They resell a device made by Ziehl. It's a passive anti-islanding device.
It's a bit more than that. It checks...
Under- and overvoltage On three phase systems, phase to neutral and phase to phase. Under- and overfrequency Vector shift (I'll explain below) Rate of change of frequency (ROCOF) The first three are self-explanatory, but the other two are interesting. First, the last one (ROCOF). The anti-islanding switch will allow the frequency to drift as long as it doesn't drift too fast. If the frequency shifts very quickly from 50hz to 51hz, that's a bad sign, and it will disconnect.
Finally, Vector shift. When a mechanical generator (eg Diesel) runs at a constant pace the AC waveform crosses the zero point exactly every 0.01 seconds. If there is a sudden change in load, the engine might speed up or slow down and this will cause the waveform to shift slightly and miss the expected crossing point by a measurable angle. If this is too much, the switch will disconnect.

The Ziehl has two internal relays (redundant setup). These are used to drive external contactors. When used with a Victron Multiplus, you only wire up one of the relays, as the inverter itself already has LOM detection (loss of mains), as well as active anti-islanding.
Active anti-islanding: This is where the inverter actively tries to create a frequency or vector shift, but cannot succeed as long as its connected to the grid. Most countries requires at least one active component in your anti-islanding setup.

hoi, 
 
the update from the test version i had for the pip4048msd is not that big of a diff.
BUT its an update that is good and stable!
 
in general i am very very happy with the ICC program (1.1.4)
maybe a little tip (request),
the time to 100% is in hours in the ICC program.. when you add it via Emon its in Min.
maybe you can  make that Hours : Min too in Emon? (just like tha value of Time To Go)
 
final thoughts: you can't have a better program than ICC!! many, many thanks to Manie for the support and the updates!
your program Rocks!!!

thanks for the update / info riaanh

it is simular as my invertor pip4048MSD , only with 1 mppt tracker + if value (of some things) are 0 in emon, if the inverter doesnt know the command, it will be 0, don't use it in emon... its not that bad.. (and i see you do good in emon  , you only log what is needed)
 
but indeed if pvwatt1 is 0 , thats not good, if pvwatt2 is 0, thats normal , because you dont have 2 mppt trackers...
 
 

the problem was in the ICC version. Now I read all values. However mine is Mppsolar pip4048ms which is similar all'axpert. The connection is USB.

hoi,
 
here it works with usb to pi...
here i have a pip4048msd version...

Manie, i hope you will still return to the project and evolve from it.
you see you helped a lot of people , even me
the program is super good!
hope to see / download an update soon!
