Hypertough 750-watt inverter, display-voltmeter problem

Applied battery-voltage will be 12.8 volts, display-voltmeter on the inverter will show 11.5 volts. But if I apply voltage to the inverter using a DC power-supply, the display-voltmeter will be correct.

Most likely the battery volts are displaying correctly. There is a voltage drop on the battery due to its internal resistance, when you connect a supply the voltage drop is less.
If you were to put a new battery on it it might reduce the voltage drop, as long as the battery is designed for the current load it's taking.
If it's working I wouldn't worry, but if the voltage continues to drop with use I'd be thinking it needs a new battery. (Assuming the battery is charging correctly)

Testimonial: "Thanks for the input. I checked battery-voltage with my meter, the inverter-display is definitely off....very little V-drop on the high-current lines."

Aims 2000 watt power inverter will not turn on. i have it hooked in series to two 12 volt batteries and when i flip the on switch nothing happens

try parallel .
negative battery one to negative battery two
positive battery one to positive battery two
all positives to inverter positive
all negatives to inverter negative

Why ?
if batteries are in series you are adding voltages so inverter gets 24 volts when it is rated at 12 v to 16v but two batteries in parallel increases the current available and capacity but keeps voltage at 12 v

Xantrex inverter error codes

This information expands upon the error code information contained in the Link 2000 Owner?s Manual.
E-01 Inverter high DC/Battery voltage shutdown Battery voltage has risen above 15.5 VDC for 12-volt models or 31 VDC for 24-volt models.
E-02 Inverter low DC/Battery voltage shutdown Battery voltage has dropped below 10 VDC for 12-volt units or 20 VDC for 24-volt units.
E-03 Inverter or Charger overtemp shutdown Unit will reset automatically after it has cooled sufficiently.
E-04 Battery overload Caused by excessively discharged batteries. See section in inverter owner?s manual titled ?Charging overdischarged batteries.?
E-05 AC Backfeed AC power from an outside source has been fed to the AC output of the inverter. Potentially damaging to the unit. Disconnect incoming AC power and correct the situation.

De inverter switches off indicating low Batteries while according to my monitor ( xantrex charge ) battery bank is 100%. How can I help help it?

use a voltmeter and measure the voltage AT THE INVERTER'S Battery terminals and see if its over 11 volts. You could have a loose connection or a bad cable creating a voltage loss.

Check gauge light comes on and voltmeter shows low voltage

start the car. if you have a volt meter at the battery you should have 13 to 14 volts while running. if not your alternator isnt working.

Why would my new 1500 watt inverter readout show overload 13.8 volts entering

It would show overload if you're drawing more power than it can supply. 1500 Watts is a very high output for an inverter but that is the maximum it's capable of. As with any electrical supply you should not draw the maximum power it's capable of as this can cause it to burn out. Around 1200 would be the max you should draw continuously. You need to check the power requirements of whatever you're running on it. Also you need to check that it's capable of taking 13.8 volts. If 12 volts is the recommended input, putting in 13.8 will increase the voltage output which could damage appliances being run on it.

My fredom 25 inverter is not running the refrigerator in my motor coach when I turn the generator off or unplug from shore power.

Is the inverter rated for more power than the refrigerator draws (watts). Does the coach 12 volt power drop (at the inverter) below 12 volts when the refrigerator comes on? If so, you may need to increase the wire size from the battery to the inverter. Make sure that the voltage doesn't drop at the battery. If so, it may need replacement or a larger capacity battery. When the battery is being charged, measure the voltage at the terminals (which are hopefully clean)--it should be 13.5 to 14.5 volts.

My aims 2000 pure sine wave inverter is pluged to 2 240amp/h 6 volt batteries. When | plug in a 1800 watt hairdrier i get an alarm as if the batt. were to low. they are new and at full charge. is the load...

Your inverter has a peak of 3000 watts rating and should power that hair dryer. Make sure your batteries are in good shape. The inverter can only put out what it takes in. 1800 watt demand on the inverter requires 1800 watts from the batteries.

97 gixxer 750, will not start. Starts fill with

Your charger should be putting out 13.0-14.5 volts to keep the battery charged. Otherwise its running off the stator sometimes and the battery at other times depleating the battery. The voltage regulator could be bad or the stator could be bad. try swapping the volt regulator first and start from there. Also a battery that has been depleted should be sufficiently recharged before using it again.

Low voltage output from inverter

I am thinking this a high impediance device problem and this is normal operation - the user manual of my inverter warns about use with high impediance devices - if not I am interested also...
