Automatic transfer swith (ATS)

[daromer]

ATS or Automatic transfer switch is something you can use to switch between grid an inverter or generator. In most solar systems that have booth inverter and charger like off-grid and hybrid systems already have an ATS built in. But if you want to build your own or just understand some parts of it I have so far 4 videos in this area.

There are a coupld of things to understand when doing this kind of load transfer. Like the fact that it takes 10ms. That you need proper contactors where both sources NEVER can be engaged at same time. The fact that if you dont synchronize the frequency you will get huge voltage spikes.

Hi, daromer. I got a problem here.

I am searching for ATS for diesel generator and I want to know if the ATS is set in the controller or control panel of generator or the ATS is set in another box seperately?

That depends on the setup yuu get. Normally for generator its a separate box that you have. With its own grounding since you need that for the generator. Atleast where I live thats how it is
