|---|---|
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 lesser of the inverter’s max charge capacity, or the quantity of attached batteries, multiplied by the battery model’s specific max charge rating. For example, a 12K-P inverter would be set to the lessor of the inverter’s max charge rate of 185 A, or 190 A for two AES RACKMOUNT 48-48-5120 batteries rated at 95 A max charge each.(1) For a three-phase system: set to the lessor of the max charge value for the master inverter, or the quantity of attached batteries, multiplied by the battery model’s max charge rating, divided by the number of inverters. For example, the master 12K-P would be set to the lessor of the inverter’s max charge rate of 185 A, or 126 A, for four AES RACKMOUNT 48-48-5120 batteries rated at 95 A max charge each (380 A divided by three inverters). |
Max A Discharge | For a single inverter: set to the lesser of the inverter’s max discharge capacity, or the quantity of attached batteries, multiplied by the battery model’s specific max discharge rating. For example, a 12K-P inverter would be set to the lessor of the inverter’s max discharge rate of 185 A, or 190 A for two AES RACKMOUNT 48-48-5120 batteries rated at 95 A max charge each.(1) For a three-phase system: set to the lessor of the max discharge value for the master inverter, or the quantity of attached batteries multiplied by the battery model’s max discharge rating, divided by the number of inverters. For example, the master 12K-P would be set to the lessor of the inverter’s max discharge rate of 185 A, or 126 A, for a battery bank of four AES RACKMOUNT 48-48-5120 batteries rated at 95 A max discharge each (380 A divided by three inverters). |
TEMPCO | Set to 0 mv/C/Cell. (2) |
Use Batt V Charged | Enable |
Use Batt % Charged | Disable |
No Battery | Disable |
BMS Lithium Batt | Disable (Displays 00 value) (3) |
Activate Battery | Enable |
(1) The recommended value for Max A Charge is 75% of the rated maximum charge current for the battery. (2) Discover Lithium batteries do not require temperature compensation. Setting TEMPCP to O mv/C/Cell will disable inverter-charger controlled temperature compensation. (3) Setting the BMS Lithium Batt parameter to Disable confirms open-loop operation. Setting the parameter to Enable confirms closed-loop operation. The values and parameters used are for an assumed operating temperature of 25 °C (77 °F). | |
