Automatic Load Transfer Switch(ATS) for Solar Power ...

mateen, as I read your posting you want to parallel the three supplies onto one bus bar simultaneously, is that correct? If so LOOK OUT.......how are you going to phase the ac supplies in? And the dc from the battery?

i cant pick any sense from your statement, but the question is what a hell do you want to do? its like you want to live on mars, saturn and earth at the same time

Solar battery? Do you mean AC supply from an inverter connected to a solar power battery bank?

You must or your aim is senseless.

If it is as I guess, then use qty2 2 way ATS. The first switches between utility and genset with normal ATS logic the second switches between the first ATS load side and the inverter then onto your bus on its load side. You need to have a longer switching dwell time on the second ATS to prevent nuisance switching when your utility goes down and the genset hasn't run up to speed and been switched to load by the the first ATS.

Otherwise get a three way ATS and set the controller up per the instructions on the can.
