CAUTION: Do not reverse polarity. It will void the Warranty. Use a volt meter to check polarity before
making connections to battery terminals or Anderson Connectors. A brief small spark is often present
when connecting the second of two leads to a PHI Battery terminal. 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, make the connection with the circuit
breaker in the “OFF” position. To avoid any spark or electrical event when connecting batteries
with Anderson Connectors, turn the accompanying equipment off, connect cables with
appropriate battery mating connectors to the equipment, and then make final connections via
connectors to the batteries before turning on the system’s accompanying equipment.
Power Cabling for the PHI Battery is not included. Your qualified installer or application
specifications will determine the wire gauge for your system. Connection to the PHI Battery
should only be made using appropriately sized ring terminals or mating connectors. Your installer
can source these.
Considerations for Power Cable Terminations
Please factor in the below information for power cable terminations:
•
PHI Battery models with threaded studs – Stud Size: 3/8’’
•
PHI Battery models using SB50 Anderson Connectors
o
12V connections are YELLOW
o
24V connections are RED
•
Power Cable Wire Gauge: Generally anywhere from 6 AWG to 2/0 AWG or larger
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.
4.3.2 – 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 staff are
available to provide any additional information on the PHI 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 Section 1 for safety guidelines.
PHI Batteries feature a Low Battery Voltage Cut Off (LBCO). This is a self-protection mechanism
that prevents over discharge. The LBCO will cause the PHI Battery to turn off once batteries
approach Zero Capacity or 100% Depth of Discharge.
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 PHI Battery bank
from excessive discharge. In instances of low battery voltage, when there is no incoming energy
to recharge the PHI Battery bank, the inverter will disconnect the load and remain in standby until
the PHI Battery bank is recharged.
For off grid installations, where charge energy is only provided by renewable energy such as 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).
