The fan does not run
This is normal.Ā 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.Ā The voltage in your home is called a āsine waveā, while the voltage from the inverter is a āmodified sine waveā.Ā Because of this difference, you will need aĀ meter that measures ātrue RMSā voltage.Ā If your meter does not measure ātrue RMSā, then it will read low.
If it does not say ātrue RMSā on the front of your meter, then it isĀ notĀ 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.Ā With normal utility power, the neutral and ground are connected together in your fuse box.Ā Outlet testers are designed under this assumption.
The outlet on your power inverter, however, is not configured exactly the same as in your home.Ā 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.Ā 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.Ā 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.Ā If you get the alarm even with the alternator running, then check all the cable connections.Ā 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.
