I?m looking for a piece of hardware that will act as a knife switch for my entire house the idea will be to switch between battery (inverter) or grid power sources for my home using the device?s com port (rs232 or similar)Does anybody knows if this kind of device exists? just to clarify. thi is NOT a standard wifi power switch to turn a simple lamp On/Off it has to commute between sources up to 100 amps and 110V inputs of 3 phase AC current for my entire home.Any ideas or references?
Industrial power control stuff - not going to come cheap. Ask a good electrician (possibly one working for or with your power company) - also because installing that kind of stuff is non-trivial.
