I need to connect a device to disconnect when the mp looses grid.
I know that the ac out2 looses power when the grid is lost. But sometimes, my mp disconnects from te grid itself (i think because of overvoltage) and then is capable of reconnecting within a few seconds. This is a situation that i of course can not simulated.
“VRM message i get then is: ALERT - Alarm on ‘‘my site’’, parameter ‘Active input’ on ‘VE.Bus System [276]’, started” and not the standard grid fail message. So there is a difference.
My question: is does anyone know if the ac out2 is also switcht off when this situation occurs?
Is so, then i could just connect the device to ac out2. The device must immediately switch off when mp is disconnected from the grid.
I can now confirm that ac out2 akdo looses power when the mp disconnects because of other reason than gridfail.
I have made a small program on esp8266 that’s send an telegram message when power is applied to ac our2. So i get a message like “ac2 out on mp became active”.
So when this happens i know it was down. The actual message is then received though vrm of cource.
