Adding a delay switch so that the inverter gets time to syncronize before switching back to grid. Crucial if you dont want to destroy your equipment.
-- More information below! --

In this video we add a delay switch so that when the grid or supply comes back it waits until the inverter had time to sync the frequenzy to the load before switching

I were not able to find any delay timers on Ebay... Below is the one Im using in the video

I have not added any drawing. On request I can do that but its simpy just to take existing one and add the delay up. Note that as I said in the video its important to understand how an inverter syncs to the grid and proper knowledge before installing.

Have fun!
