with you and your installation team to achieve a safe, reliable storage system that will provide years of
maintenance free service.
4.1.1 – 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, efficiency 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 PHI Battery terminal to the common bus.
•
Use identical wire construction from each PHI Battery terminal to the common bus.
All PHI Batteries are designed to serve at a fixed voltage range in parallel arrangements for
maximum available amperage and storage capacity.
PHI Batteries
are not
designed to be
arranged in series for increased voltage
. Series arrangements can result in damage to the PHI
Battery’s protective circuitry and
will void the Warranty
.
4.1.2 – Increasing Storage Capacity & Simple Parallel
Arrangements
Storage Capacity
and total available
Amperage
is increased incrementally with the number of
units in Parallel
arrangements. The following illustration (
Figure 4.0
) shows two PHI Batteries in
Parallel
. For example, assume that these are 24V PHI 3.8 Batteries.
Note:
The overall Voltage range is not changed. For this example, the arrangement remains at
24 Volts, while the available AH capacity (ability to provide 24 Volt power over time) has been
doubled with the addition of a second PHI 3.8 Battery. The same configuration and calculation
should be applied to other parallel arrangements, whether they are 12V, 24V or 48V. See Figure
4.0.
CAUTION:
PHI Batteries are designed for parallel operation only. Do not arrange in series for
increased voltage. Wiring in series will void the Warranty.
