CAUTION: If a firmware update is executed on Schneider Electric equipment, ALL the
settings must be reverified. The programmed settings shown in the following tables must be
applied based on desired Warranty/Cycle life. The recommended is 80% depth of discharge.
4.2 – Inverter/Charger Settings
The Conext XW+ Inverter/Charger has a firmware limitation that creates a potential issue with Lithium-Ion
batteries: the Low Battery Cut-Out Voltage (LBCO) setting is limited to 48V maximum. This value is below the
recommended LBCO settings to maximize cycle-life of most Lithium-Ion batteries including PHI batteries. Per
the Warranty, a 48V LBCO corresponds to 100% DoD and maintains a much more limited cycle life.
Until Schneider Electric releases updated firmware to adjust this setting above 48V, this issue can be largely
mitigated by setting the “Recharge Volts” above the desired LBCO thresholds as outlined in Table 1.0 below.
Therefore, systems that do not rely solely on renewable energy (i.e. grid tied systems, AGS systems) will
typically start charging the batteries once the recharge voltage level is reached, preventing further discharge of
the batteries and thus optimizing cycle-life.

Notes:
•
1.
Maximum setting of 48V limited by some inverter firmware is below the recommended setting.
•
2.
Per PHI 3.8 kWh 48V battery – These settings are calculated by multiplying the nominal value per-battery value times
the # of batteries. For other batteries, refer to the Warranty and Specification Sheet for the specific model. Refer to
Charge Controller Bank Sizing under the “Battery Bank Sizing” section.
•
3.
To calculate Max Bulk Current as a percentage, divide the calculated Max Bulk Current in Amps DC by the equipment’s
maximum potential charging current:
