1.2.2 – Charging at Temperatures Below Freezing
It is important to take necessary steps to determine the temperature of the PHI 2.7 Battery prior to
charging the battery, as the battery may otherwise be adversely impacted.
CAUTION
:
Do not attempt to charge the PHI 2.7 Battery below 32
°
F (0
°
C). Although cold
temperatures do not harm PHI 2.7 Batteries, attempts to charge at subfreezing temperatures can
adversely affect SOH and cycle life, and will void the Warranty. If the PHI 2.7 Battery must be
charged below 32
°
F (0
°
C), the rate of charge must be at no more than 5% of the PHI 2.7
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 2.7 Battery and void the Warranty.
1.2.3 – Battery Management System (BMS)
PHI 2.7 Batteries are manufactured utilizing Lithium Ferrous Phosphate (LFP) cells, which are
produced under exclusive patented licensed technologies, as well as proprietary materials,
architecture, assembly methods 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.
Each PHI 2.7 Battery contains circuitry that protects the Lithium Ferrous Phosphate cells from
overcharge, over-discharge and extreme load amperage. If the values specified are exceeded,
the protective circuitry will shut down the flow of electricity to/from the PHI 2.7 Batteries. In some
cases, this will result in the need to re-initialize an inverter charger. Often, inverter system
settings will be saved within the inverter memory storage and will not need to be reset. This is not
an absolute standard but is common amongst most inverter chargers and should be anticipated if
the PHI 2.7 Batteries go into a state of self-protection and shut down the flow of electricity. Refer
to SimpliPhi’s inverter integration guides for inverter charge controller settings or contract the
inverter manufacturer directly.
1.2.4 – PHI 2.7 Battery Connection Terminals
The PHI 2.7 Batteries are equipped with two 3/8’’ threaded studs with a lock washer and nut. The
red colored high temperature molded insert connection is for the positive lead. The black colored
high temperature insert connection is for the negative lead.
CAUTION:
Do not attempt to loosen the large brass nut at the base of the terminals.
CAUTION:
Do not reverse polarity. It will void the Warranty. Use a volt meter to check polarity before
connecting terminals.
Water Resistant Cable Boots are also included and will be in place when your units arrive. The
boots are to be placed over the cable terminations and will stretch to form a water-resistant seal
around the base of the molded inserts and terminal connections.
1.3 – Explosive Gas Precautions
This equipment is not ignition protected. To prevent fire or explosion, do not install this product in
locations that require ignition-protected equipment. This includes any confined space containing vented
batteries, or flammable chemicals such as, natural gas (NG), liquid petroleum gas (LPG) or gasoline
(Benzine/Petrol).
