Figure 1.0 - PHI 2.7 kWh 48V Circuit Breaker
CAUTION:
Circuit Breakers, Disconnects and Fuses should be employed throughout several
points of a power storage and generation installation to effectively isolate and protect all
components of the system to safeguard against faults, short circuits, polarity reversals or a failure
of any component in the overall system. Fuses, breakers, wiring ratings and values should be
determined by established standards and evaluated by certified electricians, licensed installers,
and regional code authorities. Although each PHI 2.7 Battery contains both a circuit breaker and
an internal BMS with circuitry that protects the Lithium Ferrous Phosphate cells from overcharge,
over-discharge and extreme load amperage, the PHI 2.7 Batteries must always be installed with a
charge controller and the appropriate settings to protect the PHI 2.7 Battery from open PV voltage
and other high voltage charging sources. The PHI 2.7 Battery Management System (BMS) and
internal circuit breaker alone will not protect the PHI 2.7 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) turning the PHI 2.7 circuit breaker “ON/OFF” switch to the “ON” position.
Reverse
polarity
at the battery terminals will void the Warranty and destroy the PHI 2.7 Batteries.
PHI 2.7 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. Be sure to
turn the built-in breaker to 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 2.7 Batteries do not vent any harmful gasses, and do not require special ventilation or cooling.
PHI 2.7 Batteries are not capable of thermal runaway. If the cells are severely damaged due to
physical abuse incurred outside of warranted specifications, which can cause electrolyte leakage
and other failures, as with any PHI 2.7 Battery, the electrolyte can be ignited by an open flame.
However, unlike other lithium ion batteries (LCO) there are no hazardous or toxic materials in the
electrolyte or the material components of PHI 2.7 Batteries. See MSDS for chemical analyses
(Appendix A).
