Inverter Showing “AC Abnormal”

[sampatch]

Hi, everyone—

I have a Sungold 2000 Watt inverter, and I can’t get AC power to work. It shows “Abnormal” on the display. It’s the same problem as in this thread. Any ideas? My breaker box is wired the same as the OP on that thread.

I don’t have it connected to shore power.

Thanks

Do you have a meter? Measure your input voltage both with inverter off and with it on, just to make sure that it's in the operating range. I would then disconnect all load wiring and check output voltage. If it needs a load to operate, find something like a lamp (100w incandescent) to plug in then check output voltage. Be careful, you're dealing with a lot of available power, both AC & DC.

I agree with Mr Nielson. Put your meter on it! Otherwise, went on line and read the manual and, not suprisingly, it does not address that error message. It has a 1 year warranty so can you return it? Finally, has it ever functioned ? A bad one out of the box seems all to common lately.

Remove all jewelery !

Thanks, folks. I’ll check all that out this evening. I can return/get the warranty coverage, so if I have to I can do that.

Hey, friends, we got it working. I checked all the connections and the plugged a hair dryer in while powering it up. It was too much, but it seemed to do something because now the lights turn on.

A new problem: the charger won’t charge. I don’t have a 30a outlet at my house, so I’m using an adapter. Could that be why?

[Rwnielsen]

You'll get it, one thing at a time

[sampatch]

Thanks. Any ideas on why the charger won’t cut on? There are a lot fewer variables here. Wired the inlet, plugged it in….and nothing.

As I wrote back last year : had the exact same issue with same inverter charger. I confirm that it needs to receive shore power before turning the inverter function on and deliver AC output.

I must have missed that thread. I have it working now, but it’s bouncing between float and fast charging every minute or so. Any thoughts?

What's the battery voltage when this is happening?

[sampatch]

It’s around 14, iirc. I’m not with it right now, but I can check later.

Sounds like your batteries could be full.


Any loads on the system at all? DC or AC.

[sampatch]

Yeah, I wondered that. I assumed they’d ship to me at less than full. There’s a little load, but only a very little.

I thought it would stay in float if they were full, though, but it’s trying to do both, like I said. I wonder if I should disconnect from shore power, use the batteries a while with tools and whatnot this weekend, and see what happens after I know for sure that they’re drained.

It sounds to me like you're hovering at the threshold between change and maintain. The small load only make it appear worse

All right, great. I’ll use it on some heavy stuff this weekend and see what it does.

Now would be a good time to calibrate my monitor, I assume.
