Figure 2.0 - Four PHI 1.3 Batteries in Parallel
Helpful Tips:
•
Use identical length and gauge wire to balance the load across the PHI 1.3 Batteries.
•
Determine the cable length for the PHI 1.3 Battery terminal farthest from the bus.
•
Make all PHI 1.3 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 PHI 1.3 Battery terminals directly to a common bus.

4.2.1 – Connecting Cable Leads to the PHI 1.3 Batteries
Before connecting the cable leads to the PHI 1.3 Battery, please be aware of the following
information concerning power cabling, considerations for power cable terminations as well as
installation environments.
CAUTION:
Spark may be present when connecting wires to PHI 1.3 terminals.
CAUTION:
Do not reverse polarity. It will void the Warranty. Use a volt meter to check polarity before
connecting terminals. A brief small spark is often present when connecting the leads to a PHI 1.3
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 spark or electrical event when connecting the terminal
leads on the PHI 1.3 Battery, turn the equipment off, connect cables with appropriate battery
mating connectors to the equipment and make final connections to the batteries.
Power Cabling for the PHI 1.3 Battery is not included. Your qualified installer or application
specifications will determine the wire gauge for your system. Connection to the PHI 1.3 Battery
terminal should only be made using appropriate mating connectors. Your installer can source
these.
