Xantrex Technology 120 VAC/60 To start the equalization process either manually or automatically

OPERATION

The battery manufacturer or supplier should be consulted before equalizing to provide the recommended process and settings. During the equalization process, check the temperature of each battery every hour by momentarily feeling the battery case. If the batteries are excessively warm (too hot to keep your hand on), terminate the charging immediately. Let the batteries cool before checking the need for further equalization charging.

A manual or automatically controlled equalization charge process is available in the SW Series Inverter/Charger. This equalization process can be powered by any AC source. The SET EQUALIZE TIME H: M menu item under the BATTERY CHARGING (10) menu heading sets the amount of time that the battery voltage must exceed the SET BULK VOLTS DC setting before the equalization process is completed. This timer is an accumulating type and does not reset if the voltage momentarily drops below the bulk voltage setting. During the equalization process, the voltage is limited to the level of the SET EQUALIZE VOLTS DC menu item under the BATTERY CHARGING (10) menu heading.

To start the equalization process (either manually or automatically):

Select EQ from the SET GENERATOR menu item, by pressing the green GEN MENU button on the Control Panel. During the equalization process, the BULK LED will flash slowly to indicate that the EQ position has been selected from the SET GENERATOR menu item.

To manually equalize the batteries, AC power must be available at the AC HOT IN 1 (utility power) or AC HOT IN 2 (generator) terminals. If utility power is not available, the generator must be manually started. The inverter uses this power to start the battery charger and begin the equalization process. Equalization will continue to run for the amount of time programmed. When the equalization process finishes, the FLOAT LED will come on (as long as utility or generator power is still available).

NOTE: If the generator was manually started to equalize the batteries, it must be manually shut off once equalization has completed. Return the cursor to the OFF position in the SET GENERATOR menu item (accessible by pressing the green GEN MENU button on the Control Panel).

If the automatic generator control system is selected, the inverter will complete an equalization charge process during the next - automatically started - generator run period.
