The SimpliPhi Power PHI2.6™ Technical Overview:
PHI2.6™ Smart-Tech Battery Safety Protocol and
Protective Features
Safety Protocol:
IMPORTANT NOTE: Circuit Breakers, Disconnects and Fuses should be employed throughout
several points of a power storage and generation installation to eectively 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 PHI2.6™ Smart-Tech Battery contains both an 80 Amp circuit breaker and
an internal BMS with circuitry that protects the Lithium Ferrous Phosphate cells from overcharge, over-
discharge and excessive load amperage, the PHI2.6™ Smart-Tech Batteries must always be installed with a
charge controller and the appropriate settings to protect the PHI2.6™ from open PV voltage and other high
voltage charging sources. The PHI2.6™ Smart-Tech 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) turning the PHI2.6™ 80 Amp breaker “ON/OFF” switch to the “ON” position. Reverse polarity
at the battery terminals will void the Warranty and destroy the batteries.
PHI2.6™ Smart-Tech 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 80 Amp 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.
PHI2.6™ Smart-Tech Batteries do not vent any harmful gasses, and do not require special ventilation
or cooling.
PHI2.6™ Smart-Tech 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 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 PHI2.6™ Smart-Tech Batteries. See MSDS for chemical analyses (Page 23).

CAUTION: Charging LFP batteries at temperatures below freezing.
Do not attempt to charge the battery below 32 F (0 degrees C). Although cold temperatures do not harm
PHI batteries, attempts to charge at subfreezing temperatures can adversely aect SOH and cycle life, and
will void the Warranty. If the battery must be charged below 32 F (0 degrees C), the rate of charge must be
at no more than 5% of the battery’s rated capacity (C/20).
Only use a SimpliPhi approved LFP charger if ancillary charging is required before installation, testing or trou-
bleshooting. Failure to use a SimpliPhi approved LFP charger will damage the battery and void the warranty.
SimpliPhi Power PHI2.6™ Smart-Tech Protective Features:
PHI2.6™ Smart-Tech 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 eciency and freedom from material impurities, toxicity and hazardous risk.
Each PHI2.6™ Smart-Tech Battery contains circuitry that protects the Lithium Ferrous Phosphate cells
from overcharge, over-discharge and excessive load amperage. If the values specified are exceeded, the
protective circuitry will shut down the flow of electricity to/from the PHI2.6™ Smart-Tech 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 PHI2.6™ Smart-Tech
Batteries go into a state of self-protection and shut down the flow of electricity.
In addition, the PHI2.6™ Smart-Tech Battery is equipped with a built in 80 Amp breaker that eectively works
as an “ON/OFF” switch to be used during shipping and installation. The breaker works in conjunction with
the built in battery management system (BMS) and creates additional safety, eciency
and functionality to the overall power storage system.

SimpliPhi Power PHI2.6™ Smart-Tech Battery Performance Parameters
and Sizing Calculations:
PHI2.6™ Smart-Tech Batteries perform at full rated capacity in most operating environments. No increase
in sizing, no special compensations, no burying procedure or insulation needs to be considered when
determining the size of the energy storage and management system under the following circumstances
and conditions.
See specific inverter manufacturer program settings for optimizing system integration
Note: There is less than 1% loss of energy during charging.
PHI2.6™ Smart-Tech Batteries do not need to be de-rated unless running continuously at more than 90%
capacity, at temperatures below 0 degrees Celsius, or above 60 degrees Celsius. To achieve higher cycles
of 10,000+, please refer to operating temperatures and inverter settings on page 16 of the manual. Further
details are available on request from SimpliPhi Power.

Installation Procedure and Diagrams
System Sizing for Your Installation
The number of PHI2.6™ Smart-Tech Batteries should be specified in terms of total storage capacity before
the initial installation based on the goals and objectives of the project. All PHI2.6™ Smart-Tech Batteries
are balanced during final production and testing stages. Following proper wiring guidelines ensures that a
system will not require any manual balancing processes.
DO NOT COMBINE PHI2.6™ SMART-TECH BATTERIES WITH OTHER
BRANDS OR CHEMISTRIES
DO NOT MIX PHI SMART-TECH BATTERIES FROM DIFFERENT
INSTALLATIONS, CLIENTS, OR JOB SITES
System Configuration - Basic Concepts

PHI SMART-TECH BATTERIES ARE DESIGNED FOR PARALLEL OPERATION ONLY - DO NOT ARRANGE
IN SERIES FOR INCREASED VOLTAGE
System Wiring Basics
Refer to published electrical wiring specifications and ratings. All wire should be an appropriate gauge and
construction to handle the loads that will be placed upon it. Heavy gauge, high strand copper wire is the
industry standard due to its stability, eciency and overall quality. A qualified installer should understand
this and must adhere to the industry standard and published electrical guidelines.
For All Installations
• Maintain identical wire lengths from each PHI2.6™ Smart-Tech Battery terminal to the common bus.
• Use identical wire construction from each PHI2.6™ Smart-Tech Battery terminal to the common bus.
All PHI2.6™ Smart-Tech Batteries are outfitted with an 80A hydraulic/magnetic circuit breaker which will
show a white base when tripped. This breaker increases safety during installations and allows the battery
to eectively be turned “o” or “on.”
All PHI2.6™ Smart-Tech Batteries are designed to serve at a fixed voltage range in parallel arrangements for
maximum available amperage and storage capacity. PHI2.6™ Smart-Tech Batteries are not
designed to be arranged in series for increased voltage. Series arrangements can result in damage to
the Smart-Tech Battery’s protective circuitry and will void the Warranty.

Simple Parallel Arrangements
Storage Capacity and total available Amperage is increased by Parallel arrangements. The following
illustration shows two PHI2.6™ Smart-Tech Batteries in Parallel. For example, assume that these are 24V
Smart-Tech Batteries.
Note the overall Voltage range is not changed. The arrangement remains at 24 Volts, the available AH
capacity, or ability to provide 24 Volt power over time, has been doubled. The available amperage from
the system has been doubled. The same configuration should be applied to other parallel arrangements,
whether they are 24V or 48V. See Figure 1.2.

Figure 1.3
Figure 1.3 represents two PHI2.6™ Smart-Tech Batteries in Parallel. Wire lengths from PHI Smart-Tech
Batteries should be identical in length and gauge in order to balance the load across both (all) PHI Smart-
Tech Batteries in the installation. Identical wiring length is a critical feature of parallel power storage
systems that must be adhered to throughout all parallel wiring instructions.

Increasing Capacity with Parallel PHI Smart-Tech Battery Configurations
Special attention should be paid for parallel installations. Correct wiring is essential to insure optimum
performance and system longevity. All wire “runs” should utilize identical wiring gauge and identical wire
lengths between PHI2.6™ Smart-Tech Batteries and the common negative or positive “Bus” or Load.
Figure 1.4
Figure 1.4 depicts one of four PHI2.6TM Smart-Tech Batteries that will have been wired in Parallel. The wiring
arrangement will be repeated to connect all four Smart-Tech Batteries in parallel. The completion of this
configuration will require 8 identical lengths of appropriately heavy gauge copper wire.
Alternate wiring schemes are also eective. The “Cross Diagonal” method is perhaps less common but
has been evaluated in outside facilities and found to be very eective. The Cross diagonal method can
minimize copper wire runs to a degree and can also serve as a tool in complex wiring schemes where
space is at a minimum or system layouts are complex or irregular. For more information on cross diagonal
wiring methods, and the benefit of correct wiring configurations, refer to:
http://www.smartgauge.co.uk/batt_con.html
Use identical length and gauge wire to balance the load across the batteries.
Helpful Tips:
• Determine the cable length for the battery terminal farthest from the bus.
• Make all Battery cables a matching length.
• Additional cabling or slack that remains with the shorter distance runs can be coiled
and secured with Zip Ties.

KEY POINTS
1. Each PHI2.6™ Smart-Tech Battery contains circuitry that protects the Lithium Ferrous Phosphate
cells from overcharge, over-discharge, excessive charge and load amperage. If the values
specified are exceeded, the Smart-Tech Batteries will enter a protective shut down state. In some
cases this will result in the need to re-initialize an inverter charger or other pieces of equipment in
the installation. 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 among most inverter
chargers. Check your inverter manufacturer specifications.
2. If PHI2.6™ Smart-Tech Batteries enter a self protective mode, negligible voltage readings will be
present until the units reset. In some instances, after a prolonged shut down, a charge might need
to be manually applied to the energy storage bank. Should this occur, please contact SimpliPhi
Power for technical support. The PHI Smart-Tech batteries are designed to remain robust and safe
under most circumstances.
3. Although each PHI2.6™ Smart-Tech Battery contains circuitry that protects the Lithium Ferrous
Phosphate cells from overcharge, over-discharge and excessive load amperage, the PHI2.6™
Smart-Tech Batteries must always be installed with a charge controller and the appropriate settings
to protect the PHI2.6™ from open PV and other high voltage sources. The PHI2.6™ Smart-Tech
Battery alone will not protect the batteries from these extreme electrical phenomena.
4. GRID TIED SYSTEMS: Once the PHI2.6™ Smart-Tech Batteries have been installed, turn on the
entire system to test, but once testing has been completed please disconnect the PHI2.6™
Smart-Tech Battery Bank from the load center until your local Utility Inspector is ready to
turn on the entire system. The charge controllers and inverter monitoring systems can drain the
PHI2.6™ Smart-Tech Batteries over an extended period of time when the entire system is not fully
operational due to the electrical draw of the system components.
5. OFF GRID SYSTEMS: Do not connect the PHI2.6™ Smart-Tech Batteries until the entire system is
ready to turn on and is fully operational. Install with the 80 Amp breaker in the “OFF” position.
6. See Charge Controller Settings in the Appendix of this manual. PHI2.6™ Smart-Tech Batteries are
compatible with almost all Inverter Chargers and Charge Controllers. Please contact SimpliPhi
Power for recommended settings for any device not expressly covered in this manual.
7. 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 battery and void
the warranty.
8. CAUTION: Charging PHI LFP batteries at temperatures below freezing.
Do not attempt to charge the battery below 32 F (0 degrees C). Attempts to charge at
subfreezing temperatures can adversely aect SOH and cycle life, and will void the warranty.
If the battery must be charged at temperatures below freezing the rate of charge must be at no
more than 5% of the battery’s rated capacity (C/20).

The right hand stud resides in a red colored high temperature molded insert. This connection is for the
positive lead. The left hand stud resides in a black colored high temperature insert. This connection is for
the negative lead. 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.

SimpliPhi Power, Inc. | 420 Bryant Circle | Ojai, CA 93023, USA | [phone] | [e-mail] | SimpliPhiPower.com
| 15 |
Connecting Cable Leads to the PHI2.6™ Smart-Tech
Batteries:
NOTICE: SPARK MAY BE PRESENT WHEN CONNECTING WIRES TO PHI2.6™ TERMINALS
A brief small spark is often present when connecting the second of two leads to a battery. Example: If the
Positive has been connected, a small spark will likely be present when connecting the Negative lead. This
is a normal occurrence. Complete all connections in a clean, ventilated, well lit area. To avoid any spark or
electrical event when connecting the terminal leads on the PHI2.6™ Smart-Tech Battery, turn the 80 Amp
breaker “ON/OFF” switch to “OFF” position.
Power Cabling for the PHI2.6™ Smart-Tech Battery is not included. Your qualified installer or application
specifications will determine the wire gauge for your system.
Considerations for Power Cable Terminations
- PHI2.6™ Smart-Tech Battery Mounting Stud Size: 3/8’’
- Power Cable Wire Gauge: Generally anywhere from 6 AWG to 2/0 AWG or larger.
High amperage rated ring terminals can be found for these and other common dimensions. Your installer
can source these or we can provide them based on the specifications you provide.
Protection from the Environment
Anticorrosive compounds or epoxies are occasionally used in harsh or marine climate installations. Please
contact your Electrician or Qualified Installer to determine if this is advisable, and if so, what solution best
suits your application.
Final Connection of the Installation
Final installation and operation guidelines will be dictated by your Electrician and Installer based on the
overall properties of and procedures for the equipment in your installation and any code requirements
that apply to your region. SimpliPhi Power, Inc. technicians and sales sta are available to provide any
additional information on the PHI2.6™ Smart-Tech Battery as needed. Please contact SimpliPhi Power for
any technical support at your convenience. SimpliPhi Power, Inc. is committed to providing safe, reliable
energy storage and management that is maintenance free, non-toxic and long-lasting. This commitment
extends to our customers, valued installers, partners, and to the community at large. Please be aware
of the potential electrical hazards before interacting with any and all electrical or mechanical devices.
Please take all necessary precautions in your projects and installations. Please refer to page 4 for safety
guidelines.
PHI Smart-Tech Batteries feature a Low Battery Voltage Cut O (LBCO). This is a self protection mechanism
that prevents over discharge. The LBCO will cause the battery to turn o once batteries approach Zero
Capacity or 100+ percent depth of discharge.

SimpliPhi Power, Inc. | 420 Bryant Circle | Ojai, CA 93023, USA | [phone] | [e-mail] | SimpliPhiPower.com
| 16 |
Most, if not all, inverters have related features. These features are often referred to as “Load Disconnect”,
“Load Shedding” or similar. These features are there to protect the battery bank from excessive discharge.
In instances of low battery voltage, when there is no incoming energy to recharge the battery bank, the
inverter will disconnect the load and remain in standby until the battery bank is recharged.
For O Grid installations, where charge energy is only provided by PV arrays, Inverter “Load Disconnects”
are generally set at a value that will allow a system to remain online and in standby for at least 24 hours
(10% at top of charge and 10% at bottom of charge). This allows a system to stay online until at least one full
day of sun can recharge the battery bank.
In any application, o-grid or grid-tied, if your PHI2.6™ battery bank is reaching the LBCO, load disconnects
or load shedding set points may need to be adjusted.
In case of LBCO, cycle the DC Battery Disconnect (inverter), in order to reset the system. Only complete
this procedure when there is a charge source available, otherwise, the system will simply reach LBCO in a
short time period and shut down again.

PHI2.6™ Smart-Tech Battery Units
Safety Attributes and Certifications/Green Characteristics
SAFETY ATTRIBUTES AND CERTIFICATIONS
Intrinsically Safe Operation and Installation
The PHI Lithium Ferrous Phosphate (LFP) battery cell component is made with an intrinsically safe cathode
material (iron phosphate). This creates a strong molecular bond, which withstands extreme conditions,
prolongs cycle life, and maintains integrity with little or no maintenance over extended periods of time.
There is virtually no danger of Thermal Runaway, as there may be with Lead Acid, NiCd, and Lithium Cobalt
type batteries. No venting or cooling is required. No precautions or special structural considerations are
necessary when installing PHI2.6™ Smart-Tech Batteries.
There are No Safety Hazards due to O-Gassing, Exposure to Acids or Thermal Runaway as there are
with Lead Acid AGM type batteries
PHI2.6™ Smart-Tech Batteries do not vent dangerous gasses, such as hydrogen and oxygen, because there
are no chemicals used in the creation of the electrical energy, in contrast to Lead Acid and other battery
chemistries. There are no dangers of exposure to sulfuric acid because PHI2.6™ Smart-Tech Batteries do
not have caustic electrolytes. Thermal runaway is not an issue with PHI products due to the basic nature of
Lithium Ferro Phosphate cell chemistry utilized in all our power storage products.
PHI2.6™ Smart-Tech Battery Control and Protective Circuitry
SimpliPhi Power Inc. utilizes balancing, voltage regulation, thermal, current controls, as well as other
protective measure, in its PHI2.6™ Smart-Tech Battery Management System (BMS). This protective circuitry
is embedded in the architecture of each PHI2.6™ Smart-Tech Battery.
UN DOT Certified Cells
The Lithium Ferrous Phosphate (LFP) cells are independently certified to withstand the UN DOT T1-
T8 testing guidelines with no special circuitry added. These tests include short circuit, over-voltage,
overcharging, extreme temperature, high altitudes, shock and extreme vibration testing.
UL Compliance
The Lithium Ferrous Phosphate cells within the PHI2.6™ Smart-Tech Batteries fully comply with the safety
testing parameters of UL 1642.
RoHS Compliant
SimpliPhi Power Smart-Tech Batteries are RoHS compliant. Any RoHS compliant component is tested for
the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated
biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). For Cadmium and Hexavalent chromium,
there must be less than 0.01% of the substance by weight at raw homogeneous materials levels. For
Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw
homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the
mercury must not have been intentionally added to the component. In the EU, some military and medical
equipment are exempt from RoHS compliance.
