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 B
ULK VOLTS DC to the same setting on both inverters.
• Set the 12C F
LOAT 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 B
ULK 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 E
QUALIZE VOLTS DC setting.
• Set the 12G EQ V
DC 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.
