• 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.
