I mistakenly connected energy source at the AC inverter output .Inverter is 5KVA cyberpower inverter.After correcting the connection, It cannot switch from DC to AC( fault signal is displayed on its display. But It gives output when put at "bypass" . It also charges the batteries nicely.

The biggest difference between inverter and non-inverter AC is the fact that the motor of the inverter compressor has a variable speed. The speed of the non-invertor compressor is fixed. This means that it operates either at full or minimum speed. A censor in the invertor adjusts the power according to the temperature in the room, lowering the electrical consumption and saving energy.

Due to the sophisticated operational method of the invertor, its compressor does not work at its full capacity all the time. When the speed is lower, the needed energy is lower too and you pay less money for electricity.
As the compressor motor of the inverter air conditioner does not turn on and off all the time, but keeps working at low power, the operation is more quite.
The technology of the inverters not only makes cooling and heating more efficient, but it also makes the AC's life longer.
Last but not least, the inverter AC is able to cool or heat your room faster than the non-inverter. This is due to the fact that in the beginning of the process, the inverter uses more power than the non-inverter and diminish the power when it gets close to the desired temperature.

no statement at all its use;. sure a BOAT, got you there,
how is this inverter connected on both ends.
one end is DC other is AC out. right>?
12vdc input (the big red/black wires) not reversed nor fuse blow, to these pair.
the output is a large AC power jack pure sign wave AC power. it does, means can run computers and things that hate cheap chopper type inverters.

why did you say connected to shore power(AC)
that is not its purpose or job ever. that.
its purpose is to convert, DC battery power to AC POWER
at up to 1200VA (watts)
that is about enough power to run a toaster.(almost)

do not ever connect shore 120VAC power to that large connector on the front of this inverter or you will blow it straight to H3LL
and worse a fire.
the jack there is marked OUTPUT, so connecting short AC output to inverter output is super wrong and dangerous.
I can tell you shore power will win the bucking war here,
boom fuse blows, fire, and smoke can happen., and will. 1 or all 3.

answer 2: connected right (per makers web site see it)?
battery main boat not dead or just disharged. 12.6vdc is good, less bad.
AC jack output on inverter works with say a desk lamp 120VAC 100watts , if not the inverter fuses blow or bad inverter.
some you can hear it sing, ear to casing. (inverter oscillator inside)

is not possibily,to any ac.the timer run just for 24 hours.on the power surce of your ac you can make a timer control programms, who take or give energy to your ac inverter(you put the ac inverter to run , and when the energy is shut down ,the ac inverter is stop working and when the energy is come back the inverter start working)

Checking AC Output
1. After the battery voltage and connections have been checked, disconnect the inverter.s AC output wires from
the power distribution system and connect a light to the AC output of the inverter/charger.
2. Disconnect the remote panel to eliminate it as a possible problem.
3. Turn the inverter ON using the power switch on the front panel of the inverter. The 100-watt light should
illuminate. Measure the voltage at the AC output wires using the multimeter. The reading should be 114.126
VAC or approximately 230 VAC if the unit is an international model. If the light does not illuminate, there is
a problem with the inverter. Contact Xantrex technical support.

Hi Schnupfy,

Well, it may be advertised as 1800 watts, but that is a peak. While the 230 VAC may be dead on target, don't expect it to run a mig welder.

Sustained high output is totally dependent upon the power source. What it's doing is protecting itself. DCDC Shutdown indicated 'An overload or system Fault'

Possible problems that would cause this:

• The load is too high (what is the load?)
  
• The power source is intermittent or weak
• The power source is run through a distribution panel or isolator (Voltage drop)
  
• The wiring from the 12VDC source is too long for the gauge used

Inverters normaly have inbuilt protection built into them check for reset button/switch.

If you are referring to a Trace 2412 inverter, which series is it? An SW or a DR series? In either case, if it won't accept generator power, but the AC input indicator is flashing, the problem is most likely the generator output power is off frequency or voltage. Trace inverters will only connect when the AC input is within certain limits. I'd suggest checking the frequency and voltage output of the generator. If it won't connect to shore power, check the voltage from that source. Make the voltage checks at the inverter input terminals.

Inverters works from 12v carr battery or backup battery, you can not charge the inverter you msay killed your inverter if you connected to 120v wall mount...you use the inverter to give you AC (electric) from 12v battery. if your tv is 12v you need to know how much needed to get the correct connrection as output and input.
