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 PHI 3.5 Batteries and the common negative or positive
“Bus” or Load. Figure 3.0 depicts four PHI 3.5 Batteries that have been wired in Parallel. This
configuration requires
8 identical lengths of appropriately heavy gauge copper wire
.

Helpful Tips:
•
Use identical length and gauge wire to balance the load across the batteries.
•
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.
Wiring Methods:
1. For 1 to 8 units: Wire directly to inverter & charge controller equipment.
2. For 6 to 20 units: Use a DC combiner or panelboard.
3. For 20+ units: Connect the battery terminals directly to a common bus.
Section 2.3 – Torque Values
For the DC terminals on the PHI 3.5, torque bolts to 160-in lbs (13.3 ft-lb).
Section 2.4 – Mounting Hardware
The SimpliPhi Power Mounting Brackets (sold separately) are designed to secure one PHI 3.5 Battery to
a load bearing surface. SimpliPhi Power Batteries can be mounted in practically any orientation
(Terminals Up or on any Side), with no impact to the performance of the battery. Do not install them
upside down. The brackets can be mounted directly to a wall or can be arranged on strut channels for
