Helpful Tips:
• SimpliPhi’s complete wiring guide can be found at this link: https://simpliphipower.com/wp-content/uploads/
documentation/phi-series/simpliphi-power-phi-series-batteries-threaded-terminal-wiring-guide.pdf
• Power cabling for paralleling PHI 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, efciency and overall quality.
• Each PHI Battery’s individual wire runs are typically sized at 4 AWG, according to the 80A built-in breaker.
• Conductor ampacity can be determined using National Electrical Code tables.
• Depending on the electrical code of the local Authority Having Jurisdiction, the PHI Battery leads’ gauge may need to be
sized according to the built-in breaker or according to the PHI Battery’s surge rating.
• Battery cables can be custom ordered to include the 3/8” lugs that t on the PHI Battery’s threaded studs.
• Determine the cable length for the PHI Battery terminal farthest from the common busbar or plate rst.
• 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 PHI 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 PHI Battery bank’s surge rating, the DC busbars or plates that the individual PHI
Batteries are wired to should be rated to match the PHI 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)
MISE EN GARDE: Ne pas inverser la polarité. Les câbles positifs de la batterie doivent être raccordés aux
bornes Positives de la Batterie PHI et au jeu de barres ou plaques CC Positives. Les câbles de la batterie
Négative doivent être raccordés aux bornes Négatives de la Batterie PHI et au jeu de barres ou plaques CC
Négatives. Inverser la polarité Annulera la Garantie.
CAUTION: Do not reverse polarity. Positive battery cables must connect to the PHI Battery’s Positive
terminal studs and to Positive DC busbars or plates. Negative battery cables must connect to the PHI
Battery’s Negative terminal studs and to Negative DC busbars or plates. Reversing polarity will Void the
Warranty.
