POWER WHERE & WHEN YOU NEED IT
Cobra's family of power solutions are the safe, reliable way to provide you with power, wherever and whenever you need it. With advanced technology and built-in safety protection, you can always count on Cobra for your power needs.
WHAT'S IN THE BOX
Included with your PRO 2500W power inverter are four 48" #4 AWG power cables and terminal protector boots.
Item # CPI2500W
Weight: 5.73 lbs (2599.1 g)
Depth: 11.50 in. (292.1mm)
Width: 8.94 in. (227.1 mm)
Height: 3.74 in. (95 mm)
The fan does not run
This is normal. The fan will only run when needed, if the inverter starts to get hot.
The output voltage is low
The voltage from your inverter is a little different than the voltage in your home. The voltage in your home is called a “sine wave”, while the voltage from the inverter is a “modified sine wave”. Because of this difference, you will need a meter that measures “true RMS” voltage. If your meter does not measure “true RMS”, then it will read low.
If it does not say “true RMS” on the front of your meter, then it is not a true RMS meter and it will read low.
My outlet tester shows an open ground
Outlet testers are intended for testing normal utility power in your home. With normal utility power, the neutral and ground are connected together in your fuse box. Outlet testers are designed under this assumption.
The outlet on your power inverter, however, is not configured exactly the same as in your home. It is normal for an outlet tester to show an open ground. This does not indicate a problem with your inverter.
Does it matter where I mount my inverter?
Your power inverter is not weatherproof, so it needs to be installed where it will be protected from heat and moisture. Keep a minimum 1 inch clearance around the inverter for ventilation.
The inverter can be mounted in any position -- horizontal, vertical, or upside-down.
My inverter makes a squealing sound (alarm sound)
If the battery voltage gets too low, your inverter will sound a low-voltage alarm. This can happen for any of the following reasons:
-The battery is low and needs to be charged
-A loose connection with the battery cables
-A loose connection in the cigarette socket (if you are using a cigarette power cord)
-The battery cables to the inverter are too small
-The appliance is pulling excessive power from the battery
If you get low voltage alarm then try running the engine so that the alternator is supplying extra power. If you get the alarm even with the alternator running, then check all the cable connections. There might be a loose connection somewhere.
How much power can I draw from each AC outlet?
If your inverter has more than one AC outlet, the full inverter power is available from any of the outlets.
