Helpful Tips:
Power cabling for paralleling AmpliPHI Batteries is not included. 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.
Each PHI Battery’s individual wire runs are typically sized at 4 AWG, according to the 80A
built-in breaker.
o
Conductor ampacity can be determined using National Electrical Code tables.
o
Depending on the electrical code of the local Authority Having Jurisdiction (AHJ), the
AmpliPHI Battery leads’ gauge may need to be sized according to the built-in breaker
or according to the AmpliPHI Battery’s surge rating.
o Battery cables from Spartan Power are flexible and easy to work with:

also sell battery cables. Refer to the SimpliPhi Wiring Guide for a list of distributors that sell
cables.
Battery cables can be custom ordered to include the 3/8” lugs that fit on the AmpliPHI
Battery’s threaded studs.
Determine the cable length for the AmpliPHI Battery terminal farthest from the common
busbar or plate first.
Additional cabling or slack that remains with the shorter distance runs can be coiled
and secured with Zip Ties.
Wire length should be kept as short as practical.
Positive wire runs should be separated from negative wire runs in separate conduit.
Energy supplied by the AmpliPHI Battery is reduced as electrical current moves through wire.
For lengths of battery cable greater than ~10 feet (3 meters), ensure that the voltage drop is no
greater than 3%.
To take full advantage of the combined AmpliPHI Battery bank’s surge rating, the DC busbars
or plates that the individual AmpliPHI Batteries are wired to should be rated to match the
AmpliPHI Battery bank’s total surge rating.
MidNite Solar produces the MNLB Lithium Battery Combiner
(rated at 250 Amps MAX) and
the MNBCB 1000/50 Battery Combiner (rated at 1,000 Amps MAX)
CAUTION: Do not reverse polarity. Positive battery cables must connect to the AmpliPHI
Battery’s Positive terminal studs and to Positive DC busbars or plates. Negative battery
cables must connect to the AmpliPHI Battery’s Negative terminal studs and to Negative DC
busbars or plates. Reversing polarity will Void the Warranty.
