Inverter wiring

I plan on connecting a samlex ssw2000 inverter to the shore power connection of the RV. Yes I will turn off the converter when using the inverter. I was reading the manual and it states " Do not connect the power inverter to household or RV AC distribution wiring" Warning : Do not connect directly to AC distribution wiring. Does this mean I can not use in the RV. Does this mean can not hook directly to the fuse panel , but can connect output of inverter to RV shore power AC input.

I connect my inverter to the shore power cord as you describe. Converter turned off to eliminate a charging loop (a $15 wireless switch inserted to the AC power cord to the converter).

I think the caveat messaged is regarding hardwiring into an existing circuit breaker panel or similar.

Unless I am missing something here, the AC output from the inverter should connect directly to the input side of the AC distribution panel, and should be "protected" by the main circuit breaker in that panel. The language you cite from your manual sounds erroneous to me. That's where the inverter should be connected.

UNLESS they are trying to tell you NOT to connect the inverter's AC output directly to an outlet, or series of outlets, without first going through the breaker box?

In any event, the manual is not very clear, IMO.

That is exactly what it means. Do not connect direct to wiring without going through the panel.

This inverter is a "Desk Top" inverter. It is intended to be wall mounted and contains two outlet plugs for the AC connection.


The statement in the manual is an attempt to prevent having the situation where the shore power lines are connected to the inverter output lines. This would be two AC sources tied together.....very bad.

The inverter is designed to allow you to plug in your desired device directly.
Connecting your RV to the inverter using the Shore Power cord is questionable because of how the common & ground wire may be bonded.
This is a quote from the manual:

The inverter is engineered to be connected directly to standard electrical and electronic equipment in the manner described above. Do not connect the power inverter to household or RV AC distribution wiring. Do not connect the power inverter to any AC load circuit in which the Neutral conductor is connected to Ground (Earth) or to the Negative of the DC (battery) source. WARNING: Do not connect directly to AC distribution wiring. This inverter is NOT grid interactive.

Regards,

Dan

My 2000 watt Inverter isn't a Samlex brand but I plug my shore power cord into it all the time and everything seems to work fine. I can even run my microwave off of the inverter.

That's is probably fine cause you cannot connect your power cord to external line power and to the inverter at the same time, thus not blowing anything up...

If you order a xantrax interter you can also order a transfer switch which allows a easy change of power from shore power to inverter but even then you got to remember to disconnect the converter.

every thing went well and works as expected. So now the question is were to put the inverter remote. The inverter is in the basement compartment to the left of the door. Just above that is the bench table. There is light switches on the back side of the bench as you enter the RV. If I want near the top of bench back means removing a panel. The other option is lower near the floor. If I had a longer cable I could run it to the fridge area in the wire tunnel. Any other ideas on were to put the inverter remote

I put mine in the main switch panel by the main door. Kind of a pain running the little control wire but not to bad.

Here is where I mounted the remotes for the inverters. The top right is for the 2000 watt and the smaller white remote panel is for the 1000 watt for the residential frig.

The inverters are mounted in the front storage where the batteries are located.

I really want to get a "whole trailer" inverter so my wife can use the hair dryer in the morning without me starting the generator. That and a few other things would be nice to run in the morning here and there when boondocking.

Is there a "how to" blog somewhere with good detail? I was considering getting a self contained 2000watt unit and plugging shore power to it but understand that if it has a GFI plug it won't work. I'd like to see the different options for this kind of install described to the layman. I can learn most anything but illustrations with descriptions is great.

Anyone know of a blog or post on this that is comprehensive?

Thanks
Darren

Bumps, you are wrong, the manual is correct. It has to do with the way the inverter is grounded, floating. If you hook the common wire to the white bus bar in your RV you will probably smoke the inverter. Some inverters can be hard wired. I hard wired mine and used a separate sub panel and transfer switch. I leave the circuits I am not using with the Xantrex in the coach panel, those I am going to use I move to the new sub panel. I run a fused 120 line from the current coach panel to the new transfer switch. The inverter goes into the gen/inverter site on the switch and out goes to the sub panel.

When plugged in to 120 all circuits are powered via the 2nd transfer switch and sub panel. When the generator is the source the same happens. When the inverter is the source the only circuits powered are those in the sub panel. Common wires are kept separate and going to the the correct place via the transfer switch.
