3000 watt eliminator with OLP and LUP CODES any Ideas

Assuming you have a 12VDC In 120V AC out 3000W inverter.
LUP indicates battery voltage is low, so firstly make sure:

1. You 12V battery is good, it's large enough a minimum of 75AH and probably much larger is recommended and it's fully charged.
2. Verify you are using the correct size copper wires from battery to the Inverter DC INPUT(s). If you keep wire short the wire size can be smaller, but if the DC input wires are longer then you will need to use thicker copper wires.

At MAx load you would be taking 250 AMP from battery, so for a 5% Volatge drop of .6 V for a 10 ft length of cables from battery to Inverter you would need to use a 1AWG copper cable.

OLP is a overload condition, which means you may have to many high powered AC powered things connected to the Inverters AC outlets or maybe something that has large start up surge, ie devices large electric motors.

Or it could be all due to a faulty Inverter.

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.

How do I remove electrical interference on my dvd recorder?

Hi David
You need to figure out how the interference is getting inside.
Look at the external connections.
HDMI Cable or Perhaps the Power Connector.
Noise from the power cable would be most likely.
A Ferrite Bead can often be clipped onto power lead to dampen electrical noise. Electronics supply stores have these.
If an AC to DC external box is used. What is the required DC input to your DVD ?
For example if the AC is dropped to 12v DC and then plugged into player via a small connector. You could get your own connector and supply from a 12v vehicle battery. Be careful to maintain correct polarity to tip of connector.
Use a cheap multimeter to check voltage & polarity.
Substitution....This would prove that the noise source is from the Power Supply.

Alpine 345 amp flashes VLT

If the fault occurs even with the engine switched off , there is no reason of excess voltage but if the inverter DC-DC convertor within is faulty it can cause this error.
You can remove the covers and check for any visible signs of capacitor leak or burning. Unless the circuits are isolated the fault cannot be traced or confirmed. It can be a short in any of the regulators or drivers but has to be confirmed.

No power to refrigerator unless it is hooked up direct. Think it is 12 volt dc supply connection. Could this be the problem only able to get partial # on part c1c 5122 is all we can read.

there is an inverter built in to the power supply that converts dc to ac to run the compressor if the fuse is ok. you will have to replace the supply . or for traveling you could hook up a small inverter to opperate the fridge while traveling this could be connected to the 12 vlt line for fridge power as it will not take much more power than the the fridge needs.

175 watt 350 peak inverter 12v dc to 110 ac need a fuse but don't know what size to use. old fuse is missing.

15/16 amp would be recommended.
You could to try a 20 amp, but you will risk overheating and the possible failure of the vehicle circuit fuse.

Q7 12V socket Inverter Wattage Question

no you need to know the wattage of the item you are trying to power. To find the wattage of the item you are trying to power is simple. Some will say directly others will give you the amps (ie. .5amps, 1.2 amps.) you take the amps and multiply it by the volts that it says. All this info is on the item you are trying to power with the inverter. The answer is what it will take to power that item. example .5amps x 240v = 120 w so in this instance you would need an inverter that would produce at least 120w so in this case the 150w inverter would work. Good Luck, have a grt day

you should connect it to the 12v positive of the power supply, maybe install a switch in line between the amp and power supply.
