I have an installation with a Quattro 48/5000 120V and want to add a programmable relay that turn on an LED alarm when overload pre-alarm to ultimately turn off the inverter through an external PLC. However, I am not sure how long I should put the delay. as I don´t know when exactly an overload pre-alarm is triggered. Anyone knows this?
Hi, I can’t directly answer you’re question but you might take a look at the ‘inverter overload webinar’.
My experience with overload is that its acting depends on different things as:
- how much overload it gets
- type of setup e.g. ESS, grid connected, stand alone
- when grid connected, is grid available or not
- programmed assistants
-etc.
In my case earlier with an multi 24/1600, grid connected with ignore AC assistant it shuts down within 7 seconds so it can’t even give a pre-alarm.
