Switching AC power??

Hello,

I want some way to switch 2 AC power outlets.

ie: Im continually charging 2 batteries. One goes down faster than the other. So I want an
easy way to FLIP the battery outputs. So Im using the fuller battery on the biggest load.

I hope thats clear.

Is this a DIY project? Or are their ready made switchers?

thanks

I am not following.

Are you running things off the batteries or just charging them? IF you are charging them there is no reason to turn them off unless you are afraid of over charging them.

im not talking about the charging per se. I want to switch / FLIP the 120 v outputs off the batteries.

battery 1 OUTPUT

Batteries are not 120v.
Do you mean 12v ........ or are you running inverters ?

If it is less than 15 amps use a three way switch.
Connect one input to each traveller screw. Connect the load to the common screw. Flip the switch to swap between inputs(traveller screws).

the lithium batteries have 120v INPUT CHARGING.

and 120 V OUTPUT

I run 2 machines off the batteries. One machine uses alot more power. so uses up that battery faster.

[ONE battery will have a greater load OUTPUT.]

So I want to switch the MORE CHARGED BATTERY to the higher load.

thanks

Ummmm.....Ok.

We're getting closer. We don't know and can't see what you have.
You have two battery packs/supplies and two loads you want to switch.
The following diagram assumes that the neutrals can be tied together from the two sources.
The switches are 15A or 20A household three way switches.

Ok..... now I'm really confused. Why can't you move the plug from one INVERTER to the other one ?

This is an example of a piece of equipment with two male plugs that is perfectly okay to construct and use,

(diagram credit: PJMax)

Each plug can be connected to one receptacle,, both receptacles, or nothing,

Each receptacle can receive power from only one plug at a time.

This device, which can be constructed on a small piece of plywood, offers the convenience of switching the load from one power supply to another without pulling plugs.

The parts in the blue box may be omitted if both power supplies will not be powering things at the same time.

Standard household (120 volt) receptacles and plugs should not be used for DC and/or low voltage applications such as connecting up power supplies with direct battery output.
