I want circuit charge the battery automatically
so,
when Electricity on inverter IS work
when Electricity off inverter is charge the battery automatically , when the battery full charge Stop charging the battery

I see! You want a circuit that would charge your battery....

I googled with "Automatic Battery charger schematics" and it came out with a lot of hits....:)

Are you using a lead-acid battery for your project?

Sounds like you need a charger that goes into float mode automatically. These require the specifications for the battery for use in designing. What voltage? What type? How many amp-hours?

The basic method is to build a high amperage charger with exactly the right voltage so the current becomes very small when the battery is fully charged.

I assume a Dried battery is "sealed lead acid".
This is too big for a really simple circuit.

You want to buy a float charger or design one?

Can not understand your request.
You want a low battery circuit to stop the battery when it gets low?

So let me see if I have this right. You want an automatic battery charger circuit for a sealed battery. You also want to use the sine wave inverter circuit you showed with the battery charger cicuit. So when the battery is charging the inverter is off and after the charge is complete the inverter turns back on. Is this correct?

after the charge is complete the inverter turns back on.
no when The return of electricity battery is charging when full battery off charging

now when cut of electricity inverter on

Okay. Now I have the picture of what you are doing. You are making an Uninterrupted Power Supply, a.k.a. UPS. Wouldn't it be easier, perhaps cheaper, to buy one? The schematic you are showing for the inverter section is only a 500 Watt inverter. You can quite possibly purchase a larger UPS for about the same money you would spend on making this one.

These are just a few of my thoughts please do not take offense to them. I am uncertain how you need to integrate everything together like you are wanting. Now that there is a clearer picture as to what you are trying to achieve, maybe some of the more knowledgeable members can help.
