4.4 – FLEXnet DC Settings
While the FLEXnet DC (FNDC) provides data logging of shunt information, it does not provide reliable State of
Charge (SoC) measurements of the PHI Batteries when successive partial charging takes place at variable charge
and discharge rates over many cycles. For this reason, using an FNDC in conjunction with PHI Batteries can
frequently be misleading. SimpliPhi certainly recommends against using the FNDC with PHI Battery banks rated
at an Amp-hour (Ah) value less than 100Ah (the lowest programmable value in the FNDC).

Notes:
1. Per PHI Battery – These settings are calculated by multiplying the per-battery Ah value times the # of batteries. Refer to Table
4.0 – Capacity Ratings per Battery (Ah). Note that
100Ah is the minimum programmable value.
2. This setting is calculated by either (A) multiplying the per-battery Amp-hour (Ah) value times the # of batteries, then
multiplying by 0.02, or (B) multiplying the per-battery 2%-capacity value times the # of batteries. Refer to Table 4.0 – 2% of
Capacity Rating per Battery for all PHI Battery models’ per-battery 2%-capacity value.
To avoid conflict between the Return Amps parameter programmed in the FNDC and the Absorb End Amps parameter in any
connected OutBack charge controller, disable the charge controller’s Absorb End Amps parameter by setting it to
0 when a
FNDC is included in the OutBack system.
• Levels are typical @ 25°C 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 and charge/discharge current
settings must be reassessed. Failure to do so will Void the Warranty.
Instead of using the FNDC for SoC readings, the PHI Batteries’ most accurate SoC gauge is according to voltage:
