Setting Up Your Inverter
Cobra Pro Power Inverters are equipped with
(2) settings to accommodate battery run times
for both large and small vehicles.
From the factory the PRO Power Inverter is set to an
11.5 Volt default Battery Low Voltage Alarm and will automatically shut down
at
10.5 Volts
to protect the battery from deep discharge (so you can start
your vehicle). This setting is ideal for Professional Trucks. If using a
Cobra PRO Power Inverter with a car, van or RV, the Alternative
Setting is recommended since batteries in these vehicles can afford a
slightly deeper drain and will avoid an “early” Battery Low Voltage Alarm
signal and longer run time.
CAUTION: The Default Low Voltage Alarm Setting is designed for
Professional Trucks and larger vehicle batteries.
If using this setting with
a standard vehicle, van or RV, the alarm will sound earlier than
necessary
and reduce battery run time.

Instructions For Changing Low Voltage Alarm Setting
to 10.5 Volts
1. Connect the Remote On/Off Controller with Fast Charge
USB (Optional)
2. Press the POWER button to turn on your inverter (or the POWER
button on the remote controller)
3. Press and hold the POWER button for 5 seconds or until Input Voltage
LED turns blue
4.
Once blue, the Battery Low Voltage Alarm will be set to sound when
your battery Voltage reaches
10.5 Volts
. The power inverter will
automatically shut down when battery voltage reaches
9.5 Volts
to
protect the battery from deep discharge (so you can start your vehicle).
The setting will not change when the inverter is turned off or the
battery is disconnected. To set the inverter back to the Battery Low
Voltage Alarm Default Setting at
11.5 Volts
, follow steps 1 and 2.
CAUTION: Your power inverter will automatically shut off at
9.5 Volts
when
set to the Alternate Battery Low Voltage Alarm Setting. Do not set the
Battery Low Voltage Alarm Setting to the Alternate Setting when
using your inverter with a Professional Truck or larger vehicle.
