inverter tripping

I have a 3000/6000 pure sine wave power inverter by PowerTechON. I have it wired from 3 aux. batteries in parallel. When I turn the inverter on, it stays on for about 15 seconds then it starts to buzz and keeps alternating between on and tripped, with the red light on. I tested the connections at the inverter and it shows 13.4 amps. Any help would be great!!

I assume you meant 13.4 volts. The first thing I would check would be the polarity on the inverter's input connections.

also make sure the batteries are truly in parallel and not an accidental series connection between a couple of them..

Yes you are correct meant volts. I checked the polarity and it looks correct. Thanks

Danger Will Robinson! Fire, Shock Hazard, Warning! That is a powerful inverter and nothing to trifle with.

I'm no expert but that sounds like a problem with the load side. So, not the batteries but what you have plugged in to the inverter downstream, or a dead short. A serious dead short exceeding fifty amps!

This is a skoolie conversion website so I assume you have some knowledge of your system. If so, shut off every circuit breaker and unplug every appliance to reduce the load on the inverter. If it stops tripping, it is a problem with too much load downstream.

If you don't have much knowledge of your system, BRING IN AN EXPERT. From your description the inverter appears to be supplying over fifty amps downstream. That's either a dead short or something seriously wrong with a major appliance. Fifty amps is how much I use when I set my welder to maximum power.

Any update?....it does sound like a possible overload. Or maybe a short somewhere.

I have checked the polarity on all batteries, all ok. Have disconnected all load from inverter. The inverter stills trips. Put a 2500 watt inverter on and everything works fine.

Good to hear the resolution. So a bad inverter then?

I have a Maytag stick welder. The breaker is fifty amps. Yes the welder goes up higher but only on a duty cycle, so I could probably weld all day long at max, in short bursts.

The point I was making was something is tripping the max/inrush current, just like I would if I ran the welder hot and hard for longer than the duty cycle.

wish you luck on finding parts for it.
it is most likely the rectifier.
assuming a plugged or hard wired machine.
