow of electricity to/from the SimpliPHI Battery.
In some cases, the BMS will automatically resume the flow of electricity to/from the SimpliPHI Battery
when the battery is no longer in damaging conditions. In other cases, the SimpliPHI Battery’s self-
protection mechanism will result in the battery’s breaker tripping and requiring a manual re-set (refer
to Section 6.0 - Troubleshooting of this Manual for manual re-set instructions).
Regardless, once SimpliPHI Battery operation resumes and the connected inverter is back on,
SimpliPhi recommends checking that the inverter’s settings are still correct. Often, inverter system
settings will be saved within the inverter memory storage and will not need to be reset. However, refer
to SimpliPhi’s SimpliPHI Integration Guides for inverter and/or charge controller settings to verify the
set-point values. (https://simpliphipower.com/product-documentation/
