Example A: Three PHI 3.8 kWh-51.2V
nominal
batteries must be paired with an inverter rated at 5 kW AC and
92% efficiency to ensure the PHI Battery bank does not over-discharge to power the loads.

Note: Notice that the two different model batteries in the above example (51.2V
nominal
and 25.6V
nominal
) have
the same capacity rating (3.8 kWh) but different MAX Continuous Discharge ratings. In applications where
greater instantaneous power is required of the battery, it is therefore more efficient to use the PHI 3.8
kWh-51.2V
nominal
battery with 1.92 kW of maximum continuous discharge versus the PHI 3.8 kWh-
25.6V
nominal
battery with 1.15 kW of continuous discharge. The same advantages apply when examining the
two different model batteries’ surge capacity.

Refer to the Battery Bank Sizing for Maximum Instantaneous Discharge (Load Rate) tables in Appendix B of
this Manual for a complete list of common battery-based inverters and the minimum quantity of PHI
Batteries those inverters need to be paired with to ensure that the PHI Battery bank does not over-
