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 3.5 kWh 48V battery – These settings are calculated by multiplying the nominal value per each battery 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.
• Levels are typical @ 25⁰C 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.
• Always refer to the SimpliPhi Power Manual and Warranty for the specific PHI battery model.
CAUTION: When PHI battery quantities change, the capacity & charge/discharge current settings
must to be reassessed. Failure to do so will void the Warranty.
