    12v DC to 110v AC inverter connection to a wall outlet?

    Hi all i have a 12v DC to 110V AC inverter that is currently connected to my battery bank. I would like to install a wall outlet in my shed where the battery bank is located off the inverter. The problem im having is that the inverter has two NEMA 15 plugs on it and no hardwire option. Could it be as simple as plugging in a male plug into one of the two plugs and cut the other end and wire it directly to an outlet ?

    Obviously the outlet will be grounded to the ground rod that i have next to the shed for the charge controller.

    Any input is appreciated.

    Why use a wall outlet when the inverter already has two?

    Unless you know exactly how to properly perform electrical wiring you can get hurt or cause an electrical fire.

    I would strongly suggest not to do what you intend to by using an extension cord that is "cut off" and wired to an outlet.

      definitely not going to do it if it's unsafe which is why im asking here.

      What would be the best way to put in an exterior light?

      I was going to buy this:
      Electrical supplies, residential and commercial lighting products, smoke detectors, electric motors and power/hand tools etc. for the electrical contractor, institutions, and the homeowner.


      and run 12 gauge wire from that (which will be plugged in to the inverter) to a single pole light switch, and from there to my exterior light. Do you think this is safer than putting a wall outlet??

        You could use a multi-outlet power strip that is plugged into the inverter and then use extension cords to each load. You can even get those cords with built in switches like they have for the Christmas lights so you don't have to unplug the one for your exterior light.

        Just don't over load the inverter, make sure the extension cords are at least #14 gauge wire (12 gauge is better), have them placed so they are not tripping hazards or can get damaged.

        Keep all the wiring as "temporary" so you can unplugged each load to work on it if needed safely.

          That is the fixture im getting, its meant to be connected to hard wire...i need to connect this to my inverter, so will the leviton adapter i linked you before work?

            One thing that would be handy if you end up hard wiring a receptacle in a wall box would be to get it in a different color than your standard receptacles (orange is nice!) to make it more obvious that it is not a grid connected receptacle.

              Get rid of the ground rod, it serves no purpose and not required. The reason is as you stated you have an Inverter made for mobile application and only has two Nema 15 amp plugs. Those twp plugs use GFCI sockets and no ground is required or needed. The Inverter could not possible deliver enough current to over heat any wiring. A Ground Rod would be completely useless and a waste of money.

                Actually the ground rod is for the Charge controller.

                So what is the solution to my issue now? i need to wire an exterior light to my inverter that has the GFCI sockets as you said.

                  Again the ground rod serves no purpose. They do not do anything.

                    Wish i would have known this before driving a 7 foot ground rod into the ground 6 months ago
