My friend, this project is for small instruments that you do not want it to cut off, lick ADSL modem, when you are downloading a big file and fear from electrical loose, or for a small light, but in huge loads, it is better to use electrical generator, and this system well be in between of the instruments and generator

what kind of relay did you use?

[TheAroma2011]

You can use a relay according to your country voltage, here in my country I am using 220 volts relay, and it is lick switching, when the main AC id drown off, it engage to battery backup power, so your worl load well not affected.
