Deye Open-loop Configuration

If using multiple inverter-chargers, configure Deye inverter-chargers to operate in parallel before setting the parameters for battery operation.

Batt Mode

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 SUN-6K-SG01LP1-US inverter and two AES RACKMOUNT 48-48-5120 batteries:

• Set the SUN-6K-SG01LP1-US 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 SUN-6K-SG04LP3 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 SUN-6K-SG04LP3 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 SUN-6K-SG01LP1-US 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 SUN-6K-SG04LP3 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).

Start (%)

Not required in an open-loop configuration.

A

Set to the same Amp value as the maximum charge current. ⁽¹⁾

Gen Charge

Select this check box if charging the battery bank from an attached generator. ⁽²⁾

A Gen Input Breaker must be connected to the output of an AC generator for this to 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.
