Battery Setting - Self-Managed (Open-Loop) Charge Settings

All values and parameters assume an operating temperature of 25 °C (77 °F).

Touch the Up and Down arrows to scroll through screens. Touch the check mark button to save changes, X to cancel. Ignore data displayed in gray boxes.

Battery Setting (page 1)

Batt Mode

Lithium (1)

Use Batt V

Use Batt %

No Battery

Select the Use Batt V option to use battery voltage for all the settings.

Activate Battery

Select this check box.

Batt Capacity

Set to the number of Discover Lithium batteries x Ah capacity of each. For example, set to 200 Ah (2 x 100 Ah) for two AES RACKMOUNT 48-48-5120 batteries.

Max A Charge

For a single inverter, set to the smaller value between the inverter’s maximum charge rate or the quantity of attached batteries multiplied by the battery’s maximum charge rating.

For example:

Single phase system with Ex9N-DH-6KS-AU inverter and two AES RACKMOUNT 48-48-5120 batteries:

  • Set the Ex9N-DH-6KS-AU inverter to the lesser of the inverter’s maximum charge rate of 135 A, or 190 A for two AES RACKMOUNT 48-48-5120 batteries that are each rated at a maximum charge rating of 95 A (2 x 95 A = 190 A).

Three-phase system with three Ex9N-DH-6KT-AU inverters and four AES RACKMOUNT 48-48-5120 batteries:

  • For a three-phase system, set to the smaller value between the master inverter’s maximum charge rate or the quantity of attached batteries multiplied by the battery's maximum charge rating divided by the number of inverters. For example, set the Ex9N-DH-6KT-AU inverter to the lesser of the inverter’s maximum charge rate of 150 A, or 126 A for four AES RACKMOUNT 48-48-5120 batteries that are each rated at a maximum charge rate of 95 A, and then divided by three inverters (4 x 95 A ÷ 3 = 126.667 A).

Max A Discharge

For a single inverter, set to the smaller value between the inverter’s maximum discharge rate or the quantity of attached batteries multiplied by the battery’s maximum discharge rating. For example, set the Ex9N-DH-6KS-AU inverter to the lesser of the inverter’s maximum discharge rate of 135 A, or 190 A for two AES RACKMOUNT 48-48-5120 batteries that are each rated at a maximum discharge rating of 95 A.

For a three-phase system, set to the smaller value between the master inverter’s maximum discharge rate or the quantity of attached batteries multiplied by the battery’s maximum discharge rating divided by the number of inverters. For example, set the Ex9N-DH-6KT-AU inverter to the lesser of the inverter’s maximum discharge rate of 150 A, or 126 A for four AES RACKMOUNT 48-48-5120 batteries that are each rated at a maximum discharge rate of 95 A and then divided by 3 inverters (4 x 95 A ÷ 3 = 126.667 A).

(1) To configure the self-managed (open-loop) parameters, do not select the Lithium parameter. Selecting the Lithium parameter enables the BMS for managed (closed-loop) communication.

Battery Setting - Generator / Grid Charge Settings

Touch the Up and Down arrows to scroll through screens. Touch the check mark button to save changes, X to cancel. Ignore data displayed in gray boxes.

Battery Setting (page 2)

Start (%)

Not required in a self-managed (open-loop) configuration.

Activate Battery

Set to the same Amp value that was used for the maximum charge current. (1)

Gen Charge

Select this check box if charging the battery bank from an attached generator. (2)
Note: The Gen Input Breaker must be connected to the output of an AC generator for this work.

Gen Signal

Normally open relay that closes when the Gen Start signal state is active.

Gen Force

When the generator is connected, you can force the generator to start without meeting other conditions.

Grid Change

Select this check box if charging from the grid is desired. (3)
A Grid Input Breaker must be connected to input from the grid for this to work.

Grid Signal

Clear the check box.

(1) If need be, this value is used to curtail the maximum current output of the charger.

(2) The options in the left column are for Generator Charge AutoStart values. Refer to Noark documentation for information on using the Generator AutoStart function.

(3) The options in the right column are for Grid Charge values.

Inverter outputs a warning when the battery reaches the specified SOC.

Restart (%)

Inverter AC output continues when the battery reaches the specified SOC.

TEMPCO (mv/C/Cell)

Set to 0 mv/C/Cell. (1)

Batt Resistance

Keep the default value of 25 mOhms.

(1) Discover Lithium batteries do not require temperature compensation. Setting TEMPCO to 0 mv/C/Cell disables inverter controlled temperature compensation.
