Manual alarm clearance

DIS: Manual alarm clearance (disabled by default)

ENA: Enable manual alarm clearance. Ten seconds after you exit the setting screen, the device restores the initial status of manual alarm clearance and cancels alarms.

Maximum charge current

• Default value: 10 A
• Value range: 10–30 A. The value increases by 10 A each time you press SELECT.

Output voltage

You need to shut down the inverter before changing the output voltage.

220: indicates that the output voltage is 220 V AC.

230: indicates that the output voltage is 230 V AC (default value).

240: indicates that the output voltage is 240 V AC.

Set the number of parallel UPSs

• Default value: 1
• Value range: 1–2

Battery discharge time

• Default value: 0H (this function is disabled)
• Value range: 0H–48H

Battery capacity

• Default value: 100 Ah; value range: 50–2400 Ah. The value increases by 50 Ah each time you press SELECT.
• Battery string sharing enabled: When setting the battery capacity, set the total battery string capacity for each UPS.
• Battery string sharing disabled: When setting the battery capacity, set the capacity of the battery string connected to each UPS.

Output frequency

You need to shut down the inverter before changing the output frequency.

• 50 Hz (default)
• 60 Hz

ECO mode

DIS: Disable ECO mode (default). When the mains is available, the UPS works in normal mode. If the mains frequency is unstable, the UPS works in battery mode.

ENA: When the mains is available, the UPS works in ECO mode.

Shallow discharge test

DIS: Disable shallow discharge test (default).

ENA: Enable shallow discharge test. The shallow discharge test time is controlled by the battery discharge time and discharge percentage.

Discharge percentage

• 20% (default)
• Value range: 10–50%. The value increases by 1% each time you press SELECT.

Buzzer off setting

Enable or disable the buzzer off function.

ENA: Enable the buzzer off function.

DIS: Disable the buzzer off function (disabled by default)

Automatically return to the default screen

ENA: Return the default display screen (default). If no button is pressed within 1 minute in any mode, the default screen (input voltage/output voltage) is displayed.

DIS: Stay on the current screen. The display will stay on the screen currently turned on by the user.

Equalized charge voltage

• Default value: 54.0 V
• When the lithium battery does not communicate, the value range is 53.5–57.0 V. The value increases by 0.1 V each time you press SELECT.

  When the lithium battery is communicating, the UPS automatically adapts to the equalized charging voltage based on the connected lithium battery model. The value is fixed and cannot be changed.

Float charge voltage

• Default value: 54.0 V
• When the lithium battery does not communicate, the value range is 51.0–56.0 V. The value increases by 0.1 V each time you press SELECT.
• When the lithium battery is communicating, the UPS automatically adapts to the float charging voltage based on the connected lithium battery model. The value is fixed and cannot be changed.

Battery (EOD) point

• Default value: 44.0 V
• Value range: 44.0–46.0 V. The value increases by 0.1 V each time you press SELECT. The battery EOD threshold is fixed at the current value regardless of the load percentage.

Set the communications address

The default communications address is 001, which is used for the RS485 communications ports (connect to northbound devices). Set different communications addresses for parallel UPSs.

Restore factory settings

DIS: Disable the function of restoring factory settings (default).

ENA: Enable the function of restoring factory settings. The setting takes effect after you exit the setting screen. After factory settings are restored, the output voltage, calibration parameters, and log information are not restored.

LCD password control

ENA: Enable LCD password control (default). After the function is enabled, a password is required for accessing the settings screen.

DIS: Disable LCD password control. After LCD password control is disabled, no password is required for accessing the setting screen. However, other users may have the permission to access the parameter setting screen to modify parameters.

Password setting

• Initial password: 000001
• You are advised to change the initial password after installation.
• On the password login screen, press and hold ON/MUTE, SELECT, and OFF/ENTER at the same time for 3s to restore the initial password.

Altitude-based derating

• Default value: 1000 m When the altitude exceeds 1000 m, the output power is derated by 1% for each additional 100 m. The power can be derated down to 70%.
• Value range: 1000–4000 m

Deep discharge test

DIS: Disable battery deep discharge test (default).

ENA: Enable battery deep discharge test. This function can be enabled only when the battery SOC is 100%.

Battery string sharing

ENA: Enable battery string sharing (default).

DIS: Disable battery string sharing.

Exit the setting mode

ESC: Exit the setting mode.
