4.6.1 – Increasing Storage Capacity via Parallel Wiring
Storage Capacity and total available Amperage is increased incrementally with the number of units wired in Parallel. For
example, two PHI 3.8 kWh-51.2Vnominal (75Ah) Batteries wired in parallel are rated at a combined 7.6 total kWh, 51.2
Volts DC and 150Ah. Each PHI 3.8 kWh-51.2Vnominal Battery also has a maximum continuous discharge rate of 37.5 Amps
DC and paralleling two of these batteries incrementally increases the maximum continuous charge and discharge rate. The
two paralleled PHI 3.8 kWh-51.2Vnominal batteries have a combined maximum continuous charge and discharge rate of 75
Amps DC (2 × 37.5ADC).
4.6.2 – Parallel Wiring Batteries with Threaded Studs using Battery Cables
PHI Batteries are paralleled by wiring from individual PHI Batteries to DC busbars or plates, which may be located in a DC
combiner box or the inverter’s power panel.

MISE EN GARDE: Toutes les Batteries PHI sont conçues pour performer à des tensions xes et ne peuvent
pas être câblées en série pour augmenter la tension de la batterie. Le câblage des Batteries PHI en série
endommagera les circuits de protection interne de la Batterie PHI et Annulera la Garantie. Les Batteries PHI
sont conçues uniquement pour un câblage en parallèle, cela pour augmenter la capacité de stockage de la
batterie.
CAUTION: All PHI Batteries are designed to serve at xed voltages and cannot be wired in series to increase
the battery bank’s voltage. Wiring the PHI Batteries in series will result in damage to the PHI Battery’s
protective circuitry and will Void the Warranty. PHI batteries are designed for parallel wiring only to increase
the battery bank’s storage capacity.
Although lead acid batteries are typically wired using battery-to-battery interconnecting cables, SimpliPhi asks that PHI
Batteries NOT be wired in this way.
