LCD Contrast:
This changes the display screen contrast. Six settings are available. Lighter
contrast settings may leave the screen difficult to see in a bright atmosphere.
External Shunt:
The inverter monitors both AC and DC current values, whether charging or
discharging (figures are approximate), by using internal or external shunts. A
shunt monitors partial current consumption, allowing the majority of current to
pass on heavier conductors. Programming shunt selection affects which shunt
the inverter is using to monitor DC current values. Single inverter systems use
their internal shunt to monitor system DC current values. When programming
single inverter systems select External Shunt None. Dual inverter systems use
an external shunt to monitor system current values. When programming the
shunt selection of a dual inverter system, the master inverter is programmed by
the remote installed in the monitor panel. The master inverter will be programmed
as External Shunt This Inverter. The slave inverter will be programmed as
External Shunt Other Inverter.
Fuel Gauge Cutout:
Battery chemistries and types have different static voltage readings at dif-
ferent states of charge. The battery voltage may be used to determine an
approximate state of charge for that battery type and chemistry. The Fuel
Gauge Cutout voltage is a reference point the inverter uses to determine a
battery with no reserve capacity amp hours remaining. Changing the value of
the Fuel Gauge Cutout will affect the fuel meter, automatic generator start and
stop points if set by SOC (state of charge) and time left to run or charge. The
Fuel Gauge will read 0 when the Fuel Gauge Cutout pre-programmed voltage
reaches 50% SOC.
NOTE: The remaining field items are used to program the
Automatic Generator Start parameters.
The house batteries operate most of the interior lighting and most appliances.
As the house battery power is consumed the reserve battery capacity diminishes.
The inverter can be programmed to automatically start and stop the generator
to keep up with the drain on the house batteries. All field reference points are
house battery indications or conditions. A wide field of parameters may be
chosen for the generator start and stop points. These points may be set in three
categories:
1. House battery voltage.
2. State of charge (SOC). The Fuel Gauge Cut-out affects SOC.
3. Absorb or Float point of the charge cycle.
