	Dear Sir Domestic 3 phase supply system, one phase circuit invertor 700 VA 230 V is connected for emergency lights.Often invertor supply starts eventhough 3 phase supply is on during early morning around 3 am and automatically invertor supply is getting off after 2 hrs and reqular supply comes on that phase.What could be reason for invertor itself disconnect main supply and invertor supply getting on only on early morning time Sadasivam

	Most likely there is an automatic test routine programmed into the inverter/UPS. __________________ TANSTAAFL (If you don't know what that means, Google it - yourself)

	Another possibility is low/no voltage on the incoming supply around those times. However, it cannot be seen from here. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	May be under voltage or voltage dip. If undervoltage is only reason,it should happen any time of the day. Why only 2 am? Is it routine affair since installation? Is it happening only recently? The configuration of the inverter to be known before coming to conclusion __________________ Ramesh,Freelance Electrical/automation Consultant

	Try putting the invertor on another phase to see if the same thing happens __________________ The square root of nothing is what you make it!

	Another possibility is that you are being hacked by your neighbours. If the device is connected to the WLAN and the LAN WIFI passoword is 12345678 (the default provided by at least some companies in dwveloping countries), be aware that someone might be playing with ypur toy. __________________ Building the future!
