Lithium Battery Communication and Setting:

Connecting the BMS communication cable allows the inverter to:

• Torneu a configurar el volum de càrregatage, charging current, and battery discharge cut-off voltage according to Lithium battery parameters.
• Start or stop charging based on the Lithium battery status.

For PYLON US2000 Lithium Battery:

1. Configuració de l'interruptor DIP: Set Dip 1 to "ON" for a baud rate of 9600. Dips 2, 3, and 4 are reserved for battery group address.
2. Procés d'instal·lació:

   b. Switch on the Lithium battery.
   c. Press and hold for more than three seconds to start the Lithium battery.
   d. Turn on the inverter.
   e. Select battery type "Li2" in LCD program 5. The battery icon will light up on the LCD display if communication is successful.

For Lithium Battery without Communication:

To avoid BMS protection without communication, follow these settings:

1. Set battery type as "LIB" in program 01 of F2.
2. Set CV voltage com Volum de càrrega màximatage of BMS-0.5V in program 03 of F2.
3. Estableix el volum de càrrega flotanttage com CV voltage in program 03 of F2.
4. Estableix el volum de tall de CC baixtage ≥ discharging protection voltage of BMS + 3V.
5. Set Max charging current in program 09 of F2 (must be less than the Max charging current of BMS).
6. Set voltage point back to utility source when selecting "SBU priority" in program 05 of F2. The value must be ≥ Low DC cut-off voltage + 2V, otherwise the inverter will show a battery voltage low warning.

Remark: It is recommended to finish settings without turning on the inverter (only LCD display, no output). Restart the inverter after finishing all settings.

5. Manteniment

5.1. Battery Equalization

Battery equalization reverses negative chemical effects like stratification and removes sulfate crystals, which can reduce battery capacity. It is recommended to equalize batteries periodically.

Com aplicar la funció d'equalització:

1. Enable battery equalization in LCD setting program 17 of F2.
2. Apply by either: setting equalization interval in program 21 of F2, or activating equalization immediately in program 22 of F2.

Quan s'ha d'igualar:

A la carrossa stage, when the set equalization interval is reached or equalization is activated immediately, the controller will enter the Equalize stage.

Igualar el temps de càrrega i el temps d'espera:

A l'Equalize stage, the controller charges the battery until it reaches the equalization voltage. It then maintains this voltage. If the battery does not reach the equalization voltage within the set timeout, the charge controller will extend the time. If the battery voltage is still low after the extended timeout, the charge controller will stop equalization and return to the float stage.
