Inverter Operation

To operate the inverter, turn it on using the ON/OFF switch on the front
panel. The inverter is now ready to deliver AC power to your loads. If
you are operating several loads from the inverter, turn them on
separately, one by one, after the inverter has been turned on. This will
ensure that the inverter does not have to deliver the starting currents for
all the loads at once and give you a problem free performance.
3-6-1. Controls and indicators:
The ON/OFF switch turns the control circuit in the inverter on
and off. It does not disconnect input voltage from the inverter.
The Dometic SI1500 Sine Inverter operates from an input
voltage ranging from:
10.5 to 15.0 VDC for 12V models,
20 to 32Vdc for 24V models
The Dometic SI 1500 Sine Inverter will indicate high and low
DC voltage conditions as follows :

3-6-2. Battery voltage indicator:
The battery voltage bar graph indicates the voltage level at the
input terminals of the inverter. At low input current, this voltage
is very close to the battery voltage. At high input current, this
voltage will be lower than the battery voltage because of the
voltage drop across the cable and connections. Ideally, the
voltage should remain in the green areas of the bar graph. If
the voltage goes into the red area at top and bottom of the
graph, inverter may shutdown.
