MENU SYSTEM

BULK CHARGE TRIGGER TIMER (15) MENU HEADING

Set Start Bulk

time00:00

All Models

Range: 00:00 to 23:50

Starts the bulk charge process at the time shown. Setting to 00:00 defeats this function. This setting should be enabled when using the SLT mode so that the batteries are charged once each day. With the GRID USAGE TIMER enabled, the START BULK TIME setting should be set near the beginning of the charging time window for best operation. Since the battery will usually be fully charged when this timer setting is reached, the battery charger will usually reach the ABSORPTION stage of the charging process quickly and will then hold the battery near the SET BULK VOLTS DC setting for the ABSORPTION TIME setting (default time period is 2 hours). This setting does not need to be adjusted if you are using FLT mode with a generator. This setting works with the AC1 HOT IN 1 input only.

The following information is displayed as additional Menu Items.

To disable timer set to 00:00. If grid timer active set bulk time after start charge time. In SLT mode don’t disable this timer. It is daily chg time.

LOW BATTERY TRANSFER (16) MENU HEADING

Set Low Battery

Transfer VDC 11.3

12 VDC models

Range: 05.0 to 16.5

Set Low Battery

Transfer VDC 22.6

24 VDC models

Range: 10.0 to 33.0

Set Low Battery

Transfer VDC 45.2

48 VDC models

Range: 20.0 to 66.0

This is the voltage at which the inverter transfers the loads from the battery to the utility grid. It is used only with the LBX and FLT modes. This setting is not temperature compensated. The transfer will occur only if the battery voltage remains below this setting for 20 seconds. The system returns to powering the AC loads from the battery once the battery voltage has reached the LOW BATTERY CUT IN setting. This setting works with the AC1 HOT IN 1 input only.

Set Low battery

cut in VDC 13.0

12 VDC models

Range: 05.0 to 16.5

Set Low battery

cut in VDC 26.0

24 VDC models

Range: 10.0 to 33.0

Set Low battery

cut in VDC 52.0

48 VDC models

Range: 20.0 to 66.0

This setting controls when the inverter turns back on once it has shut off when the battery reached the LOW BATTERY CUT OUT VDC setting. It is also used to control when the system resumes powering the AC loads from the inverter when LBX mode is being used. In LBX mode, the best performance will often be achieved if this setting is higher than the BULK and FLOAT VOLTS DC setting in order to reduce cycling of the system. The DC charging sources (wind, solar etc.) must then cause the battery voltage to rise above the charger settings before the system resumes inverter mode operation. This setting is not temperature compensated

See menu 9 to enable LBX mode.

Make sure LBX is above LBCO volts.
