@Geoffburn

How have you programmed it?

If it have virtual switch enabled, that is probably the reason. (It is enabled by default)

Hi. I have a similar problem With Multiplus 24/3000/70-50. I used "input current limit control" assistant to control AC ignore. Multi sometimes doesn´t connect to grid, so it discharges battery. Today it happened and it also did not restarted after DC input voltage rised higher than DC input low restart voltage (this should have anything to do wit assistants, true?).

This non accepting grid happens only sometimes. AC ignore is controlled by DC input voltage and AC out power. If level for connecting to grid was higher, it worked well, but did not used battery capacity properly. After I set voltage for connecting lower, it started to do this again.

I´m still thinkig, if the problem is caused by wrong setting, but sometimes it works, sometimes not. So, maybe it is also something wrong with Multi...

When Multi is not accepting grid, there is ACognore = 0 on a VE configure. So, I accept, that assistant is "saying" that it should connect, but i doesn´t connect.
