New inverter showing 100 percent load at only half the rated capacity

I just installed a new Must 6000W split phase, pure sign wave inverter. It seems to be working great, but I have noticed that the load percentage seems to be off. It gives a load percentage like to is set for a maximum of 3000W.

Today I finally put a heavy load on the inverter: about 3400 watts. It immediately went into overload falt and showed a load percentage of 110%. Any ideas on why it is showing 110% at only half capacity?

Update:
Ok, problem solved. I found out that the load percentage is the higher of the two phases. The inverter is rated at 3000w per phase, for a total of 6000w.

My old dryer was using 5600 watts!! That is 2800 per line/phase. I had some other stuff running as well, so the highest of the two phases was putting out 3400w or about 110%.

I have a lot to learn, but the inverter is working as it should.

Maybe it's a 6000watt PEAK inverter ?

Can you post a link to the item you bought please?

No, it is 15000w surge and 6000w rated power. I do not have a link , but he model number is: EP33-6048 TLV

With absolutely zero evidence to back it up....I'm going to say it has to do with only one phase being utilized....for some reason.

Caution: WAG

Do you have it set for 120v (and not 220v ?)

Lost in translation. Some people have trouble with split pase and do math wrong.

I knew an expert would be along shortly

Good question. I am running on both outputs, using some 120v appliances and some 240v. All that seems to be working well.

Question.....
Does using 240v AND 120v appliances at the same time make any difference?

The 120v should utilize single phase and the 240v 2 phase. I'm wondering if it's a built in limitation tothe inverter?
For example, you could go to 6000watts if everything was EITHER 120v OR 240v....but not mixed ?

Again...I'm making WAGS here but very interested in the topic.

If I am an expert on anything is is "lost in translation". That is only because I am married to a Chinese woman. Others have spoken about the useful capacity of many products being 50%.

You're welcome

Good to know. In any split phase system it is important to be balanced because the wire size is based on the same current whether 120 volts or 240 volts. It is good that your inverter tells you the Wattage or current on each leg.

what are the idle watts
