LBX (Low Battery Transfer) Mode Settings in Xantrex SW4024 Inverter
Can anyone explain the follow passage from page 46 in the Xantrex SW manual regarding correct settings for LBX mode?
Are they referring to the BULK and FLOAT volts settings in the Inverter, the charge controller, or both? In a 24 volt system, would this mean that you need to set the LOW BATTERY CUT IN voltage somewhere around 30 volts (FLA batteries) to put it above the bulk voltage setting? Will the batteries ever get that high in order to disable the LBX function and return the inverter to service?SET LOW BATTERY CUT IN VDC - This setting controls when the inverter turns back on once it has shut off after 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.
