2 10 AMP to 30 AMP, will I end up with a 30 AMP 110 Volts or 30 AMP 220 Volts which I dont want....

It won't give you 220 but it will probably turn your inverter into scrap metal if they are separate circuits.

Sounds expensive.

Pay an electrician for his professional opinion.

Hi Joe,

How do you know the outlets are on different "circuits"?

There is an adapter for 15 amp dual outlets to 30 amp standard RV. If there really are "two circuits" and they are in sync, that might be used. If they happen to not be in sync you will let out the magic blue smoke.

Don't even think about it- that is a 2500 watt inverter, so 20 amps is all you will ever get out of it (other than the 5000 watt "peak", and a 20 amp breaker will handle a peak like that as long as the inverter will).

How about post the inverter model so we can read the specs. I doubt you can parallel the two separate sides of the inverter. Remote chance you could adapt the two sides to the two sides of your 50 amp main cord. Is only half power available to each inverter duplex?

Most likely you will be plugging into a single outlet. I am not sure this was the best inverter to buy. What do you expect to run? Do you have 400+ amp/hrs of battery?

This is what some of us do with our inverters but only plugs into one of the Inverter 120VAC receptacles.

I have two Inverters in my trailer one is 1500Watts and the other is 600Watts both are PSW... The 600W just has two multiport receptacles places in the trailer to plug into when I need "emergency" power. I dont have enough enough batteriey power to run my second 1500WATT invert to full power so I only really use it as a backup for the 600WATT one. I do however sometime plug the shore power cable into it to just gain access power to my trailer recepacles. I have to flip some breakers in the panel to keep from overloading the inverter when I do this however...

I want to add a flip lid connector near my shore power cable on the outside of the trailer which is wired to the 1500WATT Inverter. This way I could just use a short 15A to 30A adapter to power up the trailer when I do this...
would look something like this.... This is my poor man transfer switch
the center flip lid connector is my shore power connection - the flip lid ocnnector on the right goes straigth to the 1500WATT PSW Inverter.


If you could answer 2OLDMANs question he might have some more info for you. I'm thinking you will NOT be able to parallel those two sides of the 120VAC receptacles.. The manual should tell you... Maybe we can look that up on this side if we had the model number of the Inverter.

I'm still not following this.

Are you expecting 30a from this inverter by combining two sockets? Your inverter is only 2500w, that's not 3600 or 30a.

How do you know what each socket (alone) can provide?

Thanks for all the suggestions. My hope was to plug the shore power plug into my inverter, in lieu of a pedestal. By combining two 110 receptacles from the inverter ( I have 4) 2 per circuit. Using one plug from EACH circuit I would obtain 30AMP @ 110-120V.. Lazy way instead of wiring to the panel. The other thought is simply to use extension cords for boon docking.

Once you figure it is all safe to do around your family and this is what you really want to do this to your inverter then is what one dude on google search did to combine two Honda generators to a RV30A FEMALE connector. Since these type of things have hazards involved you usually can't find one already made up and you have to build your own. Should combine two separate 120VAC circuits into one RV30A circuit. I would contact the manufacturer of your Inverter to see if you can combine these two sides of the inverter receptacles. This is usually a trick the manufactures publish for a 2500 WATT Inverter which has two 1250WATTS circuits. They don't intend for you combining the two circuits together to get a full 2500WATS on one receptacle. Alot of portable generators do this as well. You think you have a certain wattage generator but you really have two lessor wattage circuits putting out half the wattage and you can't combine them. The other post is probably "right on" and it may go up in BLUE SMOKE doing this...





Use at your own risk I guess...

2 things - First, remember the second male plug will be hot if the first one is plugged into the inverter, creating a shock hazard. Second, if you tie both hots to the hot side of a 30 amp female connector you will not get 240V, but you may well get a fried inverter. While some inverter outputs can be paralleled, many cannot because the two outputs are not in sync.
