My new 1575 3000w invertor shows a OLP error. it will NOT clear. Is it junk?

Not necessarily, remove all items connected. Let the unit cool. Then reconnect 1 at a time.

I found out the cobras are not great inverters. It wouldn't even run my 900 W microwave. So the answer to your question is yes they are junk. Get your money back if you can.

Yes, it is junk. The first one I got worked for 1 day the fan never came on and it ended up only producing 77 volts, Cobra replaced it, the new one works, but, the fan is extremely loud and it only puts out 100 volts, it barely runs my 4.5 cu' refrigerator/freezer, I am sure it would never run a micro-wave or coffee maker.

I have only installed to 500 watts or more. Probably not enough power from PSU!

I have not found anything. Just assume it's a 5V input, and output is inverted (High input = relay OFF)

You need a new PSU, the one you have is garbage. Not all PSUs are made the same, and all the efficiency certifications are garbage and mean nothing. PSU manufacturers submit "golden samples" for certification, and there is no follow by 80Plus to make sure that the production ones are even close to the wattage or efficiency that they claim on the box. Corsair PSUs always exceed the box numbers and ratings, and there are a few other good ones. Find one you want from here: http://www.jonnyguru.com/index.php

If you ran 4 panels rated at 43 volts each in series (positive of one into negative of the next all the way thru) you would be putting over 160V into it. (43x4=172) It is rated for up to 60V input. Hopefully Chris C is right and there is a fuse. Otherwise yes, you fried it.

Hi Joseph, my Lepa 1600W PSU failed on me after a few days of operation but, thank God, no components were damaged. I've read good things about this PSU so my problem was the exception rather than the rule. Just a WAG on my part but I imagine your experience will be better than mine; in any case, the most important thing to me is it didn't take out anything else when it failed.

The input is 22-60vdc you will work close to The low limit if tour panel generate les than this voltage your invertir will be off, muy suggestión is add another panel to increase The input. Good luck.

It's possible they'll help, and they're certainly the cheapest possible fix, but it's unlikely they'll completely take care of the problem. The RF is probably mostly switching noise from the inverter - I'd look at putting an isolation transformer near the AC output of the inverter and shielding the inverter itself as much as you can.

Mine showed up dead right out of the box. Plugged it in and turned it on with nothing connected but a voltmeter. The light lit up on the switch, but it had no output. I didn't want to open it up and tamper with it , so I just returned it and bought a better power supply. Read more reviews and you will see that others have complained about this supply burning out in short order at moderate loads.

I can't even get mine to produce. The original inverter drained the batteries. What kind of inverter are you using?

Look at the power supply, it should have a voltage shown on the label, then use a Volt Ohm Meter (VOM) to check the voltage. If it reads at or slightly higher than the rated voltage then it is probably OK and the problem is in the amplifier. It could be either unit causing the problem. If it is still in warranty you might be better off to get an RMA from the manufacturer and return it for repair or exchange.

No, i never try. I always have a load on it, and if I turn things off it goes to a standby or power save mode automatically.My inverter have been running for more then 2 years now. With no problems so for.

Bad circuit board, or controller. I have a new circuit board I could sell you. Sounds like a bad controller.

I Would contact Iomga. If that did not work out do an Internet search for a power supply with the right specs Has worked oncefor but has also been a dead end.

If this is a new install, then I'd check that the input voltage setting matches the power being supplied to the motor.
1588499
Nope... sounds like it is defective. The power requirements are the same as a 100W incadescent (even less than actually). Just contact Amazon (or the seller) and let them know and they should send you a new one (and pay for shipping the old one back).

I'm sorry. Being quite familiar with inverters in general and this one in particular, I don't know what that could possibly mean nor does my manual on it reveal what it means.
