Operation

Setting Changes

When operating a Sine Wave Plus in a series-stacked configuration, the following settings must be changed for proper operation.

See the Owner’s Manual for the Sine Wave Plus for detailed instructions on accessing and changing the settings using the Inverter Control Module (ICM) on the inverter.

Automatic and Manual Generator Control

When multiple inverters are used with a generator, the inverter connected to the generator via the Generator Start Module (GSM) is designated as the “generator controlling” inverter. The most efficient battery charging is achieved by setting the charging parameters of each inverter slightly differently.

Bulk and Float Charging Parameters

Change the Bulk and Float Charging settings as follows:

•Set the 12B BULK VOLTS DC to the same setting on both inverters.

•Set the 12C FLOAT VOLTS DC to the same setting on both inverters.

•On the non-generator-controlling inverter (the inverter not connected to a GSM), set the charging time for a shorter period than on the generator controlling inverter. This is accomplished by setting the 12F BULK DONE AMPS to a higher setting. If the 12F BULK DONE AMPS is set to zero (0), then the 12H MAX BULK/EQ Timer h:m should be set to a shorter time period on the non-generator-controlling inverter.

Equalize Charging

Change the Equalize Charging settings as follows:

•Set both inverters to the same 12D EQUALIZE VOLTS DC setting.

•Set the 12G EQ VDC DONE TIMER H:M on the “generator controlling” inverter to a shorter equalize time.

To start an Equalize charge (manually or automatically), set both inverters to EQ by scrolling to 01B EQ CHARGE ON/OFF and selecting ON.

During the equalize charge, the Bulk LED will slowly flash on each inverter, indicating the EQ selection has been enabled.
