question about inverter
why most dc ac inverter(or converter) have a sockets ac outpout ,what if i want to distribute the ac power to a house for exemple?(many loads)

Most smaller AC inverters are designed assuming that you will plug the loads directly into the inverter.
Larger inverters tend to be designed to be hardwired to an AC Main Panel. Some inverters can be hardwired or on-board AC outlets depending on the needs of the installation.
What size of AC inverter do you want? Will you have to pass a building inspection?

And most MSW inverters will instantly smoke, spit fire and die if connected to an AC mains panel that has it's Neutral bonded to Ground.
did all ac mains panes has neutral bonded to ground?
what is msw inverter?
i want 1500w inverter ,and distrubute the power to a small ac mains panel that will power some loads?
By definition the bond is at the main panel. Modified Sine Wave(MSW) Most inexpensive inverters are MSW, These usually are design for mobile use and most with a few exceptions have neutral bonded, Xantrex's older DR line is the only exception I can think of.
- Assorted other systems, pieces and to many panels in the closet to not do more projects.
Just to be very clear... Generally MSW (Modified Square/Sine Wave) inverters will effectively be shorted if the battery is ground bonded and the inverter AC "Neutral" is ground bonded. And it will smoke the inverter.
TSW/PSW (True or Pure Sine Wave Inverters) usually have a full isolated transformer output. So, grounding one leg the DC input will not be affected by grounding the AC output "Neutral".
You have to check the inverter manual on grounding. There are exceptions to both of the above rules.
For TSW inverters (and generators)--Some have the white/neutral bonded inside the inverter (or generator). And others will "float" the AC output. In general, the larger the inverter/generator, the more likely the AC neutral will be grounded at the inverter/generator.
Ground bonding the AC neutral is common/standard in North America. In other regions, ground bonding requirements will vary.
In the US, many AC breaker panels will have a neutral bus that can be floated (plastic insulated bus) with a screw that can be inserted (ground bonding) or removed (floating) depending your needs.

ok thank you all
I believe you may be posting from Algeria? So you are looking for 230 VAC 50 Hz inverter/power system?
And what do you want to power (electronics, Air Conditioning, etc.)? And why do you want to do this (emergency backup, save money, afternoon/evening power outages are common, or what)?
MSW inverters are usually not going to be safe to connect/share with an existing AC power system and switching a "single leg" of AC. It can be done, but you need to switch both AC legs to isolate the branch circuits you wish to power.
Are you going to integrate an AC backup generator too?
Still lots of details to discuss/understand before you buy any hardware.
