determined by established standards and evaluated by certified electricians, licensed installers,
and regional code authorities. Although each PHI Battery contains an internal BMS with circuitry
that protects the Lithium Ferrous Phosphate cells from overcharge, over-discharge and extreme
load amperage, the PHI Batteries must always be installed with a charge controller and the
appropriate settings to protect the PHI Battery from open PV voltage and other high voltage
charging sources. The PHI Battery Management System (BMS) and internal circuit breaker alone
will not protect the PHI Batteries from these extreme electrical phenomena. Failure to adhere to
installation protocol will void the Warranty.
CAUTION:
Verify polarity at all connections with a standard volt meter before 1) energizing the
system and 2) on batteries with threaded stud connections, before switching the circuit breaker to
the “ON” position.
Reverse polarity
at the battery terminals will void the Warranty and destroy
the PHI Batteries.
PHI 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. For batteries
with threaded strud connections, be sure the built-in breaker is in the “OFF” position to minimalize
the risk of shock or sparks during the installation and commissioning of the system. Use of
insulated gloves, clothing and footwear is always recommended when working in close proximity
to electrical devices. Cover, restrain or remove jewelry or conductive objects (metal bracelets,
rings, belt buckles, metal snaps, zippers, etc.) when working with any electrical or mechanical
device. Cover or restrain long hair and loose clothing when working with any electrical or
mechanical device.
PHI Batteries do not vent any harmful gasses, and do not require special ventilation or cooling.
PHI Batteries are not capable of thermal runaway. As with any battery, if the cells are severely
damaged due to physical abuse, reverse polarity, high voltage, unmitigated current or other
electrical phenomenon incurred outside of Warranted 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 PHI LFP
Batteries’ electrolyte and other material components generate a limited amount of heat and do
not go into a state of “thermal runaway” or propagate fires. The SimpliPhi UL 1973 Battery
Certification verifies “No Thermal Runaway”. See MSDS for chemical analyses.
1.2.2 – Charging at Temperatures Below Freezing
It is important to take necessary steps to determine the temperature of the PHI Battery prior to
charging the battery, as the battery may otherwise be adversely impacted.
CAUTION:
Do not attempt to charge the PHI Battery below 32° F (0° C). Although cold
temperatures do not harm PHI Batteries, attempts to charge at subfreezing temperatures can
adversely affect SOH and cycle life, and will void the Warranty. If the PHI Battery must be
charged below 32° F (0° C), the rate of charge must be at no more than 5% of the PHI Battery’s
rated capacity (C/20).
CAUTION
:
Only use a SimpliPhi approved LFP charger if ancillary charging is required before
installation, testing or troubleshooting. Failure to use a SimpliPhi approved LFP charger will damage
the PHI Battery and void the Warranty. See Appendix C for more details on approved chargers.
1.2.3 – Battery Management System (BMS)
PHI Batteries are manufactured utilizing Lithium Ferrous Phosphate (LFP) cells, which are
produced under exclusive patented licensed technologies, as well as proprietary materials,
architecture, manufacturing processes and battery management system (BMS). This assures the
highest grade and quality, longest cycle-life, greatest efficiency and freedom from material
impurities, toxicity and hazardous risk.
