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/).

2.0 –Safety
For safety reasons, read all instructions and cautionary markings on the SimpliPHI Batteries, and all
appropriate sections of this manual. Failure to follow instructions provided in the Installation Manual,
Integration Guides and/or Warranty will Violate the terms of the Warranty and damage the batteries.
2.1 – General Safety Instructions
•Do not operate if the SimpliPHI Battery has been damaged in any way during shipping or on-site.
•To reduce the chance of short-circuits, always use insulated tools when installing or working with
SimpliPHI batteries or other electrical equipment.
•Remove personal metal items such as rings, bracelets, necklaces, and watches when working with
SimpliPHI batteries and electrical equipment. Wear insulated gloves and rubber shoes.
•SimpliPHI Batteries pose some risk of shock or sparking during the installation and initial wiring and
connection process. This is consistent with all other battery-based storage formats. To minimize the
risk of shock or sparks during the installation and commissioning of the system, make sure the built-in
breaker is in the “OFF” position.

|
REV202207071617
•To avoid a risk of fire and electric shock, make sure that existing system wiring is in good condition and
that the wire is not undersized. Do not operate the SimpliPHI Battery in conjunction with damaged or
substandard wiring or balance of system equipment.
These safety precautions are in addition to the Warnings previously outlined on page 4 of this Manual.
2.2 – Response to Emergency Situations
As with any battery, if the SimpliPHI Battery’s cells are severely damaged due to physical abuse, reverse
polarity, high voltage, unmitigated current or other electrical phenomenon incurred outside of Warranted
installation specifications, it can cause electrolyte leakage and other failures. The electrolyte can be ignited by
an open external flame. However, unlike other lithium-ion batteries with cobalt oxides (e.g. LCO, NCM and
NCA), the SimpliPHI LFP Batteries’ electrolyte and other material components generate a limited amount of
heat and do not go into a state of thermal runaway with fire propagation. The SimpliPhi UL 1973 Battery
Certification verifies “No Thermal Runaway” (see MSDS for chemical analyses). Additional fire safety testing
was conducted through UL 9540A protocols which has demonstrated that SimpliPHI batteries do NOT go into
unmitigated thermal runaway, fire propagation or deflagration when installed in properly operating systems
per this manual.
While SimpliPHI Batteries do not go into thermal runaway with fire propagation, the following protocol should
be followed in the event that the SimpliPHI Batteries are subjected to electrical fire caused by other system
components or failures:
•Ensure that the system is no longer energized, either from the solar array or the grid (main
disconnect).
•Separate any external cables from batteries if present (cut if necessary) using insulated tools.
•Wear a respirator or dust mask to avoid inhaling soot/dust.
•Wear insulating and abrasion-resistant gloves (if permeable, over nitrile or similar gloves).
•Move battery debris into non-conductive bins capable of handling the weight.
•Dispose as regulations require.
CAUTION: While water is an acceptable and effective extinguishing agent for the SimpliPHI
Battery model, the Balance of System equipment used in conjunction with the SimpliPHI
Batteries may require specialized extinguishers such as FM-200 or CO2 suppression systems.
3.0 – Pre-Installation
3.1 – SimpliPHI Battery Performance
SimpliPHI Batteries do not need to be de-rated unless running continuously at more than 90% capacity. To
achieve the greatest cycle life of 10,000 cycles, it is recommended that the SimpliPHI Batteries are operated at
80% maximum Depth of Discharge.
Due to the SimpliPHI Battery’s internal self-protection mechanisms, the battery will not charge when internal
battery temperatures are below 32° F (0° C), will not discharge when internal temperatures are below -4° F (-
20° C), and will not charge or discharge when internal temperatures exceed 158° F (70° C).
All SimpliPHI Batteries are balanced during final production and testing stages. Following proper wiring
guidelines and fully charging the SimpliPHI batteries prior to applying loads ensures that a system will not
require any manual balancing processes.
