CAUTION: When PHI battery quantities change, the capacity & charge/discharge current settings
must be reassessed. Failure to do so will void the Warranty.

Notes:
• 1. Per PHI 3.8 kWh battery – These settings are calculated by multiplying the nominal per battery value
times the # of batteries. Refer to Charge Controller Bank Sizing under the “Battery Bank Sizing” section.
• Levels are typical @ 25C and may need adjusting at temperature extremes.
• When performing rapid deep charge/discharge cycles the battery should be allowed to "rest" 15 minutes in
between.
CAUTION: When PHI battery quantities change, the capacity & charge/discharge current settings
must be reassessed. Failure to do so will void the Warranty.
While the FLEXnet DC Battery Monitor provides State of Charge (SoC) readings, the PHI batteries’ most
accurate SoC gauge is according to Voltage:
