5.0 – Programming

5.1 – Depth of Discharge

The AccESS comes pre-programmed for 80% depth of discharge (DoD), assuming the AccESS is

connected to an AC power source such as the grid or a generator. This qualifies for the 10-year / 10,000

cycle Warranty on the PHI 3.8 Batteries.

To change the DoD to the 5,000 cycle Warranty or 3,500 cycle Warranty, modify the voltages in the Basic

Settings and Advanced Settings per the Programming section. Refer to the PHI 3.8 Battery Warranty.

If a firmware update is executed on the AccESS, please verify all PHI custom settings are still in place.

These settings can be found at the end of this manual in Section 7.0: Operating Parameters.

5.2 – Configuring the Schneider Electric Conext XW+

The Schneider Electric Conext XW Pro or XW+ is capable of many different modes of operation via

configurable settings. This includes:

• AC Input Settings

• Grid Support Settings

• Prioritizing and Managing Energy Sources

• Generator Support Settings

• Auxiliary Output Settings

These settings can be modified to support the function the owner would like to achieve with the AccESS

unit. To configure the AccESS, please refer to Schneider Electric’s Conext XW Pro or XW+

Inverter/Charger Owner’s Guide.

The Schneider Electric Owner’s Guide contains information and procedures necessary for configuring,

operating, maintaining, and troubleshooting the Schneider Electric Conext XW Pro or XW+

Inverter/Charger. The guide is intended for anyone who needs to operate, configure, and troubleshoot the

inverter. Certain configuration tasks should only be performed by qualified personnel.

5.3 – Operating Parameters Per Warranty

Although the PHI 3.8 Batteries within the AccESS unit are capable of performing at very high rates and

depths of discharge within a very wide temperature range, in order to achieve extended life cycles and to

comply with the Warranty, the operating parameters, indicated in Tables 3.0 and 4.0 below, must be

adhered to. The parameters shown in Table 3.0 below must be applied based on desired Warranty/cycle

life. The AccESS comes pre-programmed for 80% depth of discharge.

5.3.1 – Inverter Programming Settings

Schneider Electric Conext XW Pro or XW+ Inverter/Charger

The Schneider Electric Conext XW Pro or 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 3.8 Batteries. Per the Warranty, a

48V LBCO corresponds to 100% DoD and maintains a much more limited cycle life.

Until Schneider releases updated firmware to adjust this setting above 48V in the Conext XW Pro,

this issue can be largely mitigated by setting the “Recharge Volts” above the desired LBCO

thresholds as outlined Table 1.0 above. Therefore, systems that do not rely solely on renewable

energy (i.e. grid tied systems, AGS systems) will typically start charging the PHI 3.8 Batteries

once the recharge voltage level is reached, preventing further discharge of the PHI 3.8 Batteries
