Inverter outlets

I am interested in powering an off grid cabin. The smaller inverters I see have multiple 15 or 20 amp outlets. When an inverter is rated for say 3000 watts but has only 2x15 amp outlets, I really can’t load more than 15 amps per outlet right? What I would need is an inverter I direct wire or one with a 30 amp outlet? I want to wire it to a small service panel.

Most larger inverters have multiple 15 amp outlets, BUT only 1 hard wired outlet. The hard wired outlet will pass the total inverter output

A good 3000w inverter will have a hardwire connection.

You can find a variety of 3kw inverters that are direct wire.

There are many cabin build threads that cover most of the questions you might have. I would start with that and ask questions.

Thanks for the replies. I looked closer at the various products and now see the hardwire connections. I may get an all in one anyway as it appears less expensive than individual components. I just need one with the right price and not a horrible stand-by load.

If this cabin is a temporary dwelling and rarely used you might want to go with an inverter/charger or just an inverter. Typically your all in ones are going to have a higher idle current simply because they give you more features. This may be a good thing if using routinely and you simply plan your supply (PV) to compensate for higher running load. Your cabin loads are something you need to get a grip on first to do any adequate planning

It is the same thing with planning your storage needs (batteries) some chemistries are better for particular usage than other. For intermittent use and freezing conditions AGM are likely your better bet. Daily use where freezing is not going to happen you can not beat LiFePO4. FLA may be a good choice if you are willing to do the maintenance and need to worry about freeze up.

Yes very easy to turn off the inverter and let the solar controller maintain the battery with virtually zero stand-by load.

I use a 2k 12v version of this - I use it as a UPS because of the 5ms switchover time which my server never has an issue with. And, it has a pretty low idle usage - has an 'eco' mode so it goes to sleep and just checks if there is a load periodically and turns on if there is.

Probably overkill for your purpose, but it is at 48v

3k12v (biggest I would do at 12v)

2k12v (I have this one as a UPS)


And, if you want to pay shipping I have these items that I am not using - you probably don't need this, but you haven't laid out your full design yet.


This is all top tier equipment - I got it for a green house that is going to be a few years until built, so I am selling it and will buy something then

I am about to post this the for-sale section as separate parts, just haven't gotten around to it.

Anyways you pay shipping and it is all yours for $800 - they are all new/oldstock never used. The paperwork is with them and the inverter is in a box, the others I would have to pack.

1 x Conext SW 2524, part number: 865-2524 (NIB)
1 x DC Switch Gear, part number: 865-1016 (NIB)
1 x AC Switch Gear, part number 865-1017 (NIB)

Do the all in one inverter/charger/controllers allow you to turn off only the inverter?

eg4 6000xp does.
